Insufficient '2079851475616104452 Machine Selection for PEEK
Fenómeno do problema
When ordinary '2079851475616104452 machines process PEEK, the temperature cannot reach the requirement or goes out of control, poor plasticization and degradation coexist, and the product qualification rate remains low for a long time.
Análise das causas
PEEK requires a barrel temperature of around 400℃ with high temperature control precision; ordinary '2079851475616104452 machines have insufficient heating power, temperature control zones, and thermocouple configuration; the screw compression ratio and material do not match PEEK characteristics.
Solução
①Select a high-temperature dedicated '2079851475616104452 machine or retrofit a high-temperature heating and temperature control system; ②Select a low-shear screw design suitable for PEEK; ③Use corrosion- and wear-resistant material for the barrel; ④Verify the equipment's actual temperature control capability before production.
Conclusão principal
PEEK's hard requirements for equipment cannot be compensated by process techniques; equipment selection mistakes are congenital defects; investing in high-temperature dedicated equipment is a prerequisite for PEEK projects.
