Plastic injection molding is a highly efficient manufacturing process for producing many plastic parts. It involves injecting molten plastic material into a mold, allowing it to cool and solidify, and then ejecting the finished product. This process is repeated thousands, or even millions, of times to create large quantities of identical parts.

The process begins with the design of the mold, which is typically made from durable materials such as steel or aluminum. The mold consists of two halves, the cavity, and the core, which define the shape and features of the final product. The molten plastic is injected into the mold under high pressure, filling the cavity and taking on its precise form.
