There are several types of plastic products:
1. According to the forming method and product structure, it can be divided into compression molding products, transfer molding products, thermoplastic foam structural products, blow molding products, thermal forming products, non-waste forming products, rotating forming products, forging molding products, extrusion forming products, strengthening and laminating products, etc.
2, according to different raw materials can be divided into polyethylene, polypropylene, polyvinyl chloride, phenolic resin and amino plastic products.
3, according to the product geometry and use can be divided into plastic pipe, plastic film, plastic sheet and sheet, plastic wire, plastic belt.Plastic bags, artificial leather, plastic building materials, foam plastics, plastic containers, plastic shoes, electric wires, cables, plastic industrial parts, daily plastic products, plastic arts and crafts products and plastic products for culture, education and sports, etc.
The cooling time depends on the thickness of the product, the thermal and crystalline properties of the plastic, and the mold temperature.The end of the cooling time should be in place to ensure that products mold release when not cause changes for the principle, the plastic handle grip, cooling timeliness generally between 30 to 120 seconds, carry handle, cooling time is too long is not necessary, not only reduce the production efficiency, the complex parts will also cause demoulding difficulty, forced demoulding stripping stress even when other time and the production process of molding cycle is continuous and automatic and continuous and the degree of automation and so on.
