Luben Glass has developed a direct air lock ring to support higher production speeds.
The company’s R&D team carried out fluid dynamics studies on conventional blowhead arms systems, resulting in the creation of the lock ring.
The product features an enlarged air passage specifically engineered to improve forming efficiency.
The final shape of a glass container is achieved through the injection of compressed air via the blowhead arm.
Working in conjunction with the locking system, this process allows the container to fully develop its intended geometry while ensuring proper cooling before leaving the mold.
As market demands continue to push production rates higher, manufacturers face an increasingly important challenge: maintaining forming quality despite shorter mold residence times.
When production speeds increase, the time available for forming and cooling is reduced, making it essential to deliver a greater volume of air in a shorter period through the blowhead arm–lock ring assembly.
Traditional systems designed around standard production speeds often struggle to meet these new requirements.
Their air passages can become a limiting factor, restricting airflow and potentially leading to forming defects, reduced process stability, and compromised product quality.
Luben Glass says its new product addresses this challenge.
The new lock ring, combined with a blowhead arm incorporating a direct air passage, increases airflow by up to 45% compared to traditional solutions.
This enables more effective container forming, enhanced cooling performance, and greater process stability, even under demanding production conditions.
