Embodiments of the present disclosure will be described in detail below. The embodiments described below are exemplary and are intended to explain the present disclosure only, but shall not be interpreted as limiting the present disclosure. For any part of the embodiments that are not indicated with specific techniques or conditions, the techniques or conditions described in literatures in the art or in product specifications may be followed. Any reagent or instrument whose manufacturers are not specified may be conventional product that can be obtained commercially.
According to an aspect of the present disclosure, an electronic device housing is provided. According to embodiments of the present disclosure, as shown in
To be noted that, in the present disclosure, the term “millimeter scale three-dimensional texture” indicates that a size in at least one of the three dimensions of the texture is millimeter scale, i.e., the size in the at least one of the three dimensions may be 0.1 mm to 10 mm. For example, a height of the texture or a line width of the texture may be millimeter scale. Alternatively, the height of the texture and the line width of the texture may both be millimeter scale.
It shall be understood that, a material of the housing body is not limited by the present disclosure, as long as the material can be applied to the electronic device housing. In detail, the material of the housing body may be glass, ceramic, and so on. In this way, the material may be available from a wide range of sources, a price may be reduced, and a signal shielding problem may be avoided, supporting application of 5G. In some embodiments, the material of the housing body may be glass. In this way, the material may be available from a wide range of sources, the housing may have good optical performance and have a low cost.
In detail, the millimeter scale three-dimensional texture may include a first three-dimensional texture and a second three-dimensional texture. In some embodiments, as shown in
In the present disclosure, it shall be understood that the terms “first” and “second” are used for descriptive purposes only and shall not be interpreted as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined by the “first” and “second” may expressly or implicitly include one or more of such features.
It shall be understood that, each of the first three-dimensional texture and the second three-dimensional texture described above may include a plurality of textured surfaces, and the plurality of textured surfaces of the first three-dimensional texture may be independent from the plurality of textured surfaces of the second three-dimensional texture. At least some of the plurality of textured surfaces intersect with each other. A first R angle is an angle of an intersection of two of the plurality of textured surfaces and has a radius greater than or equal to 0.2 mm Specifically, the radius of the R angle may be in a range of 0.5 mm to 3 mm, in a range of 0.2 to 1 mm, or in a range of 0.8 to 1 mm More specifically, the radius of the R angle may be 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 0.5 mm, 1.8 mm, 2.0 mm, 2.2 mm, 2.5 mm, 2.8 mm, 3.0 mm, and so on. As a result, each of the first three-dimensional texture and the second three-dimensional texture has an obvious angular structure, thereby providing a more stereoscopic appearance, a stronger visual impact, a better hand-holding feeling and anti-slip performance. The housing may be more fashionable and personalized, bringing the user a better experience.
To be noted that, in the present disclosure, the “R angle” refers to an angle of a transition arc at the intersection of two faces in two different directions, and the R angle has a radius. For example, the first R angle refers to an angle of a transition arc at the intersection of two of the plurality of textured surfaces, as shown in
It shall be understood that, as shown in
It shall be understood that, when the three-dimensional texture is not formed, the inner surface and the outer surface of the housing body are flat or curved, and at this moment, the surface of the housing body may be defined as a reference surface. Each of a bottom of the first three-dimensional texture and a bottom of the second three-dimensional texture intersects with the reference surface of the housing body. In some embodiments, as shown in
In detail, specific shapes and sizes of the first three-dimensional texture and the second three-dimensional texture are not particularly limited, and can be flexibly determined based on actual demands. In some embodiments, as shown in
In detail, cross-sectional shapes of the stripes of the first three-dimensional texture and the second three-dimensional texture may be various. In some embodiments, cross-sectional shapes of each stripe of the first three-dimensional texture and each stripe of the second three-dimensional texture may independently be triangular (as shown in
In detail, a size of the first three-dimensional texture and a size of the second three-dimensional texture of the electronic device housing is millimeter scale (0.1 mm to 10 mm). The texture in the size in the above range allows the user to intuitively have a strong stereoscopic feeling by naked eyes, and its difference with wavelength of visible light is relatively obvious, and therefore, interference, diffraction and other optical effects may not be generated. In this way, the user may directly feel a strong stereoscopic visual impact. In detail, the height of the first three-dimensional texture may be less than or equal to the height of the second three-dimensional texture. In detail, the first three-dimensional texture arranged on the inner surface allows the user to observe the stereoscopic effect by naked eyes. The texture, which has relatively small height, may be effectively identified by the naked eyes, and may be processed easily, allowing other components (such as a decorative film) of the electronic device to be assembled. At the same time, the texture allows the housing body to have a reduced thickness, enabling the housing to be thinner. The second three-dimensional texture located on the outer surface provides the user a stereoscopic visual impact. When the user is holding the electronic device, the user may directly feel the stereoscopic appearance and an anti-slip and anti-hand-falling effect. In order to ensure a more obvious stereoscopic tactility, the height of the second three-dimensional texture may be relatively large.
