Precision Investment Casting Foundry Gravity Casting for Car Spare Parts

Automotive casting parts form the structural backbone of modern vehicles, manufactured through precision sand casting, die casting, and investment casting processes. These components utilize advanced aluminum alloys, ductile iron, and magnesium to achieve optimal strength-to-weight ratios. Engineered to meet rigorous automotive standards, they enable complex geometries while ensuring durability and performance. From internal combustion engines to electric vehicle platforms, these castings provide critical solutions for weight reduction, cost efficiency, and manufacturing scalability across the automotive industry's evolving technological landscape.

Core Processing & Customization Services

Dual Casting Technologies: Investment & Gravity Casting

Our precision investment & gravity casting car spare parts (Model VEA005) are engineered with a dual-process approach, combining silica sol investment casting and gravity casting to meet diverse automotive spare part needs. Paired with high-precision CNC machining, this one-stop solution produces non-standard vehicle accessories made from premium materials, including casting alloy tool steel (CS-2, CrWMn), ductile iron, and magnesium alloys. We accommodate parts weighing 1g to 30kg, with blind hole depth up to 30mm (diameter 10mm). The casting tolerance reaches CT4-CT7, and surface roughness is controlled at Ra1.6-Ra6.3, ensuring perfect fit for car spare part replacement and upgrade.

Customized Solutions for Automotive Needs

We offer fully tailored services, from mold production to surface treatment, based on client specifications. Our heat treatment processes (normalizing, aging) enhance part hardness and durability, while surface finishing options (black coating, mirror polish) meet aesthetic and functional requirements. Our design team supports multiple software platforms (AutoCAD, Solidworks) and accepts file formats like XT, JPEG, and JPG, enabling seamless collaboration for custom car spare part development.

Core Advantages & Application Scenarios

Key Competitive Advantages

Exceptional Lightweight Performance: Aluminum and magnesium alloy castings reduce vehicle mass by 30-50% compared to traditional steel parts, directly improving fuel efficiency and EV driving range while maintaining impact resistance.

High Design Versatility: The casting process allows integration of complex structures (e.g., electromagnetic shielding layers, thermal management channels) into single components, reducing assembly steps and failure risks.

Scalable Cost Efficiency: Near-net-shape manufacturing minimizes material waste and machining time, making our parts ideal for large-scale production of car spare parts with stable quality.

Targeted Application Scenarios

Our products cater to three core automotive markets: first, mainstream passenger vehicles, supplying high-volume engine components, wheel hubs, and subframes; second, heavy-duty commercial trucks, offering durable axle parts, brake system components, and powertrain housings that resist long-term wear; third, new energy vehicles, providing specialized castings for battery enclosures, motor housings, and power electronics mounts, ensuring thermal stability and structural integrity for EV platforms.
