Structural foam moulding - Housing for roof fan

Market: HVAC

Technique: Structural Foam Moulding

Material: PP

Particulars: 

Here you see a complex housing assembly for roof fan.

Made by Structural foam moulding (also known as low-pressure foam moulding).  With this technique it is possible to integrate functionalities and realize a stable product with different wall thicknesses.

Structual foam moulding allows some of the disadvantages of high-pressure injection moulding to be overcome. The main difference is that a chemical blowing agent is added to the plastic granules. This is activated when the plastic is heated to its melting point.
