Extrusion Process
When the storage environment is wet or the production surface is required to be high, the particles can be dried in a hot air hopper at 70 ℃ for 1-2 hours.
It can be processed by general injection molding machine. Because the difference between the actual temperature and the indicated value of the temperature control meter varies with the type of injection molding machine, users should choose the appropriate temperature according to the specific situation of the extruder . The following temperatures can be used as a reference for commissioning:
| Position | Feeding section | Middle section | Front section | Die section |
|---|---|---|---|---|
| Temperature | 160±10 | 180±10 | 190±10 | 200±10 |
