Matters needing attention in the drawing process of the shell of aluminum profile

- May 09, 2018-

1, tension must be cooled to below 50 degrees in the aluminum alloy section before moving to the drawing frame for stretching operation.


2, the manipulation of the amount of stretch is at 1%.


3, in order to control the amount of tensile deformation and control the size changes of the entire section, we should choose suitable special pads and suitable methods.


4, because of the effect of heat resistance, the aluminum shape material with high demand for decorative appearance must be turned up and down before and after heating, so as to achieve uniform heat dissipation.


5. During the process of picking, moving and stretching, they should not rub, pull, stack, jam or twine together, but they should reserve a certain interval between them.
