Frequently Asked Questions About Investment Casting for Industrial Applications


We support custom investment casting and machining solutions for a wide range of industries, including pump & valve, industrial machinery, transportation, petrochemical & marine, medical equipment, hardware & architectural, and power engineering & instrumentation. Below are some frequently asked questions about our materials, processes, tolerances, and production support.

1. What industries do you support for custom investment casting?

We provide custom investment casting and CNC machining solutions for a wide range of industries, including pump and valve systems, industrial machinery, transportation equipment, petrochemical and marine applications, medical equipment, hardware and architectural components, and power engineering and instrumentation parts. Our team can recommend suitable manufacturing routes based on the structure, material, tolerance, and functional requirements of each application.
2. What materials are available for different industrial casting applications?

We work with a range of materials for different service environments, including stainless steel, carbon steel, alloy steel, and duplex stainless steel. Material selection depends on the application requirements such as corrosion resistance, strength, wear resistance, pressure performance, and dimensional stability. For example, stainless steel is commonly used for pump, valve, medical, and marine components, while carbon steel and alloy steel are often selected for machinery, structural, and engineering parts.
3. Is investment casting suitable for complex industrial components?

Yes. Investment casting is especially suitable for complex metal parts with intricate geometries, near-net-shape structures, and detailed surface requirements. It is widely used for components such as valve bodies, pump housings, impellers, brackets, connectors, and equipment fittings. Compared with conventional machining from solid stock, investment casting can help reduce material waste, improve shape consistency, and lower overall production cost for suitable parts.
4. Do you provide both casting and CNC machining in one service?

Yes. We provide one-stop support from tooling and investment casting to CNC machining, surface treatment, and inspection. For many industrial applications, castings still require secondary machining on sealing faces, threaded holes, datum surfaces, or critical assembly areas. Combining casting and machining in one production flow helps improve dimensional consistency, communication efficiency, and delivery control.
5. Can you produce prototype samples or low-volume custom parts?

Yes. We support prototype development, sample production, and low- to medium-volume custom manufacturing based on project needs. For new parts, we can review drawings or samples first and then recommend a suitable method for tooling, casting, and machining. This helps customers verify structure, dimensions, and application fit before moving to larger production quantities.
6. How do you control quality for industrial casting parts?

Quality control is carried out throughout the production process, from raw material verification and tooling review to dimensional inspection and final quality checks. Inspection methods may include visual inspection, dimensional measurement, and other checks based on part requirements. For custom industrial components, controlling key dimensions, machining areas, and surface quality is essential to ensure assembly performance and product consistency.
