Plastic products fall into several categories:
1. According to the molding method and product structure, it can be divided into compression molding products, transfer molding products, thermoplastic foam structure products, blow molding products, thermal molding products, non-waste molding products, rotary molding products, forging molding products, extrusion products, reinforced and laminated 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 geometrical shape and use of the products 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, wires, cables, plastic industrial parts, daily plastic products, plastic arts and crafts plastic products and plastic products for culture, education and sports, etc.
The cooling time mainly depends on the thickness of the product, the thermal and crystalline properties of the plastic, and the temperature of the mold, etc.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 carrying, cooling timeliness generally between 30 to 120 seconds, plastic 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.
