When one has specific needs that call for specialized pieces made from plastic, there are many methods that could be used. Depending on the intended function and necessary durability of the part, the option field will become more narrowed. For most situations, custom injection molding is known to be easy, affordable and generally efficient.
This is a process by which molten plastic is injected into a mold to create a product, or component of one, in a quick and cost efficient manner. It may be used to make a singular item, or to mass produce a particular piece. When it comes to making parts of this type, there are many reasons why this is the preferred method of many manufacturers.
Versatility is perhaps the most prominent reason why most manufactures turn to this process as their first preference. It has been used to create an infinite array of products such as containers, electronic housings, combs, figurines, bottle caps, toys and even parts of car interiors. There are very few limitation on how small, large or uniquely shaped the products may be.
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.
Many advantages are found in choosing to use this particular method. These include have thousands of source materials available for production, very little waste generated from overflow and scraps, easy repetition, less required manpower and lower labor costs. As the molds make copies that are so precise, new products generally need little to no additional manual finishing.
The disadvantages are few, though they could be rather formidable under certain circumstances. For instance, there are some limits as to where the plastic components may be utilized or how much pressure they may tolerate. The biggest issue is usually the cost of the initial tooling investment, but this is usually recouped quickly if a large number of items are produced.
Specific requirements such as the piece's intended function, location and necessary pressure tolerance is going to powerfully affect what substances may be used in its construction. Polymers like nylon, polyethylene, polystyrene and epoxy are just a few of the many thousands of available material choices. Under certain circumstances, even elastomers, glass, some metals and confections could be utilized in the process.
