Mold Takeover Service

Petersen Molding offers a "mold takeover" service. This is a service where we evaluate, improve and complete any existing plastic injection molding jobs you may have that might not meet your expectations.

We look for ways to improve the existing plastic injection molding project, and we correct the problems on that product. Then we complete the task. Only this time around, it’s done with both superior quality and efficiency saving time and money.
