Injection molding: What Is It?
Plastic parts can be more cost-effectively made at scale using injection molding. Plastic molten is injected into a mold tool, then the solidified part is ejected. Mold tool costs are amortized hundreds or thousands of times, lowering unit costs to a few dollars. Injection molding makes plastic parts mass-producible. Because injection molding uses the same mold tool for all parts, it provides consistent quality across the board. Furthermore, injection molding produces complex parts with tight tolerances, making it the perfect choice for many industrial applications. Injection molding provides more materials, colors, cosmetics, polishes, and surface textures than CNC machining or even 3D printing. This makes it ideal for mass production of plastic components.
