Plastic Injection Molding

The Advantages of Injection Molding Are Contingent on the Precision of the Mold

Injection molding is an aptly-named manufacturing process. In the simplest of terms, it is the method of producing parts by injecting a substance/material into a pre-designed mold.  This type of production can be applied with many different materials including metals, glass, and rubbers/elastomers, although various plastics are most commonly used in this process.

In plastic injection molding, plastic granules are fed from a hopper to a heated chamber or barrel, where the granules are then melted.  The molten plastic is then pushed forward through a nozzle into the custom mold cavity by a screw-type plunger; because the mold is kept at a relatively low temperature, the plastic re-solidifies rather quickly into its new form or shape as soon as the mold has been filled.

Plastic injection molding can be used to manufacture a wide range of custom molded items in various shapes and sizes; examples for which the process is used consist of the following:

  • Bottle caps
  • Pocket combs
  • Storage containers
  • Hand-held gaming devices
  • Automotive parts/components

There are several advantages to the application of any injection molding process, notably:

  • Repeatability
  • Low labour costs
  • Minimal scrap losses
  • High-volume production
  • High-tolerance precision
  • Little need for parts finishing

From the perspective of manufacturers that utilize injection molding, being able to capitalize on any operational or financial advantages afforded by the process are of course contingent on the precision of the mold itself; ill-fitting or inexact parts produced from molds that are not made to specification will simply be unacceptable to their customers and/or end-users.

To avoid the possibility of such a detrimental impact on their businesses, manufacturers will find benefit in the precision mold-making capabilities of the specialists from Noble Precision.
