Thermal Bonding

Robust and stable thermal bonding machine designed to provide the user with an effective and reliable production machine for bonding all sorts of balloon and catheter components with minimal cost of ownership. The BT-NG machines is a thermal bonding machine based on the hot-jaw principle. It incorporates 25 years of experience with the thermal bonding process. The small stainless steel dies used in the machines have accurate temperature control and heat up very fast. The BT-NG has a mximum of four cavities that can be utilized at two different temperatures. The cavity position is software controlled. The dies and closing gripper are mounted in an exchangeable unit. This allows for very fast switching between dies by replacing this unit with another unit with a different set of dies. Alignment is accurate and therefore the


The CT Reflow Chamber has process repeatability, high yield, and uniformity to further reinforce the use of tubing centering guides to ensure accurate catheter centering within the heat zone. Traverse speed and length settings are entered via touch-screen HMI and a motion controller ensures precision and repeatability. This system is capable of multiple lengths and speed transitions within a single cycle and within the heat zone, and independent temperature control of each thermal nozzle. The Cath-Tech Reflow prevents the longitudinal elongation and uneven recovery problems associated with oven use.
