What is Automotive Casting?
Automotive casting is the process of manufacturing metal components for vehicles using investment casting techniques. The method involves pouring molten metal into a mold, allowing it to solidify, and extracting the final component with high dimensional accuracy and superior surface finish.
Investment casting is the preferred method over sand casting, pressure die casting (PDC), and shell moulding due to its:
- High precision and intricate detailing
- Superior surface finish (reducing post-machining requirements)
- Ability to produce complex geometries and thin-walled components
- Minimal material wastage and cost-effectiveness
