Custom Wire EDM Parts & Machining Services

Product Overview

Wire EDM (Electrical Discharge Machining) parts are high-precision components manufactured using continuous-travel brass or coated molybdenum wires to erode conductive materials through thermal sparks. This process handles hardened tool steels, tungsten carbide, exotic superalloys, and graphite without mechanical cutting forces, eliminating distortion on thin-walled or intricate geometries.

Target applications include stamping die inserts, injection mold components, extrusion dies, aerospace fuel nozzle parts, and medical surgical guide components. Core manufacturing capabilities support straight cuts, 4-axis simultaneous taper cutting (up to 45 deg), micro-hole starting, and ultra-fine corner radii down to 0.05 mm.

Key Features

Sub-Micron Dimensional Accuracy:

Achieves tight linear tolerances down to +/-0.001 mm via closed-loop linear glass scales and automated tension control.

Sharp Internal Corners:

Delivers internal radii significantly tighter than traditional milling tools, enabling precise mating profiles for progressive stamping dies.

Zero Cutting Force Processing:

Generates no physical cutting stress, preventing deformation on thin-walled profiles, fragile fins, and slender ribs.

Hardened Material Machining:

Directly profiles materials after heat treatment (up to HRC 65+), neutralizing post-hardening thermal distortion.

Controlled Surface Integrity:

Minimizes recast layer depth and micro-cracking through optimized pulse energy settings and multi-stage spark trimming.

Flexible Production Scale:

Scales efficiently from single-piece prototype tooling inserts to production batches of thousands of identical components.

Applications

Automotive:

Progressive stamping die inserts, punch pins, extrusion dies, and high-precision transmission valve components.

Medical:

Surgical cutting guides, titanium orthopedic implant fixtures, and micro-fluidic mold cores.

FAQ

Q: What is your Minimum Order Quantity (MOQ)?

A: No strict MOQ. Orders are accepted starting from 1-piece prototypes up to mass production volumes.

Q: What is the tightest tolerance you can consistently hold?

A: Linear tolerances can be maintained down to +/-0.001 mm under temperature-controlled workshop conditions, depending on material geometry and thickness.

Q: What file formats are required for quoting?

A: 3D CAD models (STEP/IGES) combined with a 2D engineering drawing (PDF) specifying GD&T tolerances, service finish requirements, and material grades.

Q: Can you machine pre-hardened materials?

A: Yes. Wire EDM processes materials in their hardened state (up to HRC 65+), eliminating dimensional distortion caused by post-machining heat treatment.

Q: What is the standard lead time?

A: Prototypes typically ship within 5-10 business days. Production lead times are confirmed upon order review based on quantity and complexity.

Q: Do you provide inspection reports with shipments?

A: Yes. Standard dimensional inspection sheets accompany every shipment. Full First Article Inspection (FAI) reports or PPAP documentation are available upon request.
