Machinery for the Wire & Fastener Industries

VEM

  

The VEM 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 VEM machines can be either hand fed or equipped with a magazine.

  • 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.

  • When extruding scaled bars, the extrusion die breaks the scale and extrudes the bars to the pitch diameter, leaving a clean face that results in very good thread quality.

  • Extrusion stroke adjustment is external and takes seconds.

  • The VEM machines are available with higher tonnage ratings for upsetting and heading.  The machines can be supplied with 1 or 2 stations with either open dies and closed dies and heading tonnage up to 400 tons.

  • Fully automatic machines from coil are available up to Ø25mm.

  • The machines are equipped with oil or spray mist that applies extrusion oil around the bars before extruding.
