Your Cost-Effective Solution for Complex Small Parts
We manufacture precision casting machining at our factory, a service we have provided since 2009. This approach is ideal for components with complex shapes or internal cavities. We use investment casting to create a shape close to the final part, reducing material waste and machining time. These parts are commonly used in pumps, valves, gearboxes, and food machinery. Holding the IATF16949 certification ensures that quality is always our top priority.
Casting Quality and CNC Precision Working Together
We work with high-quality casting steels, such as carbon steel WCB and low-alloy steel ZG270-500. The casting process produces a smooth surface finish of Ra 6.3 μm and maintains tight tolerances of CT6 to CT7, allowing us to cast complex flow paths and thin walls. After casting, we perform heat treatments, such as normalizing or annealing, to relieve stress and make the metal easier to machine. We also conduct non-destructive testing-including X-ray and magnetic particle inspection-to detect hidden defects.

Our Full Service from Casting to Finished Part
Final machining is performed on vertical or horizontal machining centers, focusing on key areas. Sealing surfaces are machined flat and smooth, bearing holes are bored to H7 tolerance, and standard pipe threads such as NPT or G threads are cut. Every part is inspected before shipping. We provide transparent pricing, regular production updates, and respond to any inquiries within 24 hours. Our goal is to be your reliable partner for complex cast parts.
