Hansheng Automation (Dongguan) Co., Ltd.

Wire EDM (Electrical Discharge Machining) is one of the core precision manufacturing services offered by Hansheng Automation (Dongguan) Co., Ltd. Utilizing advanced CNC wire EDM machines, we provide high-precision part fabrication for industries including mold manufacturing, aerospace, precision instrumentation, and medical devices.

We specialize in handling hard, high-toughness conductive materials, as well as thin-walled and easily deformable parts. Our capabilities help you achieve reliable dimensional tolerances and excellent surface finishes for complex geometric shapes.

[Key Features]
High Precision: Our wire EDM processing tolerance can be controlled within ±0.01 mm or finer, making it suitable for high-precision molds and micro-instrument components.
Complex Contour Machining: Accurately cuts two-dimensional profiles that are difficult to process via traditional machining, such as narrow slits, profiled holes, and fine structures.
Wide Material Adaptability: Applicable to various conductive materials of high hardness and toughness, including hardened steel, cemented carbide, titanium alloy, copper, and aluminum.
Deformation-Free Processing: Since the electrode wire does not contact the workpiece directly, there is no macro cutting force. This makes it highly suitable for slender shafts or thin-walled components.
Excellent Surface Quality: Achieves a surface roughness (Ra) between 0.1μm and 0.8μm, helping reduce subsequent grinding steps and improving production efficiency.
High Material Utilization & Low Tool Cost: Removes only necessary path materials, allowing remaining blanks to be reused. Utilizing thin wires (brass, copper, or molybdenum) directly as electrodes eliminates the need for expensive custom-shaped tooling.
