Dual Catheter Laminator


This machine uses recirculated hot air to shrink plastic tubing down to a minimal diameter for the production of catheters. Two catheters can be processed at once using one heating chamber.


The flexible programming capabilities enable the machine to laminate anything that can be held by the mount collets but catheters are the primary products.

Design Highlights:

The precise control of all variables is increasingly important, as the process specifications get tighter. Programmable temperature and variable speeds enable heat-shrinking tubing close to the melt temperature. The unique use of a patented hot air recirculation process allows hot air to be contained within the system, instead of being expelled to the surroundings. This also helps maintain a precise steady state temperature. Temperature offsets allow calibration by external probes. The long heating area maximizes the time at temperature for faster processing which allows this machine to shrink tubing faster than any other. Pneumatic setups are not necessary with this model’s innovative design.


This vertical machine is smaller than the standard lamination machine and the two shrink areas operate in parallel so the production for a given floor space is maximized. This machine takes less space than a horizontal laminator and eliminates the complex tension controls as tensioning is accomplished with fixed weights. By improving the accuracy of all controlled parameters, this machine can increase productivity through reduced rejects and faster processing speeds. The programming is flexible to allow new products to be made with the same machine. With the availability of better technology, product designers are finding they can build better devices.
