Mold Design
Mold Design is a crucial step in the injection molding process. Once you’ve finalized your part in CAD software for fit and function, it must then be transformed into a design for molding to ensure the capture of all the specified details. In some cases, certain features of the part design may not be manufacturable via the injection molding process.
At PTI, we collaborate with you to achieve the best possible design for manufacturability. In fact, we have a FREE guide to help you with this.

Our Employees and Our Community
As we go about our day-to-day business, it’s easy to lose sight of the challenges facing our employees and our community. That’s why we at PTI provide outlets for our employees to get involved.
Our employees have the opportunity to be involved in community programs that positively impact and influence the quality of peoples’ lives. You can find them active during Manufacturing Day, walking for the American Cancer Society, participating in Little Inventors or even hosting our annual Classic Car Show. By encouraging a positive “giveback” attitude, we believe it’s creating a stronger community inside and outside of our building.
