Injection Molding

Injection molding is one of the many manufacturing processes inventors must consider to make their prototype a mass-produced reality. Injection molding is used to create individual pieces, helping to bring uniformity and quickness to the overall creation of a product. Injection molding is a fairly simple process that can create some fairly complex pieces. Injection molding features heated, liquefied plastics and a mold. The mold is filled with the liquid and quickly dries, creating a uniform piece for the inventor’s product. There are multiple steps in the injection molding process. These steps include melting, injection, cooling and ejection. Each step is important to the overall method of injection molding and may change how you design each piece in your prototype. Melting is a fairly simple process, melting the plastic material into a liquid state. This can change how an inventor creates their individual parts, as they may need to change the product they used to fit with the injection molding process. The injection phase of the process actually injects the heated, liquid plastic into the mold that has been created for the part. The mold needs to be completely filled by the plastic and is therefore pressurized. The high-pressure liquid can fill all cracks, allowing for intricate and complicated mold designs. The chilling process is another important part of the injection process. The mold must be cooled, allowing the plastic to settle and solidify. The final aspect of the process, ejection, removes the plastic from the mold. It is important for inventors to understand all of the different aspects of injection molding as they design their prototypes. Inventors should work with manufacturers to understand what is possible through injection molding. This will make the prototype more realistic and more efficient. Injection molding provides inventors with plenty of opportunities. All inventors should consider this manufacturing process as they work to complete their prototype.
