Configuration approach

Start with a proven architecture. Engineer what matters.

Single-head station

Dual-head high-end system

Multi-size screw line

Robot-integrated fastening

Final performance, safety concept, footprint and validation plan are defined against the customer URS, product samples and acceptance criteria.

Precision driver option

PRO-FUSE Precision Driver

For ultra-fine fastening applications, Ito can integrate PRO-FUSE electric drivers into a complete automation cell with customized bits, vacuum mouthpieces, screw feeding, robot motion, inspection and fastening-result traceability.
