Review the drawing first
We flag unclear dimensions, material assumptions and potential manufacturing issues before issuing a quote.
Small-batch manufacturing · Zhejiang, China
Custom fasteners.
Machined to drawing.

drawing-led quoting
Built for hard-to-source parts
A practical supplier for parts that do not fit standard catalogues.
Small quantities, real production
Start with a paid sample or measured trial batch, then scale repeat orders with a consistent process.
Mixed materials and finishes
Stainless, brass, copper and carbon steel parts can be quoted together with the required finish and inspection scope.
Manufacturing base
Rooted in the Diankou hardware ecosystem.
Diankou is a recognised copper and hardware manufacturing cluster in Zhuji, Shaoxing. Its supplier base connects copper processing, precision components, surface finishing and export logistics.

Export supply chain
Diankou is described by the local government as China's Copper Valley and Hardware Town, with a nationally recognised specialty copper precision manufacturing base.
For buyers, the advantage is a deep local supplier network: material supply, machining, tooling, finishing, inspection and logistics can be coordinated around one project instead of being sourced in isolation.
Xinyue is positioned in the Shaoxing-Zhuji manufacturing region and coordinates qualified suppliers based on the drawing, quantity and required process route.
Official Diankou profile · May 2025Regional supply chain
One town, a connected production network.
Copper and metals
Copper tube, rod, profiles, brass and related materials supported by a dense local metals supply chain.
Components and machining
Hardware, fasteners, valves, fittings, machinery and automotive components across a broad base of specialist workshops.
Finishing and logistics
Heat treatment, surface finishing, inspection, packing and port access can be coordinated within the wider regional network.
Production facilities
A wider equipment base behind each quote.
Qualified suppliers are selected according to the drawing and batch. Available routes include:
Regional capability varies by supplier. The exact process route and inspection scope are confirmed before quotation and production.
Product range
Parts shaped around your application.
Send a drawing, sample dimensions or an existing part photo with key measurements. We will tell you what information is missing.
Application examples
Six ways custom parts solve sourcing gaps.
Representative part families for drawing-led quoting. Dimensions, tolerances and inspection requirements are agreed per project.
Capabilities
Quoted around the features that matter.
Every part is reviewed against the drawing, required quantity and destination. The quote can separate material, machining, finish, inspection and packing assumptions so purchasing can compare on the same basis.
- CNC turning, milling, drilling and tapping
- Metric, UNC, UNF, BSP and NPT thread requirements
- Prototype, trial and repeat low-volume batches
- Drawing-led inspection and export packing

Materials and finishes
The right metal for the working environment.
Material grade, corrosion resistance and finish should match the application, not just the drawing.
Stainless steel
304 / 316 options for industrial, food-processing, marine and general corrosion-resistant parts.
Brass
Fittings, threaded components, connectors and parts requiring good machinability.
Copper
Electrical, thermal and fluid-system components where conductivity or material compatibility matters.
Carbon steel
General machinery hardware, brackets, fasteners and parts with specified protective finishes.
Working process
From drawing to delivered parts.
-
01
Share the requirement
Send the drawing, quantity, material, finish and delivery destination.
-
02
Manufacturing review
We check the drawing assumptions and ask focused questions before pricing.
-
03
Sample and approval

-
04
Batch production
Run the approved quantity, inspect the agreed features and prepare export packing.
Good fit
When a drawing is the starting point.
Best suited to buyers who need a practical manufacturing partner for special fasteners, repair parts and low-volume machined components.
Good fit
- Custom or non-standard metal parts
- 20–1,000 piece trial batches
- Stainless, brass, copper and carbon steel
- Hard-to-source replacement hardware
- Industrial, machinery and fluid-system applications
Not a good fit
- Commodity fasteners sold only on lowest price
- Part requests without dimensions or a usable sample
- Automotive safety, medical, aerospace or pressure-vessel parts
- Free prototypes or open credit on a first order
- Parts without an agreed inspection or material standard
