Tube Expansion Machine

Shineeast tube expansion machine adopts Shineeast air driven liquid pump to pressurize the radiating tube, making the diameter of radiating tube become larger(generally 0.3-0.4mm larger than originally), which lead to the interference fit between the radiating tube and cooling fin, so that make them close integration, instead of the traditional welding technology.
