Custom Injection Molding Has Much Versatility

By Genevive B. Mata


There are multiple methods by which one may create specialized plastic pieces to fit their specific needs. The field of options will be narrowed somewhat depending on the intended use and other circumstances of functionality and durability needs. One of the easiest and most efficient ways to manufacture unique products is to use the custom injection molding process.

During this process, a molten material is injected into a specialized mold in order to create pieces quickly and efficiently. It could be used for the production of a singular item, or as a means to manufacture any number of exact replicas. For this type of products, the simplicity and preciseness of the method makes it the preferred choice for many companies.

Versatility is probably the most attractive quality of this process and the primary attraction for many manufacturers. It has proven itself effective in creating a wide array of products ranging as far as electronic housings, containers of all sorts, figurines, toys, combs, bottle caps and even parts of car interiors. The limitations on size and shape are very few.

As a means of mass producing large quantities of an identical piece, this is generally the most ideal manufacturing option. Using molds that have multiple cavities of identical design in them allows a single cycle to generate a larger quantity of product at once. In this manner, needs are met quicker which means less time and money spent on production.

The advantages of using this particular method are both strong and plentiful. Among them are a large selection of available source materials, minimal amount of waste created by scraps, the ability to repeat the process time and again, and comparatively low labor costs. Because molds produce such precise copies, there is very little finishing to be done once the items are released.

The disadvantage, though few, could prove formidable in some circumstances. One of them is the fact that the pieces made in this manner may not be able to be placed in certain situations and might not be strong enough to handle high pressure loads. The most prominent concern is usually the investment of initially tooling the molds, however in mass production, this cost is quickly covered.

The substances that might be used to create a product is going to depend primarily on certain details such as how strong the piece is required to be, where it will be placed and what its intended function is to be. Among the thousands of available material choices are polymers like polystyrene, polyethylene, nylon and epoxy. In some cases, things like confections, elastomers, glass and various metals may also be considered.
