The DX-1805 pneumatic crimping machine is equipped with a single crimping head that is hydro pneumatic driven to crimp almost any thickness of aluminum with ease. These machines are equipped with two stable, wide body arms to hold large or small frames for ease of operation. The crimping operation is done with a single foot pedal press which causes the machine to grip the frame with a single pneumatic clamp and causes the machines to pull the frame together and crimp it at an exact 45° angle for a permanent lock. DX 1805's are built on a rigid heavy gauge steel frame for better stability.
