The Structural Foam Plastic Injection Molding Process

Structural Foam Description
Structural Foam Molding is a low-pressure injection molding
process that is capable of producing very large structural parts. The molten
plastic material is injected into a mold after being mixed with a blowing agent
or high-pressure gas. This produces bubbles in the plastic causing it to foam.
The foam retains the properties of the plastic but weighs less because of
reduced density.(more)
Structural Foam Advantages
Structural foam yields parts that are thicker and sturdier than injection molding....
less injection and clamping pressures required and less stresses created ....
100% recycled materials are common feedstocks ....
multiple parts being simultaneously molded on the same machine cycle.
