Plastic products processing is a process of converting raw materials into various plastic products through processing technology. Plastic products are widely used in various fields of daily life, such as household goods, daily necessities, electronic products, medical equipment, etc. The technology and process of plastic products processing continue to develop to meet people's needs for high quality, environmental protection, safety and innovation.

First of all, in the processing of plastic products, raw plastic is a very important part. The choice of plastic directly affects the performance and quality of the final product. At present, the common plastic raw materials are polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS) and so on. According to different uses and requirements, choose different plastic raw materials for processing.

Secondly, the processing of plastic products needs to be completed through a series of process steps. Common processing methods include injection molding, extrusion, blow molding, calendering, etc. Injection molding is the injection of molten plastic into the mold through the injection machine, through cooling and solidification to get the desired shape. Extrusion is the extrusion of molten plastic through the extruder, through the mold after cooling to obtain the desired shape. Blow molding is the process of blowing molten plastic into hollow plastic products through a blow molding machine. Calendering is the process of rolling molten plastic into a film or sheet. These processing methods can select suitable processes according to different needs to complete the processing of plastic products.

In addition, the processing of plastic products also needs to be processed according to different requirements. For example, for some large plastic products, cutting, grinding, polishing and other processes may be required to obtain better surface quality and dimensional accuracy. For some high-demand plastic products, surface treatment, such as spraying, printing, etc., is also needed to increase the aesthetics and additional functions of the product.

Finally, the processing of plastic products also need to pay attention to environmental protection and sustainable development. Plastic products may produce waste after long-term use, causing pollution to the environment. Therefore, in the processing process, it is necessary to rationally use raw materials, reduce waste generation, and rationally treat and recycle waste to reduce the negative impact on the environment.

In short, the processing of plastic products is a complex and diversified process, which requires the selection of appropriate raw materials and processing technologies according to different requirements and needs. At the same time, focusing on environmental protection and sustainable development, reducing waste to **, and being environmentally friendly is an important direction for plastic products processing.
