Injection Molding
A mold temperature of 50 – 120°C is recommednded.POM is partilally crystallilnge thermoplastics and the mechanical properties are determined by the degree of crystallization which increases with the mould temp.
As with all crystalline polymers the follow-up pressure can be influential on the shrinkage of the part and a longer hold time is preferred to reduce shrinkage. MFI (190°C @ 2,16 kg) = 1 – 10 kg/10 min
POM is suitable for injection of thin wall & complex parts, MFI (300°C @ 21,6 kg) of 13 – 65 g/10min
