Powder Metallurgy Products

Product families below are built from the company's stated focus — precision micro gears, oil-impregnated bearings and high-strength structural parts — together with legacy application concepts. Specific grades, tolerances and certified capabilities are confirmed per project.

Automotive & Transportation · Power Tools

Sintered Gears

Sintered gears are powder metallurgy components pressed and sintered to near-net shape. The process suits high-volume production of repeatable gear geometries in iron-, copper- and stainless-steel-based powders, for automotive, power tool, office equipment and smart home drive trains.

Sintered Bushings

Sintered bushings and oil-impregnated bearings are pressed from metal powder and sintered with a controlled porous structure that can hold lubricating oil. They provide a self-lubricating, cost-efficient bearing solution for high-volume rotating and sliding applications.
