POM plastic spacer

A type of synthetic resin, also known as polyoxymethylene resin, POM plastic, or "acetal resin" (commonly referred to as "steel substitute" in industrial contexts). It features high hardness, high rigidity, and excellent wear resistance. Primarily used in skeleton-structural products such as gears, bearings, automotive components, machine tool parts, and instrument internal components.

(1) POM does not require drying before processing, but preheating (around 80℃) during processing is recommended to enhance the dimensional stability of finished products. (2) POM has a narrow processing temperature range (0～215℃). It will decompose if exposed to prolonged residence time in the barrel or temperatures exceeding 220℃, releasing highly irritating formaldehyde gas. (3) High holding pressure (similar to injection pressure) is required during POM injection molding to reduce pressure drop. Screw speed should not be excessively high, and residual material should be minimized. (4) POM products have high shrinkage rates, making them prone to shrinkage defects or deformation. (5) POM is preferably processed under conditions of "medium pressure, medium speed, low material temperature, and relatively high mold temperature." Mold temperature control is necessary for precision product molding. (6) Exhibits high mechanical strength and rigidity. (7) Offers the highest fatigue strength among engineering plastics. (8) Excellent environmental resistance and organic solvent resistance. (9) Strong resistance to repeated impacts, good electrical properties, excellent resilience, self-lubrication, wear resistance, and superior dimensional stability.

Can replace most non-ferrous metals and is widely used in automotive components, machine tool parts, instrument internal components, bearings, fasteners, gears, spring washers, pipes, conveyor belt accessories, electric kettles, pump housings, drainers, faucets, etc.

We provide customers with optimal lightweight customization solutions through plastic-to-steel replacement. Based on POM's specific properties, product structure, quantity, and color requirements, we design tailored solutions. The mold processing cycle is 25-30 working days, with samples available within 2 days after mold completion, and a delivery time of 7-15 days.
