Square nut manufacturer by white & harder Delrin

Product Features

1. POM does not require drying before processing, but preheating (around 80℃) during processing is recommended, which helps improve the dimensional stability of products.
2. 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.
3. 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.
4. POM products have high shrinkage rate, which are prone to shrinkage or deformation.
5. 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.
6. High mechanical strength and rigidity.
7. Superior fatigue strength among comparable materials.
8. Good environmental resistance and organic solvent resistance.
9. Strong repeated impact resistance, excellent electrical properties, good resilience, self-lubrication, outstanding wear resistance, and excellent dimensional stability.
