Schuler has now equipped its CupFormer for the production of cups for DWI cans with ServoDirect Technology.

All around the world, Schuler has commissioned several hundred presses with servo drive in the last years. In comparison to conventional presses with flywheel, they offer increased productivity, flexibility and energy efficiency. This is also why Schuler has now equipped its CupFormer for the economic production of cups for DWI cans with ServoDirect Technology.

With Schuler’s Servo CupFormer 1200, the crankshafts are directly driven by four servo motors. By varying the speed of the servo drives, the motion curve and the phase shift between the two slides can be determined accordingly. Thus, on its way to the top dead center, the crankshafts can slow down and even change direction. The so-called oscillation stroke mode results in freely programmable stroke heights of both slides.

This helps to get the maximum output per time for each cup while being able to address its individual forming process requirements – cups for standard beverage cans, or even reverse-drawn cups for aerosol or bottle cans. In this way, more different jobs can be taken on and machine use can be maximized. Each job can be run at the highest speed possible, getting more products from the invested equipment and driving up profitability.

However, with the Servo technology the machine driven by servos is also able to produce at very slow speed avoiding big buffers between cupper and bodymaker. At the same time, the amount of mechanical and electrical loss is reduced due to the elimination of flywheel, clutch, brake and drivebelt. This makes overall energy consumption more favorable and reduces the amount of maintenance and servicing required.

The machine is designed for a maximum coil width of 1.000mm and is available as complete cupping system including coil line and diesets or even as complete front-end-solution in combination with Schuler’s BodyFormer.
