The basic structure of any injection mold consists of two halves: the fixed mold and the movable mold. The fixed half mounts rigidly on the stationary platen of an injection molding machine, while the movable half attaches to the reciprocating platen. This fundamental configuration supports advanced systems such as precision plastic injection molds, multi cavity hot runner mold systems, gas assisted mold technology, and collapsible core molds. Understanding how each structural type operates—with specific parameters and performance data—helps manufacturers select the right tool for complex parts, reduce cycle times, and avoid costly design errors.

Plastic mold fabrication is the foundation of high-volume, high-precision plastics manufacturing. From CAD design through CNC machining and trial runs, every step in mold making construction is optimized to produce durable, accurate injection molds for plastics that deliver consistent parts at scale.

Injection molding dies consist of two main assemblies: the stationary half, which bolts to the machine’s fixed platen, and the moving half, attached to the reciprocating platen. Beyond this fundamental split, advanced mold designs—such as collapsible core systems, gas-assist tooling, precision molds, and multi-cavity hot-runner assemblies—add targeted functions to meet challenging part requirements.

The basic structure of plastic injection mold is composed of two parts: fixed mold and movable mold. The fixed mold part is installed on the fixed plate of the injection molding machine,and the movable mold part is installed on the mobile board of the injection molding machine.
