GW Plastics has always excelled at Design for Manufacturability (DFM) support. We are a strong believer that early supplier involvement is critical to successful new product introductions. The goal of GW/PD™ (Product Development) is to reduce customer product cost and time-to-market.

GW/PT™- GW Precision Tooling

Building precision tooling requires advanced technological capabilities, a zero defect culture, and the highest levels of design integrity.

GW Plastics internal mold design-and-build capabilities ensure that customer applications will perform as designed not only at launch, but consistently throughout the life of the program.

With the state-of-the-art tool building capabilities in both our North American and China operations, maximum efficiency and quality is achieved by using highly standardized design practices, highly automated work cells, and global cross-training.

GW Plastics is one of the few injection molding companies to offer the significant benefits of in-house mold building on a global scale, featuring:

  • Zero-defect tool DFM philosophy
  • Quick turn-around prototype support
  • Single cavity bridge tooling for production launch
  • High cavitation tooling for volume production
