Common Problems in POM Plastic Processing and Solutions

Rotational molding
Rotational molding involves rotating a mold while hot database heating it to coat the inside with POM. This method is ideal for producing large hollow parts with uniform wall thickness.

3D printing
POM can be 3D printed using techniques such as fused filament fabrication (FFF) and selective laser sintering (SLS). Although less common than other materials, 3D printing with POM materials can create complex shapes and prototypes with high strength and durability.
Deformation and shrinkage
POM tends to warp and shrink during cooling, leading to dimensional inaccuracies. To minimize this, ensure good bed adhesion and use a heated bed for 3D printing. For injection molding, optimize cooling rates and use appropriate mold temperatures.

High printing temperatures
POM requires relatively high printing temperatures. Make sure your 3D printer can reach and maintain the temperatures needed to process POM. Use compatible filaments and adjust printer settings accordingly.

Post-processing
Although POM can achieve a smooth surface finish when printed, additional post-processing steps such as sanding or polishing may be required to meet specific surface quality requirements.

Conclusion
Polyoxymethylene (POM) is a versatile, high-performance thermoplastic that offers a unique combination of strength, dimensional stability, and ease of fabrication. Its properties make it suitable for a wide range of applications in a variety of industries, including automotive, household appliances, industrial machinery, medical devices, and food processing equipment.

By understanding the properties, applications and processing techniques of POM, designers and manufacturers can effectively use this material to create innovative, high-performance products.
