Q:What are the main plastic forming processes?

3. cold pressing molding. Cold pressing molding is also called cold pressing sintering molding. The difference between the cold press molding and the ordinary compression molding is that the material is pressurized and molded at room temperature. The mold after release can be heated or cured by chemical action. This method is used in the forming of polytetrafluoroethylene and some high temperature resistant plastics (such as polyimide, etc.). The general process is three steps of billet sintering cooling.4. transfer molding. Transfer molding is a molding process for thermosetting plastics. When molding, the mold is heated and softened in the heating chamber and then pressed into the mold cavity where it has been heated. According to the different types of transfer molding equipment form: trap type; the tank; the piston.The requirement of plastic molding for transfer molding is that the plastic should have a greater fluidity before reaching the curing temperature, and the curing rate must be faster at the curing temperature. Phenol, melamine, formaldehyde and epoxy resins can meet this requirement.Transfer molding has the following advantages: less waste edge products, can reduce the processing quantity; second molding with fine or brittle insert and perforation of the products, and can keep the insert and the hole position is correct; the product performance is uniform, accurate size, high quality; the mould wear small. The disadvantage is that the manufacturing cost is high compression mold die; the plastic loss; the fiber reinforced plastics for fiber orientation and anisotropy; and around the insert around the plastic, sometimes due to melting is not strong and make the products according to the strength reduction.
