The stainless steel parts manufacturer you choose decides your quality, your cost, and your lead time. The wrong partner means material waste, rework, and missed deadlines. The right partner delivers consistent quality, honest schedules, and engineering input that actually lowers your cost per part.

Xinjiuxinji Hardware has been a custom stainless steel parts manufacturer since 1999. We are based in Nanpi County, Hebei, China — the country’s hardware manufacturing heartland, close to Beijing and Tianjin.

To date, we have produced more than 70,000 types of custom metal parts, with 85% of our output exported, mainly to North America, Europe, and Oceania. Stamping, deep drawing, laser cutting, bending, welding, and finishing all run in-house under one ISO 9001:2015 certified roof. No subcontracting, no handoffs.

Stainless Steel Grades We Work With

Stainless steel resists corrosion, heat, and chemicals because its chromium content — above 10.5% — forms a self-healing oxide layer. That is why it dominates in food processing, medical devices, marine hardware, and outdoor equipment.

• Grade 304 — the general-purpose workhorse. Balanced corrosion resistance and formability. Ideal for enclosures, brackets, panels, kitchen equipment, and most indoor or light outdoor use.
• Grade 316 — molybdenum adds stronger resistance to chlorides and saltwater. The right choice for marine, chemical, and coastal applications.
• We also work with 201, 430, 409, and other grades.

Our engineers review material selection with you before any tooling is made, so you get the right grade for the environment — and the right price.

Our Manufacturing Capabilities

Every core process is in-house. That is how we control quality, cost, and lead time:

• Stamping — 40+ presses from 60T to 400T, including a 400T single-point press for large parts. Progressive and transfer tooling for high-volume runs.
• Deep drawing — our specialty. Seamless, one-piece housings, enclosures, cups, and vessels, drawn with consistent wall thickness on the 400T press.
• Laser cutting — 6kW machines for clean, burr-minimized edges; fast turnaround for prototypes and batches alike.
• Bending & forming — CNC-controlled press brakes for accurate angles and consistent dimensions across large runs.
• Welding — CNC-controlled welding for repeatable, clean welds, including thin-gauge stainless where distortion control matters.
• Machining & finishing — drilling, grinding, spinning, and CNC machining, plus in-house brushing, polishing, and passivation.

From Drawing to Delivery

1. Design review — our engineers check your drawings within 1 working day and suggest forming or material changes that cut cost and improve manufacturability.
2. Prototyping — new parts are sampled first, so you can validate fit, function, and finish before committing to production.
3. Production — approved samples move to our in-house machines, with full process documentation.
4. Quality inspection — every batch is checked for dimensions and surface quality against your drawings and agreed standards.
5. Packaging & delivery — parts are packed to export standards, with export documentation handled in-house.

Because everything runs inside one factory, changes, rework, and urgent orders are handled directly — not relayed through agents or third-party workshops.

Industries We Serve

Aerospace, automotive, construction tools, electronics, energy, medical & healthcare, metal hardware, home & garden, farming equipment, fire-fighting equipment, packaging machinery, and marine & shipbuilding.

How We Control Quality

Quality is controlled at every step of production, not just checked at the end. On every order, our in-house team performs:

• Incoming material verification against mill certificates
• First-article inspection before production runs
• In-process dimensional checks during stamping and forming
• Final inspection, including surface quality and packaging

Inspection reports are available on request to support your own incoming QC — all under our ISO 9001:2015 certified system.

Why Choose Us as Your Stainless Steel Parts Manufacturer

Any factory can stamp or cut metal. What makes a manufacturer worth trusting is consistency — order after order, part after part. Here is what we bring:

• Track record — 70,000+ custom metal parts since 1999, across dozens of industries.
• Export experience — 85% of output shipped overseas, mainly to the US, Germany, the UK, France, Ireland, Australia, and New Zealand. We know export documentation, packaging standards, and the quality expectations of demanding Western buyers.
• In-house capability — 40+ presses, 5kW laser cutting, CNC welding, and full finishing under one roof.
• Engineering support — 120 employees, including 19 engineers, who review your designs before production — not after problems appear.
• Straight talk — we review drawings, verify samples, and commit only to schedules we can keep. No empty promises.

FAQ

What stainless steel grades can you work with?

–304, 316, 201, 430, 409, and more. Our engineers help you choose the right grade for the environment and your budget.

Can you prototype before mass production?

–Yes. Prototyping is standard for new parts. Laser cutting and small-batch lines get samples to you quickly, so you can validate fit and finish before production tooling is committed.

What is your MOQ?

–It depends on the process and part size. Because tooling is made in-house, we can start small and scale efficiently as your demand grows. Send drawings for a specific answer.

Do you offer surface finishing?

–Yes — brushing, polishing, and passivation are done in-house, so parts arrive ready for use or assembly.

How do you keep quality consistent on large orders?

–ISO 9001:2015 procedures: first-article inspection, in-process checks, and final inspection on every batch. Acceptance criteria are agreed in writing before production starts.
