Common problems and solutions in processing UHMWPE special-shaped parts
Problem | Cause | Solution |
---|---|---|
Many wiredrawing and burrs during cutting | The tool is not sharp enough | Use carbide tools to keep the blade sharp |
Material deformation during processing | Cutting speed is too fast, friction generates heat | Reduce cutting speed and use air cooling |
Uneven edges of water jet cutting | Insufficient water pressure or insufficient abrasive | Increase water pressure and increase abrasive concentration |
Poor bonding after welding | The material surface is smooth and has low adhesion | Grind before welding to improve bonding |
Large dimensional error of special-shaped parts | Dimensional changes caused by thermal expansion | Consider the thermal expansion coefficient before processing and leave margin |
