Catheter Liner Stretcher

We are proud to showcase the CATH-TECH™ Liner Stretcher from our sister company R&D Engineering. This leading-edge equipment line uses a combination of heat and tension to process a liner to a fixed mandrel. This automated process eliminates the need for the operator to hand stretch a liner. 

The CATH-TECH Liner Stretcher and its process allow the liner to sit tight against the mandrel with minimal relaxation. Because of the fine machine control combined with the process, throughput is increased, scraped units are decreased, and etching issues (“white liner”) are diminished. This process also eliminates operator safety and health issues related to Carpal Tunnel Syndrome.
