Precision Injection Mold

Precision Injection Mold

Jinyang precision injection molds are engineered for tight-tolerance plastic parts with consistent dimensions shot after shot. With hardened tool steel, precision-machined cavities, and balanced hot-runner systems, they meet the demands of medical, electronic, and high-precision injection molding.

How It Works

The mold closes, and molten plastic is injected through a hot runner into precision cavities. Controlled cooling channels solidify the plastic to hold tight dimensions. The mold opens and ejector pins remove the part, with process parameters tuned for repeatable precision across long runs.

Key Features

• Tight tolerances - CNC-ground cavities hold dimensions closely.

• Hot-runner option - balanced feeding for multi-cavity precision.

• Controlled cooling - channels minimize warpage and sink marks.

• Hardened steel - long tool life over precision runs.

• Smooth surfaces - polished or textured cavities to part spec.

• Repeatable - process and design tuned for shot-to-shot consistency.

Technical Options

Multi-cavity counts, hot-runner or cold-runner, mold steel selected by plastic. Tolerance grades and surface finishes to part specification.

Typical Applications

Medical components, electronics connectors, optical parts, precision gears, and high-end consumer products.
