About Scot Forge

Scot Forge manufactures custom metal forgings for industrial and engineered applications. Its operations in Spring Grove and Franklin Park, Illinois, and Clinton, Wisconsin combine open-die forging, seamless ring rolling and supporting manufacturing services. Common product forms include rings, hollows, shafts, hubs, bars and blanks. The company describes internally engineered hydraulic presses, hammer forging equipment and ring-rolling capabilities, supported by metallurgists and inspection staff. Engineers can involve the forging team early to discuss shape, alloy, grain flow and machining allowances. Machining services use both internal resources and outside specialists, depending on the component. Scot Forge publishes quality certificates and explains that required special-process approvals must be specified for the order. Contact its team at 800-435-6621 or use the contact page to discuss the drawing, material, quantity, testing and delivery requirements.
