There are many industries where plastic parts are required to be manufactured through structural foam molding as it provides some unique advantages and that's why it is now a very popular manufacturing method.
We have seen many new discoveries in recent times and all of them have made human life better and more convenient. The same is the case in the field of manufacturing plastic parts, i.e. several manufacturing techniques have been discovered in recent years. We are here talking about the Structural Foam Molding which is now a very popular method used for the production of plastic parts. If you are also planning to start working in the field of manufacturing plastic parts, you need to know the main characteristics of Structural Foam Molding in order to find out why it is believed to be a suitable manufacturing method.
It is a process similar to the conventional injection molding method as the production is done by injecting plastic (in its liquid form) into a pre-designed mold. The chemical blowing agent (generally an inert gas) used in the structural foam molding is the only thing that makes it different from the normal injection molding process. In simple words, an inert gas is injected into the mold along with fluid plastic which is why the core of the final products has a foam-like structure while the outer walls remain thick and solid.
Now, let's find out what are such situations when Structural Foam Molding is considered to be the best method for the production of plastic parts.
There are many fields where lightweight plastic parts are needed and no doubt that it is the best method for the production of such products. We have already mentioned that inert gas is used during the injection molding process, which is why the products have a foam-like structure. The presence of air in the core minimizes the overall weight, and it means that no other methods can be better for the production of lightweight plastic parts than structural foam molding.
Just because products are light-weighted, you don't need to worry about the strength of final products because the outer walls remain thick and strong. In short, this method makes it possible to produce plastic products with a great strength-to-weight ratio, and that's why it is preferred by many manufacturers all over the world.
