Injection Molding Parameters

Processing Item	Recommended Range / Condition	Notes & Explanations
Drying Treatment	Hot‑air drying above 80℃ for 16 h; if exposed to air＞8 h, vacuum‑dry at 105℃ for ≥8 h.	Critical operation. Keep moisture ≤0.2% to avoid hydrolysis, bubbles, silver streaks and mechanical‑property loss. Use immediately after drying or seal properly for heat preservation.
Melt Temperature	250‑280℃ for glass‑fiber reinforced grades.	Avoid temperature＞300℃ and long‑time residence to prevent material degradation.
Mold Temperature	80‑90℃ for structural and glass‑fiber‑reinforced parts; high mold temperature is also recommended for thin‑wall / long‑flow‑path parts.	Mold temperature greatly affects crystallinity and mechanical performance. Higher mold temperature improves crystallinity, stiffness and strength yet may reduce toughness.
Injection Pressure	750‑1250 bar.	Adjust according to product and mold design; higher pressure may be needed for GF‑reinforced material.
Injection Speed	High speed (slightly reduced for reinforced grades).	Fast filling helps cavity filling; excessive speed may cause uneven glass‑fiber orientation and poor venting.
Runner & Gate	Gate bore ≥0.5*t (t = wall thickness of molded part). For hot‑runner system, gate dimension shall be smaller than conventional runner. Minimum diameter for submarine gate ≥0.75 mm.	PA6 solidifies fast; gate location and dimension are critical.
Screw Speed	‑	Avoid excessive shear force to prevent glass‑fiber damage and material overheating.
Back Pressure	‑	Proper back‑pressure helps melt homogenization and venting.
Molding Shrinkage	Flow direction: ~0.3%; cross direction: higher value.	Obvious anisotropy; special attention required during mold design.
Shutdown Notice	Purge barrel with PE / PP of good thermal stability after production or shutdown to prevent carbonized nylon residue. Turn off heating system for long‑term shutdown.	‑
