Plastic Injection Molding Companies Have Much to Offer

Plastics are quickly becoming some of the most versatile and cost-effective materials in the manufacturing industry today. In fact, plastic injection molding companies can produce high-quality materials faster than ever. Here are some of the benefits of the process of injection molding.

How it Works

Plastic granules go into a hopper and get fed into a hot barrel. The plastic material then is melted and injected into mold cavities. It is different than casting parts in which molten material is poured into open molds. With casting, the molds are closed and then heated.

The injection molding process uses closed molds so molten plastic can be forced into the molds. This produces a high-quality product. In fact, it is possible to manufacture things with great detail and intricate features.


Best plastic injection molding companies can produce precision parts with amazing accuracy. In fact, some parts can meet tolerances as high as .0005 of an inch. This can eliminate the need for machining parts.


Thanks to automated technology, plastic injection molding companies can manufacture parts quickly. This gives customers quick turnaround times and makes it possible to fill urgent orders. If you sometimes have “rush” orders from your customers, this is an important point to remember.

Labor Costs

It takes few people to produce items with injection molding equipment. This helps manufacturers save money on production costs. These savings can then be passed on to the customer, resulting in lower prices for your company and increased efficiency.


It is possible to create a wide range of parts with injection molding. If you want to change colors, this is not a problem. Many parts today are manufactured with injection molding equipment. In fact, plastic injection molding companies can design and produce prototypes for your research and development staff, and they can manufacturer your parts for you.
