How to increase the service life of injection molding machine screw?
How to increase the service life of injection molding machine screw?The screw is the main part of the injection molding machine. Its role is to transport, compact, melt, stir and pressure plastics. All this is accomplished by the rotation of the screw in the barrel. However, the screw of the injection molding machine is operated under high temperature, high pressure, high mechanical torque and high friction environment for a long time, and the loss cannot be prevented.
How to increase the service life of injection molding machine screw?
Methods to increase the service life of injection molding machine screw:
1. When the injection molding machine is started, the injection molding should be fully preheated;
2. The material and screw must match;
3. If the general machine corrosion materials must pay attention to the replacement with more stable materials such as HDPE, HIPS, etc.;
4. Every time the machine stops for more than half an hour, the blanking opening should be closed, the material in the barrel should be cleaned, and heat insulation should be set
5. Prevent foreign objects from falling into the material barrel and damaging the screw and barrel. Prevent metal fragments and debris from falling into the hopper. If the material is recovered during processing, a magnetic hopper must be added to prevent iron scraps from entering the barrel;
6. Prevent the screw from idling and slipping.
