The Airo Division was founded in 1975 for the express purpose of producing aluminum die cast compressor blades for the nuclear industry. We have since grown significantly and currently serve a variety of specialized industries. Our custom designed, 155,400-square-foot manufacturing facility provides the ideal environment for a full range of service capabilities.

In addition to the customary services offered by die casters, the Airo Division provides specialized in-house operations such as tool design and construction, impregnating, pressure testing, chromating, painting and assembly. With our technical background, experienced staff and management team, the Airo Division can become your single-source for precise aluminum die cast products.

Pace Industries Airo Division boasts of its impregnation services - a process that few die casters provide. Impregnation seals porosity in any metal casting that must be pressure tight. This treatment is applicable to iron, steel, copper, brass, bronze, aluminum and magnesium alloys. Quantities from one to several thousand pieces can be treated.

Castings used in pressure applications are usually pressure tested to determine if the casting leaks and therefore requires impregnation, or to verify that an impregnated casting has been sealed. Airo Division provides "air check" testing for low pressure applications and "hydrostatic" testing for high pressure applications. All pressure testing fixtures are designed and built in our own tool shop.

The Airo Division has installed a complete new chromating line with an overhead crane system. Chromating is a surface treatment given to die castings to increase their resistance to corrosion. This protective coating also acts as a primer or base for paint or dyes.

A considerable portion of our facility is allocated to machining and finishing. These secondary operations include trimming, deburring, vibratory finishing, milling, drilling, tapping, threading and polishing. In addition to providing customers with quality die cast products, we can also supply fully machined and assembled components, packaged according to customer requirements and specifications.

Our modern die casting machines, the core of our operation, work around the clock. These machines are capable of producing top quality castings - whether you need 100 or 100,000 parts. Our experienced operators provide hands-on control during the casting process.
