China Investment Casting: High-Precision Metal Components for Complex Designs

Redstone Manufacturing partners with leading china investment casting foundries to deliver high-precision, near-net-shape metal components for demanding industries worldwide. Our network of ISO-certified suppliers ensures exceptional accuracy, repeatability, and surface detail, making investment casting a top choice for components with intricate geometries and tight tolerances. With Redstone, you gain the cost advantages of investment casting china combined with strict Western-quality oversight and project management.

Description of the Investment Casting Process

Investment casting—also known as lost-wax casting—is a precision process used to produce detailed metal components with excellent dimensional accuracy. It begins by creating a wax pattern of the part, which is assembled onto a tree and coated with ceramic slurry. Once the shell hardens, the wax is melted out and replaced with molten metal. After cooling, the ceramic shell is removed, revealing a highly accurate casting.

Our china investment casting factory network uses advanced process controls, including:

• Automated wax-injection systems
• Ceramic shell building lines
• Vacuum-assisted casting for high-alloy materials
• Multi-stage finishing and heat treatment
• Comprehensive dimensional and metallurgical inspection

This advanced process ensures that each part meets strict mechanical and aesthetic requirements.
