- Structural foam molding is a modification of the injection molding process.

- Any injection moldable plastic can be used in the structural foam molding process.

- Many large parts require thicker walls than standard injection molding can produce.

- Structural foam molding allows for the injection molding of such parts through the addition of a foaming agent.

- As the plastic fills the mold, the wall of the part solidifies against the cold mold wall. A thin layer of plastic solidifies along the mold wall. This thin layer forms a skin structure over the foamed inner core. The thin outer (solid) wall is supported by the interior cellular foam structure.

- This process can be used on many different sized parts, small to large, to produce a stronger, and potentially longer lasting part.
