  • Forming an extruded bar out of metal chips
    Patent number: 4174933
    Abstract: Apparatus for extruding metal chips or filings into a bar stock. The extruding machine uses graphite lubrication, and an oversized wooden (or other compressible material) plug for the initial compaction. The face of the ram contains undulations therein so the ends of adjacent charges will be better held together.

  • Briquette forming apparatus
    Patent number: 4123210
    Abstract: A briquette forming apparatus for compressing a mass of metallic chips into uniformly dense briquettes. The chips are first heated to reduce their yield strength and to simultaneously remove volatile contaminants therefrom. The hot chips are then transferred to a reciprocating press where the chips are compacted in a flared die between a convex anvil and a reciprocating ram.
