What began in 1966 as a small mold shop built on one man’s dream has grown into a respected and reliable partner in precision mold manufacturing. For six decades, our company has remained grounded in the same core principles that shaped its beginning: hard work, craftsmanship, integrity, and pride in every tool we build.

At Decatur Mold Tool & Engineering, we understand that every minute a mold is down is a minute of lost production. That’s why our engineering change (ECN) and tool repair services are designed to reduce your workload and keep your production moving from the very start of a service project to the moment your tool is back in the press.

At Decatur Mold, our tooling experts build precision tools that power the plastic injection molding industry—and automation is helping us do it better than ever.
