Highly-engineered products

About Impro Aerospace

Impro Aerospace is a full-service precision casting and precision machining component manufacturer. Over the past decade, Impro Aerospace has been supplying high quality products to renowned global OEM customers in the aerospace, medical and energy markets.

Castings are poured via investment casting, permanent mold casting, and shell mold casting processes from a few ounces up to 100 pounds. Materials include aluminum, super alloy, stainless steel, and low alloy steel. Custom ultra-precision 5-axis and 4-axis CNC milling services are available for precision machining parts out of bar stock, plates, and billets, whether for high, medium, or low volumes.

Being ISO 9001, AS9100 and ISO 13485 certified, we ensure manufacturing processes and our products conform to the highest quality standards. In-house NADCAP certified special processes and Lab/NDT testing not only ensure high quality but also reduce product lead time.

Impro’s in-house tooling design/manufacturing capabilities and rapid prototype facilities are highly valued by customers who seek quick turnaround on new product development, robust process control, and expedient delivery.

Strategy

Our goal is to become one of the top players for supplying medium to high complexity castings and precision machining products to the aerospace, energy and medical industries. We will continue to expand our customer base and deepen relationships with leading global OEMs whose equipment and systems demand high quality and mission-critical components as well as global services for engineering support and supply chain management.

Impro Capabilities

Investment Casting

robust process capabilities

Permanent Mold Casting

Low-Pressure Permanent Mold

gravity and rotary pouring

We primarily manufacture castings for aerospace, energy and medical application via the investment casting process. In addition, we offer permanent mold, low-pressure permanent mold, and shell mold casting processes to meet the all-around needs of our customers to provide a total solution. The typical aerospace casting requires robust process capabilities to ensure consistency of product quality and ability to hold extremely tight tolerances….Read More

Permanent mold casting is a metal casting process that uses reusable molds (“permanent molds”) usually made from metal. Our process uses gravity and rotary pouring. At Impro, we cast aluminum using the permanent mold casting process with casting sizes up to 16 inches in diameter or length and weighing up to 35 pounds. Typical products that we produce using this process include gear housings, pipe fittings, adapter ports, fuel injection housings, pump housing, front housing, pump covers, and flange mounting….

Shell mold casting is an expendable mold casting process that uses a resin covered sand to form the mold. It is used for small to medium parts that require high dimensional accuracy. The molten metal is poured into an expendable mold, which is typically a thin-walled shell. The pattern, a metal piece in the shape of the desired part, is reused to form multiple shell molds…..Read More

Impro’s unique capabilities are developed to meet the most demanding application requirements in the aerospace, energy and medical industries. We produce high precision and complex machined parts for customers using input material such as bar stock, plates, ingots, billets, and forgings. Whether machining aircraft braking system components, aircraft engine components, or hydraulic parts, which are made of super alloys, stainless steel, aluminum materials;….Read More
