The Japan Powder Metallurgy Association (JPMA) has reported that the production of Powder Metallurgy structural parts and sintered bearings in Japan remained stable in 2018. Figures released by the Japan Ministry of Technology and Industry (METI) showed that structural (machine) PM part production was 88,605 tons in 2018, up from 88,484 in 2017. Sintered bearing production fell slightly, with 6,704 tons produced in 2018, compared to 6,741 tons in the previous year.

The reported value of both structural PM parts and sintered bearings increased in 2018. PM structural (machine) parts were valued at Yen 112,671 billion in 2018, up from  Yen 110,904 billion in 2017, with the value of sintered bearings increasing to Yen 16,033 billion in 2018 from Yen 15,843 billion in 2017.

Powder Metallurgy: The original net-shape production process

Powder Metallurgy components are relied upon by a wide variety of manufacturing industries, from automotive to power tools, household appliances, chemical engineering, filtration and more.

The main reason for the technology’s success is its cost-effectiveness at producing high volumes of net-shape components, combined with its ability to allow the manufacture of products that, because of the production processes, simply cannot be manufactured by other methods.

To discover more about how the technology has revolutionised component production, browse our Introduction to Powder Metallurgy.
