Injection‑Molding Parameters

Process Stage	Parameter	Recommended Range	Unit	Remarks
Pre‑drying	Drying temperature	80‑100	℃	Drying recommended; avoid bubbles & silver‑streaks, improve dimension & surface quality。
	Drying time	3‑4	h
Barrel temperature	Rear zone	170	℃	Narrow thermal processing window. Melt temperature ≤220 ℃, overheat causes formaldehyde decomposition。
	Middle zone	180	℃
	Front zone	190	℃
	Nozzle temperature	180‑210	℃	Close to / slightly lower than front‑zone temperature to prevent drooling。
	Melt temperature	190‑210	℃
	Mold temperature	60‑80	℃	Higher mold‑temperature improves crystallization, gloss and reduces sink‑marks。
Injection parameters	Injection pressure	50‑100	MPa	Adjust by part geometry & wall‑thickness。
	Hold‑up pressure	—	MPa	Adequate hold‑pressure required to compensate shrinkage。
	Back pressure	Low value	MPa	High back‑pressure induces shear‑overheat degradation。
	Injection speed	Medium, multi‑stage	—	Too‑slow: flow marks; too‑fast: jetting & shear heat。
	Screw speed	80‑120	rpm	Avoid excessive rotational speed to reduce shear heat。
	Barrel residence time	＜20‑30	min	Keep residence time short to prevent thermal degradation。
Shutdown procedure	Short‑term stop	Cool barrel below 150	℃	Long‑term shutdown: fully purge barrel with PE / PP。
	Purge note	PE / PP	—	Must purge halogen‑containing polymers before POM processing to prevent violent chemical reaction。
Post‑treatment	Annealing (optional)	—	—	Relieve residual stress for high‑precision parts working under non‑ambient service condition。
