1. Field of the Invention
The instant disclosure relates generally to a luggage bag and a forming method thereof, and pertains particularly to a luggage bag having customized patterns and the vacuuforming method thereof.
2. Description of Related Art
Conventional vacuum-molded plastic luggage bags are created in a molding device having integrally embedded patterns formed thereon. A flat thermoplastic substrate is heated and stretched onto the pattern-embedded mold through vacuuming. The plastic substrate is then cooled to form the desirable patterned shape of a bag. In general, the cost for creating a mold unit is often exceptionally expensive, and a permanent mold can only mass-produce products with a single pattern. Therefore, conventional vacuum molding techniques and the molding devices thereof fall short in providing the customization flexibility that modern consumers desire.
Embodiments of the instant disclosure provide a luggage bag having customized patterns and the vacuuforming method thereof.
A method in accordance with an embodiment of the instant disclosure provides a customizable vacuum molding method for forming personalized luggage bags utilizing a customizable vacuum molding device having a main mold body (1) and a personalized pattern module (2) customized to suit a customer preference, the vacuum molding method comprising the steps of:
1) placing the personalized pattern module (2) on a molding surface of the main mold body (1) at a predetermined location;
2) placing a plastic luggage bag substrate onto the molding surface of the vacuum molding device and soften the substrate by heating; and
3) generating negative pressure in the vacuum molding device and stretching the plastic substrate onto the personalized pattern module (2) on the molding surface of the main mold body (1) while cooling the plastic substrate to form a personalized pattern.
The method of creating the personalized pattern module (2) involves the following steps:
a. building a customer pattern database by gathering customer preference at a point of sale; and
b. utilizing a computer numerical control (CNC) cutting machine to create a plurality of personalized pattern modules (2) having different mold patterns according to the customer pattern database.
Preferably, the operational temperature range in step 2) is controlled between 200˜250 degrees Celsius, and the operational pressure range in step 3) is controlled between −0.60˜−0.65 MPa.
In order to enhance the three-dimensional effect a positive molding pattern, the personalized pattern module (2) may be shaped as an integral personalized pattern having uniform thickness, wherein the thickness is ranged from 1 mm˜10 mm. Alternatively, the personalized pattern module (2) may comprise at least two pattern portions of different thickness, wherein the thickness of each portion ranges from 1˜10 mm, thereby providing the customized pattern created there-from a sense of layer.
In order to enhance the concave effect of a negative molding pattern, the main mold body (1) may comprise a concave seating portion (11) for positioning the personalized pattern module (2), wherein the personalized pattern module (2) is a slab mold having a concave pattern (23) arranged thereon with the outer shape thereof coincidentally adaptable into the concave seating portion (11) of the main mold body.
A personalized luggage bag made by the instantly disclosed vacuum molding method comprises a bag body (2) having a customized pattern (3) designated by a customer, with the customized pattern (3) being an integrally formed portion of the bag body (5).
The customized pattern (3) on the personalized luggage bag may include words, pictures, symbols, or the combination thereof, preferably customized for the customers.
For positively molded patterns, the customized pattern (3) comprises at least one pattern portion, with each pattern portion being positively molded and protruding above the surface of the bag body (5) at substantially uniform height. Moreover, when the customized pattern (3) has more than one pattern portions, each of the pattern portions protrudes above the surface of the bag body (5) at different heights, thereby providing the customized pattern (3) a sense of layer
For negatively molded patterns, the customized pattern (3) may be concavely formed on the surface of the bag body (5), with the concavity of the customized pattern (3) being of the same or different depth.
Comparing with conventional techniques, the utilization of a cheaper temporary personalized molding module in combination with a permanent main mold body to form an integrated vacuuforming mold device provides a more customizable, flexible, and cost-effective molding solution. The replaceable design of the personalized molding module in the instantly disclosed vacuuforming method provides a simple yet cost effective solution for manufacturing luggage bags having personalized patterns of a customer's choice, providing brighter commercial future.
The instant disclosure will be described more specifically with reference to the following embodiments. It is to be noted that the following descriptions of preferred embodiments are provided herein for purpose of illustration and description. It is not intended to be exhaustive or limiting to the precise form disclosed.
Please refer to
The vacuum molding method for forming customized luggage bags in accordance with the instant disclosure is realized by utilizing a customizable vacuum molding device as illustrated in
1) First, place the personalized pattern module (2) of choice on a molding surface of the main mold body (1) at a predetermined location to form a temporary combination mold;
2) Then, place a plastic luggage bag substrate (6) onto the molding surface of the vacuum molding device and soften the substrate by heating. Preferably, the operational temperature range is controlled between 200˜250 degrees Celsius.
3) Subsequently, generate negative pressure in the molding chamber (7) of the vacuum molding device and stretching the plastic substrate onto the personalized pattern module (2) on the molding surface of the main mold body (1) while cooling the plastic substrate to form a personalized pattern. Preferably, the operational pressure range is controlled between −0.60˜−0.65 MPa.
For creating a luggage bag having a different pattern, simply take out the personalized molding module (2) of previous selection from the main mold body (1), replace it with another personalized molding module having a different pattern, and repeat the steps recited above to create the customized components for another personalized luggage bag with a different pattern style. The luggage bag components are subsequently put together through assembly lines to form the finalized product.
The fabrication of the personalized molding module (2) in accordance to the need of a customer may include the following steps:
a. build a customer pattern database by gathering customer preference at a point of sale, such as at a market place, a wholesale store, or a retail store. The customer preference database may contain customized patterns that are personally designed, or otherwise selected by a customer from a prepared list, or patterns that are particularly customized for the customer, and
b. according to the customer pattern database, utilize a computer numerical control (CNC) cutting machine (such as computer controlled laser cutting machine) to create personalized molding modules (2) having mold patterns of different styles.
The material for the personalized molding modules (2) may be of varying hardness, such as polyvinyl chloride (PVC) plastic, Thermoplastic polyurethanes (TPU) plastic, leather, acrylic, or cardboard. In general, personalized molding modules made of softer material are equally suitable for adapting onto flat and curved molding surfaces, while molding modules made of harder material are more suitable for adapting onto a flat molding surface. The thickness of the personalized pattern module (2) may range from 1˜10 mm, preferably between 1˜3 mm. In order to enhance the three-dimensional effect a positive molding pattern, the personalized pattern module (2) may be shaped as an integral personalized pattern having uniform thickness. Alternatively, the personalized pattern module (2) may be formed by combining two or more pattern portions of different thicknesses to further enhance the sense of layer in a resultant pattern.
