Custom Injection Molding Process and advantages

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

What is the 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.

The Factors involved in the Custom Injection Molding process are :

•    The pressure of injection can be changed to change the hardness of the final product.
•    The thickness of the mold also governs the quality of the article produced.
•    The temperature for melting and cooling determine the quality of the plastic formed.

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.

•    Substantial cost savings due to availability of skilled 3D professionals at lower cost
•    High Quality standards are maintained
•    Quick Turn around Time
•    Reduces capital costs of infrastructure
•    Attractive Advanced technology
•    Increased capacity for business expansion and diversification
•    Improve employee satisfaction with higher value addition jobs
•    Allows you to focus on core business
•    Saving in human resources
