Mould & Tooling Manufacturing
Copper and brass electrode tubes are widely used in mould and die production, including wire-cut starter holes, ejector pin holes, cooling channels, and precision auxiliary holes.
Aerospace & Automotive Components
EDM drilling tubes support precision hole machining in components that require stable discharge, controlled flushing, and consistent hole quality, especially for hard or difficult-to-machine materials.
Medical, Instrument & Precision Parts
For small-diameter precision holes, EDM electrode tubes can be used in instrument parts, medical device components, and other high-precision metal parts requiring clean and repeatable hole machining.
Dimensional Inspection
Outer diameter and length can be checked before shipment to support stable feeding and machining performance during EDM drilling.
Channel Consistency
Single-hole and multi-channel structures are inspected to help maintain smooth flushing, chip removal, and consistent electrical discharge during machining.
Surface & Straightness Control
The tube surface and straightness are controlled to reduce feeding instability and support reliable performance on EDM drilling machines.
Packing Protection
EDM electrode tubes are packed to reduce bending, surface damage, and contamination during international transportation.
