This machine is a fully automatic tube expanding machine ideal for the mass production of heat exchangers used in air-conditioning units. The equipment expands holes in the exchanger and performs the 2nd and 3rd flaring and rolling rims. When expanding, the expansion rod and expansion bullet go into the copper tube in order to make the tube wide enough to cling to the fins.

The work pieces can be automatically transferred to the expanding station, minimizing the need for manpower and improving work efficiency.
