If talking as of now, plastic products are now being used in so many fields. This is because of some unique characteristics of plastic, such as durability and lightweight. But do you know the process through which these plastic parts are built? It is the injection molding process in which, melted polymer is injected into a pre-designed mold. But when it comes to producing light-weighted plastic products, then Structural Foam Molding is considered to be a better alternative. In this blog, we’ll explore the key advantages of manufacturing plastic parts through Structural Foam Molding.

Let’s first understand how it is different from the conventional injection molding process. While the entire process remains the same, the only difference is that an inert gas or a chemical blowing agent is also added into the melted polymer when injecting it into the mold. As a result, the end products have a foam-like structure, which is why they are not as heavy as the plastic parts built through conventional injection molding methods. So, Structural Foam Molding is certainly an ideal choice if you want to build lightweight plastic parts.

Without wasting much time, let’s now have a look at the most significant characteristic of structural foam molding.

• Just the core of the end products has a foam-like structure, while the outer walls remain thick and strong. That’s why the products built through this method have a very high strength-to-weight ratio. In short, plastic parts built through structural foam molding are light-weighted, but they are strong and durable too.
• Generally, low-pressure is used in the structural foam molding, which is why the final products have a superior impact resistant ability. Thus, this method can be used for the production of such products which might need to be exposed under harsh circumstances.
• Plastic parts built through this method will have a great sound deadening and thermal insulating properties. Not just that, but another attribute of such plastic parts is that they offer great electrical insulation. Thus, structural foam molding is definitely a great choice when you need to build plastic products having these characteristics.
