This page describes our manufacturing capabilities, quality systems, and the process for working with us as a supplier. If you have drawings and a volume target, request a quotation directly.


What We Make

We produce press-and-sinter PM components in ferrous and non-ferrous materials:

By product type:

  • Gears and gear blanks (spur, helical, face gears)
  • Hubs, flanges, and synchronizer rings
  • Cams, eccentrics, and cam followers
  • Bearing housings and bearing seats
  • Oil pump rotors and gear pump components
  • Structural brackets and mounting components
  • Soft magnetic components (sensor rings, solenoid cores)
  • Oil-impregnated bearings and bushings

By industry:

  • Automotive and commercial vehicle
  • Power tools and hand tools
  • Home appliances
  • Industrial machinery and gearboxes
  • Agricultural equipment
  • HVAC and compressor systems
  • Consumer electronics

See our Applications Overview and Products page for specific part categories.


Manufacturing Capabilities

Press capacity: Multiple hydraulic compaction presses from 6 tonnes to 400 tonnes, supporting part weights from under 5g to approximately 500g.

Sintering: Controlled atmosphere sintering furnaces (hydrogen/nitrogen atmosphere), with logged thermal profiles and temperature control supporting ferrous, stainless, and copper-based materials.

Secondary operations performed in-house:

  • Sizing (secondary compaction for dimensional calibration)
  • CNC turning and milling
  • Tapping and threading
  • Steam treatment
  • Deburring and cleaning

Secondary operations coordinated with qualified partners:

  • Heat treatment (carburizing, quenching and tempering)
  • Surface treatments (zinc phosphate, zinc plating, nickel plating, passivation, electropolishing)
  • Grinding
  • Assembly

See Capabilities and Equipment for a full listing of our production equipment.

How to Work With Us

Step 1: Send Your Inquiry

Provide part drawings (PDF or 3D files), target annual volume, material requirements, and any critical performance specifications. Use the quote request form or contact us directly.

What helps us respond faster:

  • Complete dimensional drawings with tolerances
  • Target annual volume (for tooling cost calculation)
  • Material specification or performance requirement (strength, corrosion, magnetic)
  • Any existing supplier qualification requirements (IATF, PPAP, material certs)

Step 2: DFM Review and Quotation

We review your drawings for PM manufacturability (geometry constraints, tolerance achievability, material selection) and provide a quotation covering:

  • Part unit price at your target volume
  • Tooling investment and ownership terms
  • Sample lead time
  • Production lead time
  • Any recommended design adjustments

Typical quotation turnaround: 3–5 business days for standard parts.

Step 3: Prototype and Approval

After tooling fabrication, first article samples are produced with a full dimensional inspection report. Samples are shipped with material certificates and any requested test data (hardness, density, etc.).

For automotive programs, a PPAP package is prepared before production approval.

Step 4: Production

Production runs are scheduled per agreed delivery terms. Each lot ships with a Certificate of Conformance and batch inspection records. Material certificates and traceability records are maintained per customer requirements.


Frequently Asked Questions

What is the minimum order quantity (MOQ)?

For prototype and first articles: no minimum — tooling is ordered, and samples are produced once tooling is complete. For production: minimum production batch depends on part size and sintering furnace capacity. Typical minimum production batch is 500–2,000 pieces. Annual volumes below 5,000 pieces may have higher per-part costs due to setup frequency; consult us for specific guidance. See our blog post on MOQ and Lead Time for Custom Sintered Parts for more detail.

What is the typical lead time?

Tooling fabrication: 4–8 weeks (depending on complexity) First article samples: 1–2 weeks after tooling completion Production delivery: 3–6 weeks from order confirmation For a full explanation, see What to Send for a PM Quote.

How do you handle tooling ownership?

Tooling is quoted separately from part price. Customers typically own the tooling once it is paid for. Tooling remains at our facility during the active supply relationship and is stored or transferred per written agreement.

Do you support PPAP or supplier qualification?

Yes. We prepare PPAP documentation for automotive customers including dimensional reports, material certifications, process capability studies, and control plans. For non-automotive customers with similar requirements, we can adapt the documentation package to fit your quality system. See PPAP Support for details.

Can you supply directly to overseas customers?

Yes. We ship to customers in Europe, North America, and other regions. Export documentation, commercial invoices, and packing lists are provided per shipment. We work with standard international freight terms (FOB, CIF, EXW) and can coordinate logistics per customer preference.

Is the factory auditable?

Yes. Customers are welcome to visit the facility and conduct supplier audits. We can arrange on-site visits for qualified sourcing inquiries. Contact us in advance to schedule.

What quality certifications do you hold?

IATF 16949:2016 and ISO 9001:2015. Certificate copies are available on request.

Do you have English-speaking engineering and sales support?

Yes. Our team handles technical inquiries, DFM review, and commercial negotiations in English. Response time for initial inquiries is typically within 1 business day.
