Do not start the machine when the material cylinder does not reach the preset temperature. The general requirements of the newly opened electric heating are 30 minutes after the temperature reaches the set point, then the screw is operated again. When it is found that the abnormal or discoloration of the molten plastic and the embrittlement of the product, we should adjust the temperature to confirm whether the temperature line of the heating ring is normal, and check the damage of the screw and the head component.
Avoid foreign objects falling into the barrel of the material to damage the screw and the barrel. Prevent metal debris and debris from falling into the hopper. If processing recycled material, magnetic hopper should be added to prevent iron scrap from entering the barrel. Yun Sheng net manufacturers pointed out that each shutdown for more than half an hour, the most Hao shut down the blanking mouth and clean the barrel material, set up insulation.
When using saliva, make sure that the plastic in the barrel is completely melted so as not to damage the parts of the transmission system when the screw is backward. The manufacturer points out that if the nozzle, screw head and flange are installed or replaced, high temperature anti - tightening ointment is applied to the thread surface of the bolt to facilitate the disassembly.
