The Wonderful Plastic Injection Molding

Injection molding is one of the most preferred manufacturing processes by numerous companies today. Don’t get too caught with the fancy name because it is a very simple process that you can almost summarize it into 3 parts. First, raw material is heated in the machine’s barrel. Second, it is forced into a mold cavity. Then lastly, the heated material starts to cool and take the shape of the mold. Simple, isn’t it?

A plastic manufacturer would use this process to process various raw materials like plastic, metals, food, elastomers, and even glass! The possibilities are actually endless. Some of products made through this are military equipment, car parts, medical supplies, personal hygiene products like combs, custom buckles or even the laptop or smart phone you are using right now!

The Colorful Past

John Wesley, an American inventor, created the very first injection mold machine. It was patented in 1872. The molded plastic at this time were made to manufacture simple products like buttons on your shirt and comb for your hair. One hundred years later, James Watson made an improved version using gas. He improved the plastic molding process with the use of gas. This innovation made way for products to be manufactured at a much faster rate. Not only that, it made way for the manufacturing of more complex type of products like car parts, appliance parts, computer parts, and gadget parts. Well, you could also probably say “bless you” to this gas, don’t you think?

Various Equipment Used In Plastic Molding

There are many equipment used in this process and the widely used are:

The Mold

. It is also called as die. This is widely used to produce plastic parts from toys. Dies could be made of cold hard steel, alloy of beryllium and copper, aluminum, or pre-hardened steel. Each raw materials has its own set of advantages and disadvantage so you need to make sure that the one you will be using to manufacture your product is the best resin.

The Mold Storage

. Where do we place the molds after manufacturing is done? You can’t just leave it anywhere in the factory. Molds are very expensive and you need to take good care of it. Custom molds storage are used to keep the molds from being exposed to varying temperature and humidity. In this way, you can be assured that your molds can be used and reused for a very long time.

The Pros Of Using Plastic Molding

Extremely good quality products are made. Materials manufactured in this process are found out to be of high quality based on numerous research studies. The products are very durable. If you are not currently satisfied with the quality, it can be enhanced. Al you need to do is to reinforce the molded resin with other materials. That is something plastic belt buckle suppliers would really love to have!

It is environment-friendly. Excess product or scraps can be used and reused all over again. Nothing is thrown to waste! That is a big thumbs-up sign for Mother Nature, don’t you think?

It is practical, profitable, and worthwhile! Plastic molding is a very efficient manufacturing process and little or nothing goes to waste. The process is also fast and capable of making products in bulk too!
