Structural foam moulding (also known as low-pressure 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.

Structural foam moulding
In Structural foam moulding, the foam injected into the mould continues expanding, as long as the plastic has not solidified. This technique ensures that the internal pressure on the cooling plastic is evenly distributed, reducing internal tension inside the finished product.
Advantages of structural foam moulding:
- Reduced risk of deformation
- Thicker walls become an option
- More options for walls with different thicknesses
- Greater freedom in terms of design compared with high-pressure injection moulding
Common product wall thicknesses:
- 3 to 8 mm
Points to consider with structural foam moulding:
- ‘Foamed’ finish
- May be necessary to paint the product
What does structural foam moulding cost?
Every injection-moulded plastic product is unique. To answer the question of what structural foam moulding would cost, HSV-TMP takes various factors into account to come up with a cost estimate, such as:
- Product specifications
- Mould dimensions
- Type of plastic and any additives
- Technique and combination of techniques
- Finishing, assembly and logistical preferences

- Hybrid, combination injection moulding & particle foam engineering
Types of thermoplastics
There are various thermoplastics available that are used for thermoplastic injection moulding of large plastic products, housings or shaped components. You can find more information about these plastics here.
Sustainable thermoplastic injection moulding
For sustainable thermoplastic injection moulding of your plastic products, shaped components, housings and other plastic parts, you’ve come to the right place. HSV-TMP finds the most sustainable solution for you, in terms of minimising material use, optimising matrix investments, and finding assembly and logistical solutions that will save you time and money. We use sustainable energy, generated from solar collectors, for the production and assembly of your product, and you can opt to use recyclate in the production process. More about CSR at HSV-TMP.
