The self-lubricating effect depends on material porosity and lubricant impregnation volume. Under typical design and normal usage conditions, it can maintain stable low-friction performance over the long term; actual service life should be evaluated based on operating frequency, load, and environmental conditions.
Through precision compaction molds and controlled sintering processes, PM nozzles can consistently achieve micron-level bore tolerance uniformity, ensuring mass-production stability in fluid spray angle and flow rate.
Powder metallurgy is suited for medium-to-large, relatively simple structural parts, offering cost advantages, precision within 0.3% ; MIM is better suited for micro-sized parts with complex geometries, precision about 1-3%. The actual choice should be comprehensively evaluated based on part size, complexity, and production volume.
Foldable phone hinges must withstand hundreds of thousands of open-close test cycles. Powder metallurgy combined with subsequent heat treatment effectively improves fatigue strength and wear resistance, making it one of the mainstream processes for foldable-phone hinge structures today.
No. Powder metallurgy can optimize material formulation and structural design to produce lightweight, dimensionally stable metal parts that meet the thin-and-light design requirements of 3C electronics, while maintaining material utilization rates above 98%.
Powder metallurgy can use SS-316 and SS-304 materials, both of which are more than twice as strong as zinc-aluminum alloys.
