Composite Tools

Molds - RTM

RTM/VARTM COMPRESSION MOLDS

With over 30 years of experience in manufacturing complex injection mold systems, Westminster Tool’s engineers understand the importance of controlling thermal inputs to the repeatability and optimization of production processes. These same principles of thermal control apply to composite tools and the molding processes. Westminster Tool has been successful in applying these principles to a variety of different composite mold types to increase process repeatability, reduce cycle time, and significantly decrease manufacturing equipment footprint.

Westminster Tool has collaborated with our customers’ to produce innovative mold systems for the following composite manufacturing methods:

  • Resin Transfer Molding (RTM)
  • Vacuum Assisted Resin Transfer Molding (VARTM)
  • Compression Molding

PRECISION MACHINING FOR COMPOSITE TOOLS

Westminster Tool has successfully applied our dynamic approach to precision machining of complex details for injection and composite tools to our customers’ other tooling needs. Increasingly, this has included tooling used in preforming fabrics and fibers for composite part manufacture. Whether our customers require traditional in-oven, vacuum preform tooling or a customized out-of-oven solution, Westminster Tool has the design and manufacturing experience to provide preform tooling that meets our customers’ most demanding requirements.

 

Our Preform Tooling Expertise Includes:

  • Complex, build to print tool manufacture
  • Large preform tool systems with numerous details
  • Integrating preform tool systems with automation
  • Tool manufacture using a variety of materials, including anodized aluminum
  • Tool design consulting services
