Closed Mold Tooling

Closed molding tooling

The quality of tooling has a big impact on the closed molding process.

Utilizing proper tooling in each closed mold method is essential to producing a part correctly. Remember to always “Design for the Process.” Use tooling designed for the specific process you are trying to use.

Tooling costs and complexity increase as the part performance requirements and the number of parts to be produced increase.

Tooling requirement's for each closed mold process varies:

  • In the Light RTM process, both an “A” side mold and “B” mold are utilized, and they must be high-quality, accurate molds, which accounts for higher start-up costs than with VIP or Reusable Bag Molding.
  • Existing molds can easily be converted for Reusable Bag Molding, and no consumables are used, so tooling costs for this process are relatively low.
  • With Vacuum Infusion, standard composite tooling can generally be used, as long as it will hold a vacuum and the flange is wide enough to seal the bag; therefore, tooling costs are lower than those of other closed mold processes.
