Sintermetal makes 6000 a month of these ferrous gears for the closing mechanisms in automatic household doors.

~.

SINTERMETAL of Barcelona, Spain, is making 6000 ferrous gears a month. They are for the return mechanism in automatic household doors. The sintered gear, weighing 22 g, is 14 m m high and 20 m m in diameter. A mechanical press operating at 500 M P a compacts powder consisting of iron, carbon, nickel, copper and molybdenum.

Sintering makes low cost missile part A SUPPORT base for a missile's guidance system, made by Pacific Sintered Metals of Los Angeles, California, USA, has been designed for manufacture by powder metallurgy (PM). Machining, an alternative way of making the component, would cost twice as much. The final 3.2 mm thick 316L stainless steel base weighs 5.31 g and measures 26.4 mm x 26.7 mm after it has been milled, plated with zinc and after holes have

been tapped. The 45 t o n n e mechanical press that compacts the powder gives a green part with a density of 6.5 g/cm a. Afar sintering at 1200°C in hydrogen, the density is 6.6 g/cm a. The hardness of the base is 68 Rb. The ultimate tensile and fatigue strengths are 422 kPa and 940 kPa, respectively.
