A Brief Introduction 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. In this process the material will be heated, mixed and forced into a mold. 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, musical instruments, automotive parts, and even military equipment. We will narrow our discussion in this article and only discuss plastic injection molding. First we will look at the history behind plastic injection molding. In 1872 John Wesley, an American inventor, patented the first machine used for plastic molding. The molds were often very simple and some of the first products that were produced were combs and buttons. Moving forward a hundred years, and a new machine has been invented by the James Watson, this machine will drastically change the process. Not only did this speed up the process but it also allowed people to produce much more complex items. Next we are going to take a look at the equipment that is often used to in plastic injection molding. The mold or die, is one piece used in the production of plastic pieces. 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. Of course this is where the mold will be stored when it is not in use. Custom molds will be expensive so it is important for the storage container to be top of the line. Having proper temperature and humidity for your mold will ensure that it lasts as long as possible.
Getting To The Point – Molds
Lastly, we will 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. These machines can produce products very quickly and can produce large quantities. Another way it saves on costs is because it is efficient and leaves little waste behind. Along with it being efficient and creating little waste, it is also very eco friendly. Research has shown that parts and products manufactured through injection molding are high quality and extremely durable. If you are interested in further reinforcing your product then you can add additional materials to your molded plastics.
