Yishunyuan provides custom precision components across mold tooling, medical devices, automation, automotive, consumer electronics, optical and acoustic applications.
From Makino CNC machining centers to Charmilles EDM, Seibu wire-cut EDM and PG jig grinding, our process mix supports complex geometries, high-hardness components and tight-tolerance tooling.
We manufacture customized parts for molds, automation, medical devices, electronics, optical/acoustic applications and industrial assemblies, with material support from aluminum and stainless steel to carbide, ceramic and engineering plastics.
Founded in 2016 and located in Changsha, Hunan, Yishunyuan focuses on high-precision micron-level parts and assemblies for customers that need reliable small-batch, multi-variety, and custom manufacturing.
Support for non-standard components, special-shaped parts, jigs, fixtures, and precision inspection gauges based on customer drawings.
Experience with steel, stainless steel, aluminum, copper, brass, tungsten carbide, ceramic, engineering plastics and specialty materials.
Serving molds, machinery, medical devices, automotive, mobile phone connectors, consumer electronics, optical and acoustic fields.
4-axis, 5-axis and high-speed CNC milling for complex geometries, plates, housings and special-shaped components.
Precision grinding, NC EDM, wire-cut EDM and PG jig grinding for high-hardness and mold tooling components.
Slow wire-cut EDM for precision contours, inserts, punches and hard-material components that require stable dimensional accuracy and fine cutting quality.
Surface grinding and PG jig grinding for flatness, parallelism, high-hardness tooling details and micron-level finishing requirements.
Injection molding support for precision plastic parts, trial production and matched component manufacturing when projects require machined and molded parts together.
Equipped with projector, Zeiss CMM, microscope, height gauge, micrometer, dial indicator and calibrated gauge blocks, with dimensional inspection reports available.
