Winamac Coil Spring, Inc. is an innovative family owned business founded in 1948 by Walter Pesaresi. The hard work and commitment to customer satisfaction of our founder is the cornerstone of company success today as a leading manufacturer of compression, extension and torsion springs. Today the company is led by second and third generation descendants of Walter Pesaresi who proudly carry on the same dedication to our customers.  

Winamac Coil Spring, Inc. has been selected as sole or primary source by many of our customers. Several reasons for this honor are dedication to customers, total quality commitment, broad manufacturing capability with wire sizes ranging from .008" to .625", state of the art coiling and secondary equipment and most importantly, because of our greatest asset, our empowered, well-trained and highly motivated employees.

Our springs are found in a variety of products such as agricultural equipment, household appliances, lawn and garden products, railroad equipment and other industrial applications. Behind each spring is the Winamac Coil Spring, Inc. tradition of unmatched quality and customer service built over decades of commitment to our customers, regardless of company or order size.
