Metallizing gun for applying sprayed metal

摘要

Metals with a relatively low melting point can be sprayed in the form of droplets which coalesce to form a coating. A metallizing gun is used for this purpose which comprises a thinwalled container of steel for the liquid metal which is surrounded by a massive block consisting of an alloy of a thermally conductive metal, which contains an electric heating element and a temperature sensor and whose external side serves to mount air ducts which transmit heat to the block and connect to the spray nozzle.
