Patent protected technology for great efficient work, one worker can operate 3-4 machines.
High precision fin aligning with linear rail and servo motor control for zero fault work.
Optimized sucker system can take fin accurately and quickly.
Specially designed fin hopper for automatic feeding and up to 5 kinds of fin shape.
More than 25 parts has been optimized and upgraded during two years practice.

The automatic fin aligning and expanding machine is the up to date machine for no frost refrigerator evaporator fin and tube assembling work. Compare to traditional fin aligning manually, the automatic machine take fin by sucker and put fin in molds in exact position by servo motor control. With hydraulic pushing device to push aluminum tube into fin alignment with expanding, the aluminum fin will laminate on tube tightly for better heat exchange efficiency.
