You don’t have to know all these shit, just tell your ideas to Dewin team

Possible weight of the part	0.015 ~ 12 kgs
Possible size of the part	4 mm ~ 650 mm
Possible wall thickness	0.3 mm ~ 13 mm
Tolerances by casting	± 0.1 mm
Tolerances by post machining	0.02 mm
Minimum order quantity	500 kgs

High efficiency, semi-automatic production, use robot arms for material loading and workblank demoulding.
Good at making thin wall and complex structural parts. Min wall thickness 0.3 mm for Zinc alloy parts, 0.5 mm for Aluminum alloy parts, min casting hole diameter 0.7 mm.
High precision on dimensions, casting tolerance could reach CT3 ~ CT6 class, ±0.05 mm, please refer to below table for details.
Good surface roughness, Ra 0.8 ~ 3.2 μm.
Good dimension consistency, sizes are provided by tooling
Available for insert molding, combine steel part with aluminum part by only one time casting to save post-assembly.

Air holes in the thick wall part caused by high speed injection, need to do resin impregnation if you have requirement for air tightness.
High tooling cost compared to pure machining if the quantity is small.
