... a reciprocating screw. Upon heating, the metal chips are converted by the shear action of the screw into a thixotropic, low-solid-content slurry (solid fraction less than 0.3), which is fed into the shot accumulator by the rotating screw. Once the accumulation chamber is filled, the slurry is injected in the mold...
