Manufacturing big things in a small town.
PTM is a Minnesota-based contract manufacturer providing plastic injection molding, sheet metal fabrication, tooling, machining, assembly, and shipping—all under one roof. If you’re looking for a supplier who can take a part from concept to steady production (and stay responsive when changes happen), you’re in the right place.
PTM has produced customer-specific OEM component parts for decades, with a focus on responsive support, reliable production, and consistent quality. We’ve evolved into a contract manufacturer with multiple capabilities so customers can reduce supplier handoffs and move faster.
With a vision toward customer service and quality, PTM was founded in 1970 by Wendell Zwart. Today the vision continues, as PTM is a fully functional contract manufacturing facility, owned and operated by the same family.
PTM has grown to a 50,000 square foot facility with Plastic Injection Molding, Sheet Metal Fabrication and the support departments of Tooling/Design and Machining all under one roof. With a talented and experienced staff, PTM can take your product from concept to full production.
