Custom CNC Machining · Tongyong Industries
Tongyong Industries provides custom CNC machining services for global B2B projects. We produce milled, turned, 5-axis and wire EDM metal parts to confirmed drawings—from prototypes and low-volume runs to repeat production.

Great products often start as one prototype on a startup's bench. Low quantities are not a problem here — we welcome early-stage teams and growing brands and provide engineering support throughout development. As volumes rise, confirmed processes help support a smoother transition to repeat production. Our goal is to support every stage of your product development.
Even a single part is welcome — prove the design first.
Tested parts and DFM feedback that de-risk the next step.
Small batches that confirm a stable, repeatable process.
Repeatable production with consistent quality and agreed delivery schedules.
Integrated support for CNC milling, turning, 5-axis machining, micromachining and EDM—from prototypes to repeat production.
3-axis milling for enclosures, brackets, plates and heat sinks, held to tight dimensional and surface tolerances. Ideal for housings and structural parts.
Precision turned shafts, sleeves, pins, threads and connectors with controlled diameter, length and surface finish — the foundation for transmission and fastening parts.
Multi-face, multi-angle geometries machined in a single setup — complex contours with fewer fixtures, fewer re-clamps and higher repeatability across batches.
High-precision CNC micromachining for miniature metal parts requiring fine features and tight tolerances.
Sharp corners, narrow slots, hardened metals and complex profiles that conventional cutting can't reach — accurate contours with low distortion.
Coordinate anodizing, polishing, bead blasting and other finishing processes to improve part appearance, surface performance and functional requirements.
01 - Custom
Every part is made to your drawing — your material, tolerance, finish and quantity. No catalogue limits and no forced standard parts.
02 - Quality
Material checks, in-process inspection and final dimensional verification help confirm parts meet the agreed requirements.
03 - Support
Questions are addressed early, requirements stay aligned, and project details are tracked from drawing review through delivery.
Not sure which alloy fits? Tell us the application and our engineers recommend a grade during DFM review, balancing strength, weight, corrosion resistance, machinability and cost.
| Preview | Finish | What it does |
|---|---|---|
|
As-machined | The default finish straight off the machine, typically Ra 1.6–3.2 µm with light visible tool marks. |
|
Anodizing | Type II and hard-coat anodizing create a protective oxide layer on aluminium for corrosion resistance, wear resistance and color. |
|
Polishing | Mechanical polishing reduces roughness to a bright, smooth or mirror surface for cosmetic and high-spec parts. |
|
Bead / sand blasting | Blasting media give a uniform matte texture, removing tool marks and evening the surface before or after coating. |
|
Tumbling / deburring | Vibratory tumbling deburrs and smooths small parts in bulk, rounding sharp edges and evening the surface. |
Our engineers analyze your drawing for process and feasibility, then confirm the machining plan and quote.
Parts are machined to the confirmed plan, with the whole process monitored for accuracy and efficiency.
Finished parts are checked across multiple dimensions to confirm size, finish and performance meet spec.
Approved parts are packed and shipped with tracking, so your order reaches you on time and intact.

Why a single blanket tolerance is the wrong way to spec a part, and how confirming critical dimensions at DFM keeps quality high and cost sensible.
Common questions
A 3D model (STEP or IGES) is ideal, along with a 2D drawing (PDF or DWG) for critical dimensions, tolerances and finish. A sketch with a short description is enough to start the conversation.
Yes. We work from a single prototype and welcome early-stage teams and new products. Low volumes are fine, and the same setup carries forward as you scale.
Our engineering team will review your drawings and provide initial feedback based on project requirements and manufacturing feasibility.
Manufacturing is carried out through Shantou Tongyong Hardware Industrial Co., Ltd. (Tongyong Hardware) at a 15,000 m² manufacturing center in Shantou, China — the certified manufacturing entity within the Tongyong business system — supported by global supply-chain coordination. Tongyong Industries (Singapore) is the contracting entity and international business contact point.
We confirm general and specific tolerances against your drawing during DFM review. Tighter tolerances on capable features are agreed up front, with measurement and an inspection report available on request.
