ADVANTAGES OF POWDER METALLURGY PROCESS
· Do not need or only very little machining
· High usage rate of material(more than 95%)
· Parts size consistency is good and stable. The precision can reach 0.01mm.
· The material composition can be adjusted according to the customers’requirement of the parts performance.
· Do the treatment on the surface of the parts according to customers’ requirement to improve the strength and hardness.
· Due to the die forming, we can customize the complex shape or special profiled parts which other machining can not do.
· Because suitable for mass production, the production efficiency is high and the cost is lower than machining.
