As far as we known,the household appliance industry in domestic China has been developed smoothly and the quality of home-appliance and its material has beome more and more important,especially the powder metallurgy technology that used on household appliance has attracted more and more household appliance manufacturers.
Many household appliance material and household parts could only be produced by powder metallurgy,such as the refrigerator compressor,washing machine,electric fan and other porous self-lubricating bearings,and for some household appliance spare parts,if they could be finished by powder metallurgy process,the quality would be much better while the cost would be much lower,such as the gears used on air-conditioning fan and dust cleaner,both of them could be produced by powder metallurgy,as it would bring much benefit for the manufacturers.What's more,powder metallurgy always play an important role on environmental protection and energe saving.
Powder metallurgy process almost is no smoke and chemical pollution, and it is near final forming and no or less cutting processing,at the same time almost no waste loss.What'more,the weight of powder metallurgy parts always is very light and the material utilization rate is the best.As some analysis report showed,for one spare parts,if we use powder metallurgy to finish not traditional process,the procuce cost could be declined 75% and the efficience would be increased 1.7 times.Thus innovating and applying powder metallurgy material is a inevitable trend.
