Qualities of Plastic Parts Produced Through Structural Foam

Posted by ChinaCasting on November 25th, 2021

Can you imagine a picture of our world without the existence of plastic products in it? There’s no denying that plastic is harmful to our environment as well as to the ecosystem, but you also can’t deny the fact that plastic has some unique characteristics, and we still don’t have an alternative to replace it. There are multiple advantages of plastic, as it is a lightweight yet strong material that can withstand under harsh circumstances. This is the reason why it is now being used in many fields.

 

Coming to the point, we are here talking about Structural Foam Molding, which is a manufacturing method through which plastic parts are built. It is a method similar to traditional injection molding, but with a couple of major differences. In the Structural Foam Molding, an inert gas is also added to the melted polymer, and low-pressure is used for the injection process. As a result, the end products are much different from the plastic parts built through the conventional injection molding process. Continue reading this blog to discover main qualities of plastic products manufactured through Structural Foam Molding.

 

Higher Strength-to-weight Ratio

Because of the inert gas, the core of the final products has a foam-like structure instead of being completely solid. This is the reason why the weight of the plastic parts built through this method is around 30% lesser. However, the outer walls are thick as well as solid, which gives enough strength to final products. In short, foam molding allows you to build plastic products with a  very high strength-to-weight ratio.

 

No, or Very Less Additional Surface Finishing

Since low-pressure is used in the injection process, final products don’t have too many sink marks. Hence, there’s no need to spend a large amount of money on additional surface finishing.

 

Easy to Build Complex Plastic Parts With Precision

Low-pressure allows you to build plastic products with complex designs on them. However, you ought to use advanced, automated machinery if you want to build precise plastic products through Structural Foam Molding. What’s more, the quality of the mold can also have an impact on final products
