What we make
Machined housings and enclosures
Milled shells, lids and bezels with threads, pockets, sealing grooves and cable exits. One setup where geometry allows.
Shafts, bushings and fittings
Turned parts on 18 lathes and 10 Swiss-type machines, including small-diameter work and parts that need a subspindle.
Manifolds and valve bodies
Air, water and hydraulic manifolds with cross-drilled passages and seal faces checked on the CMM.
Brackets, plates and fixtures
Structural brackets, base plates, test fixtures and assembly jigs in aluminum and stainless.
Knife, EDC and consumer hardware
Scales, liners, clips, spacers and small mechanical assemblies in titanium, G10, carbon fibre and stainless.
Legacy and reverse-engineered parts
No drawing? We measure the sample, model it, and send the drawing for approval before machining.

| Engineering plastics | PEEK, POM, ABS, PC, PTFE, nylon, G10 | Insulators, seals, manifolds, knife scales |
Full material data lives on the materials pages. If your grade is not listed, send the spec — we will confirm before quoting.
Tolerance and inspection
Unmarked dimensions follow ISO 2768-mK. Where the drawing calls for it, we work to ISO 286 IT6–IT8 and hold ±0.002 mm on critical milled features. Every first article is measured on the CMM before the run continues, and the report ships as a PDF. In-process checks use gauges, pin gauges and a height gauge; final inspection is on the CMM.
We do not hold ISO 9001. If your RFQ requires it, we will say so up front rather than waste your time. What we offer instead is a named engineer, a first-article report, material certificates and a written inspection plan.
Finishing, one invoice
Anodising
Type II and Type III, clear, black and colours. Hard anodising for wear surfaces.
Blasting and brushing
Bead blasting, glass bead, sand blasting, brushed and satin finishes.
Polishing and plating
Buff polishing, passivation, zinc/nickel plating, powder coating.
Laser marking
Part numbers, serials, logos and UDI-style marks, quoted with the part.
Why buyers in the US, Europe and Japan use us
- One engineer owns the quote. The person who prices the part is the person who plans how it is made, so the DFM note is real.
- Setup continuity. Prototype fixtures and programs carry into production, so the 500th part matches the first.
- 16-hour quotes. Send before noon; the reply usually lands the next working day.
- No minimum order. Start with one part; scale when the design is proven.
- DDP available. We can quote delivered duty paid so your landed cost is fixed before you order.
FAQ
What is your minimum order quantity?
None. One part is a valid order. Most first orders are 1–50 pieces, and production runs go to 10,000 pieces.
Which materials do you machine?
Aluminum 6061, 7075, 2024 and 5083; stainless 303, 304, 316L and 17-4 PH; titanium Grade 2 and 5; brass, copper; PEEK, POM, ABS, PC, PTFE, nylon and G10. Material certificates are available on request.
What tolerance can you hold?
±0.002 mm on critical milled features, ISO 286 IT6–IT8 fits, and ISO 2768-mK for unmarked dimensions. If a drawing needs something tighter, we say whether we can hold it before quoting.
Do you do finishing?
Yes — anodising, hard anodising, bead blasting, brushing, polishing, passivation, plating, powder coating and laser marking. Most are done by long-term partner plants and quoted as one finished part, one invoice.
Can you work from a sample instead of a drawing?
Yes. We measure the sample, build the model, send the drawing for approval, then machine. This is common for replacement parts and legacy equipment.
How do you protect our design?
NDA on request, no photography without permission, no client names in marketing, and files are accessible only to the engineer and programmer on the job.
Do you ship DDP?
Yes. We quote EXW, FOB Shenzhen/Guangzhou, DAP or DDP. For most US and EU buyers, DDP removes the customs surprise.
