POM injection molding process: Drying: If the material is stored in a dry environment, usually do not require drying. Melting temperature: homopolymer material is 190 ~ 230 ℃; copolymer material is 190 ~ 210 ℃. Mold temperature: 80 ~ 105 ℃. In order to reduce shrinkage after molding can choose higher mold temperature. Injection pressure: 700 ~ 1200bar Injection speed: medium or high injection speeds. Runners and Gates: You can use any type of gate. If you use the tunnel-shaped gate POMDE-20171, it is best to use a shorter type. Homopolymer material is recommended for hot runner nozzle. For internal use of copolymers can also be used outside of the runner runner. Chemical and physical properties of POM POM: POM is a tough elastic material, even at low temperatures are still very good creep properties, geometric stability and impact resistance. POM homopolymer materials have both copolymer material. Homopolymer material has good extension strength, fatigue strength, but not easy to process. Copolymers have good thermal stability, chemical stability and ease of processing. Both homopolymer material or copolymer materials are crystalline materials and are not easily absorb moisture. The high crystallinity of POM cause it has a fairly high shrinkage.
