Powder metallurgy materials for household appliances

Many household appliances will now used in powder metallurgy process to make, take the common electric fan, refrigerators, computers, air conditioning, but also with respect to the traditional process, used in powder metallurgy price and cost far below the traditional process, today Xiaobian accompany you to understand household appliances in powder metallurgy materials together!

In the development of household electrical appliances, the early stage of powder metallurgy is mainly made of copper based oil bearing bearing. Difficult parts, such as high precision, complex shape of compressor cylinder cover, cylinder liner, as well as some special performance requirements of the product also gradually developed. Our country just all kinds of compressor of powder metallurgy structural parts demand, such as air conditioners and refrigerators for rotary compressor, the annual output of about 355 million units, and each will need to powder metallurgy structural parts 80-350g.

Connecting rod type compressor for refrigerator and its annual output is about 827 million units, and each requires powder metallurgy structural parts 100g; sliding screw type compressor of air-conditioner and refrigerator, its annual output is about 310 million units, and each is need to powder metallurgy structural parts 30~200g. Household electric appliance is a big market of powder metallurgy structural parts, but these parts are not only complex in shape, but also require high temperature and high pressure. This is also very useful for powder metallurgy factory to further improve the level of technology and equipment and technical design.

In order to reduce the noise, has entered the household washing machine and an electric fan motor is used in powder metallurgy bearing, especially low noise, can substitute for copper in iron base oil bearing, the noise of the whole machine for ~ 40dB powder metallurgy oil bearing. Because of its self lubrication, low noise, cheap price, suitable for mass production, so it is widely used in the powder metallurgy oil bearings, such as cameras, tape recorders, etc..
