There are numerous benefits to selecting structural foam or gas assist molding. Structural foam molding is an excellent conversion alternative for wood, metal, concrete and fiberglass. It can also offer a significant ROI in comparison to other processes such as rotational molding, RIM, thermoforming, die cast, injection, and SMC. The result is a significant reduction in cost and vast increase in productivity. The following are the key benefits of structural foam molding:
- 20% less weight than high pressure parts
- 3-4 times more rigid than solid parts
- Substantial cost reductions
- Low mold cavity pressure allows lower cost tooling
- High stiffness-to-weight ratio
- High dimensional stability
- Capable of molding parts as thin as .156″ thick or greater
- Low warp and part stress
- Multiple molds can run simultaneously
- Functions as excellent substrate for high quality painted finish applications
- Virtually any thermoplastic can be foamed
