Product processing guidance
- Demolition of the head, perforated plate, clean up; and emptying the retention material of the barrel
- And then heated to the default value, adding PVC modified material
- When processing is complete,, the first cooling to about 120 ℃, and drained the barrel material, and then turn off the power avoid to charred
- It is best to removed die, porous plate in time and clean up, so the next time will be more convenient to start.
2、 Processing technology reference
- The PVC modified soft materials must be dried before processed and the general dry condition is drying at 60-70℃ for 2-4 hours..
- Do not allow the material being contacted with dust or debris and stayed in the barrel for a long time during the production operation.
- Adjust the material processing temperature according to the different performance such as hardness and so on, the limited temperature is 170-190℃ generally.
