Profile: Impro Industries USA, Inc. is a manufacturer of precision, complexity, and mission-critical components. Investment casting is a metal forming process that generally involves using a wax pattern surrounded by a ceramic shell to form a ceramic mold. Once the ceramic shell is dry, the wax is melted out, and the ceramic mold is formed. We specialize in precision machining, sand casting, and surface treatment services. Our facilities use both green sand and resin sand production lines to form molds used to produce small to large components. We are able to use a wide range of metals such as stainless steel, carbon steel, and alloy steel.
