MAIN FEATURES

Model BT-S is equipped with 2-station servo table and side-blow system. After injection the servo table rotates 180 o, a servo screw then transfers a neck plate with preforms to the side-blow station. Using side-blow system a bigger work space is available, and optional devices: gate trimmer and product conveyor etc can easily be mounted inside the machine. This model is good for small containers with short cycle time.

Model BT-J, has the same benefits, but is for wide-mouth jar applications, and it’s a stronger machine with higher injection clamping force.
