(1) Without drying, POM can be preheated in the process (about 80℃), which is beneficial to the stability of product size.
(2) THE PROCESSING temperature of POM is very narrow (0 ~ 215 ° C). When the POM stays in the barrel for a long time or the temperature exceeds 220 ° C, it will decompose and produce strong formaldehyde gas.
(3) The POM injection molding pressure should be large (similar to the injection pressure) to reduce the pressure drop. The screw speed should not be too high and the residual amount should be small;
(4) POM has a large shrinkage rate, which is easy to shrink or deform.POM has a high specific heat and high mold temperature (80 ~ 100℃), so it is very hot to remove the mold, so fingers should be avoided.
(5) POM should be formed under the conditions of "medium pressure, medium speed, low material temperature and high mold temperature". Mold temperature should be controlled when forming precision products
