Shanghai Heda Castings is a professional manufacturer and exporter of investment casting (lost wax casting) in China, we supply various of investment casting auto parts, for both passenger vehicles and commercial vehicle.
Investment casting, also known as lost wax casting, is a metal forming process that involves making a wax model of the part to be produced, coating it with a ceramic shell, and then heating the shell to remove the wax and harden the ceramic. Molten metal is then poured into the ceramic mold to create the final part. Investment casting is a precise and repeatable process, which makes it ideal for producing high-quality auto parts with complex geometries and tight tolerances. The use of steel and stainless steel in investment casting is particularly beneficial in the production of auto parts due to their strength and resistance to corrosion. Steel is a durable and cost-effective material that is commonly used for engine and drivetrain components, as well as for suspension and braking system parts. Stainless steel, on the other hand, is known for its high corrosion resistance, which makes it ideal for use in exhaust system components and other parts that are exposed to high heat and corrosive gases.
Some examples of auto parts that are frequently made using these techniques include:
Engine components: Steel and stainless steel investment casting is often used to produce engine
components such as cylinder heads, valve guides, valve bodies, rocker arms, and connecting rods.
Suspension components: These techniques are used to produce parts such as ball joints, control arms, and steering knuckles.
Transmission components: Steel and stainless steel investment casting is used to produce parts such as transmission cases, gears, and shift forks.
Brake components: Parts such as brake calipers and brackets are commonly made using steel or stainless steel investment casting.
Exhaust system components: Steel and stainless steel investment casting is used to produce parts such as exhaust manifolds, turbine housings and mufflers.
Fuel system components: Fuel injectors, fuel rails, and carburetor bodies.
Body and interior parts: Door handles, mirror brackets, and seat brackets.
In addition to these components, steel and stainless steel investment casting can be used to create a variety of other parts for the automotive industry, such as brackets and housings.
Steel investment casting is typically used to create parts that require high strength and durability, while stainless steel investment casting is often used for parts that require corrosion resistance and/or a high level of surface finish. In summary, investment casting is a versatile and precise metal forming process that is well-suited for the production of auto parts made from steel or stainless steel. The use of this process can result in high-quality parts with complex geometries, tight tolerances, and excellent strength and corrosion resistance.
