What Is Plastic Injection Molding?
Used to create large quantities of plastic parts in succession, plastic injection molding is a manufacturing process that produces molds from thermoplastic and thermosetting materials.
These plastic materials are placed into a hot barrel, mixed, and forced into a mold cavity by a ram injector or reciprocating screw. Then, the materials cool and harden to the configuration of the mold cavity, creating the finished injection-molded parts. The time it takes to produce a finished part depends on its size and complexity, and can range from mere seconds to a few minutes.
By taking advantage of custom automation using robotic parts handling, automatic and semi-automatic runner systems, and robotic delegating, Atlantis Industries eliminates the typical sources of product variation.
When considering plastic injection molding for your needs, there are many advantages to factor in. One of the biggest advantages is repeatability. After your particular mold is created, every single part it produces is exactly the same.
Our Quality Management System ensures all processes are:
Other advantages of plastic injection molding include tight tolerances, low labor costs, broad range of material selection, marginal waste and in most cases no finishing required.
Common Applications and Materials In Plastic Injection Molding
Plastic injection molding techniques can create countless parts, from miniature components to whole body panels of vehicles. Atlantis Industries produces complex parts and assemblies in the defense, medical, automotive, consumer, commercial firearms, pharmaceutical, fringe medical, and industrial markets.
Materials Used By Atlantis Industries Include the Following:
Plastic Injection Molding Cost Concerns and Common Variations
When evaluating the cost of manufacturing, you must consider the size and complexity of the mold and parts produced, as well as the number of cavities in the mold. Initially, the manufacturing cost may seem high, but the individual price per piece is comparatively low. The cost is relative – the larger quantities produced means the price overall decreases.
Most plastic injection molding processes are created by using the methods described above. However, there are several important molding variations to consider:
Common Finishes in Plastic Injection Molding
The finished look of a product greatly affects its market success. The outward attractiveness and appeal of the part, the quality of the surface’s appearance, and the texture are all crucial factors that influence a customer choosing your product instead of another. One way to make your product unique is by choosing a creative surface finish.
During the design stage, the surface finish of your custom plastic injection molded parts can be determined. Atlantic Industries has many surfaces finishes for you to consider. Using both aluminum and steel molds offers more choices.
