Being a form of low-pressure injection molding, structural foam molding process utilizes mostly thermoplastics so as to mold a rigid product with higher stiffness-to-weight ratios and thicker walls in compare to that of the standard injection molded product. In this process, a chemical or a physical blowing agent is blended with the resin. Then the resin is added into the cavity while ensuring that it is not packed out or completely filled as the blowing agent expands to push the resin to the edge of the cavity. When the structure is cooled, internal shrinkage takes up because of the internal pressure of the foaming action.

Structural foam Molding is a widely used technique because it offers a wide range of benefits ranging from economical advantage over other processes to manufacturing of the parts that can’t be easily matched by other processes. One of the key benefits is that multiple parts and tooling of any specific types of equipment can be produced at the same time. As the process utilizes low pressure, it results in warpage and low stress in the manufactured parts. Offering a wide range of design flexibility, this technique helps you manufacture simple as well as complicated parts easily and cost-effectively. The Structural foam Molding technique is used especially when multiple, “family” parts of a particular product are to be made. The numerous parts can be molded all together on the same machine, thus reducing the overall cost.
