Flexible Hose Fabrication on a Collapsible Mandrel

FEHER Machine & Manufacturing


The goal of this project was to design and test several possible designs of collapsible mandrel. When a hose is formed over a mandrel, it is difficult to remove from the mandrel because of the large contact area between the outer surface of the mandrel tube and the inner surface of the hose. This contact area causes the hose to stick to the mandrel, making hose removal difficult.


This project explored designing a collapsible system which eases the removal of a mandrel from a hose.
