Injection molding is a commonly used process in mass-production and fabrication of plastic parts. It is a procedure, in which melted plastic is forced into a mold, which is then ejected out when it gets cooled. A wide variety of products are manufactured using injection molding, which vary greatly in their size, complexity, and application. The injection molding process requires the use of an injection molding machine, raw plastic material, and a mold. The plastic is melted in the injection molding machine and then injected into the mold, where it cools and solidifies into the final part.
