1. Field of the Invention
The invention relates to a layered structure on an object and more particularly to a layered structure with pattern and a process of manufacturing same by using a computer numerical control (CNC) machine so that surface of the object can be colorful.
2. Description of Related Art
Conventionally, coating and/or spraying are performed on surface of an object (e.g., cabinet) made of plastic, aluminum alloy, or steel. Also, a pattern is formed on the surface of the object so as to render the object visually attractive.
However, the processes are time consuming and low in performance, and the pattern of one object may be different from that of another object after the processes. It is often that the object is discarded due to failure.
Thus, the need for improvement still exists.
It is therefore one object of the invention to provide a layered structure comprising a substrate including a first uneven surface on a top surface; a first coat layer having a predetermined color pattern and disposed on a top surface of the substrate; and a first material transfer layer having a predetermined inked pattern and disposed on a top surface of the first coat layer. A CNC machine is used to render the top surface of the substrate colorful.
It is another object of the invention to provide a process of manufacturing a layered structure, comprising the steps of (a) preparing a substrate which is aluminum alloy, magnesium alloy, or plastic; (b) using a CNC (computer numerical control) machine to move a metal brush along a predetermined direction to rub a top surface of the substrate to form a first uneven surface on the top surface of the substrate wherein hardness of the metal brush is greater than that of the substrate, and the metal brush is made of high hardness material which is alloy steel or tool steel; (c) using the CNC machine to control a coating device for coating a first coat layer on the top surface of the substrate wherein the first coat layer has a predetermined color pattern; (d) drying the first coat layer; (e) using the CNC machine to move the metal brush along a predetermined direction to rub a top surface of the coat layer to form a first uneven surface on the top surface of the substrate; (f) using the CNC machine to dispose a first material transfer layer having a predetermined inked pattern on the top surface of the coat layer; (g) drying the first material transfer layer at a temperature of 100-150° C. for about 30 minutes; (h) repeating steps (c) to (g) to form a second coat layer and a second material transfer layer sequentially; and (i) performing QC (quality control), packaging, and shipping.
The above and other objects, features and advantages of the invention will become apparent from the following detailed description taken with the accompanying drawings.
Referring to
A substrate 10, a first coat layer 20, and a first material transfer layer 30 are provided. The coat layer 20 has a thickness of about several micrometers. The first coat layer 20 has a predetermined color pattern. The first coat layer 20 can be PU (polyurethane) or PMMA (Polymethylmethacrylate). The first coat layer 20 is provided on the substrate 10. The first material transfer layer 30 is provided on the first coat layer 20. The first material transfer layer 30 has a predetermined inked pattern.
Referring to
Step 310: A substrate 10 is prepared for being colored. The substrate 10 is a material selected from aluminum alloy, magnesium alloy, or plastic.
Step 320: A metal brush is used to move along a predetermined direction to rub a top surface of the substrate 10 so as to form a first uneven surface 11. Hardness of the metal brush is greater than that of the substrate 10. Preferably, the metal brush is made of high hardness material such as alloy steel or tool steel. Preferably, washing is done on the substrate 10 for removing solution and oil remained after the rubbing.
Step 330: A coating device is used to coat a first coat layer 20 on the substrate 10 by using PVD (physical vapor deposition) or CVD (chemical vapor deposition). Thickness of the first coat layer 20 can be increased or decreased depending on requirements. Irregularities (e.g., projections and/or cavities) on the surface of the substrate 10 can be covered by increasing thickness of the first coat layer 20 printed on the substrate 10 so as to be visually aesthetic.
Step 340: The first coat layer 20 is dried for about 30 minutes. Temperature for drying the first coat layer 20 is about 180° C. if the first coat layer 20 is PU. Alternatively, temperature for drying the first coat layer 20 is about 90-180° C. if the first coat layer 20 is PMMA.
Step 350: An activation agent is sprayed on the first coat layer 20. Next, the first material transfer layer 30 is printed on the first coat layer 20 in a covering relationship by using water-based printing technology so that the substrate can be colorful.
Step 360: The first material transfer layer 30 is dried at a temperature of 100-150° C. for about 30 minutes. It is noted that the number of the first coat layer 20 and/or the number of the first material transfer layer 30 can be changed depending on requirements. Further, the first material transfer layer 30 may be disposed under the first coat layer 20 depending on requirements.
Step 370: QC (quality control), packaging, and shipping are done. Referring to
In step 350, an adhesive layer 31 is coated on the bottom of the first material transfer layer 30. Further, the first material transfer layer 30 is adhered to the first coat layer 20 by using thermal printing technology. The ink in the first material transfer layer 30 may deposit the predetermined inked pattern on the first coat layer 20 and change color of the first coat layer 20. Finally the first material transfer layer 30 can be released to render the top surface of the substrate 10 colorful.
