注塑机合金料筒的日常维护与保养 Routine maintenance and maintenance of Zhoushan injection molding machine alloy barrel
1. When the barrel does not reach the preset temperature, do not start the machine.
2, to prevent metal fragments and debris from falling into the hopper, if processing recycled materials, you need to add a magnetic hopper to prevent iron filings from entering the barrel.
3. When using anti-salin, make sure that the plastic in the barrel is completely melted, so as not to damage the transmission system parts when the screw is retracted.
4. When using new plastic, the rest of the barrel should be cleaned.
5. When the temperature of the molten plastic is normal, but the black spots or discoloration of the molten plastic are continuously found, the rubber screw should be checked.
