Wire EDM Part Manufacturing in China
Jucheng provides wire EDM machining for custom components. Send your drawing and material requirements for a part-specific review. Our service is the manufacture of parts; we do not sell EDM machines, wire consumables or equipment installation packages.
Wire EDM can be a useful route for a conductive metal component with a through-profile, narrow slot or tooling feature that is difficult to mill. Choosing the process starts with the feature and its acceptance criteria. A tight tolerance on a short accessible profile is a different job from the same tolerance through a thick section or across a tapered wall.
What to Include in Your RFQ
| Information | Why it matters |
|---|---|
| Controlled 2D drawing and CAD file | The drawing establishes units, revision, datums and tolerances; CAD alone may not define acceptance. |
| Material grade, condition and thickness | Conductivity, heat treatment and stock condition affect the process route and dimensional stability. |
| Critical profiles, corner radii and taper | Wire diameter, discharge gap, access and guide geometry constrain the cut. An internal corner is not perfectly sharp. |
| Surface and integrity requirements | Specify roughness where functional, and identify any restriction on the thermally affected surface layer or required subsequent finishing. |
| Quantity and repeat demand | Prototype validation, workholding, inspection and repeat production have different cost requirements. |
| Inspection and delivery requirements | Identify critical characteristics, requested records, delivery destination and required date so the quotation covers the actual scope. |
Feature Review Before Machining
Material and access
Conventional EDM needs an electrically conductive workpiece, as described in Makino's EDM process overview. Ordinary unfilled engineering plastics are not candidates. The wire must also pass through the workpiece: an enclosed profile may require a start hole, while a blind pocket generally calls for a different process.
Tolerance, corners and surface condition
Specify which dimensions control fit or function instead of applying the tightest tolerance to every feature. The proposed cutting passes and inspection method must support those requirements. Do not treat a machine positioning specification as a finished-part guarantee: material stress, setup, thickness and measurement conditions also matter.
For highly loaded or fatigue-sensitive parts, identify surface-integrity requirements at the quoting stage. EDM removes material thermally. Depending on the application, the process plan may need additional passes, subsequent finishing or verification of the affected layer. Those operations should be included in the agreed scope before price and delivery are compared.
Agree on the Complete Manufacturing Route
A wire-cut profile may be only one operation on the drawing. List any milling, turning, heat treatment, grinding or finishing requirements and establish their sequence. A profile that measures correctly before a later operation may move afterward; final inspection should relate to the delivered condition.
For an initial order, agree on a trial quantity and the dimensions to be reported. Approve the drawing revision, material condition and acceptance method together. If a requirement cannot be confirmed during review, resolve it before starting the production batch rather than substituting a general capability statement.
What Determines the Quotation?
Cut length and workpiece thickness influence machining time, but they are not the whole quotation. Start holes, additional passes, difficult workholding, material preparation, inspection and subsequent processes can change both price and lead time. State the required quantity and delivery destination so these costs can be assessed consistently.
Payment terms, shipping arrangements and production dates are established in the project quotation. This page does not promise a universal tolerance, fixed deposit or delivery time for every part. If you are comparing suppliers, use the same drawing package and acceptance criteria for each. Our wire EDM supplier evaluation guide explains how to compare scope and verification evidence.

Use the inquiry form below to share your drawing revision, material, quantity and critical requirements. Include the features that have caused difficulty with other processes. The next step is to confirm the machining route and inspection scope for your part, then establish the quotation and delivery plan.
