What You Need To Know About Plastic Injection Molding

Nowadays, more and more people- along with their businesses -are using plastic injection molding for several purposes in their everyday lives. But, most don’t know what goes on behind the scenes of manufactured products, nor the method used to do it. Plastic injection molding is used to create some of the most prominent things in our lives and it’s important to know a little bit about it.

The first part of the injection molding process includes heating up the plastic until it is soft enough to be injected into a mold. Then, the moving and fixed platens of the injection molding machine hold the molding tool together under pressure as the soft, molten plastic is injected into it. After all of the plastic has been injected into the mold, more pressure is applied from the mold itself to ensure that all cavities are filled. The plastic parts are then allowed to cool and solidify within the mold. Once the plastic is fully cooled and a guaranteed solid, the mold tool separates, releasing it from the pressure it had been using to hold it together. Lastly, air blast, rods, or a plate is used to aid in the ejection of the completed plastic mold from the injection molding tool. This process is then repeated with any other molds that need to be made. From the time the plastic begins to heat to the time that it is ejected as an individual plastic replication of the mold is the entire plastic injection molding process.

Now, you know of the process that goes on to create the manufactured plastic products that you use today. It’s extremely important to know and appreciate, and without it, we wouldn’t have some of the most important things in our world today.
