What is an injection mold?

An injection mold is a specialized tool used in the manufacturing process of injection molding, where molten material—usually plastic—is injected into a mold cavity to form specific shapes. The mold is typically made from steel or aluminum and consists of two halves: the cavity side and the core side. Injection molds are essential for producing high-volume, precise, and repeatable parts for industries like automotive, consumer products, and electronics. Designing and maintaining these molds requires technical expertise to ensure product quality and efficiency.
