Cylindrical Cell Electrode Winding Machine Winder for 18650 26650 32650 Battery Research

Features

It is a semi-automatic winding machine for accurate assembly of single cylindrical cell cores (also known as “jelly roll”). Using this machine, cathode and anode films, separated by top and bottom separator films, are rolled up into a hollow cylinder casing for cylindrical battery applications. It is an ideal tool for the reliable and precise production of high-quality windings of electrode cores.
