Small-batch manufacturing · 1–2,000 pieces

Built for the batch nobody else will run.

A small shop in Zhejiang for hardware teams stuck between prototype and production: magnets, technical ceramics, carbide and precision plastics, one to two thousand pieces. Send a drawing and the reply is about fit, price and date — or an honest no in the first line.

Dates count from drawing sign-off with material in stock. Ceramics wait on the sintering run and hold ±0.05 mm after grinding; carbide and multi-process builds run longer. Every date is confirmed per part on the quote — this row is a shape, not a promise.

What arrives before you pay for a batch.

A website can claim anything. What you can actually check is a measurement taken on a part that exists, and the documents that travel with it. Those are the two things this shop puts on paper.

In the parcel and in the inbox

First-article report: Issued before the batch runs, not with it. You approve it first.
Dimensional report: Every dimension your drawing marks as critical, measured and recorded.
Material certificate: For the lot actually used, with its heat or batch number.
Reading log: The raw values in production order, so you see the spread instead of taking our word for it.

How a batch is checked →

About every photograph on this site. They are illustrations. Customer parts cannot be published, and a stock photo of somebody else's shop floor would be a worse lie than an honest drawing. What we can give you is a part measured with real numbers on it, a redacted report from a real batch, and a camera pointed at the machine that would run your job.

What we make, and where it stops.

Factories quote 500–1,000 piece minimums, and a local job shop can charge $300–2,000 for a single part. Between those two prices sits the work this shop is set up for: too small for a production line, too expensive to hand-make. A drawing is not always required either — a dimensioned sketch or a marked-up photo is enough to quote a first article against.

Sintered NdFeB magnets: arc segments, ring, block and cylinder

01 / Magnetics

Custom magnets

NdFeB, SmCo and ferrite. Arc, tile, ring, trapezoid and multi-pole magnetized parts, cut from standard blanks.

N35–N52 · H / SH / UH

Zirconia rings, alumina disc and silicon nitride plate

02 / Ceramics

Technical ceramics

Zirconia, alumina and silicon nitride, green-machined before sintering so no mold is needed. Setup, wheel dressing and fixture time are still quoted — "no mold" is not the same as "no tooling". Electronic ceramics

3Y-TZP · 96–99.5% Al₂O₃

Tungsten carbide insert, punch, die and seal ring

03 / Carbide

Carbide parts

Non-standard inserts, punches, dies, nozzles, seal rings and form tools.

WC-Co · TiC-steel

Machined POM gears, PEEK bushing and PTFE seal ring

04 / Polymers

Precision plastics

CNC plastics, and injection molding from 100 pieces on an aluminium tool — the tool is a separate line on the quote, never folded into the part price.

Materials & tolerances.

These are the site standard — the tolerance a feature gets when your drawing does not single it out. A specific callout is answered against the specific feature, not against a table.

Item	Site standard
Metal	±0.02 mm
Ceramic	±0.05 mm after finish grinding
Magnets	±0.05 mm wire-cut · ±0.01 mm ground
Accepted files	STEP, IGES, DXF, STL, or a PDF drawing
Finishing	NiCuNi, epoxy, zinc, passivation, anodizing, bead blasting
Process	Drawing review → quote → first article → small batch

Tolerance is confirmed per feature, not per material. A 0.8 mm wall, a deep pocket, a 0.3 mm edge radius or a large flat face each move the number in a different direction — size, geometry and process change what is achievable, so a part is quoted against its own hardest feature. If your callout is tighter than the process holds, that is said in the quote, before you commit to anything.

From a drawing to a batch, in six steps.

No shopping cart, no minimum order value, and no "request a quote" button that vanishes into a CRM. This is the whole route, including where money changes hands — because that is the part buyers get surprised by.

Send the requirementA drawing, a dimensioned sketch, or a plain description. Email, the form, or WeChat.
Technical checkWhether it can be made, in what material, and which feature is the hard one.
Formal quotePrice, lead time, tooling and setup as separate lines. Two working days.
Paid first articleOne or a few parts, measured and reported, before any batch commitment.
You accept itYou hold the part. If it is wrong, this is the cheapest place to find out.
Small batch runsReleased only on your written approval, at the price already quoted.

What the first article contains

The part itself, its dimensional report, photographs of the critical features, and the material certificate for the lot. It is a purchase you can inspect and refuse, not a free sample that arrives with a sales call.

What you pay for, and when

The first article is paid before it is made, because by then the material and the setup are already spent. Tooling, programming and setup are their own lines on the quote. Nothing else is charged until you approve.

What happens if it fails

Out of tolerance at final inspection: you hear it before the shipment leaves, with the measurement and a photograph, and you choose — rework or remake at our cost with a new date, or ship as-is at a reduced price.

What is yours

The drawing you send, the model built from it, and any tooling made against your order. We keep copies only for the retention period, and delete them on request.

The shop behind the quote.

You are being asked to send drawings and money to a company you have never visited. These are the things worth checking before you do — and they are all checkable.

Where: Taizhou, Zhejiang, China. The address on the invoice, the packing list and the parcel label is the same address.
Who: Benny, Sales Manager. One person reads the enquiry — not a shared inbox and not a form router.
See it: Ask for fifteen minutes and we hold the camera on the floor. More about the shop →
Run here: Machining, assembly, dimensional inspection and packing.
Sent out: Sintering at the ceramics plants; plating and coating at two finishing shops we have used for years; standard blanks from the mills. Named on the quote, as their own line.

The five questions that decide a first order.

Answered here so the first email can be about the part.

What does a first order actually cost?

The first article, plus tooling or setup if the part needs it. Both are separate lines on the quote — never folded into a per-piece price and revealed later. If you want one number you can have it, but then you cannot see what you paid for the tool.

How long does it really take?

Metal and plastics run 7–12 days to a first article, counted from drawing sign-off with material in stock. Ceramics wait on the sintering run. Whatever the number is, it is on the quote with its start point written next to it — and if the date moves, you hear it the day it moves.

Who sees my drawing?

Quoting, programming and inspection — not the whole floor. Files sit on a controlled drive rather than being passed around by chat. We sign your NDA or send ours, and files are deleted when you ask. The four commitments →

Who pays the duty, and when do I pay you?

DAP by default: you are the importer of record and pay duty through your broker, while our invoice covers parts and freight. DDP is available on request as one landed price. Payment is a deposit on order and the balance before shipment. Full terms →

What if the parts are wrong?

Critical dimension out at final inspection: you hear it before the shipment leaves, with the measurement and a photograph, and you choose — rework or remake at our cost, or ship as-is at a reduced price. If a defect turns up after delivery, tell us the piece count and the failure mode; we decide within one reply and replace or credit.

Send the drawing. Get a price and a date.

Tell us the material, the quantity and the date you need it. A dimensioned sketch or a marked-up photo works if a formal drawing does not exist yet. What comes back is a fit review, a price and a ship date — with the start point of that date written next to it.
