1. Screw wear
Reason: Hard impurities are mixed into the material, the screw and barrel are made of poor materials, and long-term use leads to wear.
Solution: Clean the material regularly to ensure that no impurities are mixed in; use high-quality screws and barrels; regularly check and replace severely worn parts.
2. Uneven melting of materials
Reason: Failure of the heating device, improper setting of the screw speed, and uneven mixing of materials.
Solution: Check the heating device to ensure accurate temperature control; adjust the screw speed to ensure that the material is fully melted; pre-mix the material before extrusion.
3. Poor molding
Reason: Unreasonable mold design, improper material temperature or pressure control, and cooling system failure.
Solution: Optimize mold design to ensure that the mold matches the product shape; accurately control material temperature and pressure; check the cooling system to ensure good cooling effect.
