Dongguan Yiding Technologies Co., Ltd.
Committed to Quality, Driven by Precision
Add to Cart
Our EDM machining services are designed for industries that require ultra-precise machining of hard materials or complex geometries that conventional cutting methods cannot achieve; by using controlled electrical discharges between an electrode and the workpiece submerged in dielectric fluid, EDM enables us to process conductive materials with unmatched accuracy, making it particularly valuable for mold manufacturing, aerospace components, medical instruments, and intricate automotive parts.

Wire EDM: Ideal for cutting intricate profiles and fine details with sharp internal corners that milling cannot achieve; capable of handling complex shapes while maintaining dimensional stability.
Sinker EDM (Die-Sinking EDM): Used for creating deep cavities, precision molds, and detailed contours; especially effective for hardened materials where traditional cutting tools wear out quickly.
Hole Drilling EDM: Provides high-speed drilling of small, precise holes in hard materials, making it suitable for aerospace turbine blades, injection molds, and precision cooling channels.
Extreme Precision: Tolerances up to ±0.002 mm
Material Versatility: Machine hardened steel, carbide, titanium, and superalloys
Complex Geometries: Sharp corners, thin walls, intricate contours achievable
No Tool Pressure: Prevents deformation of delicate parts
Superior Surface Finish: Polished-quality finishes with Ra 0.2 μm possible
Cost Efficiency: Ideal for low-volume, high-complexity production and tooling
We apply strict quality control measures throughout the EDM process; every part undergoes initial feasibility checks, in-process monitoring, and final inspection using CMM and high-resolution optical measuring systems, ensuring compliance with international standards such as ISO9001, DIN, and ASTM, and guaranteeing that the final product meets or exceeds customer expectations.
