Why is Structural Foam Molding So Reliable?
It is a method of manufacturing in which two components (polyol & isocyanate) are used to create polyurethane. This method is similar to the plastic injection molding process because that prepared polyurethane is injected into the mold, but the difference is that Structural Foam Molding doesn't require high pressure to form the product. This process is mostly used to manufacture such parts which are required to be lightweight and rigid. The main benefits of the structural molding process have been given in the following article so that you will be able to opt for the best for yourself. It Doesn’t Need High Pressures: In this process, an inert gas is mixed with the chosen plastic and when the mixture is injected into the mold, the inert gas gets expanded and it fills the mold cavity. Thus, high pressure isn't needed during the whole molding process because when the hot melt metal touches the colder cavities, it becomes solid and the final product gets prepared with thin layers and enough rigidness.
