Global Sourcing

We deliver the best of both worlds – the high quality of domestic engineering and the lower cost of tooling overseas. We have established excellent relationships with plastic injection mold building facilities in China. We have proven processes that develop consistent high quality results. At all times, we have resources in China providing oversight and supervision for our projects. Our engineers are in China several times a year as needed. We have domestic facilities in Ohio and Minnesota to make any mold adjustments required.

Quality When Cosmetics and Volume are Important

Production systems in the electronics industry are modern and highly efficient. Our commitment to customer-centered continuous improvement, industry best practices, and emerging manufacturing technologies, ensures our customers receive only the highest quality plastic injection molding tools – tools that will hold up to today’s high volume production requirements.




Over Twenty Years of Electronics Tooling Experience

“It took us about five years to get our legs into the electronics injection molding business. No doubt, learning to achieve the extremely high degree of tolerances required by this industry was challenging. Together, with our customers, we learned how to deliver the best tools possible for this leading-edge industry. We are still learning today. The relationships we build along the way are so rewarding, we truly enjoy developing innovative solutions for our customers’ molding requirements.”
