Selecting a Plastic for Your Injection Molded Part——POM

Commonly used materials for injection moulding parts——POM (Polyoxymethylene/ Polyformaldehyde)

• Benefits:

it is characterized by high toughness, stiffness, hardness and strength. Acetal has good lubricity and resistance to hydrocarbons and organic solvents. It also has good elasticity and is slippery, so it works well for bearing surfaces and gears.

• Applications:

gears, pumps and pump impellers, conveyor links, soap dispensers, fan and blower blades, automotive switches, electrical switch components, buttons and knobs.

• Considerations:

Due to shrink, customers must specifically design with uniform wall thickness. Painting and coating is difficult because of their lubricity. It’s also difficult to achieve a high-cosmetic finish. If a limited number of prototype parts are needed, it can easily be machined through Yeeshine company.
