Key Features & Advantages
High Precision Manufacturing
Casting tolerances up to CT4–CT6 with CNC machining accuracy of ±0.03mm ensure perfect dimensional consistency and assembly fit in precision lock mechanisms.
Complex Geometry Capability
Investment casting excels at producing thin-wall sections, deep holes, undercuts, and irregular shapes that conventional machining or die casting cannot achieve cost-effectively.
Superior Surface Finish
As-cast surface roughness of Ra 0.8–1.6μm significantly reduces or eliminates costly secondary polishing operations, ideal for visible lock hardware for Custom Investment Casting Machined Lock Part.
