Plastic injection molding, aka injection molding, is the primary molding method for thermoplastic materials. Injection moulding can be performed with a host of materials mainly including metals (for which the process is called die-casting), glasses, elastomers, confections, and most commonly thermoplastic and thermosetting polymers. Plastic injection moulds built in China, under the supervision of our Portuguese Engineers. Getting ready to design a complex plastic part? This Comprehensive Guide to Design for Manufacturing in Plastic Injection Molding can help with understanding the role of the design validation process prior to tooling kick-off, resulting in a reduction in overall manufacturing costs. However, other process parameters i. The yield and flow stresses in polymer increase with the increase in mold and melt temperature during injection molding. Molds are mainly made with NAK80,PAk90,S136,718H,P20,DF-2. Injection Blow moulding: The process of injection blow molding (IBM) is used for the production of hollow glass and plastic objects in large quantities.
