71. Custom Injection Molding Process And Advantages

Injection Molding is a process by which most plastic molds are produced. We have dedicated and experienced designer team having knowledge in product design, custom molds and designing of core cavities for dies and plastic molding.

Custom injection molding has always been a fast moving, disordered and demanding business. Now a day, despite the competition and tight margins it also has a potential for profit. You want to succeed, you see the possibilities, but the global pricing and high expenses make it very difficult.

Process of Injection molding
The first step is plastic heated till it melts during the process of plastic injection molding. The mold can make by using any metal like steel or aluminum. The molten form is then allowed to cool down and set into a solid form. The plastic material thus formed is then retrieved out of the mold.

Next is the actual injection of the melted plastic. The plastic usually begins this process as pellets that are put into a large hopper. The pellets are then fed to a cylinder; here they are heated until they become molten plastic that is easily forced into the mold. The plastic stays in the mold, where it is being clamped under pressure until it cools.

The next couple of steps consist of the dwelling phase, which is basically making sure that all of the cavities of the mold are filled with the melted plastic. After the dwelling phase, the cooling process begins and continues until the plastic becomes solid inside the form. Finally, the mold is opened and the newly formed plastic part is ejected from its mold. The part is cleaned of any extra plastic from the mold.

Advantages of Custom Injection Molding
There are so many advantages of using custom injection molding process. The major advantage of injection molding is that it is very reliable and cost-effective. Also, this process produces smooth and finished products that require no further finishing.
