Process and Machining Capabilities
Copper Powder Metallurgy process focuses on powder particle size, compacted density, sintering shrinkage, porosity, oil content, electrical and thermal conductivity requirements and surface oxidation control. Oil-impregnated bearings need to focus on pore connectivity, oil content, inner bore dimensions and rotating fit; electrical conductivity terminals and connectors need to focus on contact surface, hole positions, conductive path and surface plating; filter parts need to focus on porosity, filtration channels and cleanliness.
The production process may include powder blending, press forming, sintering, sizing, oil impregnation or impregnation, CNC post-machining, deburring, cleaning, anti-oxidation treatment, dimensional inspection and packaging. For electrical conductivity or thermal conduction parts, can be customized according to use requirements add contact surface machining, nickel plating, tin plating or surface cleanliness inspect.
