Metal encapsulated component sealing unit - has rotary table with chambers carrying components beneath pressing plate

摘要

Reduced content of residual oxygen is hermetically sealed metal encapsulation is achieved by filling the part with a protective gas and then closing its housing to ensure the seal. The simple machine for the sealing and short operating cycle lowers the mfg. costs while the evacuation and gas filling are carried out without mechanical switching elements. The rotary table (11) features a number of chambers (13) to carry the treated part (14) and part of the chambers trajectory is covered up by the sealing plate. The plate has gas channels (20-25) as well as a bore (26) for the closing tool, and it moves in a stationary housing (17) when pressing the surface of the table. The pressure is exerted by the gas fed to the housing (17).
