Screw fastening driver system

Electric Screwdriver

High-precision torque and angle control ensures consistent and stable fastening quality without variations.
Covering a torque range of 0.01 to 500 Nm, it can be used in a wide range of production environments, from manual operation to integration into automated machines and robots.
Furthermore, the "Deplug Feed Module (DFM)," which incorporates a stroke mechanism, is a compact and highly functional automation unit suitable for integration into production lines.

Controllers

In addition to torque and angle methods, it also supports screw friction management during the fastening process and automatic recognition of the seating point.
Even complex screw tightening sequences can be easily configured using drag-and-drop operations.
By recording and managing fastening data and graphs, we ensure traceability and support quality assurance and process improvement.

feeder

Based on our many years of technology and experience, we can supply a wide variety of parts, including not only screws and nuts, but also rivets, pins, washers, O-rings, and more.
By selecting the optimal supply method, such as hose pressure feeding or pick-and-place, we achieve stable supply in conjunction with the fastening process. This reduces the risk of line stoppages and contributes to improved production efficiency.

Adaptive DFS

A dissimilar material joining system using FDS or flow-formed screws.
Because it requires no pilot holes and can be installed with access from one side, it simplifies the process and reduces labor costs.
We can join different materials such as aluminum, steel plates, and castings, and have a proven track record in lightweighting fields, including automobile bodies and battery assembly.
