Precision Casting and Machined Components for Aerospace Industry


Aerospace components are used in extreme environmental and mission critical applications. They experience fluctuating temperatures and load stresses. Often, these components feature complex and intricate metrics that need to be extremely precise to make them function correctly. Due to their often critical roles in aerospace systems and operations, these components must offer reliable performance even when exposed to high-stress environments.

At Impro, we offer precision machining, investment casting, permanent mold and shell mold casting manufacturing technologies to produce aerospace components that meet industry standards. We also offer in-house heat treatments and surface treatments as well as a host of inspection and testing services to ensure product quality. Our additional capabilities help us to provide one-stop-shop solutions, as we provide high-quality parts at competitive costs delivered on time.

Our capabilities include:

  • CNC precision machining (4-axis and 5-axis equipment) for stainless steel, alloy steel, aluminum, superalloys, and titanium to make parts from plates, billets, bar stocks, and forgings
  • Investment casting for aluminum, low alloy steel, stainless steel, and Nickel and Cobalt-based superalloys in sizes ranging from a few ounces to 253 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/hard anodizing, chemical conversion, passivation, electoplating, stress and embrittlement relief, etching, painting and dry film
  • NDT and laboratory testing including X-ray analysis, fluorescent penetrant inspection and magnetic particle inspection

We manufacture and supply investment castings, permanent mold 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.