In some embodiments, the height H1 of the first three-dimensional texture may be in a range of 0.1 mm to 0.25 mm, more specifically in a range of 0.1 mm to 1 mm (such as 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, and so on). The height H2 of the second three-dimensional texture may be in a range of 0.1 mm to 2.5 mm, more specifically in a range of 0.5 mm to 2 mm, such as 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, 2.0 mm, and so on.
To be noted that, the description “the height of the three-dimensional texture” used in the present disclosure refers to a depth of the three-dimensional texture being recessed toward the inner side of the housing body or a height of the three-dimensional texture protruding toward the outer side of the housing body. In detail, the inner surface of the bottom wall being arranged with the three-dimensional texture may be taken as an example. When the three-dimensional texture is recessed toward the inner side of the housing body, any portion of the three-dimensional texture other than the recessed three-dimensional texture serves as a protruding portion. An inner surface of the protruding portion is located on a flat surface or a curved surface (i.e., the reference surface, indicated by the dashed part shown in
In some embodiments, each of the line width W1 of the first three-dimensional texture and the line width W2 of the second three-dimensional texture may independently be greater than or equal to 0.5 mm Specifically, the line width may be greater than or equal to 1 mm More specifically, the line width may be in a range of 1 mm to 10 mm or in a range of 1 mm to 2 mm, such as 1 mm, 1.2 mm, 1.5 mm, 1.8 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, and the like. To be noted that each of the first three-dimensional texture and the second three-dimensional texture may independently include a plurality of texture lines. The line width of each of the plurality of textures may be within the above range, but may be the same as or different from each other. In the above range, the textures may provide a stronger stereoscopic effect, the appearance of the housing may be better, and the housing may be easily processed. If the line width is excessively small, it may be difficult to process the housing, and the texture may be chipped and damaged. If the line width is excessively large, a more diverse appearance may not be achieved easily.
It shall be understood that, each of the first three-dimensional texture and the second three-dimensional texture may independently be a consecutive texture (as shown in
Further, the line width of the three-dimensional texture and the distance between two adjacent sub-textures may be determined in conjunction to facilitate film application to the housing body. In detail, the distance between two adjacent sub-textures may be small when the line width of the three-dimensional texture is large. The distance between two adjacent sub-textures may be large when the line width of the three-dimensional texture is small. In this way, the subsequent film attachment may be performed easily. In some embodiments, a ratio of the line width W1 of the first sub-texture to the distance L1 between two adjacent first sub-textures is less than or equal to 1:1, specifically may be in a range of 1:1 to 1:8, and more specifically may be in a range of 1:1 to 1:5, such as 1:1, 1:2, 1:3, 1:4, 1:5, 1:6, 1:7, 1:8, 1:9, 1:10, and so on. In some embodiments, a ratio of the line width W2 of the second sub-texture to the distance L2 between two adjacent second sub-textures is less than or equal to 1:1, specifically may be in a range of 1:1 to 1:8, more specifically may be in range of 1:1 to 1:5, such as 1:1, 1:2, 1:3, 1:4, 1:5, 1:6, 1:7, 1:8, 1:9, 1:10, and so on. In the above ratio range, the subsequent film attachment may be performed easily to enable the films to be attached to the housing body more properly, bonding there-between may be stronger, thereby achieving a more diverse and beautiful appearance.
