Injection Mold Systems

Design Injection Mold


At Westminster Tool, we pride ourselves on being able to meet the most challenging customer requirements. As a result, we’ve built a versatile technical design team that consists of plastic, mechanical, tooling, and manufacturing engineers. Whether our customer requires a complete mold design, design for manufacturing, material selection, or reverse engineering services our experienced design team is able to support our customers’ unique challenges.

Solutions include:

  • Improved product speed to market
  • Data-driven gate and cooling advancements using Moldex3D
  • Comprehensive risk analysis and mitigation
  • Integrated quality control plans and fixturing


Westminster Tool is a leader in manufacturing injection mold systems. In addition to expanding our service offerings to include pre and post manufacturing services, we focus on the importance of building a high quality injection mold that will provide in-spec, dimensionally stable parts shot after shot.

Our dedicated employees are passionate about improving our manufacturing processes to incorporate the latest technology and innovation in order to deliver value to our customers. This is demonstrated by Westminster Tool’s commitment to the following:

  • Integration of H13 Additive
  • Automation Utilization
  • Palletization
