Investment Casting

Impro is a worldwide leader in investment casting, a process of forming metal that typically uses a wax pattern surrounded by a ceramic shell to make a ceramic mold. When the shell dries, the wax is melted away, leaving only the mold. Then the casting component is formed by pouring molten metal into the ceramic mold.

Advantages of Investment Casting

There are numerous benefits of investment casting. The process can eliminate secondary processes after casting and reduce tooling costs over several production runs. With an extensive selection of alloys to choose from, the final parts display accurate and smooth surfaces, low tolerances, and allow for lower weight with thin walls. The design flexibility has a wide range so parts can be produced in almost any size or complexity. Other methods do not provide the same tolerance levels.

Impro’s Investment Casting Capabilities

Impro is capable of meeting material specifications according to ASTM, SAE, AISI, ACI, DIN, EN, ISO, and GB standards. We have more than 100 different ferrous and non-ferrous alloys with which we cast parts using a complex design criteria. Our dimensionally and geometrically complex investment castings are produced to net shape, minimizing the need for secondary machining. Our top of the line equipment and automation process controls allow for consistent and repeatable tolerances as close as ±0.1 mm. Our castings can also be produced in a wide size range. They be as small as 10 mm long x 10 mm wide x 10 mm high and weigh as little as 0.01 kg, or as much as 1000 mm in length and weigh as much as 100 kg.
