Know the Benefits of Injection Molding Basics

The process of plastic molding is a simple process that can easily be understood by anyone, even to those who haven’t heard it at all! It involves the use of metals and plastics and a process that has been perfected since late 1800s. Although the injection molding basics has not changed, the methodology and raw materials have.

You have probably seen the finish products of this wonderful technique. Just take a look around your room for 10 seconds. It is next to impossible not to mention anything that is made of plastic. From dog collar buckles, appliances, packaging, plaques, car parts, kitchen utensils, fashion accessories, nameplates, and a whole lot more!  You name it, they’ve got it!

So how do we get to enjoy the wonderful benefits of this innovation? Let’s go to where it all starts.

Where the Magic Happens

The injection molding basics starts with choosing the right formula. It begins with an idea of making a specific product. Once the idea has been made, choosing the raw materials comes next. The materials are made of plastic pellets composed of polymers, both organic and inorganic. Additives are also used to make the process easier.

The plastic pellets are then tossed into the molding machines to be melted. This is just the first part of the magical process. It is then released into a big rotating screw with melting temperatures of around 400 F. Friction is the makes melting possible, as well as force.

The perfect formula for the filling phase of injection molding is made out of the following:  friction, force, heat. Once all requirements are made, pellets will liquefy. The melted pellets would go through the rotating screw to a valve, forcing the raw materials into custom-made molds, usually made of steel or aluminum. The cavity would be filled and the holding phase would be complete.

The outcome of the first two phases is very important for the overall success of the method. The choice of strong metals for the molds are also essential in making sure that all products manufactured is as good as the first one.

The pressure within the machines is kept then the heated raw materials are allowed to cool. Once it has cooled, the screw goes back to its previous position to begin the first and second phase. The finish product is then removed from the molds and sent to be decorated, assembled, and shipped. The magic is now complete and the process may start again!
