Engineered Hemming Solutions

Joining inner and outer sheet metal panels is a critical process that significantly affects closure function and vehicle appearance. With decades of experience in the art + science of hemming, our team works directly with vehicle OEM’s to make sure the final closure design can be manufactured without compromise.

Hem Process Development

Our dedicated team of sheet metal hemming experts gets involved in the early stages of product development in order to ensure optimum results. Complete flange and snap studies are conducted in 3D so potential challenges are overcome in the virtual space prior to die development.

Robotic Roller Hemming

Roller hemming combines standard industrial robots equipped with a standard roller hemming head that follows the contour of the outer flanges of a sheet metal component, optimally hemming it over an inner panel which is precisely nested in a die. Our flexible process offers numerous advantages over traditional techniques including reduced capital investment costs with superior dimensional quality.

Roller Hemming Heads

Standard roller heads for all typical applications:

Basic heads (single roller, no load monitoring)
Flexible heads (multiple rollers with load monitoring)
Custom head design for unique applications

Press Hemming

Our press hemming solutions offer great speed and deliver high quality results every time.

Hem Die Sets

Hem Die Sets are an economical hemming alternative and are compatible with hydraulic and electric presses. The use of standard sub-assembled components reduces the overall manufacturing cost.
