For cost-effective large-scale plastic part production, injection molding is the optimal solution. The process involves injecting molten plastic into a mold tool, then removing the solidified part. This rapid cycle can repeat hundreds or thousands of times, amortizing the mold tool cost and reducing unit costs to a few dollars or less. Since each part uses the same mold tool, injection molding ensures uniform quality across every part. Moreover, it offers the broadest selection of materials, colors, cosmetics, polishes, and surface textures compared to CNC machining and 3D printing.
