About this machine.
Eckold AG is a Swiss-based specialist in sheet-metal forming technology with a long tradition of innovation and quality. Since its founding in 1957, the company has built a reputation for designing and manufacturing precise, ingeniously simple and extremely durable machines used in sheet metal shaping and finishing tasks. Eckold's machines are engineered for chipless cold forming including shrinking, stretching and finishing and are backed by decades of expertise in forming sheet metal and profiles. The Eckold Machines range includes versatile equipment such as Kraftformer universal formers, specialised wheeling and planishing tools, all designed to deliver consistent performance across a broad range of materials and applications.
The Eckold Kraftformer range represents a family of universal sheet-metal forming machines engineered for precision, durability and versatility in chipless cold forming of sheet metal, tubes and profiles. Built on decades of experience, Kraftformers combine robust mechanical design with highly adjustable forming force and extensive tooling options, making them ideal for a wide array of forming tasks from shrinking and stretching to doming, planishing, straightening, notching and more.
Available in multiple configurations to suit different workshop and industrial needs, the range includes compact models for general forming and rework, medium-sized machines with continuously adjustable stroke speed and the Piccolo featuring precision hand-wheel control, and larger, high-capacity units with a wide working reach and the Magnum with servo-driven controls and stored machining programs for repeatable results. What sets the Kraftformer series apart is its quick-change tooling system and finely tunable forming force, which together enable rapid adaptation to varied tasks and material thicknesses while delivering consistent, high-quality results.
