We all know that many great inventions have been done in the field of plastic parts production, which has made it much easier to build strong and durable plastic products these days. But as long as it is about the production of strong plastic parts with minimum weight, then no other option can be better than Structural Foam Molding. That’s why the most manufacturing industries prefer Structural Foam Molding to build plastic parts with a decent strength-to-weight ratio.

Ahead in this blog, we have explained the key benefits of structural foam molding method, but before that, let’s understand how light-weighted plastic parts are built through this method.

The Process: Almost similar to conventional injection molding, structural foam molding is also a method of injection melted polymer into the mold. The only major difference is the inert gas or a chemical blowing agent, which is added to the melted polymer before injecting it into the mold. Apart from that, low-pressure is used for the injection process, and that’s why the end products have a foam-like core structure instead of being completely solid. Due to this foam-like core structure, end products are around 30% light-weighted compared to plastic parts built through traditional injection molding methods. Though, the outer walls of the final products are thick and solid, which gives decent strength and durability.

Now, when we know the structural foam molding process, let’s now have a look at the key benefits offered by this manufacturing method. Yes, a higher strength-to-weight ratio of the end products is a significant advantage of this method, but apart from that, it offers some other benefits as well.

Minimum Error Chances

As long as automated machines are being used for the structural foam molding, the error chances are very low. Though, the quality of the mold also plays an important role, which means high-quality molds can actually give you flawless end products.

Faster Production Cycle

Just because low-pressure is used for injecting the melted polymer, it doesn’t mean the production speed is slow, rather it gives faster production cycle, especially when using the latest machinery and stable molds.

Minimum Additional Surface Finishing

The plastic parts built through structural foam molding are usually flawless and don’t require additional surface finishing, which ultimately cuts down the production cost and time. Thus, it can also be described as the key benefit of manufacturing plastic products through this method.

Lower Manufacturing Cost

Compared to traditional injection molding, structural foam molding requires less raw material, which also lowers the manufacturing cost and allows you to make good profits.

So, having these many benefits, structural foam injection molding is unarguably the right choice for producing plastic parts with a decent strength-to-weight ratio.
