Embodiment Construction
[0020] see figure 1 , The molded product 10 of the present invention includes a soft layer 12 and a base 14 . The soft layer 12 is made of leather, fabric or cloth, such as natural leather, artificial leather, cotton fabric, fiber fabric, wool fabric, plastic fabric or nylon cloth. The soft layer 12 of this preferred embodiment is artificial leather, cotton fabric or nylon cloth. The soft layer 12 has a joint surface 122 which is joined to the base body 14 . The joint surface 122 is a rough surface or a rough surface, and has a plurality of rough surface structures or fine structures thereon.
[0021] The base body 14 is made of injection-molded material, and the injection-molded material is plastic, rubber or silica gel, wherein the plastic material can be polyvinyl chloride, polyethylene terephthalate, acrylonitrile-styrene Butadiene copolymer (ABS, acrylonitrile-butadiene-styrene), polycarbonate (PC, polycarbonate), polyimide, liquid crystal polymer, polyetherimide, polyp...

The invention provides a method for manufacturing a molded product, which comprises the following steps: providing a soft substrate, wherein the soft substrate is wound on a tape winder and any of leather, fabric and cloth; providing an injection mould, wherein the injection mould comprises a female mould and a male mould matched with the female mould; driving the tape winder, placing partial soft substrate between the female mould and the male mould; closing the female mould and the male mould, and enclosing the female mould and the male mould into a mould cavity; injecting a melted injection molded material into the mould cavity to form a matrix, and simultaneously integrally combining the injection molded material and the soft substrate positioned between the female mould and the male mould into a semi-finished product combined with the matrix and the soft substrate; rolling the tape winder after opening the mould, and moving the semi-finished product out of the mould; and cutting redundant soft substrate at the edge of the semi-finished product to form the molded product with a soft layer.
Description
technical field [0001] The present invention relates to a method of manufacturing a molded article, in particular to a method of manufacturing a molded article having a leather or fabric or cloth surface. Background technique [0002] With the development of mobile communication technology, a variety of electronic devices such as mobile phones are emerging, allowing consumers to fully enjoy the convenience brought by mobile technology anytime, anywhere. The aesthetics and tactile effects of these electronic device casings also More and more people's attention and attention. [0003] The casing is one of the main components of an electronic device, which is widely used in electronic devices such as telephones, computers, and game machines. Because plastic materials themselves have many advantages, such as light weight, low cost, relatively simple processing technology, and corrosion resistance, most electronic devices use plastic housings. [0004] In order to further make ...
