Automotive Sintered Parts — Engine, Transmission & Powertrain
Automotive sintered parts are metal components for vehicles made by compacting alloyed metal powder in a die and sintering it below the melting point — a process that suits high-volume engine, transmission, braking and seating parts at lower cost per piece than machining, with dimensional stability and self-lubricating options. Density and strength values cited here are industry-typical, consistent with our process guide (MPIF-aligned).
We manufacture automotive sintered components inside our own IATF 16949-certified plant — powder blending, pressing, sintering, CNC finishing and Zeiss inspection in one chain, with MES batch traceability for every part number.
5 automotive sintered part families, 20+ part types in one place

Automotive & motorcycle runs in production
It is the actual state we manufacture into every day: pressed, sintered, CNC-finished and inspected in-house — one chain under one IATF 16949-certified roof.
From powder to automotive part, in five steps
The press-and-sinter route we use for every family above — enough to understand cost drivers, tolerances and lead time.
Powder blending
Alloy powder and additives are blended to the target composition for your material spec and density.
Compaction
Powder is pressed in a die on one of 19 PM presses into a raw “green” automotive part.
Sintering
Green parts are heated in 10 controlled-atmosphere furnaces to bond particles into solid metal — at automotive density.
Sizing / CNC
Optional sizing or CNC finishing tightens critical dimensions down to ±0.025 mm.
Inspection & ship
Zeiss CMM, density and hardness testing, MES batch traceability — PPAP/FAI documentation on request.

What we quote against for automotive programs
The numbers automotive engineers actually ask for. Final values are confirmed per part in the DFM review.
| Parameter | Capability | Notes |
|---|---|---|
| Materials | Iron · carbon steel · stainless steel (304L, 316L, 430) | Automotive gear and structural grades; bronze for bushings. |
| Part size | Up to ≈120 mm outer diameter | Largest feature typically ~75 mm; up to ≈120 mm OD depends on press tonnage and geometry — confirmed at DFM. |
| Tolerances | ±0.05 mm standard · ±0.025 mm on selected critical dimensions after sizing & CNC | Not every dimension — only selected critical features hold ±0.025 mm; depends on feature type. |
| Sintered density | Iron 6.6–7.2 · Steel 6.8–7.4 · Stainless 6.9–7.6 g/cm³ | ≈85–92% of theoretical density, consistent with our process guide; exact target locked at DFM. |
| Volume | MOQ 2,000 pcs · pilot batches available | MOQ is the minimum order; 10,000+ pcs/yr is where tooling amortizes best — small trial runs welcome at a different unit price. |
| Quality system | IATF 16949:2016 · ISO 9001:2015 | PPAP · FAI · material certificates · MES batch traceability. |
| Capacity | 3,000+ t/yr · 19 PM presses · 10 furnaces | 10 sintering furnaces including 2 continuous high-volume lines · CNC finishing in-house. |
| Lead time | Tooling ≈30 days · first articles ≈25 days | Quotes and DFM feedback within 48 hours of drawings. |
* Density ranges are typical MPIF press-and-sinter values; exact targets depend on material and application and are confirmed during the DFM review.
** EU shipments: PPWR (EU 2025/40) packaging compliance documentation available on request.
Why automotive buyers route sintered programs here
Automotive-grade quality system
IATF 16949:2016 and ISO 9001:2015. PPAP, FAI and material certificates that pass customer audits — the paperwork is part of the product.
Factory, not trader
Blending, pressing, sintering, finishing and inspection all inside our own 30,000+ m² plants. One chain of custody from powder to pallet.
Sintered gears are our core
