1A to 1B are schematic cross-sectional views showing a manufacturing process of a molded article according to a first embodiment of the present invention.

Referring to FIG. 1A, a base layer 102 is provided. In the present embodiment, the base layer 102 may be, but not limited to, a micro fiber layer. The base layer 102 has a thickness of 0.2 cm to 0.3 cm. The novel creation can adjust the strength of the subsequently formed composite layer structure 110 (shown in FIG. 1B) through the base layer 102 of different thicknesses. Specifically, as the thickness of the base layer 102 is thicker, the strength of the composite layer structure 110 is also stronger.

Next, a reinforced film 114 is formed on the base layer 102. In the present embodiment, the reinforcing film 114 may be attached to the base layer 102, for example, by a glue layer. In an embodiment, the material of the reinforcement film 114 comprises a thermoplastic elastomer (TPE). The thermoplastic elastomer may be, for example, a thermoplastic polyurethane (TPU), a polyolefin-based elastomer (TPO), a polystyrene-based elastomer (TPS), or a combination thereof. When the base layer 102 is bonded to the reinforcing film 114, it can increase the hardness, strength, toughness and the like of the subsequently formed composite layer structure 110, so that the composite layer structure 110 is not easily damaged. In the present embodiment, the thickness T1 of the reinforcing film 114 is less than 0.03 mm (or 0.3). In an alternate embodiment, the thickness T1 of the reinforced membrane 114 is about 0.01 to 0.03 mm, for example 0.01 mm (or 0.1 strip). Basically, it is quite difficult to control the thickness of the thermoplastic elastomer (TPE) layer to 0.03 mm or less and to have a certain hardness, strength, toughness and the like.

In addition, after the reinforced film 114 is formed, a layer of the color treatment agent may be sprayed on the top surface 114t of the reinforced film 114, and a curing process may be performed, so that the top surface 114t of the reinforced film 114 is more easily colored and subsequently The formed pattern film 116 (shown in FIG. 1B) is not easily peeled off or peeled off. In an embodiment, the ripening treatment may be to adjust the temperature to 120 ° C to 140 ° C in a closed ripening chamber and to treat for 5 minutes to 10 minutes. In another embodiment, the ripening treatment may be to adjust the temperature to room temperature (about 25 ° C) in a closed ripening chamber and treat for 3 hours. In other embodiments, the ripening treatment may be to adjust the temperature to greater than 140 ° C in a closed ripening chamber and to treat for 5 minutes to 10 minutes to achieve a crystal sensation. In other words, the above-mentioned sensitizing film 114 having a crystal sensation can be completed by a aging process (the processing temperature is more than 140 ° C), and the subsequent hand-feeling treatment can be omitted to reduce the manufacturing cost. After the above-described aging treatment, the top surface 114t of the reinforcing film 114 (that is, the surface in contact with the subsequently formed pattern film 116) is a smooth surface.

Further, after the aging treatment, the handle treatment can be selectively performed so that the top surface 114t of the reinforced film 114 produces different effects such as various surface effects such as light feeling, fog feeling, velvet feeling, skin feeling, and silicone feeling. The handle processing can meet the needs of different users, thereby improving the commercial competitiveness of the products.

Referring to FIG. 1B, after the aging process, the pattern film 116 may be formed on the top surface 114t of the reinforced film 114 by a three-dimensional (3D) digital printing technique to form the composite layer structure 110. As shown in FIG. 1B, the reinforcing film 114 is located between the base layer 102 and the pattern film 116. In an embodiment, the pattern film 116 can exhibit various colors and patterns to increase the aesthetics of the molded article 10.

On the other hand, after the aging process, the composite layer structure 110 can be bonded to the workpiece 100 by, but not limited to, in-mold decoration technology to form the molded article 10. In particular, the in-mold decoration technique can include disposing the composite layer structure 110 in an in-mold decorative mold. In an embodiment, the in-mold decorative mold includes a hollow mold cavity. This cavity has a surface. Thereafter, the composite layer structure 110 is attached to the surface of the cavity such that the composite layer structure 110 covers the surface of the cavity. Then, the molding material is poured into the cavity of the in-mold decorative mold such that the molding material and the composite layer structure 100 are bonded to each other. In an embodiment, the molding material may be, for example, a suitable molding material such as a plastic material, a resin material, a metal material, a carbon fiber material, or a glass. Thereafter, the molding material is cooled to form the workpiece 100. The workpiece 100 is an application depending on the molded article of the present invention, and may be various workpieces such as a protective shell, a shoe material, a sports climbing article, a garment, a medical product, a box, and a snowboard. However, the novel creation is not limited thereto. In other embodiments, the workpiece 100 that can be attached to the composite layer structure 110 is protected by the novel creation.
