There are many methods of plastic forming. Six main forming methods are listed below: 1 injection molding and injection molding, extrusion molding. 2. extrusion molding, which is the main molding of thermoplastic plastic molding, 3 hollow blow molding, also known as the 4 compression molding also called compression molding. The upper and lower mold installation the template in the press on, the plastic material directly into the cavity, the mold is closed, full of plastic cavity in the heat and pressure, setting after plastic products. 5, injection molding and transfer molding. One of the main forming method is thermosetting plastics. It is feeding room, plastic pellets into mould in the heating, melting plastic under pressure through the pouring system of bottom mold transfer chamber fills the cavity, and then cure it. 6, solid molding molding plastics in melting temperature, in the molding process No obvious flow condition, for two times molding plastic sheet, such as vacuum molding, compression molding and air pressure molding, original for thin-walled parts molding, first used in the manufacture of thick wall parts. 7, other molding calendering, there are many casting plastic molding methods...
