Abstract

The invention relates to a method of producing sleeves for mini-feeders. According to the invention, a fluorine-free mixture, which contains aluminiu m silicate microspheres, an oxidizable metal, such as aluminium powder, an oxidizable agent and magnesium by way of an exothermic reaction initiator, i s introduced by means of blowing into a mould comprising two male parts in ord er to produce a sleeve having two openings, one of which is sealed with a plug before use.
