The History of Clinching / Hemming

• Starts with High Speed Lines using Hydraulic Clinch Presses with Tool Change

– Disadvantages » Requires Batch Build

• Moves to Captive Lines with Table Top Hemmers (Electric or Hydraulic Drive)

– Disadvantages » Model Specific

» High Investment for Multiple Models
