Every single manufacturer working in the field of manufacturing plastic parts must be aware of the key advantages of thermoplastic foam injection molding.

Exploring 4 Key Advantages of Thermoplastic Foam Molding

People working in production field know how difficult yet important it is to choose a suitable manufacturing method. It entirely depends on the production method, whether you’ll be earning a good profit or not. On this note, if you don’t have much knowledge about different manufacturing modes, then it will be better to consult with an expert to find out which method will be suitable for you. Here in this blog, we’re discussing 4 key advantages of manufacturing plastic parts through Thermoplastic Foam Molding. So, if you are also working in the field of manufacturing plastic products, then continue reading the following information.


First, let’s understand how Thermoplastic Foam Molding is different from standard injection molding process. It is a low-pressure process that provides multiple advantages, which can be beneficial for your business ultimately. In thermoplastic molding, plastic granulate and a blowing agent are together injected into a pre-designed mold. These are the two main differences which make Thermoplastic Foam Molding different from normal plastic molding. Now, let’s have a look at 4 key advantages of this production method.


  1. It is a method that gives you complete freedom to build plastic parts with intricate and complex designs. In simple terms, because of the low-pressure used for molding process, it’s possible to put intricate designs on plastic parts.
  2. Plastic products built through this method generally don’t require additional surface finishing. This is because parts built through thermoplastic foam molding don’t have any sink marks or after-shrinkage spots. In brief, it can be said that you can build close to perfect plastic parts through this method.
  3. Not only for large-scale production, but it is suitable even for small-scale production. Making it simple for you, it is a low-cost manufacturing method, which means it is a good option even when you are required to manufacture plastic products on a small scale.
  4. You must also know that end products built through this method can have up to 40 mm wall thickness. Thus, it is a good alternative, even when you need to build strong plastic parts. Considering all these advantages, you can’t deny that thermoplastic molding is a good alternative in many cases.
