Your Partner In Manufacturing

We Do Things Right

At Plas-Tech Tooling we are much more than a machine shop or a custom plastic injection mold supplier. We strive to be your partner in manufacturing by offering reliability that is second to none. Like many manufacturers, we offer high-quality, precision CNC parts, but it’s our ability to listen and respond to our customer’s needs that separates us from the competition. It is not uncommon for us to hear customer statements like, “You guys are the only supplier that keeps bailing us out instead of causing us problems right now.” We pride ourselves on our ability not only to provide CNC machining services, but to meet even the most difficult of customer requirements such as short lead times.

Machining & Molding Company

We are unique in our ability to provide production machining services, injection mold tool building and injection molding of production parts. With our highly-trained team, we place a significant amount of combined CNC machining experience at your disposal.

We put the customer first by offering the best solution for them.


Plas-Tech Tooling was founded by Dean and Marcia Sonquist in 1993. Dean was initially the only employee and the business was housed in their garage. Plas-Tech Tooling was started to perform injection mold building and repair. This service was not readily available to manufacturers in the Garner area. From this, it grew to include production machining services for area manufactures adding other complementary services along the way. In September of 1996 we outgrew the garage and moved to the first building of our current location in Garner, IA.

Today, Plas-Tech Tooling is a full-service machine shop and injection mold building/molding operation. We have the capacity design, build, and mold custom plastic parts from high quality injection mold tools. Additionally, we perform production machining of plastic and metal components, help guide customers through the product design process, provide rapid prototypes and utilize CAD/CAM and SOLIDWORKS. Our QA and Reverse Engineering programs are enhanced through the use of our Hexagon Metrology Master 3D Gauge.
