What we make
Seven ways to make a part — and how to choose between them
The right process is usually decided by three things: how tight the tolerance is, how complex the shape is, and how many you need. Every line below says what it is good at and what it costs you relative to the alternatives.
Stamping Parts
Pressed sheet metal brackets, panels and chassis, cut and formed on dedicated tools.
Forging Parts
Shafts, flanges, hubs and gear blanks, forged for grain flow and finish-machined for accuracy.
Casting Parts
Sand-cast housings, valve bodies and frames, machined on the faces that matter.
Die Casting Parts
High-pressure die cast housings and manifolds, with the shape formed in the tool.
Precision Casting Parts
Lost-wax castings in stainless, alloy and bronze, for shapes and tolerances sand casting cannot hold.
Plastic & Injection Parts
Injection-moulded fittings, seals, boots and housings, with the fixings moulded in.
Why buyers move their sourcing here
The same part, made properly, for less
We are not a trading company and we are not a broker. There is a workshop in Nanjing with our name on it, and the people who quote your part are the people who make it.
Lower cost, same spec
Material, energy and labour cost less here, and we do not amortise a regional overhead structure into every part. You are quoted for the same drawing and the same inspection standard at 20–40% below a Western supplier.
Checked three times over
Every part is inspected in process, on final inspection and against the drawing, with a written report issued per batch. The measurement equipment is in the building, not at a third-party laboratory across town.
Engineering, not just production
CAD/CAE/CAM in-house, PDM/ERP/OA across the whole route from design to delivery, and forming simulation before a die is cut. We tell you when a drawing can be made better, and you decide.
A date you can plan around
A sincere date instead of the optimistic one. If tooling is involved, we say how long the tool will take before we quote the part — not after you have committed.
How a part gets from a drawing to your dock
Seven steps, and you know which one we are on
Nothing here is secret, but most suppliers keep it opaque. You get a status against each step, so you never have to chase an order to find out where it is.
Enquiry and drawing review
We read the drawing against the process you have asked for and flag anything that looks expensive or impossible. This is free and it is where most of the value is.
Feasibility and process recommendation
If a different process would be cheaper or better, we say so and show the comparison. You keep the decision.
Quotation
One business day from a drawing we can quote. Unit price, tooling cost, lead time and the payment terms, in writing.
Tooling and first article
New die, mould or pattern is built and a first article is measured against the drawing and approved before the batch runs.
Production
The route is planned and tracked in ERP against the actual capacity of the shop, not a generic calendar.
Inspection and the report
In-process checks, final inspection and the 300% check on critical features, with a dimensional report issued for the batch.
Delivery
Packed to survive the route, with the report and the material certificates in the box. Nothing is left to the last minute.
Flagship process line

Equipment & engineering
The machines are in the building
CNC machining centres and lathes, hydraulic presses, casting and die-casting machines, injection moulding — and the metrology behind them: a coordinate measuring machine, a gear testing machine, a material tester, a hardness tester and a surface roughness tester.
- CAD/CAE/CAM design and forming simulation before a tool is cut
- PDM, ERP and OA across design, production and delivery
- Mill test certificates and material certification with the shipment
- Written inspection report for every batch that leaves the shop
Who buys from us
Parts that go into something bigger
Most of what we make ends up inside a machine that someone else built. These are the industries we ship to most often.

Hydraulics & pneumatics
Manifolds, blocks, unions, adapters and fittings in steel and stainless.
Machine tools
Spindles, shafts, housings, guards and covers for CNC equipment makers.
Material handling
Pulleys, sheaves, rollers, brackets and wear parts for conveyors and lifts.
Pumps & valves
Cased and cast bodies, impellers, flanges and precision valve components.
Energy & process
Heat exchanger parts, pressure parts and corrosion-resistant castings.
Medical & food equipment
Stainless precision castings and machined parts for hygienic process lines.
Automotive & transport
Die-cast housings, stamped brackets and forged drivetrain components.
Before the first drawing
The questions we are asked first
If your question is not here, ask it directly — it is a one-line answer and we would rather you asked than assumed.
What do you need from me to quote a part?
A drawing — a 2D PDF is enough to start, a 3D STEP or IGES file is better because we can check it for manufacturability before quoting. Alongside it we need the material, the quantity and any tolerance that matters more than the rest. If you do not have a drawing yet, send a sample and a sketch of what it does.
Which process should I choose for my part?
If the tolerance is what the part is about, it is CNC machining. If the shape is simple and the volume is high, stamping. If the part carries load and takes shock, forging. If it is a complex shape in cast iron, sand casting. If it is a complex aluminium shape in volume, die casting. If it is small, intricate and in a corrosion-resistant alloy, precision casting. If it is a polymer part, injection moulding. Send the drawing and we will tell you if you are in the wrong place.
How long does a quote take?
One business day for a part we can quote from a drawing. Longer if tooling is involved — a new die or mould needs design and a build before the price can be firm, and we will say so rather than quote a number and move the date later.
Do you work to our drawings only?
Yes. We manufacture against customer drawings and do not substitute materials, change tolerances or redesign a part to suit our production. Where a drawing has a feature we think could be made better, we tell you and you decide.
What minimum order do you take?
One piece for CNC machining — prototypes are a normal part of our work. Stamping, die casting and injection moulding carry a tooling cost, so those only make sense once the volume justifies it, and we will say so plainly when you send the enquiry.
What does "reduce your purchasing cost by 20–40%" actually mean?
It means the same part, made to the same drawing and the same inspection standard, costs less than it does from a supplier in Europe, North America or Japan — because our material, energy and labour costs are lower and we are not amortising a regional overhead structure into every part. It is not a discount on a lesser product.
Send us a drawing
A 2D PDF is enough to start. Tell us the material, the quantity and which tolerance matters most, and you will have a quote in one business day.
