CNC Machining Plastic VS Plastic Injection Molding

Plastic is all around us. We use items made of plastic every day. From the smallest necessities in the home to some of the biggest parts and equipment in industry, plastic is a material of vital importance. Simply put, it would be impossible to imagine our modern way of living without using most of the devices made from plastic. But wait, have you ever been curious about how the items you use on a daily basis are made? I'm sure that you've ever asked yourself about the actual methods that are used for processing plastic. We've all been there at some point.

Some of us, aside from being curios were also eager to research and learn more about how the plastic items they use are made, while others still haven't found time to do this. If you belong to the second group, you're welcome to join us in exploring the “wonders” the two main methods of processing plastic are capable to do. More specifically, keep on reading to learn about CNC machining plastic and plastic Injection molding. Or, if you are new business owner involved in making plastic products or parts, here's a simple and brief comparison between these two methods, which will make it easier for you to choose the best option for the needs of your business.

CNC Machining Plastic is a processing method which includes deriving certain shape from a big plastic shape by cutting the material using special machines controlled by special computer software. On the other side, plastic injection molding is a procedure of shaping the plastic by previously heating the plastic to high temperatures. This means that these two methods are completely different but are used for a similar purpose. So, the question which one is better.

One of the main difference between CNC machining plastic procedures and the plastic molding procedures is the price. Namely, CNC plastic machining is in general more that twenty times more expensive than plastic molding. However, in cases when you need more parts to be machined plastic molding turns out to be much expensive. More than that, once you create a plastic mold, you won't be able to change it easily.

CNC machining plastic is significantly more precise and accurate method that produces large numbers of products with high level of uniformity. This means that no matter how much products you need to shape, the chances of imperfections on the product surface nearly don't exist. Moreover, here are some of the main advantages of CNC machining plastic, which make this material-processing method a reliable option.
