Our Processes

Two Core Casting Capabilities

We specialize in low-pressure and gravity die casting — two proven processes for producing dense, high-precision aluminum parts at scale.

Low-Pressure Die Casting

Molten aluminum fills the mold upward under 0.1–1.0 bar pressure, minimizing turbulence and air entrapment. Best for complex thin-wall parts with strict air-tightness requirements.

Gravity Die Casting

Metal pours by gravity into permanent molds. Lower tooling cost, suitable for medium-batch production, complex inner cavities, and simply structured large parts with long mold service life.

Low tooling cost Long mold life Complex cores Medium batch

Custom Mold Design

In-house mold engineering from 2D drawings, 3D files, or physical samples. DFM analysis provided before tooling begins to avoid costly revisions.
