Sammi Precision Co., Ltd

Sammi Precision Co., Ltd., is an automotive body assembly system manufacturer for global Automotive makers and tier 1s. Their automotive body assembly line including Body In White welding and assembly system, quality checking fixture, and hemming system are developed, machined and implemented in house. With 2 ISO 9001 certified manufacturing plants and a strong R&D division, they have 24 years of developing their own hemming system that differentiates their machines from standard hemming systems, including patented servo motor hemming system, servo motor link-type hemming technology and hybrid hemming system. It holds a variety of patent on in-house developed technology and methods.

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.
