After shutting down, if there is material in the barrel, before restarting, the temperature of each single temperature zone must be raised to the required requirements according to the process requirements, and it can be started after insulation for more than 30 minutes. It is forbidden to start before the temperature reaches the requirements to avoid damage to parts. The bubble film machine should be regularly maintained, the material pipe should be thoroughly cleaned every three months, various bearings should be replaced with grease, and the reducer should be replaced with grease every six months.
Maintain the entire equipment once every two years. If the extruder screw is removed from the barrel for some reason, it should be properly handled to prevent deformation. If it is not installed back into the barrel for a long time, the extruder screw must be lifted vertically to prevent bumps, bending and permanent deformation. The surface of the barrel and extruder screw are coated with anti-rust agent for protection.
