Custom Carbon Casting with Investment Casting

This product is a custom carbon steel precision casting manufactured via the investment casting (lost-wax) process, designed to meet the high-precision requirements of complex structural components in industrial, automotive, and fluid control applications.

In terms of craftsmanship, investment casting enables the creation of intricate geometries—including multi-directional holes, special-shaped bosses, and internal cavities—that are difficult to achieve through traditional forging or machining. The one-piece molding eliminates the need for additional assembly, significantly enhancing the structural integrity and mechanical properties of the part. Made from high-quality carbon steel, the castings feature a uniform and refined microstructure after precision casting, delivering excellent tensile strength and fatigue resistance to withstand harsh operating conditions such as high pressure and high temperatures.

Regarding precision and surface finish, the dimensional tolerance of the castings can be controlled within ±0.1mm, and the surface roughness ranges from Ra3.2 to Ra6.3μm. This reduces the allowance for subsequent machining, effectively lowering production costs. We support full customization, allowing adjustments to material grades, dimensional specifications, and surface treatments (such as passivation, sandblasting, and machining) according to client drawings. The solution caters to both small-batch prototyping and large-volume production, offering an economical one-stop service from design optimization to final product delivery.

Backed by stable process control and a comprehensive inspection system, all products undergo mechanical property testing and non-destructive testing to ensure compliance with industry standards and personalized customer requirements.