In some embodiments, as shown in
To be noted that, the housing body may have different thicknesses at various locations (i.e., of uneven thickness). The maximum thickness of the housing body mentioned above refers to a thickness of a thickest location of the housing body, and the minimum thickness of the housing body mentioned above refers to a thickness of a thinnest location of the housing body. In some embodiments, the housing body may have substantially same thicknesses at various locations (i.e., of uniform thickness), as shown in
To be noted that, ideally, thicknesses of the housing body at the various locations may be identical. However, due to unavoidable accuracy and errors in the processing, it may be difficult to achieve identical thickness in practice. In the present disclosure, the description of “the housing body may have substantially same thicknesses at various locations” indicates that thicknesses at the various locations are exactly the same, or a difference in the thicknesses at various locations is within an allowable range caused by machining accuracy and errors.
In addition, an orthographic projection of the first three-dimensional texture and an orthographic projection of the second three-dimensional texture in a thickness direction of the housing body may be at least partially non-overlapping. In this way, both the first three-dimensional texture and the second three-dimensional texture may be directly seen by the user, and the housing may show a variety of appearances. In some embodiments, the orthographic projection of the first three-dimensional texture and the orthographic projection of the second three-dimensional texture in the thickness direction of the housing body may not overlap at all, or may be partially overlapping and partially non-overlapping. Further, the first three-dimensional texture and the second three-dimensional texture may be superimposed to form a complete decorative pattern. For example, the first three-dimensional texture may be a pattern of a star, and the second first texture may be a pattern of a moon, a sun and other planets. The two textures may be superimposed to form a decorative pattern of sky and the like. In this way, a variety of decorative patterns are achieved, and a strong special stereoscopic effect may be achieved.
It shall be understood that, as shown in
It shall be understood that, the decorative film may be a multi-layer structure. In detail, the decorative film may include a color layer, a texture layer, a bottom ink layer and a necessary bonding layer, and so on. Further, the decorative film may include a substrate film. The above-mentioned color layer, texture layer, bottom ink layer, and so on, may be arranged on the substrate film firstly and attached to the inner surface of the housing subsequently. A specific structure and material of the decorative film may be determined based on the desired appearance of the housing, and will not be described in detail herein.
In some embodiments, various slopes with surfaces are arranged. The outer surface of the glass housing body, which is arranged with the second three-dimensional texture, may be disposed on the slope and face the slope. Subsequently, an angle of the slope may be continuously increased until the glass housing body starts to slide down. An angle of the slope at which the glass housing body starts to slide down may be recorded. A test result shows that the angle of the slope at which the housing body arranged with the millimeter scale three-dimensional texture starts to slide down is more than eight times of the angle of the slope at which a flat glass without the three-dimensional texture starts to slide down. In an embodiment, as shown in
According to another aspect, the present disclosure provides a method of manufacturing the electronic device housing. According to the embodiments, the method includes following operations. A molding process may be performed on the substrate to obtain the housing body. The housing body includes a bottom wall and at least one side wall connected to the bottom wall. An outer surface of the bottom wall is flat or curved, and an outer surface of the side wall is curved. At least part of the surfaces of at least one of the bottom wall and the side wall is arranged with a millimeter scale three-dimensional texture. Operations of the method may be simple and may be performed easily. The method may be performed highly in automation and can achieve a high processing accuracy. The processing technology is mature, and can easily achieve industrial production of the housing. At the same time, the obtained housing can provide the user a strong stereoscopic effect both visually and tactilely, meeting the requirements of fashion and personalization, and enabling the user to have better usage experience.
In some embodiments, the substrate may be glass. The molding process may include following operations. The substrate may be placed in a mold, and a hot forging process may be performed at a predetermined temperature on the substrate to obtain the housing body. The predetermined temperature may be 100 degrees Celsius to 150 degrees Celsius lower than a softening point of the substrate (in detail, such as 100 degrees Celsius, 110 degrees Celsius, 120 degrees Celsius, 130 degrees Celsius, 140 degrees Celsius, 150 degrees Celsius, and so on, lower than the softening point). According to the present method, the surface of the glass substrate may be processed to form a new shape. In detail, the surface may be converted from a flat surface to a stereoscopic three-dimensional structure (i.e., the three-dimensional texture arranged on the surface), allowing the electronic device housing to have a stereoscopic structure and appearance, significantly diversifying the appearance of the electronic device housing and significantly improving the aesthetics and user experience of the electronic device housing.
