Drawing/Manual

Feature

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.

Weakness

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.
