Makerfabs provide a one-stop PCB Assembly service including molding design and production. Injection molding is a popular tool used for producing plasthetics, and that enables the plasthetics complete structure and precise dimension. The advantage of injection molding is fast production and high-efficiency, automatic operation can handle various forms and sizes of products. Injection molding is applicable for mass production and forming machining of complex-shaped products.
What is Plastic Injection Molding?
Plastic injection molding is a process by which granular plastic is fed from a hopper into a heated chamber where it melts and hardens to create parts. The granules are fed into the heating chamber by a screw-type plunger where they melt. As the plunger advances, the melted plastic is forced through a nozzle into the mold cavity. Since the mould remains relatively cold, the plastic solidifies almost immediately after the cavity is filled. After the plastic is injected, it must cool before the final part can be ejected from the mold. Plastic injection molding is by far the most common way to produce large volumes of finished plastic parts for every kind of commercial and industrial use. Molten resin is injected under high pressure into the cavity of a metal die and then rapidly cooled, forming a solid shape. A single cycle to make a finished part may take anywhere from a few seconds to minutes depending on part complexity and size.
