Hosokawa Alpine has set another milestone in efficient and stable blown film production with the further development of its bubble diameter control (BDC) system.

The new solution combines innovative sensor technology with a modern software architecture, ensuring faster control processes, consistently high product quality and greater system availability.

Hosokawa Alpine’s BDC film bubble diameter control system precisely detects changes in the film bubble.

New sensor arrangement for more precise control

A key component of the optimization is the new positioning of the sensors. These are now mounted directly on the moving support arms rather than on the frame of the calibration basket. This allows them to be flexibly adapted to the respective process conditions and to detect changes in the film bubble with even greater precision.

In combination with a modern software architecture and optimized control logic, the system responds significantly faster to process fluctuations. The result is greater process stability, a stable film bubble and more efficient production.

Compatible with existing production lines

Another key advantage of the new solution is that it can be easily integrated into existing blown film lines. Companies thus benefit from a cost-effective retrofit option that can be implemented as part of modifications to existing lines.

With the optimized BDC bubble diameter control system, Hosokawa Alpine enables its customers to future-proof their existing production lines whilst benefiting from greater process reliability, improved efficiency and increased system availability.
