With extensive experience across a wide range of industries—including medical, consumer products, lawn and garden, agriculture, electrical, and appliances—we’re equipped to handle complex projects with precision. By combining expert design support with advanced mold tooling, fixturing, high-speed machining, and EDM technology, we deliver high-quality molds tailored to meet the exact needs of each application.

Plastic Part Designarrow

Plastic Part Design

Drawing from our years of experience in the mold making industry, we are able to convert your ideas, sketches, or drawings into 3D designs suitable for molding. A good part design can provide returns in lower tooling costs, lower costs per piece, and a higher quality end product.

Molds

We mainly produce steel molds and are familiar with the special needs required to make any specialty mold. The complex geometry and tight tolerances combined with the need to eliminate flash along parting lines creates some of the greatest challenges to us as mold builders.

Production Moldsarrow

Production Molds

We manufacture production molds for a wide range of industries, including medical, electronics, small engine, and consumer products. Our capabilities include all mold types, MUD inserts, self-contained, three-plate, and stripper plate, in materials such as P20, S7, H13, stainless steel, MoldMAX, aluminum, and Ampco. We offer multiple gating methods to meet customer needs, including tab, tunnel, hot sprue bushing, valve gate, and multi-drop hot manifolds. Our experience includes multi-cavity, family molds, unscrewing molds, interchangeable cores/cavities, and multi-top or bottom half designs. Every project is approached with a focus on delivering the best quality and value through tailored solutions that match the unique application requirements of each customer.

Prototype Moldsarrow

Prototype Molds

We provide prototype molds for customers at their request. Materials for mold construction are either steel or aluminum. Because of the unique nature of prototype molds, the delivery, design, and any special functions or limitations are outlined at the beginning of the project.

Production Assemblyarrow

Production Assembly

We provide value-added services designed to streamline your manufacturing processes and reduce overall costs, empowering you to achieve greater efficiency and quality.

Graphite Electrode Machiningarrow

Graphite Electrode Machining

We provide custom graphite electrode design and milling. We use either Surfcam or WorkNC to calculate tool paths from the CAD data supplied by the customer. The electrodes are then cut on either our two graphite mills. Both graphite mills are setup to handle both the 3R Macro system for pallets and the 3R Micro system with 20mm stems. Graphite choice is based upon the application or customer request.

Custom Machiningarrow

Custom Machining

We provide value-added services designed to streamline your manufacturing processes and reduce overall costs, empowering you to achieve greater efficiency and quality.We also offer custom machining on an hourly or job basis. We are able to offer 4 axis wire EDM, plunge (sinker) EDM, and high speed machining services. Our lineup or Makino, OKK, GE Fanuc, and Hurco equipment is sized to handle almost any job large or small.

“We’ve worked with Prairie Tool for many years on countless projects, and their commitment to delivering high-quality molds has been outstanding. Their team consistently meets our needs, and we appreciate their collaborative approach to helping us move into production efficiently. We highly recommend them to anyone looking for a trusted manufacturing partner.”
