Injection‑Molding Parameters

Process Parameter	Reference Range	Remarks & Instructions
Drying Treatment	80°C, 2‑4 hours	Keep hopper heated to prevent re‑moisture absorption; ensure moisture content below 0.1%.
Barrel Temperature	Rear zone:180‑200℃ Middle zone:190‑210℃ Front zone:200‑220℃ Nozzle:200‑230℃ (do not exceed 240°C to avoid material degradation)	‑
Mold Temperature	40‑70℃ (commonly 50‑60℃)	Higher mold temperature improves surface gloss and reduces internal stress.
Injection Pressure	Adjust according to flow length and part structure	‑
Holding Pressure	Approx. 30%‑60% of injection pressure	Optimize per wall thickness and structure to reduce internal stress and shrinkage.
Injection Speed	Medium or medium‑high speed	High‑speed improves gloss yet may cause flow marks; adopt slow‑to‑fast profile for high‑appearance requirements.
Screw Speed	Proper speed for uniform plasticization	‑
Back Pressure	0.5‑1.0 MPa	Facilitates uniform plasticization and degassing.
