INJECTION OF PLASTICS

Injection molding - plastic molding technique consisting in injecting plasticized material into the mold, in which it solidifies (solidifies) in the so-called a molding (fitting). Injection molding (shortly: injection) is a cyclical process of processing plastics in the form of granules. There is also a variation of injection molding in which not the finished granulate is used, but a prepolymer and an agent causing it to polymerize during the molding process. This type of injection is called reactive injection molding. The injection molding process is carried out in special devices called injection molding machines. Injection is used to mold thermoplastics or thermosets.
