2. Screw, barrel and die of rubber extruder need to be heated. Generally, after the temperature reaches a suitable temperature, keep it for a period of time before turning it on.
3. Make sure to tighten the threaded connection of each part of the head at high temperature.
4, at the beginning of the extrusion, the screw speed should not be too fast, in case of overload, should be slowly accelerated.
5. Add a small amount of materials when starting, and gradually increase the amount of materials after each table value is stable.
6. If the parison is not molded at the entrance end of the molding die, a tool can be used to punch some small holes at the entrance end.
7. If the mold is blocked but not blocked, the setting table can be moved backward or the traction speed can be increased.
8. When the rubber extruder stops, it is necessary to clean up the excess materials in the barrel, then stop the machine, preheat the machine, take out the mold and clean it.
