SYNCRO Air Ring by LIPM s.r.o. – Next-generation cooling ring for film production

An air ring for plastic film production as the foundation of a stable and efficient process

An air ring, or cooling ring, is an essential component of every blown film line. Its main function is to provide uniform and controlled cooling of the film bubble immediately after it exits the extrusion die. The quality of this cooling has a direct impact on the thickness profile, the mechanical properties of the film and the stability of the production process itself.

SYNCRO, as one of the technology leaders in blown film line automation and control, is bringing a new generation of air rings to the market. These are designed with an emphasis on high efficiency, easy integration into existing systems and minimising operating costs. A key element is optimised airflow, developed using CFD simulations. As a result, cooling is not only uniform but also energy-efficient.

Another advantage is automatic adjustment of the ring height according to current operating conditions, ensuring maximum flexibility during production. The equipment’s modular design significantly simplifies cleaning and maintenance. The SYNCRO air ring is also fully compatible with modern automatic film thickness control systems, enabling manufacturers to achieve precise output even at high speeds.

Measurable benefits of the SYNCRO air ring in practice

The experience of manufacturers who have already implemented the SYNCRO air ring in their lines demonstrates clear benefits. Film thickness variation is reduced by up to 40 %, yield increases by 10–15 % and production start-up time is shortened, which also has a positive impact on overall energy consumption. According to one LDPE film manufacturer, the investment in the system paid for itself within a single year of operation.

“Thanks to the SYNCRO air ring, we have achieved higher quality at lower operating costs. The investment paid for itself within one year,” says a representative of a Czech film manufacturing company.
