Press Hemming System
Benefits of Press Hemming
Press Hemming System is the oldest automatic hemming method that we have. Inner and outer panels are hemmed together by the hydraulic press force created from stamping presses.
Short cycle time
Hemming process in two steps: Pre-Hemming and Final-Hemming
High volume production
Suitable for large panel hemming
Produce different parts in the same operation
Table Top Hemming System
Benefits of Table Top Hemming
Optimum Panel Quality : Hemming principle of closed ring
Medium to High Volume Production
Short Cycle Time
Hemming process in two steps: Pre-Hemming and Final-Hemming
Highly Adaptable Process
Suitable for high-mix, low-production, and most complex geometries
Small floor space used
Table top hemming uses a table-top mold specially designed for the product to hem the panels. It uses series of electrically actuated heads.

Robotic Roller Hemming System
Features of Roller Hemming
Flexibility
No limitation on the flange angles, rollers can adjust up to 130˚
No limitation on part shape, changeable roller hemming heads and system to accommodate to different parts.
Re-programmability; quick program changes
Suitable for any size of production through implementation of multiple robots and rollers.
Simplified and compact design lowers investment cost and floor space used
Environmentally Friendly
Absence of hydraulic driving source
Less Noise
Constant hemming pressure maintained using pneumatic pressure
Hemming pressure monitored and recorded using embedded sensor and PC connection
Robotic roller hemming system folds the edge of the panels on doors, hoods of automobiles and appliances using roller tools to roll the panels on increments instead of using the traditional press or hydraulic link tools. Panels are clamped in a tool bed in an automated cell while robots with rollers attached.

Servo Motor Hemming System
Patented servo motor hemming system enables production lines to implement roller hemming system even for a high quantity mass production. This system ensures that the process time is efficient, and that there is no quality dispersion from the differences in robots’ operation skills. These servo hemming system are widely used by global vehicle makers.
Hemming quality maintained by controlling pressure force and pressing time
System can be designed to pre-punch and main punch in 1 step to shorten cycle time, or separate into 2 steps depending on the panel characteristics
System uses minimal floor space for efficient line configuration
Eliminating hydraulic use improves noise control, work environment and lowers running cost
Configuration mechanism is simplified, and the top section of the machine is open for easier and safe maintenance and repair
Hemming units are standardized – future recycling and replacements are available
Hybrid hemming system combines mechanical (table top or press) hemming and roller hemming to accommodate use of roller hemming system for precision while fulfilling a large volume production.

Optimizing hemming’s quality
Hemming quality can be controlled by sequential operation of each units, and controlling the pressing speed, pressing power and position, and pressing time. In servo hemming system, we can set up the acceleration, deceleration, speed, position, time and torque by using HMI in the expert mode.
