Automotive Castings
What are Automotive Castings?
Automotive castings are cast metal parts used in vehicles, primarily in systems such as engines, transmissions, chassis, and suspension. The automotive industry relies on parts and components with specific performance requirements, such as physical, chemical, and mechanical properties, for their intended use. Various casting processes are used to create these parts to achieve the necessary performance criteria, ensuring safety, efficiency, and durability.
Processes for Casting Auto Parts
Taiyuan Simis Investment Casting Co., Ltd. uses four distinct casting processes to optimize the production of various automotive components, each requiring a specific manufacturing approach to balance performance, efficiency, and value.
For intricate vehicle parts like turbocharger wheels and shifter forks, we use our advanced investment casting process, which delivers high precision, smooth finishes, and reduces the need for post-processing. Sand casting can be used for producing large, economical, and durable steel or iron components such as engine blocks. At our dedicated shell molding factory, we use shell mold casting method that offers a balance of good surface smoothness and cost-effectiveness for manufacturing small to medium sized auto castings. Finally, die casting is frequently used to support the large-scale production of lightweight aluminum structural parts and housings.
One of our strongest abilities is that we can provide guidance on clients’ designs and determine the most appropriate casting processes for meeting both performance and budget requirements.
Materials for Automotive Castings
The right material not only increases the performance and reliability of automotive components, but significantly saves unnecessary costs and time to produce. We offer expertise in casting with a selection of materials, including various grades of stainless steel, carbon steel, alloy steel, aluminum alloys, cast iron and other metal alloys based on clients’ detailed parameters. We can help decide the optimal material grade for certain specifications and performance requirements, making sure that the final castings are not only within the budget of our customers but also meet all other required needs.
OEM and Custom Automotive Castings Expertise
Taiyuan Simis is a professional investment casting manufacturer in China, with 40 years of experience in the foundry industry, specializes in producing high-quality OEM and custom automotive casting parts and components for a wide range of vehicle types, including passenger cars, light and heavy trucks, SUVs, motorcycles, ATVs, racing vehicles, heavy construction equipment vehicles, as well as classic and vintage automobiles.
We also provide castings for aftermarket auto parts and accessories, such as engine components (including engine blocks, cylinder heads, cylinder head covers, crankshafts, pistons, and connecting rods), transmission parts (including housings and shifter forks), chassis components (suspension arms, control arms, knuckles), fluid handling components (pumps and valves), performance upgrades (intake manifolds, exhaust headers), aesthetic accessories (grilles, emblems) and many more.
The above list represents common automotive casting parts we produce regularly. If you would like to discuss specialized auto castings, please contact us with your requirements.

Fully Custom Services
Our custom services deliver significant value to various clients. Aftermarket auto accessory vendors and performance parts retailers can benefit from uniquely-designed, high-performance, and custom-branded products. Custom car builders and restoration specialists can obtain essential, precisely manufactured components.
We can cast various auto parts with complex designs and unique physical and mechanical properties to match the exact requirements according to customers’ drawings and specifications.
Rigorous Quality Control
As an ISO 9001, We employ a comprehensive range of testing and inspection methods throughout the production process. Our process includes visual inspections to eliminate surface defects, dimensional verification with precision instruments like CMMs, and non-destructive testing (NDT) using radiographic (X-ray), ultrasonic, magnetic particle, and liquid penetrant inspection to identify internal flaws while maintaining casting integrity.
Finally, we perform material testing—including tensile, hardness, chemical analysis, and microstructure analysis—to confirm that material properties meet the required performance standards.
Competitive Pricing
At Taiyuan Simis, we believe that cost is a critical factor for our automotive clients. We are capable of providing competitive pricing without compromising quality. There are several reasons why our auto casting parts are extremely competitive in terms of pricing. Thanks to our efficient in-house operations including tooling, treatments and machining as well as our well-optimized production processes, we effectively manage to reduce the extra cost from outsourcing.
Combining our strategic material sourcing and high-production capabilities, we can easily manage both large and small quantities, making us even more economical and thus reduce the cost even more. Finally, we implemented lean manufacturing principles, meaning that we can effectively eliminate waste and improve efficiency throughout our operations. As a result of the mentioned factors, we are able to offer our clients very competitive prices on top of our high quality castings.
