Application and design of powder metallurgy iron base structure parts

20th century 30 years of powder metallurgy iron-based structure parts first in the automobile industry has been some applications, until now, in North American production of powder metallurgy structural parts of 70% above is still used in the automobile industry, in Japan even higher to reach the 90%. Their applications have been rapidly expanded to the agricultural machinery and gardening equipment, household appliances, power tools, office equipment and other uses. Powder metallurgy structural parts have been replaced in cast iron, forged steel primary or bar machining and sheet metal stamping job.

The main advantages of the powder metallurgy parts are that, under the conditions of higher productivity and lower labor cost, the parts with more dimensional tolerances can be produced. Usually, and rival of the metal forming process is compared, the cutting amount is small or no need of cutting processing, do not need to cutting expensive metal cutting machine tool, cutting tool, equipment account for the venue and technical workers.

Powder metallurgy structural parts in the early stages are used to replace parts produced by other methods. Even today, for many applications, it is still the case. However, in order to make full use of the advantages of powder metallurgy process, such as energy saving, material saving, and now more and more parts from the beginning of the design is the use of powder metallurgy process. This technological progress, and product designers and parts manufacturers of the mutual exchange, coordination and cooperation is increasingly related to.

Products not only to the use of conditions, performance requirements to design, but also to take into account the advantages and disadvantages of the expected manufacturing process. In the early stage of product design, the powder metallurgy process should be considered as a possible production process. When considering the design of powder metallurgy structural parts, it is necessary to consider how to press forming. This involves the use of a single axial rigid mold to suppress the principle of metal powder.
