Material selection criteria, quality control standards, and manufacturing workflow for electrical discharge machining (EDM) graphite electrodes.

What are XRD’s material selection and quality control standards for EDM graphite electrodes?
XRD’s EDM graphite electrode manufacturing process is carried out in four stages:
- Material Selection by ApplicationGraphite grades are selected to match the specific electrical discharge machining (EDM) operating conditions of each job.
- Electrode MachiningGraphite electrodes are precision-machined, with tight control over surface finish and dimensional accuracy.
- Precision InspectionEach production batch is inspected for surface condition, dimensional accuracy, and batch-consistent electrical resistivity.
- Assembly & Fit VerificationThe fit and alignment between the electrode and its tooling are confirmed prior to release.
Quality control is anchored in electrode machining precision: the finer the electrode, the more accurate the mold cavity, and the finer the finished product.
Drawing on 30 years of graphite product R&D and manufacturing experience, XRD specializes in precision graphite electrode machining and supports a seamless transition from sample validation through to volume production.
