Precision Mold Machining

Precision Mold Machining

Jinyang offers precision mold machining for FRP and SMC compression tooling, producing hardened cavities and inserts to tight tolerances. Our CNC machining and grinding capability delivers the smooth surfaces and accurate dimensions needed for high-quality composite parts and long tool life.

How It Works

Mold steel is rough-machined to the cavity shape, heat-treated for hardness, then finish-machined and polished to the required surface. EDM and grinding achieve fine details such as textures, undercuts, and logos. The finished insert is fitted into the mold base and proven before delivery to production.

Key Features

• Tight tolerance machining - precise cavity dimensions for repeatable part quality.

• Hardened tool steel - wear-resistant surfaces for long production runs.

• Polished finishes - smooth, glossy cavity surfaces for paint-ready parts.

• EDM and grinding - fine details, textures, and sharp corners achievable.

• Full inspection - CMM or gauge checks before mold acceptance.

• Material flexibility - P20, H13, stainless, and other tool steels available.

Technical Options

Mold inserts up to large press sizes, CNC 5-axis capability, surface grinding, and EDM. Texturing, chrome or nitriding, and cooling line machining available.

Typical Applications

SMC and FRP compression molds, injection mold inserts, thermoforming tools, and precision dies for composite production.
