Powder Metallurgy Sintered Filters
Sintered PM filters for consistent, high-performance gas and liquid filtration — precise pore size control, high mechanical integrity and superior thermal resistance versus welded mesh filters.
- Materials
- Stainless steel, bronze and Fe-based sintered powders
- Features
- Precisely controlled porosity, high strength under pressure and thermal cycling, custom shapes and pore distributions, back-flushable and reusable, near-net-shape production
- Application
- Industrial gas filtration (compressed air, exhaust), chemical processing fluid separation, automotive fuel and oil filtration, aerospace fluid and gas management, laboratory and analytical equipment.
Frequently Asked Questions
What materials and process are used for Powder Metallurgy Sintered Filters?
Powder Metallurgy Sintered Filters is made from Stainless steel, bronze and Fe-based sintered powders and is formed by MIM/PM (metal injection molding / powder metallurgy) near-net-shape and sintered to a relative density of ≥ 98%, which keeps mechanical properties close to wrought material.
What tolerances can Powder Metallurgy Sintered Filters hold?
Typical as-sintered dimensional tolerance is ±0.3–0.5% of the dimension. Tighter tolerances are achievable with secondary sizing or machining, agreed per part during quoting.
What is the MOQ and lead time for Powder Metallurgy Sintered Filters?
MOQ is 1000 pcs. Mold lead time is about 20 days (mold fee typically RMB 20–40k depending on part geometry), and production lead time is about 7 days once the mold is validated; secondary processing adds 3–5 days.
