ABSTRACT:
A cast-formed bi-metallic worm in a mechanical screw press for expressing liquids from fibrous materials and a method of manufacture thereof. The worm is rotatably driven by the presses drive shaft and includes a body adapted to slidably engage around and be driven by the drive shaft and a flight extending radially outward from within the body. The body is formed of a ductal homogeneous cast material while the flight, which may be continuous or split, is cast formed of a harder homogeneous material so as to mechanically engage within and be rotatably driven by the body. The worm may also include a wear resistant cast-formed shell around the periphery of the body formed of either the same material as the flight or another hard wear resistant material.
