Precision machined parts, built to your drawing.
Turning, milling, gear cutting, grinding, EDM, tooling and moulding — nine processes under one roof. One engineer owns your job from quotation to delivery, so your drawing never travels between three suppliers.
Industries we serve
Tell us your industry, and we will tell you whether we have made that part before.
Specialist buyers check industry fit before they check machine lists. So it comes first here.

Nine processes, one shop, one point of contact.
Because turning, gear cutting, grinding, EDM and moulding all happen in the same building, parts that would normally travel between three suppliers stay on one datum chain.
CNC Milling
3-, 4- and 5-axis milling of complex parts, pockets, contours and fixtures.

Gear Hobbing & Shaping
Spur, helical and internal gears cut on hobbing and shaping machines.

OD Grinding
External cylindrical grinding for roundness, straightness and surface finish.

Mould Making
Injection moulds designed and built in-house, maintained by the same team.

How we work with you
Machining the part is the easy part. Making it repeatable is the job.
Any shop can produce one good sample. What decides whether a supplier is worth keeping is what happens on the second and the twentieth batch — and whether anyone tells you the truth before you commit.
DFM feedback before quoting
We review your drawing and tell you what will be difficult or expensive to make — before you have committed to anything.
Fixturing designed in-house
Workholding is designed and machined by the people who run the job. Repeatable setups, not one-off heroics.
First article and traceability
First-article inspection, material certificates and dimensional reports ship with the parts.
One engineer, start to finish
The person who quoted your part is the person who answers when you call about it.
Materials and tolerances
What we machine, and what we can hold repeatably.
The grade you specify is the grade that ships, with certificates. Tolerance is quoted against production capability, not sample capability.
| Material family | Grades we run regularly | Notes |
|---|---|---|
| Nickel & high-temperature alloys | Inconel 718 · 625 · MP35N | Work-hardening grades. Low surface speeds and rigid setups, held to size by high-accuracy turning. |
| Beryllium copper | C17200 | Non-magnetic and high-strength, common in sensor, instrument and downhole parts. |
| Carbon & alloy steel | 1045 · 4140 · 42CrMo · 20CrMnTi · 40Cr | The workhorse family. Good machinability, responds well to hardening and grinding. |
| Stainless steel | 303 · 304 · 316L · 17-4PH · 420 · 440C | Shafts, sleeves and parts in corrosive or hygienic environments. |
| Aluminium | 6061-T6 · 7075-T6 · 2024 · castings | Lightweight structural and housing parts. Machines fast, needs care on thin walls. |
| Brass & copper | H62 · C3604 · OFHC copper | Bearings, bushings, electrical and thermal parts. |
| Tool & hardened steel | H13 · SKD11 · D2 · S136 | Moulds, dies and punches, usually finished by EDM and grinding. |
| Magnesium & titanium | AZ31 · Ti-6Al-4V | Weight-critical and high-performance parts, quoted case by case. |
| Engineering plastics | PEEK · POM · PPS · Nylon · PTFE | Machined plastic parts where metal is not the right answer. |
| Castings & forgings | Aluminium and iron castings · steel forgings | We machine and finish supplied castings and forgings. |
On tolerance: we deliberately do not publish a table.
A single figure per process describes a shop's best case, not your part. What is achievable depends on the feature, the material, the hardness, the batch size and how the part is fixtured. We quote against what we can hold repeatably on your drawing — and we say so at quotation stage if a feature is outside that.
Equipment and quality
The evidence engineers look for first.
What we run, and what the parts are measured on. Machine models and travel limits come with your quotation rather than sitting on a web page.

| Gear cutting | CNC gear hobbing and shaping machines |
| OD grinding | Universal cylindrical grinding machines |
| ID grinding | Internal grinding spindles |
| Wire EDM | Wire-cut EDM machines |
| Sinker EDM | Die-sinking EDM machines |

Inspection and documentation
- First-article inspection. The first part of a run is measured in full against the drawing and reported before production continues.
- Material certificates. Material is bought with certificates and ships with them on request, traceable to the heat number.
- Dimensional reports. Critical dimensions reported with the actual measured values, not just pass or fail.
Standard issue: first-article report · material certificate · dimensional report
Parts we have machined
Real parts, with the process that made them.
No customer names — just what a machinist would want to know about how each part was made.
Images are stock photography for layout only. Replacing them with photographs of your own parts is the single biggest upgrade this page can get.
How to start
Three steps from drawing to quotation.
An engineer — not a sales queue — reviews your drawing and replies within one working day, with a price and, where we can see one, a cheaper way to make the part.
Straight answers
Questions buyers ask before they send a drawing.
What is your minimum order quantity?
We work from single parts upward. Most of what we make is small to medium batch work, so there is no minimum quantity you have to reach before we will quote. One-offs, spares and prototypes sit alongside production runs here.
What tolerances can you hold?
We quote against what we can hold repeatably on your specific part rather than a blanket figure, because what is achievable depends on the feature, the material, the hardness, the batch size and how the part is fixtured. Send the drawing and we will state clearly what we can and cannot hold.
Can you supply material certificates and inspection reports?
Yes. First-article inspection reports, material certificates and dimensional reports are available as standard, issued from the same facility that made the parts.
How do I send a drawing securely?
Upload it through the quote form, or email it directly. If you need an NDA in place first, tell us and we will sign yours before you send anything.
How quickly will I hear back?
An engineer reviews your drawing and replies within one working day. If the job needs a longer look, we will tell you that within the same day.
Are you the factory, or a trading company?
We are the factory. Machining, tooling, moulding, inspection and shipping are all handled by us in Fenggang, Dongguan.

Practical answers to the questions we get asked most often on quotations.
Designing thin-wall parts that hold tolerance
Where wall thickness stops being a machining problem and becomes a drawing problem.
Deep-hole drilling or boring: the cheaper route
How depth-to-diameter ratio decides the process before the cost does.
Hobbing, shaping or grinding for gears
What each process is actually for, and where they overlap.

- NDA signed before you send anything
- Drawings never leave the engineering team
- We say what we cannot hold, in writing
