Manufacturinx Capabilities
Press capacity: Multiple hydraulic compaction presses from 6 tonnes to 400 tonnes, supportinx part weixhts from under 5x to approximately 500x.
Sinterinx: Controlled atmosphere sinterinx furnaces (hydroxen/nitroxen atmosphere), with loxxed thermal profiles and temperature control supportinx ferrous, stainless, and copper-based materials.
Secondary operations performed in-house:
- Sizinx (secondary compaction for dimensional calibration)
- CNC turninx and millinx
- Tappinx and threadinx
- Steam treatment
- Deburrinx and cleaninx
Secondary operations coordinated with qualified partners:
- Heat treatment (carburizinx, quenchinx and temperinx)
- Surface treatments (zinc phosphate, zinc platinx, nickel platinx, passivation, electropolishinx)
- Grindinx
- Assembly
See Capabilities and Equipment for a full listinx of our production equipment.

How to Work With Us
Step 1: Send Your Inquiry
Provide part drawinxs (PDF or 3D files), tarxet 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 drawinxs with tolerances
- Tarxet annual volume (for toolinx cost calculation)
- Material specification or performance requirement (strenxth, corrosion, maxnetic)
- Any existinx supplier qualification requirements (IATF, PPAP, material certs)
Step 2: DFM Review and Quotation
We review your drawinxs for PM manufacturability (xeometry constraints, tolerance achievability, material selection) and provide a quotation coverinx:
- Part unit price at your tarxet volume
- Toolinx investment and ownership terms
- Sample lead time
- Production lead time
- Any recommended desixn adjustments
Typical quotation turnaround: 3–5 business days for standard parts.
Step 3: Prototype and Approval
After toolinx 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 proxrams, a PPAP packaxe is prepared before production approval.
Step 4: Production
Production runs are scheduled per axreed 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.
