Get Injection Molded OEM Parts for Your Business
Located in Hartland WI, Retlaw Industries has been a leading supplier of precision plastic components for industries throughout Wisconsin for decades. When it comes to quality design and production of tight tolerances in mold making and injection-molded parts, Retlaw’s expertise is unsurpassed.
We will work with you to produce original plastic components for your consumer products, offering the following services:
- Design – Our engineers have the product design expertise to ensure your thermoplastic OEM parts will operate correctly before they are put into production. We incorporate the latest design software to test each model and will produce rapid 3D prototypes so you can see your design well before it’s in production.
- Tooling/Machining – Retlaw’s machinists are masters of their craft and will employ a wide array of tools to ensure each mold produces the highest precision plastics possible. Retlaw uses Wire and Sinker EDM, CNC turning centers, and a variety of milling machines to produce press molded and injection molded plastics for a range of industries.
- Injection Molding – Our thermoplastic injection molding process is done in the same facility as our tooling and design centers. Retlaw's injection machines range from 45 to 720 tons and are capable of producing plastic molds in a variety of depths and configurations.
- Assembly – If your OEM part is comprised of more than one piece, our assemblers will work to send you a completed component. Our assembly room is right next to the molding center, so there is no need to worry about unnecessary logistics sending your part out of state for assembly, only to be shipped back to your Wisconsin company.
- Quality Control – At Retlaw, quality control isn’t just another department, it’s a philosophy injected into all of our resin-based plastic products. No product leaves any department until it is perfect; but just to be sure, we employ quality control experts to help live up to our ISO 9001:2015 certification.
