Q

PA6 Barrel Temperature Zoning

A

The barrel temperature gradient is the foundation for ensuring plasticization quality, and the compression zone must reach a sufficient melting temperature; after confirming effectiveness, fix the parameters and practices into the work instructions to prevent recurrence

Q

PA6 Nozzle Temperature Control

A

Nozzle temperature must be set in coordination with the melt temperature, and only combined with suck-back can both drooling and blockage be addressed; after confirming effectiveness, fix the parameters and practices into the work instructions to prevent recurrence
