What should you pay attention to when processing POM plastic?

September 30, 2019

Pay attention to the following when processing POM plastic :

1. POM can be used without drying before it is processed. It is best to preheat it during processing (about 80 °C), which is good for the stability of product size.

2. The processing temperature of POM is very narrow (0~215°C). When the residence time in the barrel is slightly longer or the temperature exceeds 220°C, it will decompose and produce stimulating formaldehyde gas.

3. The pressure of the POM material during injection molding is relatively 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 less;

4. POM products have a large shrinkage rate and are prone to shrinkage or deformation. POM is larger than heat and has a high mold temperature (80 to 100 ° C). The product is very hot when it is released from the mold, and it is necessary to prevent burns on the fingers.

5, POM should be molded under the conditions of "medium pressure, medium speed, low material temperature, high mold temperature", and the mold temperature should be controlled when molding precision products.

Application of POM plastic:

Can replace most non-ferrous metals, can be used in automobiles, machine tools, instrument internals, bearings, fasteners, gears, springs, pipes, conveyor belt accessories, electric water tanks, pump casings, drainers, faucets, etc.
