Roll Forming Process Basics

Understanding the roll forming process helps appreciate machine design and productivity parameters:

• Coiled metal sheet or strip is fed into the roll former
• The strip passes through consecutive rolling stations
• Each station progressively forms the material through a series of rolling dies
• Stations can perform processes like punching, notching, cutting
• The fully formed profile is cut off at the end
• Material is formed gradually without extremes of stress/strain

Benefits of roll forming:

• Highly productive continuous process
• Consistent quality and tolerance
• Efficient material utilization with low waste
• Flexibility to change profiles with quick roll change
• Allows complex custom shapes

A key metric is feet of material produced per minute. Robust machine design by Tishken allows maximizing production speeds.
