AIR RING
Definiti Air Volume Controlled Automatic Air Ring
Definiti Air Volume Controlled Automatic Air Ring adopts stepper motor and air valve combination to control the air volume in the air chamber, combined with efficient near infrared laser thickness measurement system, so as to control the thickness of the film.
Advantages of Automatic air ring
Feeding technology must be carefully designed to avoid false sensing caused by capacitive sensors and uneven mixing caused by dead zones in the raw material mixing. Difini's feeders are market leaders in durability, and some of our systems have been known to operate continuously for over 25 years!
Independently developed weighing algorithm
-- Deep customized development capabilities
Our self-developed algorithm supports the integration of various weighing devices, whether it is static weighing or dynamic weighing, it can provide accurate weight loss calculation. At the same time, the software has powerful data processing and real-time monitoring functions, which can identify abnormalities in time and ensure smooth production. In addition, the system can be customized according to customer needs, providing flexible interfaces and expansion functions to adapt to different business scenarios.
