Xinjiuxinji supplies custom stainless steel parts to OEMs and importers worldwide. Our production base in Nanpi, Hebei — China’s hardware manufacturing hub — has been manufacturing metal parts since 1999.
Stamping, deep drawing, laser cutting, bending, welding, CNC machining and surface finishing all run under one roof and one ISO 9001:2015 system, so nothing in your order is outsourced. Our Nanpi production base employs 120+ people, including 19 engineers, and has completed more than 70,000 full-process custom projects.
Customers across the US, Germany, the UK, France, Ireland, Australia, New Zealand, Thailand, India, Singapore and Saudi Arabia. Every order ships with English engineering support, full export documents and inspection reports.

Stamping & deep drawing
40 presses, 80–400 t; progressive dies for high-volume runs; seamless housings, cups and enclosures.
Laser cutting & bending
2 × 6 kW laser cutters; CNC bending machines for accurate angles; thin sheet to plate.
Welding & assembly
3 welding lines plus automatic spot welding; jigs and fixtures keep assemblies repeatable.
CNC machining
2 five-axis machining centers and 3 vertical machining centers for features forming cannot produce.
Surface finishing
2 in-house lines: acid wash, passivation, electrolytic polishing, spraying and oxidation.
Inspection & traceability
2 CMMs, spectrometer, roughness and hardness gauges, salt-spray testing; batch records kept per order.
Every project runs as a single production chain — one partner, one responsible team, from drawing to delivery. Parts we ship are used in medical equipment, electronics, automotive, energy, construction tools, home & garden, agricultural machinery, packaging, and marine and offshore applications; multi-process assemblies are where we add the most value.
Stainless steel grades we work with
Engineers review function, service environment and cost target before recommending a grade — this decision is where most corrosion risk and material cost is won or lost.
Beyond stainless we also fabricate carbon and galvanized steel (SPCC/DC01, Q235, SECC, DX51D), aluminium (5052, 6061), copper and brass (C1100, C2600), and casting alloys to your drawing.
Project case

FAQ
What stainless steel grades can you fabricate?+
304/304L, 316/316L, 430 and 201 as standard, in both sheet and formed parts. Other grades are reviewed on request.
Can you help choose the grade?+
Yes. Grade selection is part of our free design-optimization service. We look at the service environment, load and finishing requirement, and recommend the most cost-effective option.
What do you need to quote a stainless steel part?+
Drawings, material or grade if already fixed, order quantity, surface finish, and the market the part ships to. We answer with a price and DFM feedback within 8 hours.
Do you handle both small batches and high volume?+
Yes. Tooling and process route are set according to annual volume, so low-volume first orders and high-volume repeat runs both make sense.
