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 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
