[0002] The nozzle of the dispensing machine, also known as the nozzle of the dispensing machine, is the core component of the dispensing machine. Due to its different application scenarios, its shapes and types are diverse. In order to achieve precise dispensing operations, the nozzle needs to work closely with other components such as pressure control systems and motion control systems. When selecting and using the nozzle, key factors such as dispensing speed, dispensing volume, and dispensing accuracy need to be considered.
