Processing Parameters

Process Stage	Parameter Range	Technical Control Logic
Pre‑drying	100℃ × 3‑4 h	Drying air dew point ≤‑30℃, moisture content ≤0.015%
Barrel Temperature	Front 245℃ / Middle 235℃ / Rear 220℃	Avoid residence time＞5 min above 260℃
Mold Temperature	70‑90℃	Above 80℃ eliminates flow marks; below 70℃ tends to generate cold slugs
Injection Pressure	80‑120 MPa	Thin‑wall parts require holding pressure＞100 MPa for sufficient penetration
Screw Speed	50‑80 rpm	Back pressure 8‑12 MPa to prevent back‑flow
Molding Cycle	15‑25 s (wall thickness 1.2 mm)	High‑speed injection (filling time＜1.5 s)
