YIJIANG Automation Precision Machining Solutions

YIJIANG has long specialized in precision machining of non‑standard automation parts, industrial robots, lithium‑ion battery equipment, semiconductor equipment, 3C intelligent equipment, logistics sorting equipment and structural parts for non‑standard production lines. We fully understand core working requirements of automation equipment including frequent start‑stop, high‑speed reciprocation, precise positioning, long‑term continuous operation and low‑clearance transmission. Equipped with mature capabilities in DFM design optimization, structural improvement, tolerance adjustment and customized processes, we excel in machining special‑shaped complex cavities, thin‑wall lightweight components, high‑strength wear‑resistant parts, high‑precision shaft‑hole fittings and micro‑feature parts. With a complete cluster of 3‑5‑axis precision machining equipment, we strictly control dimensional accuracy, geometric tolerances and surface roughness, while meeting performance requirements such as wear resistance, corrosion resistance, fatigue resistance, lightweight design and anti‑static properties. We support rapid iteration of R&D samples, flexible small‑batch production and stable mass delivery. Our products feature high consistency and interchangeability with full‑traceable quality, effectively reducing customers’ later assembly and debugging costs, and providing reliable precision part support for various automated intelligent equipment.

Our Machining Capabilities

Multi‑axis CNC Precision Machining Capability

Supported by 3/4/5‑axis linkage machining centers and turn‑milling composite equipment, complex curved surfaces, special‑shaped structures and multi‑feature parts can be formed in one clamping to minimize clamping errors. Dimensional tolerance is stably controlled within ±0.003mm, meeting high‑precision machining requirements for automation transmission parts, structural shells and tooling fixtures.

Large & Extra-Large Injection

Engineered for large-scale structural components like automotive bumpers and industrial housings, our 2000T–4500T injection units handle parts with projected areas up to $4.5m^2$. Our advanced thermal-controlled runner technology guarantees stringent wall thickness deviation control within $\pm 0.05mm$.
