Why pay more?

Keep It Local

You don't have to pay more for shipping from a big city mold manufacturer. We've been in the business for over 35 years and can fabricate custom molds for just about anything from fishing lures and electronic connectors to very high precision, close tolerance molds. We specialize in electrical discharge machining (EDM), repairs, mold designs, and high precision machine work.


We honestly value our customers whether you're an inventor in need of a mold design, or a manufacturer needing parts for a machine. We cordially invite you to visit our production shop in Springfield, Missouri in person where you can work directly with our local design team. Not quite sure exactly what you need? Our design experts are happy to help!
