Plastic is just about everywhere you look, no matter what part of the country it is that you might live in. We rely on plastic immensely, using it to package our food, our beauty products, and our household essentials. Plastic is commonly used to make toys for children of all ages, and plastic can be found even in the clothes that we wear. So it is no doubt that plastic is increasingly more sought after – and not just within the United States but all throughout the world in its entirety. The data that has been gathered on the subject more than backs this up, showing that already more than 34 million tons of plastic were generated each and every year here in the United States alone by the time that we had reached the year of 2014. And in the years that have passed us by since, this number has truly only increased – and will only continue to increase in the years that lie ahead.
Of course, the way we construct plastic and make it into everything that it ultimately becomes has become more advanced than ever before. Things like the injection molded enclosure have grown more popular than ever, made possible through the use of injection molding. Aside from the injection molded enclosure, injection molding can be applied in a number of other different ways as well. And as anyone who has worked on or with an injection molded enclosure can likely attest to, there are actually a number of different kinds of injection molding, something that all people might not be particularly well aware of.
RIM is particularly common. RIM stands for reaction injection molding, and it is a type of injection molding that can not only create things like the injection molded enclosure, but things well beyond it as well. This makes RIM an ideal type of injection molding, as the injection molded enclosure, as important as it certainly might be, is by and large not the only way that injection molding can be applied in the world as we know it.
But how exactly does RIM work? How is it set apart from the rest of injection molding and even from processes such as that of structural foam molding? RIM is a process that involves the mixing of two liquid components that are then injected into a mold. In this mold, they will chemically react with one another and cure, and then the parts will be made. Typically, such a process is done to create polyurethane parts, which in and of themselves have a wide array of applications in the world as we know it.
Of course, there are a number of things that must be kept in mind when RIM is being used. For instance, it will be important to ensure that the walls of the mold being used are thick enough, as this can have a direct outcome on the final results of the endeavor. Typically, these walls should be at least one eighth of an inch, but it will all vary depending on what exactly is being molded and the process that it is going through (such as what chemicals are reacting to each other in the RIM process). And it’s important to know that RIM is not the only process by which things like the typical injection molded enclosure are created. In fact, this is not the case by a long shot.
In addition to RIM, processes such as encapsulation molding are also used. Encapsulation molding is widely popular, as too is structural foam molding. And all of these techniques will most certainly have their pros as well as their cons. Therefore, it is hugely important to understand these methods of plastic creation well – and how and when each such method will need to be used in order to get an optimal outcome. Fortunately, plastic is very much a lasting part of our world, and this is not something that is likely at all to change in the years that are ahead of us.
