Compressor wheels / impellers for turbochargers

UACJ, the leading company for compressor wheels

The demand for turbochargers has increased in recent years in response to the need for lower fuel consumption targets following Europe’s stricter emission regulations and the downsizing of engine displacement.
Having established high-accuracy master mold production technology and low-pressure casting technology using plaster molds, UACJ Foundry & Forging manufactures precise cast aluminum compressor wheels of the highest quality in the world.

Moreover, to supply compressor wheels worldwide, it has completed a production system consisting of UACJ Foundry & Forging’s domestic factory and the overseas mass-production plant of UACJ Foundry & Forging (Vietnam).

Low-pressure casting method
In the low-pressure casting method, gas at a low pressure is applied to molten aluminum to push it into a specific product mold. As this technique suppresses interior defects caused by the entrainment of aluminum oxide or other reasons during casting, it ensures stable production of high-quality aluminum castings with superior strength, durability and dimensional precision.
