Details

A type of synthetic resin, also known as polyoxymethylene resin, POM plastic, or acetal resin, featuring high hardness, high rigidity, and excellent wear resistance. It is mainly used in skeleton-structured products such as gears, bearings, auto parts, machine tools, and instrument internal components.

Product Features

POM does not require drying before processing, but preheating (around 80℃) during processing is recommended, which helps improve the dimensional stability of products.
POM has a narrow processing temperature range (0～215℃). If it stays in the barrel for too long or the temperature exceeds 220℃, it will decompose and produce highly irritating formaldehyde gas.
A relatively high holding pressure (close to the injection pressure) is required during POM injection molding to reduce pressure drop. The screw speed should not be too high, and the residual material should be minimized.
POM products have high shrinkage rate, which are prone to shrinkage or deformation.
POM is suitable for molding under the conditions of "medium pressure, medium speed, low material temperature, and relatively high mold temperature". Mold temperature control is necessary for precision product molding.
High mechanical strength and rigidity.
Superior fatigue strength among comparable materials.
Good environmental resistance and organic solvent resistance.
Strong repeated impact resistance, excellent electrical properties, good resilience, self-lubrication, outstanding wear resistance, and excellent dimensional stability.

Applications

POM can replace most non-ferrous metals and is widely used in auto parts, machine tool components, instrument internal parts, bearings, fasteners, gears, spring washers, pipes, conveyor belt accessories, electric rice cookers, pump casings, drainers, faucets, etc.

Replacing metal with plastic, we provide customers with optimal lightweight customization solutions. Based on the specific properties of POM materials, product structure, production quantity, and product color, we design tailored customization plans. The mold processing cycle is 25–30 working days; samples can be provided within 2 days after mold completion, and the delivery time is 7–15 days.
