Main Qualities of Plastic Parts Built Through Structural Foam

Compared to traditional molding methods, plastic parts manufactured through structural foam injection have some additional and unique features that you should know about.

Main Qualities of Plastic Parts Built Through Structural Foam

Plastic parts are now being used in almost every field, but do you know how they are built? Today, injection molding is the simplest and the most suitable method for manufacturing plastic parts. In this blog, we are discussing the main attributes of products built by Structural Foam Molding Companies as it is a different method from traditional molding methods.

To understand how Structural Foam Molding is different from normal injection molding methods, you need to understand the whole process. We have here described the foam injection molding process along with its benefits so that you understand why it is very popular nowadays.

The Process

If you are already aware of traditional injection molding methods, you can easily understand the structural foam molding process. It is a process, very similar to normal injection molding methods, but with one difference. An inert gas injected into the molds along with molten plastic is the reason why structural foam molding is different. This gas acts as a chemical blowing agent and consequently, the core of the end products remains with a foam-like structure. No, it doesn't affect the strength of the final products much because the outer walls remain thick and solid.

What are the qualities of a product that has been built by a reliable Structural Foam Molding Company? If you use high-quality molds and the whole process remains steady and error-free, then the finished products will certainly have the following qualities.

  • Due to the foam-like structure of the core, end products will have high strength-to-weight and stiffness-to-weight ratios. These products are basically used in such fields where strong and lightweight plastic parts are needed.
     
  • Plastic parts with a foam-like core structure generally have sound deadening and electrical/thermal insulating properties. This makes them suitable for several electrical appliances.
     
  • Structural foam molding allows you to build plastic parts with a consistent surface finish.
     
  • The finished products have a very good impact-resistant ability due to the low-pressure used for injection molding.
