Using Injection Molding In Manufacturing

By Genevive B. Mata


Creating plastic toys, pieces and components can be done in a number of ways, depending on certain factors such as to what the purpose of that item is to be. Each aspect of this procedure has to be carefully calculated to accommodate for each product's specific structural and functional issues. One method that proves most effective in many circumstances is injection molding.

This is a manufacturing process by which items are produced when the fabricating materials are injected into a mold. There are several substances that can be used to create the parts and multiple methods by which to do it. Which of these combinations is best will be determined by the performance specifics of the finished product.

When it comes to making either a single piece, or having the same item mass produced, this is the most commonly utilized method for plastic fabrication. This is how products like bottle caps, molded figures and toys, kitchenware, containers, combs, certain components for machinery and housings for electronics are generally made. Many parts of an automobile, from a small accent piece to a full door panel, may also be created this way.

A large material selection and a low cost of labor are just two of the many advantages to this type of manufacturing. Thousands of exact copies may be produced in a short time and with the right substance mixture, the items are more stress tolerant. Pieces rarely need additional finishing as the molds are precisely tooled and generate a minimal amount of waste.

Unfortunately, there are also a few disadvantages to this procedure. To begin with, the process itself has particular limitations due to the way it must be set up and how it operates. There is also the issue of the initial tooling investment for new pieces being quite expensive, though they do tend to pay for themselves when molds are used multiple times.

Practically any polymer, including thermoplastics of all types and several different thermosets and elastomers, are great for this process. With so many different types of materials available, the fabrication choices are beyond numerous. The individual substances can be blended or mixed with alloys to create designer formulas to best suit the purpose.

What the molded piece will be used for will determine which material, or mixture of multiple ones, will be the best choice. Some products will need to withstand a greater amount of stress or function in more intense temperatures than others will, so the composition must meet those standards. The range of possibilities of what may be created in this manner is vast and varied.
