Anyone who is working in the field of manufacturing plastic parts must be aware of the primary advantages of structural foam molding, as it is now one of the most popular production methods

Unearthing 2 Primary Advantages of Structural Foam Molding

Due to some distinctive characteristics of plastic products, they are now being used in many fields, considering plastic is a durable, strong and light-weighted material. Plastic is unarguably an irreplaceable material because of some of its unparalleled benefits. It seems quite difficult to imagine a world without plastic products because there are many fields where no other alternative can replace the plastic. Coming to the point, we are here talking about the 2 primary advantages of Structural Foam Molding, which is basically a manufacturing process through which, plastic parts are built.


However, before you start exploring the key benefits of Structural Foam Molding, it’s better to learn a little more about this production method. The process is as simple as traditional injection molding, but with two key differences. Just like traditional molding methods, Structural Foam Molding is also a process of injecting the melted polymer into a mold. The two major differences between structural foam injection molding and normal injection molding are that an inert gas is also added to the melted polymer, and low-pressure is used to inject liquid plastic into the molds.


Now, when you know how the structural molding is different from traditional molding methods, let’s find out what are the key advantages offered by foam injection molding. Knowing the primary advantages of Structural Foam Molding can help you understand what are those situations when this method can be the right choice for your business.


  1. No other production method can be a better choice than this method when it comes to producing light-weighted plastic parts with a very good strength. This is simply because of the addition of an inert gas in the melted polymer. The inert gas acts as a blowing agent, which expands when injected into the mold. As a result, the fore of the end product has a foam-like structure while the outer walls are thick/solid and strong, which is why the plastic parts built through this manufacturing process have a very good strength-to-weight ratio.
  2. The low-pressure used for the injection process allows you to conduct production with minimum error chances. On this note, structural foam molding is suitable to produce plastic parts with complex designs on them. However, it also depends on the quality of the molds and machinery used in the injection molding process. So, structural foam injection molding is definitely a flawless manufacturing method as long as you are using high-end resources from iMold USA, LLC, which is a trusted plastic molding agency.
