Y28 double-acting sheet stretching
 

 

 This machine is mainly used for the sheet stretching, bending and forming which can also used for pressing the plastices, cold-extruded bending, revising the mold, pressing and so on. The drawing cylinder of this series can be used as cushioning device, blanking and punching. Under the set force of the system, the working force of each socket can be adjusted separately. In order to make sure the quality of stretching and blank pressuring, we add the blank pressuring cylinder pressure maintaining system.The working force, pressing speed and travel of this series can be adjusted within its limits based on the requires.
