ABSTRACT:
A method and apparatus for recovering and reusing solder following the removal from radiators or the like requiring repair. The solder is melted or otherwise removed from the radiator core, heated, formed into billets, trimmed to remove foreign particles and then placed into a short stroke extruding machine forming the solder into a continuous strand which is coiled and reused. To achieve the maximum stroke with the minimum space the extruding mechanism includes a pivotably mounted ram within a framework adjacent the die chamber and includes as an integral portion thereof a particularly designed trunnion having an elongated hole to receive the bearing and a flat portion whereby the full extrusion force is absorbed by the end plate of the framework without undue stress being placed upon the bearing itself.
