EDM Process Capabilities
Four EDM processes for drawing-based review.

Wire EDM
Through-profile cutting for slots, contours, inserts and conductive metal components.

Sinker EDM
Electrode-based EDM review for blind cavities, ribs, mold details and shaped features.

Small Hole EDM Drilling
Fast EDM drilling review for start holes, cooling holes and hard conductive materials.

Micro EDM
Fine-feature EDM review for small parts, micro slots and delicate conductive components.
Materials We Machine
Review common conductive metals and hard-metal related parts for EDM feasibility.

Tooling inserts and fixtures
Precision features for production support and workholding.
Medical and precision parts
Small features, controlled edges and inspection-driven components.
Automotive tooling
Prototype and batch tooling support for demanding production fixtures.
Electronics connectors
Fine slots, contact geometry and conductive material review.
Energy and oil/gas components
Material and inspection planning for robust industrial components.
Research and prototypes
Early-stage drawing review before production release.
Drawing-to-Quote Workflow
A practical review path from drawings and requirements to quotation and sample planning.
- 01Send drawings and requirements
Share material grade, drawing files, quantity, tolerance, finish and inspection needs.
- 02Review material and process fit
We check whether wire EDM, sinker EDM, small hole EDM or micro EDM is the right route.
- 03Confirm tolerance and surface requirements
Critical dimensions, finish passes and inspection method are reviewed before quoting.
- 04Quote and sample review
When needed, sample approval can confirm geometry, finish and process stability.
- 05Batch production planning
Approved requirements guide production planning, inspection and delivery review.
Why Work With JIANSHENG
Capability review before quotation, with process selection and inspection planning.
About JIANSHENGWe review the drawing before recommending the EDM route.
Material, geometry, access and tolerance are checked together.
Critical surfaces can be reviewed for finish, recast layer and post-process needs.
Sample approval can be planned before production when requirements are tight.
Reports, CMM needs, roughness and material documents can be discussed early.
