Investment Casting - Capabilities

Investment Casting


Impro is capable of meeting material specifications according to ASTM, SAE, AISI, ACI, DIN, EN, ISO, and GB standards. We pour more than 100 different ferrous and non-ferrous alloys. Dimensionally and geometrically complex investment castings are produced to net shape, minimizing the need for secondary machining.
