Dense Aluminum Castings for Pressure Applications
We produce aluminum alloy precision castings for applications that need good density and dimensional control. Our primary processes are permanent mold casting and low-pressure casting. These processes give better dimensional accuracy and denser material structure than sand casting. They are suitable for hydraulic housings, pump housings, and other aluminum parts that need pressure containment. Our materials are A356 and A357. These aluminum-silicon-magnesium alloys have good overall properties. After T6 heat treatment, the strength increases significantly.

Dimensional Control and Surface Finish
The dimensional tolerance is CT5 to CT7. The surface roughness is Ra6.3 to 12.5 micrometers. The mechanical properties after T6 treatment are tensile strength at least 220 MPa, yield strength at least 140 MPa, and elongation at least 3 percent. We perform UT Level 2 inspection to control pores and shrinkage. The castings are dense and seal well. They can withstand working pressure. Aluminum has a big advantage in weight reduction. The density is about one-third of steel. This helps reduce the total weight of your equipment.

In-House Heat Treatment
Our casting shop has a 15-ton arc furnace for aluminum melting. We also have smaller melting furnaces for medium and small batches. The permanent mold and low-pressure casting molds are designed in-house or made by our partners. Our heat treatment shop has car-bottom resistance furnaces. We do solid solution and aging treatment. The T6 treatment significantly increases the strength. Our testing lab has a spectrometer for chemistry analysis, a universal testing machine for mechanical testing, and an ultrasonic flaw detector for internal defect inspection.
