<div class='uawarticle'>What's the most prevalent manufacturing process in the world today? You might guess steel, glass or textile manufacturing, for starters. <br />
<br />
Get ready for a surprise: <a href='http://www.plasticstoday.com/communities/injection-molding'>plastic injection molding</a>. Plastics manufacturing, in layman's language.<br />
<br />
No kidding- manufacturing experts believe more products are made using this production process than any other method in the world. And a quick glance around your own little universe does nothing to disprove it. From the plastics in your car, (and under the hood), to the plastic spatula in your kitchen, to the plastic chairs at work, injection-molded plastics are as ubiquitous as they are unobtrusive. <br />
<br />
And as close as your fingertips; you are probably reading this article on a computer made up primarily of injection molded plastic parts. <br />
<br />
So what exactly is plastic injection molding? No matter what you're making, the process is strikingly similar in every instance: plastic granules, or pellets, are poured into a bin, heated, than "injected" or forced into a mold, which shapes the plastic part.<br />
<br />
Unlike other raw materials, plastic is infinitely malleable when molten, and can be molded into an endless number of forms. <br />
<br />
In most circumstances, (compared to metal, say) it is also the least expensive material to be used if many thousands or millions of identical parts are required. Plastic injection molding equipment also requires fewer personnel than other kinds of industrial machinery. And the finished plastic parts require little more work, as most of the time they pop out the correct size, shape and color. <br />
<br />
But the equipment used in the plastic injection molding process can be very expensive. For example, molds can cost somewhere in the six figures, depending on their complexity, and the complexity of the plastic part they're producing. <br />
<br />
A plastic injection mold usually consists of two main components, the injection mold and the ejector mold. After it is heated, melted plastic enters the mold through an opening in the injection mold called a sprue. The liquid plastic flows through the runner and enters one or more design openings and into the cavity of the mold to form the required part. <br />
<br />
The amount of plastic required to fill the inside of a mold is called a shot. Manufacturers must ensure that trapped air in the mold can escape through air vents that are built into the metal. If not allowed to vent, this air can prevent the molten plastic from filling the entire mold which will, understandably, mean an imperfectly-shaped part. In fact, this trapped air can become so compressed that it explodes and burns the surrounding plastic material.<br />
<br />
So you now you know a little bit more about the most common manufacturing process in the world! So go out and win a bar bet!<br />
