Features The grippers are designed to be inherently safe while applying high holding force to the tube during the balloon forming process. The left gripper clamp closes the distal end of the tube after an optical sensor has been triggered by the operator. The right and left actuators are able to stretch the parison with up to 120lbf during a forming process. During stretching, the right gripper utilizes high-friction materials and increased surface area to hold the tube without collapsing it. Up to 750psi of pressure can be applied during the balloon forming process. The tube grabber uses a tuohy borst style clamp to hold the tube while delivering the high-pressure nitrogen to the balloon. Designed with simplicity in mind, our system allows a full portfolio of products to be manufactured with only a few, easily interchangeable modules. The module is the interchangeable assembly that the mold is inserted into. It contains all the control electronics for heating the mold, as well as the water passages for cooling. Modules come in 3 different sizes -small, medium, and large – (which correlate to the mold OD). Small and medium modules can be from 1 – 4 stacks long, while a large module can be a single or double stack.
