CNC bending machine processing process, due to the heating speed, so that the mold can not be uniform heating effect, so it is easy to produce a larger temperature difference, and this is the main reason of stress and change. Once there is a profit in the mold, it is prone to deformation.
Thus it can be seen that only when the heating of the pipe bender is uniform can the deformation phenomenon be avoided. So the most important thing is to control the heating speed and temperature regulation, so that the mold has a good heat treatment effect, so that the possibility of deformation in use will be reduced.
