, CATH-TECH Liner Stretchers

Liner Stretcher


The CATH-TECH™  Liner Stretcher 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.


Our 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.
