Machine drawing of vertical expander
The vertical expander is specialized tube joint expansion equipment for the production of finned heat exchangers. It finishes the technological processes of tube expansion, orifice expansion and flanging all in one complete working cycle. The production efficiency of the vertical expander is outstanding.

Features:
1. Energy efficiency, waste minimization.
2. High-precision thanks to the expansion device’s excellent automatic functionality.
3. Two ends of the work piece are held in a fixed position, then the tube is expanded. The length of the work piece does not change, without shrinkage, reducing wasted material by 3-5%
