Metal injection molds, also called dies, are used to produce a vast range of injected plastic products across every industry. Other companies may sub-contract their mold construction. Papler Industry’s plastic injection molds are all manufactured in-house from our dedicated mold-build facility in Michigan. Constructing the molds is the most time-consuming phase of the injection molding process. They require precision tooling by skilled technicians. Our experienced toolmakers work alongside our engineers and inspectors throughout the construction process to ensure everything is built exactly to specification. This level of attention is required because even the smallest misstep can cause costly errors.
