Drying: If the material is stored in a dry environment, it is usually not necessary to dry.
Melting temperature: homopolymer material is 190 ~ 230C; copolymer material is 190 ~ 210C.
Mold temperature: 80 ~ 105C. In order to reduce the shrinkage after molding can choose a higher number of mold temperature.
Injection pressure: 700 ~ 1200bar
Injection speed: medium or high injection speed.
Runners and gates:
Any type of gate can be used. If tunnel gates are used, it is advisable to use shorter types. A hot nozzle flow path is recommended for homopolymer materials. An internal hot runner can also be used for the copolymer material or an external hot runner.

Chemical and physical properties:
POM is a tough and resilient material that has good creep resistance, geometric stability and impact resistance even at low temperatures. POM has both homopolymer material and copolymer material. Homopolymer materials have good ductility, fatigue strength, but are not easy to process. The copolymer material has good thermal stability, chemical stability and is easy to process. Whether the homopolymer material or the copolymer material, are crystalline materials and difficult to absorb moisture.
The high degree of crystallinity of the POM results in a relatively high shrinkage rate of up to 2% to 3.5%. For different kinds of enhanced materials have different shrinkage.
