Injection‑Molding Parameters

表格

Process Stage	Parameter	Recommended Range	Unit	Remarks
Pre‑drying	Drying temperature	80‑90	℃	Drying recommended for wet raw material, stabilize production & surface quality。
	Drying time	2‑4	h
Barrel temperature	Rear zone	150‑170	℃	Narrow thermal‑processing window. Melt temperature ≤220 ℃, overheat causes formaldehyde decomposition。
	Middle zone	170‑190	℃
	Front zone	180‑200	℃
	Nozzle temperature	170‑190	℃	Slightly lower than front‑zone temperature to prevent drooling。
	Melt temperature	190‑210	℃	Typical working range for copolymer POM‑C。
	Mold temperature	40‑90	℃	Higher mold‑temperature improves crystallization, gloss and reduces sink‑marks。
Injection parameters	Injection pressure	80‑130	MPa	Thin‑wall:120‑150 MPa；Thick‑wall:80‑120 MPa。
	Hold‑up pressure	40‑80	MPa	50‑70 % of injection pressure for shrinkage compensation。
	Back pressure	0.5‑2.0	MPa	Low back‑pressure required; high back‑pressure induces shear‑overheat degradation。
	Injection speed	Medium‑high(30‑80 mm/s), multi‑stage	mm/s	Too‑slow: flow marks; too‑fast: jetting & shear heat。
	Screw speed	30‑80	rpm	Avoid excessive rotational speed to reduce shear heat。
	Barrel residence time	＜20	min	Avoid long‑term high‑temperature retention。
Shutdown procedure	Short‑term stop	Cool barrel below 150	℃	Long‑term shutdown: fully purge barrel with PE / PP。
	Purge note	PE / PP	—	Keep barrel‑screw assembly clean。
Post‑treatment	Annealing(optional)	—	—	Relieve residual stress for high‑precision parts working under non‑ambient service condition。
