Unearth Key Advantages Offered By Structural Foam Molding
Injection molding will unarguably top the list if talking about the most common methods used for manufacturing plastic products these days. It is way better and more reliable than many other alternatives when it comes to producing identical plastic parts on a large scale. Though, there are different types of injection methods used in different circumstances, depending on the product’s requirement. Here, we are talking about Structural Foam Molding, which is also an injection molding method, but it is used in some specific situations because of its unique and unparalleled advantages. Usually, plastic injection molding is a process in which melted polymer is forced into a metal mold using high-pressure. However, in Structural Foam Molding, an inert gas is also added to the melted polymer at the time of the injection process. This inert gas acts as a chemical blowing agent that expands after the injection process. Apart from that, Structural Foam Molding requires low-pressure so that the chemical blowing agent will get enough time to expand.
Now, when you know how structural foam molding is different from traditional plastic injection molding, let’s have a look at the key advantages offered by this manufacturing method. 1. The inert gas or the chemical blowing agent added to the melted polymer was actually to lower the overall weight of the final product. In brief, plastic parts built through structural foam injection molding have a foam-like core structure instead of being completely solid, which ultimately lowers the final weight of the products by around 30%. However, the outer walls are thick and solid, which is why the end products are strong and durable too. So, the most crucial benefit is that it allows you to produce lightweight products without sacrificing the strength and durability. 2. Because low-pressure is used in the injection process, the overall power consumption is much lower, which ultimately lowers the production cost too. Moreover, less raw material is required to form the desired products, which also help to minimize the manufacturing costs. Thus, it is a cost-effective production method that allows you to sell your products at very competitive prices, and you will still be making good profits.
