The scope of application of plastic products is quite wide. Plastic products are the unified name of life, industry and other products processed from plastic as the main raw material. Including plastics as raw materials for injection molding, plastic molding and other processes of products. Plastic is a kind of synthetic polymer material with plasticity. It forms three major synthetic materials that are indispensable for daily life with synthetic rubber and synthetic fibers. Specifically, the plastic is a material which is made of a natural or synthetic resin as a main component, is added with various additives, can be molded into a certain shape under a certain temperature and pressure, and has a constant shape at a normal temperature.

Plastic product mold production generally includes plastics in the formulation, molding, machining, joining, modification and assembly. The latter four processes are carried out after the plastic has been formed into a product or a semi-finished product, also known as plastic secondary processing.


The production of plastic products is the key to the processing of plastic molds. Various forms of plastic (powder, pellets, solution or dispersion) are made into articles or blanks of the desired shape. There are more than thirty methods of forming. Its choice depends mainly on the type of plastic (thermoplastic or thermoset), the starting form, and the shape and size of the product. Commonly used methods for plastic processing thermoplastics include extrusion, injection molding, calendering, blow molding, and thermoforming. Plastic processing thermosetting plastics are generally molded, transfer molded, and injection molded. Lamination, molding, and thermoforming are the shaping of plastic on a flat surface. The above plastic processing methods can be used for rubber processing. In addition, there are castings using liquid monomers or polymers as raw materials. Among these methods, it is used in extrusion and injection molding, and is also a *basic molding method.
