OEM Foundry Investment Lost Wax Precision Casting Car Parts

Vehicle casting parts are precision-manufactured components that form the structural and functional foundation of modern automobiles. Utilizing advanced casting techniques such as high-pressure die casting and investment casting, these parts are produced from lightweight yet durable materials like aluminum alloys, magnesium, and ductile iron. Engineered to meet stringent automotive standards, they deliver optimal strength-to-weight ratios while enabling complex designs for improved vehicle performance, fuel efficiency, and safety across passenger cars, commercial vehicles, and electric mobility solutions.

Core Processing & Customization Services

Silica Sol Investment Casting Core Process

Our OEM lost wax precision casting car parts (Model VEA016) adopt top-tier silica sol investment casting combined with high-precision CNC machining, delivering non-standard vehicle accessories that meet strict automotive industry demands. The process supports a wide range of materials, including austenitic stainless steel (201, 304, 316L), hardened stainless steel (17-4PH, 410), alloy cast steel (4140, 8620), and carbon steel (1020, 1045). We handle parts with a weight range of 1g to 30kg, achieving casting tolerance of CT4-CT7 per GBT6414-1999 and VDG Merkblad P690 standards. The minimum casting thickness reaches 2mm, with 1mm available in micro-regions, ensuring compatibility with complex car component designs.

Comprehensive Secondary Operations & Customization

Beyond casting, we provide one-stop services covering turning, milling, drilling, threading and professional heat treatment (annealing, hardening, carburizing). Surface finishing options include black oxide, mirror polish, and anti-pollution flashover coating, tailored to client requirements. Our team utilizes advanced design software (Pro-E, UG, Solidworks) and accepts diverse file formats (IGS, STP, PDF), enabling full customization for unique vehicle part designs.

Core Advantages & Application Scenarios

Product Advantages

Lightweight & Durable Design: By using aluminum and magnesium alloys, our casting parts reduce vehicle weight significantly, boosting fuel efficiency and extending EV battery range without sacrificing structural strength.

Cost-Effective Production: Near-net-shape casting minimizes material waste and secondary machining, cutting manufacturing costs for high-volume automotive applications.

Superior Design Flexibility: The process integrates complex features like cooling channels and mounting points into single-piece castings, simplifying assembly and improving overall vehicle performance.

Versatile Application Scenarios

Our car casting parts serve three key automotive segments: first, passenger vehicles, providing engine blocks, wheel hubs, and suspension components that balance performance and cost; second, heavy-duty trucks, supplying durable axles, brake system parts, and engine components to withstand extreme loads; third, high-performance & luxury cars, delivering precision-cast turbocharger housings and structural reinforcements that meet stringent quality standards.

Quality Assurance

Rigorous Quality Control

We maintain strict quality checks throughout production, from raw material inspection to final product testing. Surface roughness is controlled within Ra1.6-Ra6.3, and casting radii comply with round radius ≥0.3mm and internal fillet radius ≥0.5mm requirements. All processes adhere to international standards (ASTM, DIN, JIS, ISO) to ensure consistency and reliability.

Authoritative Certifications

Our factory holds ISO9001:2015 and SGS certifications, validating our commitment to quality management systems. These certifications guarantee that every car casting part meets global automotive industry benchmarks, providing clients with trustworthy products.