In detail, the above temperature range may allow a clear three-dimensional texture to be formed, and may significantly reduce a molding mark. If the temperature is excessively low, a clear texture may be not be formed by the hot forging operation and may be fragmented easily, and a size and profiling of computer aided verification (CAV) of the texture may not be controlled properly. If the temperature is excessively high, the molding mark may be severe, increasing the difficulty of a subsequent sweeping process (such as sweeping for a long time causing the texture to be collapsed, sweeping for a short time being unable to remove the molding mark), and at the same time, oxidation of the mold may be accelerated (about 5%-8%). It shall be understood that, the temperature range can be adjusted properly based on the glass material of the substrate and various texture effects in combination of practical experience. Generally, the thicker the glass, the higher the temperature. When the glass material is changed, the temperature may be determined based on a softening point of the glass. In detail, for example, a softening point of the Corning glass is 880 degrees Celsius, and the temperature of its hot forging operation may be 730 degrees Celsius to 780 degrees Celsius. A softening point of the NSG glass is 700 degrees Celsius, and the temperature of its hot forging operation may be 550 degrees Celsius to 600 degrees Celsius. A softening point of the AGC glass is 770 degrees Celsius, and the temperature of its hot forging operation may be 620 degrees Celsius to 670 degrees Celsius.
It shall be understood that, the present disclosure does not specifically limit the glass material, any glass that meets requirements for manufacturing the electronic device housing may be applied. For example, the glass material includes, but is not limited to, high aluminum-silica glass, soda lime glass, lithium-aluminum-silica glass, and so on. Specifically, the glass may be the Corning glass, the AGC glass, and so on. In detail, a thickness of the glass substrate may be 0.5 mm to 1 mm (specifically, such as 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, and so on). In the thickness range, the glass substrate may have better strength, complex and diverse three-dimensional textures may be achieved easily, and the stereoscopic effect may be better. If the thickness is excessively large, a relatively simple three-dimensional texture may be formed, and the stereoscopic effect of the three-dimensional texture may be relatively weak. If the thickness is excessively small, the housing may be fragmented easily, and strength requirements of the housing can hardly be met.
In detail, detailed hot forging operation may refer to placing the glass substrate in a molding cavity of a mold and pressurizing a closed mold at a molding temperature, such that the glass substrate is molded into a target shape (specifically, such as a three-dimensional texture). In detail, the mold for hot forging the glass substrate may include an upper mold and a lower mold. A temperature of the upper mold and a temperature of the lower mold in the hot forging operation may both be within the temperature range described above, and the temperature of the upper mold is greater than the temperature of the lower mold. In this way, the temperature may be suitable, the formed three-dimensional texture may be clear, the molding mark may be slight or even absent, no small and large edges may be formed, and dimensions may be precise. It shall be understood that the specific temperature may be adjusted properly based on the glass material, the structure and the CAV profile of the three-dimensional texture. To be noted that, the temperatures of the upper mold and the lower mold described herein refer to a temperature of a preheating operation and a temperature of a hot forging station in the hot forging operation, and a temperature of a subsequent slow cooling operation is not included.
It shall be understood that, as shown in
It shall be understood that, in the hot forging operation, a magnitude of the pressure may have a certain impact on the molding process. In some embodiments, the pressure of the hot forging process may be greater than or equal to 80 Kg and less than or equal to 200 Kg. More specifically, the pressure may be greater than or equal to 80 Kg and less than or equal to 140 Kg, such as 80 Kg, 90 Kg, 100 Kg, 110 Kg, 120 Kg, 130 Kg, 140 Kg, 150 Kg, 160 Kg, 170 Kg, 180 Kg, 190 Kg, 200 Kg, and so on. Within this pressure range, a better stereoscopic effect of the texture may be achieved by the hot forging operation, the molding mark may be slight, and a service life of the mold may be increased. If the pressure is excessively large, the glass may be deformed easily and broken into pieces, the service life of the mold may be reduced, and the molding mark may be severe, such that time spent for performing the subsequent sweeping process may be increased, the sweeping efficiency may be reduced, and costs of the sweeping process may be increased. In a case of a same time duration and a same temperature being applied, if the pressure is excessively small, it may be difficult to form the three-dimensional texture by pressing, fragments may be generated easily, and the mold may be damaged. Of course, it shall be understood that the pressure range may be adjusted properly based on glass materials and the three-dimensional texture structure, in combination with practical experience and other parameters such as time.
