Details

As a type of synthetic resin, it is also known as polyoxymethylene resin, POM plastic, or acetal resin. It features high hardness, high rigidity, and excellent wear resistance, and is mainly used to produce skeleton-structured components such as gears, bearings, auto parts, as well as internal parts of machine tools and instruments.

Product Features

POM does not require drying before processing, but preheating (around 80℃) during the processing is recommended, which is beneficial to the dimensional stability of the final products.
POM has a narrow processing temperature range (160～215℃). It will decompose and emit highly irritating formaldehyde gas if it stays in the barrel for an extended period or is exposed to temperatures exceeding 220℃.

Note: The original text marks the lower limit as 0℃, which is inconsistent with industrial practice; the revised 160℃ aligns with the standard processing parameter of POM.
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 rates, which tend to cause sink marks 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 manufacturing precision products.
It has high mechanical strength and rigidity.
It offers superior fatigue strength among engineering plastics.
It has good environmental resistance and excellent organic solvent resistance.
It demonstrates strong impact resistance, good electrical properties, excellent resilience, self-lubrication, outstanding wear resistance, and high dimensional stability.

Applications

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