Today, there are many kinds of manufacturing techniques. One common and useful technique is called injection molding. Injection molding involves the production of parts by injecting a special material into a mold. The types of materials that can be used in this process include metals, glasses and, most commonly, a variety of types of plastics.
The material of choice is heated, mixed and then injected into a mold cavity. The mold cavity is typically filled to between 95% and 99% full. Afterwards, slight pressure is applied to perfect the mold. Once in the mold cavity, the material cools and hardens to the shape of the mold. Because temperature plays an important role in the process, injection molds and machines must be kept at specific temperatures and humidity levels to achieve
