About Us

Lansing, Michigan, USA

Established 1937, IMPCO developed and introduced the first ‘automated’ crankshaft microfinishing machine in 1948 that polished main and pin bearings on an 8-cylinder automotive crankshaft.

Since then, the company, through its internal R&D department, has engaged in continuous product development to ensure its microfinishing (superfinishing) solutions improve customer product quality and functionality in every application.

The patented IMPCO Microfinishing process has always been the heart of what the company does to help its customers achieve superior part function characteristics through submicron control of surface finish and geometry of precision ground journals.

The advantages of the IMPCO microfinishing process is delivered to automotive, medical, defense, and motorsport users worldwide through its Global Sales and Service Network, with North and South America, Europe and Asia.
