Sintered Industrial Parts — Factory-Direct PM Components for 12 Machine Categories
Sintered industrial parts are metal components for industrial machinery made by compacting alloyed metal powder in a die and sintering it below the melting point. We manufacture the full range inside our own IATF 16949 plant — powder blending, pressing, sintering, CNC finishing and Zeiss inspection in one chain, with MES batch traceability for every part number.
This page groups our PM industrial components by the four machine systems they go into: mechanical drive, fluid power, automation, and industrial machinery. Send the drawing, and we confirm material, density and price within 48 hours.
It is a metal component for industrial machinery — gears, sprockets, pump rotors, valve seats, robot joints, conveyor parts, printer and copier gears — produced by pressing alloyed metal powder in a die at 400 to 800 MPa and sintering it in a controlled-atmosphere furnace at 1120 to 1150 °C. The shape comes from the die in one stroke, the strength comes from the furnace, and the cost comes from the volume the tooling amortizes across. Density and strength values cited on this page are industry-typical, consistent with our press-and-sinter process guide (MPIF-aligned).

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.
How It Works
From powder to industrial part, in five steps. The press-and-sinter route we use for every family above — enough to understand cost drivers, tolerances and lead time before you commit to tooling.
- 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 green industrial part at 400 to 800 MPa.
- Sintering — Green parts are heated in 10 controlled-atmosphere furnaces at 1120 to 1150 °C to bond particles into solid metal.
- 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 don’t do well
Honesty is cheaper than rework. Sintering is the wrong tool for:
- Production volumes below ~10,000 pieces per year — tooling does not amortize at that scale; machining usually wins.
- Parts beyond 1,000-tonne press capacity (very large housings or frame components) — those route to casting or forging.
- Thin walls under MPIF minimums or massive section changes — design rules on our wall thickness page.
- Applications needing 98%+ density and fatigue life beyond what infiltration can buy — MIM, powder forging or wrought material fit better.
- Tight surface-critical seal faces without secondary sizing — typically under 0.4 µm Ra — those route to machining or grinding instead.

What are sintered industrial parts, and what machines use them?
Sintered industrial parts are metal components for industrial machinery made by compacting alloyed metal powder in a die and sintering it below the melting point. They appear in mechanical drive (gears, sprockets, conveyor parts), fluid power (pump rotors, valve seats, hydraulic and pneumatic components), automation (robot joints, packaging machine parts, printer and copier gears), and industrial machinery (textile, agricultural, sewing, lawn-mower parts). Density and strength values cited here are industry-typical, consistent with our process guide (MPIF-aligned).
Why is powder metallurgy a good fit for industrial component production?
PM fits industrial programs where the part runs in volume, the geometry repeats, and the duty fits 85 to 92% density. Material utilization of 97%+ versus 30 to 60% for machining cuts scrap cost, and the die generates the shape in one press stroke, so per-part labor and cutting time are minimal. The trade-off is the upfront tooling cost, which is why PM typically wins above 10,000+ parts per year and loses below it.
Which industrial applications should not use sintered parts?
Sintering is the wrong tool when production volume is below ~10,000 pieces per year (tooling does not amortize), the part exceeds 1,000-tonne press capacity (very large housings), or the duty requires 98%+ density and fatigue life beyond what infiltration can buy. Parts needing a tight surface-critical seal without secondary sizing — typically under 0.4 um Ra — usually route to machining or grinding instead.
What tolerances and density do you hold on sintered industrial parts?
As-sintered tolerance is typically ±0.05 mm. Sizing tightens selected critical dimensions to ±0.025 mm. Iron-base density lands at 6.6 to 7.2 g/cm3 (85 to 92% of theoretical), with stainless at 6.9 to 7.6 g/cm3. Final targets are confirmed per part during the DFM review based on material, geometry and duty.
What is the MOQ and lead time for sintered industrial parts?
MOQ starts at 2,000 pieces; pilot batches are available at a different unit price. Tooling takes about 30 days, first articles around 25 days, and quotes plus DFM feedback come back within 48 hours of receiving the drawing. Annual capacity is 3,000+ tons across 19 PM presses and 10 sintering furnaces.
Do you provide PPAP and quality documentation for industrial programs?
Yes. We hold IATF 16949:2016 and ISO 9001:2015. PPAP, FAI, material certificates and MES batch traceability are standard. For EU shipments, PPWR (EU 2025/40) packaging compliance documentation is available on request. The paperwork is treated as part of the product.
