Structural Foam Molding
Structural foam molding is a low-pressure injection molding process that utilizes a chemical blowing agent or nitrogen gas. Structural foam molding is an extension of the standard injection molding process, but operates under the theory of delivering a ‘short-shot’ into the mold.
Gas-Assist Injection Molding
Gas-Assisted Injection Molding is a process where an inert gas is introduced at pressure, into the polymer melt stream at the end of the polymer injection phase. Preproduction Plastics Inc. offers customers molding options on machines ranging from 100 ton to 1100 ton. Their 45,000sq/ft. facility has 85 employees, running three shifts on eleven molding machines giving them incredible capacity to process orders with fast turnaround times. They constantly monitor our production facility in Real Time® with our IQMS ERP system.
PPI performs secondary operations during and after production to maximize our part processing. Their new mold qualification procedures allow them to ideally test new molds through a
rigorous three step process. PPI completes these steps ensuring exceptional quality and repeatability for all future production runs.

Oh my God, this is what I am looking for a few years. Thank you for uploading this video.

[@partgurus]

You're welcome

Can you add fibers to increase structural strength? Also do you have any problems with warpage of thin walled structures?

[@ShenzhenJinsunwayMouldCoLtd]

So, is structural foam moulding another meaning og gas assisted injection moulding?

[@welshsteve2009]

Just curious, how does gas counter pressure improve the surface quality of the part?
I understand that the mould is pressurised before injection but don't quite understand what effect this has.

[@romainnaivin527]

Hi Stephen. I guess that during expansion, the gas released pushes the material flow through the walls of the mould. The result is to obtain the same surface quality than the mould himself. That's similar if you add a few chemical blowing agent in your melt in a standard plastic injection process. Romain
