A force in low pressure casting

Complex geometry components, to higher standards

Defects. Porosity. Poor surface finishes. When you’re working with intricate metal parts, you can’t afford line delays caused by quality issues. You need a partner with processes that prevent costly casting problems.

At Wisconsin Aluminum Foundry (WAF), we use low pressure permanent mold casting when you need symmetrical and cylindrical designs at the highest integrity, delivering strong, more uniform castings for the automotive, medical, and recreational industries.

An industry leader in low pressure casting

From compressor bodies to generator fans to oil pans, our customers can expect better outcomes with our low pressure casting process. We combine 115+ years of engineering expertise with vertically integrated services to do casting, machining and tooling of components in house. That means more control in delivering superior quality parts.

Pressure tightness

Low pressure aluminum casting is best for applications that call for minimum porosity, helping reduce the risk of gas entrapment that can lead to parts failure.

Superior quality

In low pressure aluminum casting, slow die filling and constant pressure help avoid the formation of oxides during solidification, so you get the highest integrity castings.