In detail, the hot forging and molding process may specifically include three processes: a heating process, a shaping process and a cooling process. Each of the above processes may involve a plurality of working stations. According to the present disclosure, time duration of the entire hot forging and molding process may be greater than or equal to 20 minutes and less than 40 minutes (specifically, such as 20 minutes, 21 minutes, 25 minutes, 28 minutes, 30 minutes, 32 minutes, 35 minutes, 36 minutes, 38 minutes, 39 minutes, and so on). Further, time duration of each of the plurality of working stations in the hot forging and molding process may be 50 seconds to 150 seconds, more specifically may be 65 seconds to 120 seconds, such as 50 seconds, 55 seconds, 60 seconds, 65 seconds, 70 seconds, 75 seconds, 80 seconds, 85 seconds, 90 seconds, 95 seconds, 100 seconds, 105 seconds, 110 seconds, 115 seconds, 120 seconds, 125 seconds, 130 seconds, 135 seconds, 140 seconds, 45 seconds, 150 seconds, and so on. In the above time range, a clear three-dimensional texture may be formed in a short time period, and a high processing efficiency and yield may be achieved. If the time duration is excessively short, the formed three-dimensional texture may not be clear, and the precision may be low. If the time duration is excessively long, the texture may be formed in an excessively long period of time, and the molding mark may be severe, reducing the efficiency and increasing the costs.
In some embodiments, the molding process may include following operations. The substrate is provided, and the substrate has an inner surface and an outer surface opposite to the inner surface. CNC machining may be performed on the substrate. The CNC machining includes following operations. A portion of the substrate is removed from the inner surface, such that a bottom wall and at least one side wall connected to the bottom wall are formed on the substrate. A position of the outer surface of the substrate corresponding to the side wall may be machined to be curved. The millimeter scale three-dimensional texture may be formed on at least a part of the surface of at least one of the bottom wall and the side wall. The method is carried out by performing the CNC machining. Operations may be simple, and may be easily performed. The method may be highly automated, and the processing accuracy may be high. The CNC machining technology is mature, and industrial production may be achieved easily.
It shall be understood that, in the CNC machining process, the present disclosure does not limit an order of performing the operations of removing a part of the substrate from the inner surface, forming the three-dimensional texture, and processing the outer surface. Removing a part of the substrate and forming the three-dimensional texture may be performed firstly, and subsequently, the outer surface may be machined to be curved. Alternatively, the outer surface may be machined to be curved firstly, and subsequently, a part of the substrate may be removed, and the three-dimensional texture may be formed. The order of performing the above operations may be flexibly adjusted based on the needs.
It shall be understood that, the CNC machining may further include following operations. The outer surface of the substrate at a position corresponding to the bottom wall may be machined into a curved surface. In this way, the housing having a 3D structure may be obtained.
In detail, when the three-dimensional texture is arranged on the inner surface of the housing body only, the molding process may include following operations. The substrate may be provided to have an inner surface and an outer surface opposite to the inner surface. CNC machining may be performed on the substrate. The CNC machining includes following operations. A portion of the substrate may be removed from the inner surface, such that a bottom wall and at least one side wall connected to the bottom wall may be formed on the substrate, and the millimeter scale three-dimensional texture may be formed on at least one of the inner surface of the bottom wall and the inner surface of the side wall. The outer surface of the substrate at a position corresponding to the side wall is machined to be curved.
In an embodiment, a flat substrate may be provided firstly. Subsequently, the three-dimensional texture may be formed on the inner surface of the substrate by the CNC machining Subsequently, the outer surface corresponding to the side wall may be machined to be curved by the CNC machining.
In another embodiment, a flat substrate may be provided firstly. Subsequently, the CNC machining may be performed to obtain the bottom wall and at least one side wall connected to the bottom wall on the substrate and to form a three-dimensional texture on the inner surface of the substrate. Subsequently, the resulting product may be fixed on a jig having a shape copying the three-dimensional texture (specifically, a 3D base of the jig having the profiled texture). Further, the machining process may be performed to machine the outer surface corresponding to the side wall to be curved and to form the three-dimensional texture on the outer surface corresponding to the bottom wall.
