A Quick Start Guide to Plastic Injection Molding


Injection molding is a very popular form of manufacturing; it may even be the most popular type of manufacturing in the world. During this manufacturing a material is heated, mixed and then forced into a molding cavity. The piece will take the shape of the mold once it is cooled. This process can be used with many different materials, some of the most popular are metal, glass, confections, elastomers and plastic. There are endless amounts of products that are created in this manner, some of the most common are medical supplies from the industrial plastic parts suppliers, musical instruments, automotive parts, and even military equipment. We will narrow our discussion in this article and only discuss plastic injection molding.


We will start off by taking a quick look at the history of plastic injection molding. The first machine used for plastic molding was patented all the way back in 1872 by John Wesley, an American inventor. The molds were often very simple and some of the first products that were produced were combs and buttons. Fast forward a century and a guy by the name of James Watson invented a machine that was gas assisted that would drastically change the plastic injection molding process of plastic injection molding services. This new machine and process makes it possible to produce complex items at a much faster rate.


Next we will look at some of the equipment that is used in the plastic injection process. The mold or die as many refer to it is one tool that is used to produce plastic parts. There are a couple different materials that are used such as aluminum, steel, or copper alloy, each one will have benefits and disadvantages, the one that is used will depend on what it is being used for.


Another important piece of equipment when it comes to plastic injection molding is the mold storage. It might be obvious but this is where the mold will be kept will the mold is not being used. A custom mold is an expensive piece of equipment so you storage should be very protective. The storage needs to be kept at a good temperature and the humidity must be right, this will guarantee that your mold lasts for a long time.

The last thing we will do is look at the advantages of plastic injection molding. There are many advantages but one of the biggest for manufacturing purposes is that it is cost effective. This process can create products very quickly and has the ability to produce products in large quantities. Another reason it will save money is because of how efficient it is, these machines leave behind little waste. Because it leaves little waste, it is also economically friendly and save for the environment. Research has shown that products and pieces that are manufactured through injection molding are extremely durable and high quality. To increase quality, all you need to do is reinforce the plastic with another material.
