OEM Auto Parts Metal Machining Housing Sand Casting Grey and Ductile Cast Iron Foundry

In the automotive manufacturing sector, precision-cast metal housings form the structural foundation for numerous vehicle systems. Our specialized foundry provides OEM auto parts manufacturers with comprehensive sand casting services for both grey and ductile iron housings, complemented by complete machining capabilities. This integrated approach delivers finished components ready for immediate assembly in braking, transmission, steering, and engine systems, meeting the automotive industry's stringent requirements for quality, consistency, and performance.

Material Excellence and Performance Characteristics
We utilize high-grade grey iron (G2500-G3500) and ductile iron (GGG40-GGG60) specifically engineered for automotive applications. Our grey iron housings provide excellent vibration damping capacity – approximately 6-10 times greater than steel – with tensile strength of 250-350 MPa, making them ideal for reducing noise, vibration, and harshness in vehicle systems. Ductile iron components deliver superior mechanical properties including 400-600 MPa tensile strength, exceptional impact resistance (Charpy values of 12-20 J), and elongation of 6-18%, providing the durability required for safety-critical applications. Both materials demonstrate outstanding wear resistance and maintain dimensional stability across automotive operating temperatures from -40°C to 200°C.

Integrated Sand Casting and Machining Process
Our manufacturing employs advanced green sand casting with automated molding lines that maintain dimensional consistency for high-volume automotive production. The process begins with simulation-optimized pattern equipment designed to achieve optimal solidification characteristics specific to automotive housing geometries. Controlled pouring parameters and real-time thermal monitoring ensure sound castings with minimal shrinkage porosity in critical areas. Each housing undergoes precision machining on dedicated CNC transfer lines and machining centers, maintaining bore tolerances within ±0.0008 inches and surface flatness within 0.001 inches per foot. The integrated process includes 100% dimensional verification, leak testing for sealed housings, and complete material certification traceable to production batches.

Comprehensive Automotive Applications
Our cast and machined housings serve critical functions across vehicle systems including transmission cases, differential carriers, brake caliper housings, power steering pump bodies, and engine bracket components. The automotive industry utilizes our grey iron castings for applications where vibration damping is prioritized, such as engine blocks and transmission cases. Ductile iron components are specified for safety-critical applications including steering knuckles, suspension components, and brake systems where impact resistance and fatigue strength are essential. Our manufacturing capabilities accommodate components ranging from 1 kg to 50 kg, with production volumes supporting both prototype development and high-volume manufacturing requirements.
