Precision CNC Machining & Custom Parts, Made in Shanghai
Founded in Shanghai in 1995. We machine parts to your drawing, build non-standard assemblies, and reverse-engineer imported parts that are no longer available. Milling, turning, gear cutting, sheet metal and heat treatment — all under one roof, all in-house.
ISO 9001-certified · 1 pc minimum · NDA on request · Worldwide shipping
One workshop, from raw stock to finished part
Milling, turning, gear cutting, sheet metal, welding and heat treatment — everything happens in our own workshop, nothing gets outsourced. Send us one drawing instead of juggling several suppliers.
CNC Turning
Horizontal lathes for shafts, bushings, flanges and threaded parts. OD, ID, tapers and threads held to IT6–IT7.
Bevel, Hypoid & Straight Gears
Gear milling and planing for spiral bevel, Zerol, hypoid and straight gears.
Sheet Metal & Welding
Laser cutting up to 6000 × 2500 mm in 0.5–50 mm carbon steel, press-brake bending to 3200 mm, and gas-shielded welding.
Custom Parts & Reverse Engineering
Build to print — or send us the worn part. We measure it, re-draw it and machine a replacement that fits.
Heat Treatment & Finishing
Surface hardening, nitrogen-atmosphere quenching, anodizing, plating and powder coating.
The four things that keep buyers up at night
01
Everything in-house, since 1995
Milling, turning, gear cutting, sheet metal, welding and heat treatment all happen in our own workshop. No subcontracting, no middlemen.
02
A quote in 24 hours
The engineer who will actually run your job reviews your drawing — no hand-offs down a sales chain — so the price and lead time we quote are the ones that hold up.
03
One piece is enough
Prototypes and production share the same machines and the same setups, so part #1 and part #1,000 come out the same.
04
Checked against the drawing
We run an ISO 9001 quality system: every batch is measured against your drawing, records are kept, and a dimensional report can ship with the parts.

How it works
Five steps from drawing to delivery
First-time customers typically receive a sample within two weeks — and at every step you know exactly where your parts are.
01
STEP, STP, IGES, DWG, DXF or a PDF with tolerances. Add quantity, material and finish.
02
We review your design for manufacturability and cost, then send price and lead time — within 24 hours.
03
We machine and measure one part before the batch starts. Photos and a dimensional report on request.
04
Same machines, same process, in-process inspection, and a progress update every week.
05
Final inspection, rust-proof packing, then DHL / FedEx / UPS — or your own forwarder.
