About Plymouth Foundry Inc.

Plymouth Foundry, Inc. is a family-owned gray iron and ductile iron jobbing foundry, targeting short to medium length runs. We are located in the heart of the Midwest in Plymouth, Indiana. We serve a wide spectrum of customers throughout the United States. Under management by direct descendents of the original founders, we are motivated to provide service commiserate with family pride. The company has roots back to 1929 and has continued its operations in the same location ever since. Stable, family-owned and managed, service-oriented and convenient location, are words describing our heritage.

We are committed to providing great service and quality products in our quest to surpass our customers' expectations in both casting and machining. We are customer-oriented. We pledge to achieve conformance to the requirements and expectations of our customers, and the applicable statutory and regulatory requirements. As an ISO 9001:2000 certified company, we are committed to continuous quality improvement. Our ability to machine castings here saves you added transportation costs and potential nonconformance issues systemic with having separate facilities perform those functions.

Every year we consider what capital improvements may be required to achieve our goal of providing great service and quality products. Our objective is to be a leader in the implementation of technology for our industry. We were among the first in our industry to install shop floor data collection, on floor shop card controls, and most recently 3D printing capabilities. Technology and dedicated well qualified employees allow us to provide rapid prototype turnaround from your design to sample castings as well as production parts cast and machined to your specifications.
