Aerospace – Manufacturer of Precision Casting & Machining Components | Impro Precision


Aerospace components often feature complex and intricate metrics that need to be extremely precise to make them function correctly. Additionally, because of their often critical role in aerospace systems and operations, these components must be durable and offer reliable performance even when exposed to high-stress environments.

At Impro, we use a variety of precision machining and casting techniques to produce aerospace components that meet industry standards and customer requirements. We offer in-house heat treatment, surface treatment and a host of inspection and testing services to ensure product quality. These additional capabilities help us to provide one-stop-shop solutions, allowing us to offer high-quality parts at competitive costs delivered in a timely manner.

Our capabilities include:

  • four-axis and five-axis precision machining for materials such as bar stock, billets, forgings and plates made from aluminum, alloy steel, stainless steel, titanium, and superalloys
  • Investment casting for aluminum, low alloy steel, stainless steel, Nickel and Cobalt-based superalloys and titanium in sizes ranging from a few ounces to 100 pounds
  • Permanent mold casting for aluminum parts up to 16 inches in diameter or length and 35 pounds in weight
  • Shell mold casting for aluminum parts up to 12 inches in diameter or length and 30 pounds in weight
  • Heat treatments including vacuum gas cooling, vacuum oil cooling, aluminum alloy heat treating, gas nitriding, cold stabilization, stress-relieving and tempering and aging
  • Surface treatments, such as anodizing, chemical conversion coating, passivation, plating, stress and embrittlement relief, etching, painting and dry film application
  • NDT and laboratory testing including X-ray analysis, fluorescent penetrant inspection and magnetic particle inspection

We manufacture and supply investment castings, permanent castings, shell mold castings, and precision machined parts for aerospace applications, such as air and fuel systems, engines and engine management systems, flight control systems, hydraulic systems, auxiliary power units, and landing systems.
