Multi-cavity Injection Mold

Multi-cavity Injection Mold

Jinyang multi-cavity injection molds pack many identical cavities into one mold so every injection shot produces many parts. This is the standard way to achieve low unit cost for high-volume small plastic parts such as caps, connectors, and packaging components.

How It Works

A balanced runner system feeds plastic from the sprue to all cavities simultaneously. The mold closes, plastic fills every cavity, cooling channels solidify the parts, and the mold opens. Ejector pins push the full family of parts out in one cycle.

Key Features

• High output - dozens of identical parts per shot.

• Balanced runner - all cavities fill evenly for consistent parts.

• Lower unit cost - amortize mold cost over millions of parts.

• Precision cavities - all cavities machined to the same tolerance.

• Even cooling - channels around every cavity reduce cycle time.

• Hardened steel - long life for high-volume production.

Technical Options

Cavity counts from 2 to 128+, standard or hot-runner. Steel grades selected by plastic; cavity layout balanced for even fill.

Typical Applications

Caps, lids, connectors, buttons, packaging components, and other small high-volume plastic parts.
