The Extrusion machines extrude Cold-Drawn and Hot-Rolled (scaled) bars from major diameter to pitch diameter, allowing thread rolling of the bar ends without having to peel or turn the ends or remove the scale, the extrusion die breaks the scale and extrudes the bars to the pitch diameter, leaving a clean face that results in excellent thread quality.
The Extrusion machines can be either hand-fed or equipped with a magazine or operate automatically as part of a line of machines.
Hand-fed machines can feed headed parts and long parts as well.
The optional magazine can feed and eject short parts and medium-length parts.
