Features of the company

Sumikin Precision Forge, inc. (SPF) is a cold forging manufacturer with thirty-four (34) years of experience.

We are engaged in manufacturing and marketing high quality cold forgings for the automotive industry as well as high-strength bolts. Our quality and environment systems are ISO 9001 and ISO 14001 registered, respectively and raw materials are carefully selected and supplied by an integrated steel mill, Sumitomo Metals (Kokura), Ltd. .

For new business, we just have started precision die designing, manufacturing and marketing.

In 1997, we founded Indiana Precision Forge, LLC. (IPF,LLC.) in Shelbyville, Indiana, USA. to manufacture and market high quality forgings for the automotive industry.
Together with IPF, LLC., SPF is now in a position to supply high quality cold forgings both in Japan and North America.

We are continuously upgrading cold forging technology to make our products near-net-shape, which enables our customers to eliminate many machining processes.
