About Metal Union

Better Process. Better Part

Qingdao Metal Union Precision Machinery Co., Ltd. supplies custom industrial components to OEM customers worldwide. Our main capabilities include forgings, castings, CNC machined parts, and integrated forging or casting with precision machining. We also supply welded assemblies, hydraulic components, hydraulic breakers, precision rubber components, and amorphous and nanocrystalline magnetic materials.

Our strength lies in selecting the right manufacturing process for each component.

We review the application's operating conditions, material, geometry, critical tolerances, and production volume to identify a practical manufacturing route. This may involve forging, casting, CNC machining, or a combination of processes.

One of our particular strengths is cast-to-forged conversion. For suitable components, we evaluate whether forging can improve structural integrity, fatigue performance, or manufacturing efficiency.

Quality starts before production. We focus on identifying manufacturing risks early, coordinating critical process controls, and verifying finished components against agreed specifications.

Working with our manufacturing partners, we coordinate production, machining, heat treatment, and inspection to support consistent quality and reliable OEM supply.

We don't just make parts. We look for a better way to make them.
