can large separation has color metal, automotive, machine 床, table/sheet inner parts, bearings, solid parts, gears, elastic sheet/slice, pipeline, belt/tape parts, electrical water 煲, housing/shell, water device, water leading and other.
process features:
（1）POM processing front can use drying, most good in processing process in preheating (80℃ left right), for product dimensions stability property has benefits.
（2） POM processing temperature degree very narrow (0～215℃), in inner time long or temperature degree ultra- 220℃时就会 separation understanding, generate property strong/high aldehyde gas 体.
（3） POM material injection molding holding pressure pressure need relatively large (and injection pressure versus 近),以 decrease/reduce pressure drop. screw speed can high,残 amount need less;
（4） POM product shrinkage rate relatively large, easy generate sink marks or deformation.POM ratio hot large, mold temperature high (80～100℃), product demolding very 烫,需 anti 止烫伤手指.
（5） POM宜 in “ in pressure, in speed, low material temperature, relatively high mold temperature ” conditions lower molding processing, precision products molding use control mold temperature
(6) tool high machine strong/high degree and rigid property
(7) most high fatigue strong/high degree
(8) ring resistant property, resistant has machine solvent agent property 佳
(9) resistant impact property strong/high,良 good electrical property 质,复原 property good, tool already lubricated property, wear resistance good, dimensions property excellent.
