Residual stresses are mechanical, residual stresses generated by internal forces in the injection-molded part during the injection molding cycle.
In this webinar, we will show how to reduce the effects of residual stress manifested as part deformation after ejection.
One option is to modify the part shape to increase its stiffness against internal forces.
Another option is to adjust injection parameters to reduce the magnitude of internal forces.
Similarly, we can reduce internal forces through mold design—by designing the gating and cooling systems.
Another way to reduce deformation is local correction of the mold cavity shape with an opposite deformation.
