Production method of plastic products
The production of plastic products generally includes plastic compounding, molding, processing, bonding, decoration and assembly. The four processes are carried out after plastic is molded into products or semi-products (also known as plastic secondary processing).
The key link of molding plastic processing in the production of plastic products, various forms of plastic (powder, granule, solution or dispersion) are made into products or blanks of desired shapes, and there are more than 30 molding methods. Its selection mainly depends on the type of plastic (thermoplastic or thermoset), the initial shape, and the shape and size of the product. Common methods of processing thermoplastics from plastics include extrusion, injection molding, calendering, blow molding, and thermoforming. While thermosetting plastics are usually processed by compression molding, transfer molding, and injection molding, lamination, molding, and thermoforming are used to shape plastics on one plane. The above plastic processing methods can be used for rubber processing. In addition, there are castings with liquid monomers or polymers as raw materials. Among these methods, extrusion molding and injection molding are common and basic molding methods.
The mechanical processing of plastic products draws on the processing methods of plastics such as metal and wood. Produces plastic products with very accurate dimensions or in very small quantities, and can also be used as an auxiliary process for forming, such as sawing extruded profiles.
Joints of plastic products, plastic parts processed by plastic are connected by welding and bonding. Welding is the use of hot air welding rods, hot air welding, high frequency welding, friction welding, induction welding, ultrasonic welding, etc. The bonding method can be bonded by adhesive, which is divided into flux, resin solution and hot melt adhesive bonding.
