LINK MOTION PRESSES
LINK Motion Presses were designed to increase Metal Stamping output speeds and at the same time reduce Snap Thru / Reverse Tonnage during press operations. Link Motion was originally invented by Mr. Howe in 1848, originally for the Rail Road industry. By slowing down the motion this assisted in preventing the steel rail wheel from slipping on the steel track.

Sutherland Presses has incorporated the Link Motion into our EHL Series line of stamping presses. This feature provides as much as a <40%> Slow Down when the press slide closes and the dies and material are metal to metal.

Initial machine cost is higher than conventional motion presses, however the payback is shown in higher part output, more machine time availability and greatly increased die lie between die maintenance. Especially true for the automotive industry who has great pressure to lighten the weight of each car produced, the high strength steel is very resistant to bending and forming operations. By having the dies closed for a longer period of time, allows the material more time to flow and stay in position.

Cross Bar Knuckle Joint Link Presses, not only offer the slow down mentioned above, but have a momentary dwell at the bottom dead center (BDC) point of the stroke.
