The characteristics of Yunnan Yuntianhua POM plastic raw materials:

(1) Before POM processing, drying is not necessary. Preheating (around 80 ℃) during the processing is beneficial for the stability of product dimensions

(2) The processing temperature of POM is very narrow (0-215 ℃), and it will decompose when it stays in the barrel for a slightly longer time or when the temperature exceeds 220 ℃, producing highly irritating formaldehyde gas

(3) When injecting POM material, the pressure maintaining pressure should be relatively high (similar to the injection pressure) to reduce pressure drop. The screw speed should not be too high and the residual amount should be less;

(4) POM products have a high shrinkage rate and are prone to shrinkage or deformation POM has a high specific heat and a high mold temperature (80-100 ℃), making the product very hot during demolding. It is necessary to prevent finger burns

(5) POM should be formed and processed under the conditions of "medium pressure, medium speed, low material temperature, and high mold temperature". When forming precision products, it is necessary to control the mold temperature

(6) High mechanical strength and rigidity

(7) Maximum fatigue strength

(8) Excellent environmental resistance and organic solvent resistance

(9) Strong resistance to repeated impacts, good electrical properties, good resilience, self-lubrication, good wear resistance, and dimensional stability
