Ultrasonic Zinc Alloy Injection Molded Parts Sprue Gate Separation Cutting Machine: High efficiency, short cycle time (less than 1 second), clean cross-section, easy to automate conversion. The robotic arm of the injection molding machine is used to remove the product and place it on the ultrasonic vibration head. Simultaneously, the ultrasonic system activates, and the required plastic parts automatically detach from the material tray. The robotic arm then carries away the excess sprue, making the process convenient and fast, enabling unmanned operation and significantly improving production efficiency.
