摘要

A method for the production of gas having large cavities, mouldings based on (slightly -) metals with the use of at least one by compaction of a mixture of particles of at least one (slightly -) metal or a (slightly -) metal alloy with particles of at least one – at elevated temperatures a pores releasing – blowing agent added to the gas produced precursor material - shaped body, the:in at least one heatable heating - and foaming characteristics if conventionally foamed with - pass - recipient with at least one a - and at least one discharge opening is introduced,mainly in the under seal with respect to the charging opening on a above the decomposition temperature of the blowing agent and at least the melting temperature of the metal, on the hot air or alloy component of the precursor material (solidus temperature), temperature, which is heated, andwhich results due to decomposition of the blowing agent in the recipients forming and at least up to the dispensing opening in the direction of flowable - plastic state, hot metal foam in the form of a continuously discharged mainly flowable - flexible metal foam - strand in at least one cavity and is made to solidify,by means of a narrowing of the interior of the recipient in the..