In detail, when both the inner surface and the outer surface of the housing body are arranged with the three-dimensional textures, the molding process may include following operations. A substrate may be provided to have the inner surface and the outer surface opposite to the inner surface. A first CNC machining process may be performed on the substrate. The first CNC machining process includes following operations. A portion of the substrate may be removed from the inner surface, such that the bottom wall and at least one side wall connected to the bottom wall are formed on the substrate, and the first three-dimensional texture may be formed on at least one of the inner surface of the bottom wall and the inner surface of the side wall. A second CNC machining process may be performed on the substrate having been treated by the first CNC machining process. The second CNC machining process includes following operations. The outer surface of the substrate at a position corresponding to the side wall may be machined to be curved. A portion of the substrate may be removed from the outer surface, such that the second three-dimensional texture may be formed on at least one of the outer surface of the bottom wall and the outer surface of the side wall. While performing the method, the CNC machining process is performed. Operations may be simple, and may be easily performed. The method may be highly automated, and the processing accuracy may be high. The CNC machining technology is mature, and industrial production may be achieved easily.
It shall be understood that, while performing the second CNC machining process, the present disclosure does not limit an order of the operation of removing the part of the substrate from the outer surface to form the second three-dimensional texture and the operation of processing the outer surface of the substrate at a position corresponding to the side wall to be curved. A part of the substrate may be removed to form the second three-dimensional texture firstly, and subsequently, the outer surface at a position corresponding to the side wall may be machined to be curved. Alternatively, the outer surface at a position corresponding to the side wall may be machined to be curved firstly, and subsequently, a part of the substrate may be removed to form the second three-dimensional texture. The order of the operations may be flexibly adjusted based on the needs.
It shall be understood that the above method may further include following operations: the outer surface of the substrate at a position corresponding to the bottom wall is machined to be curved. In this way, the housing with a 3D structure may be obtained. In detail, the present operation may be performed before or simultaneously with the operation of forming the second three-dimensional texture.
In detail, before the second CNC machining process, the substrate having been treated by the first CNC machining process is fixed to a jig. A surface of the jig contacting the substrate is arranged with a profiled three-dimensional texture complementary to the first three-dimensional texture, such that the first three-dimensional texture may be fixed with and fit into the profiled three-dimensional texture. Therefore, the substrate arranged with the first three-dimensional texture may be better fixed, and the profiled three-dimensional texture may fit well with the first three-dimensional texture without damaging the first three-dimensional texture.
To be noted that, the expression of “a profiled three-dimensional texture complementary to the first three-dimensional texture” in the present disclosure shall be interpreted as the profiled three-dimensional texture being complementary to the first three-dimensional texture, specifically indicating that sizes of the first three-dimensional texture and the profiled three-dimensional texture and tendencies of protruding and recessing at corresponding positions (i.e., for the substrate being fixed to the jig, positions of the jig and the substrate that need to contact each other) may be substantially the same. When the substrate is fixed to the jig, the three-dimensional texture may be placed exactly in the profiled three-dimensional texture, and almost no gap is defined there-between at the positions where the jig and the substrate contact each other.
In detail, detailed operations and parameters of the CNC machining process may be flexibly adjusted based on a structure and a pattern that are desired to be achieved, and will not be described herein. The ordinary skilled person in the art shall understand that the method may be performed to prepare the electronic device housing described in the above. The features and advantages may be referred to the corresponding description in the above, and will not be described here.
In an embodiment, a flat substrate may be provided firstly. Subsequently, the first three-dimensional texture may be formed on the inner surface of the substrate by the CNC machining process. Subsequently, the obtained substrate may be fixed on a jig having the above-mentioned profiled three-dimensional texture (specifically, on a 3D base of the jig having the profiled texture). Further, a further CNC machining process may be performed on the outer surface corresponding to the side wall, such that the outer surface corresponding to the side wall may be curved, and the second three-dimensional texture may be formed on the outer surface corresponding to the bottom wall.
