W. Amsler Equipment Inc., Richmond Hill, Ont., has extended its line of leak testers with an innovative flying-head design that offers blow molders high output, flexibility, and tool-free changeovers. The new five-head unit, which runs up to 250 bottles/min, is for containers up to 2L for beverage, personal-care, consumer goods, and other markets. The leak tester uses low-pressure air to detect holes as small as 0.006-in. diam. It also detects fallen bottles and choked or blocked necks. Extra heads can be added to increase speed and productivity.
The five heads travel with the bottles along the conveyor in an enclosed system. Servo motors are used instead of an indexing conveyor or stationary heads to control the traveling heads, which enables the heads to move more quickly. The compact linear system reportedly is smaller and more flexible than competitive linear and rotary machines.
