​screw header punch manufacturers tell you that high-quality mold thimbles have the characteristics of high hardness, good toughness, wear resistance, etc., but no matter how high-quality thimbles may be deformed during use, why is this? How to reduce the occurrence of this phenomenon?

1. For symmetrical molds, the deformation of the mold thimble can be considered according to the mold cavity size, overall size and height. ​screw header punch manufacturers tell you that when the wall of the mold is thin and the height is small, it is easier to harden. At this time, it is possible that the tissue stress plays a leading role, so the cavity often tends to expand. On the contrary, if the wall thickness and height are large, it is not easy to be hardened. The ​screw header punch manufacturer tells you that thermal stress may play a leading role at this time, so it will lead to deformation of the mold ejector.
2. ​screw header punch manufacturers tell you that the problem of asymmetric mold thimble deformation is also the result of the combined effect of thermal stress and tissue stress. For example, for thin-walled and thin-sided molds, due to the thin mold wall, the temperature difference between the inside and outside during quenching is small, so the thermal stress is small; but it is easy to harden and the structural stress is large, so the deformation tends to expand the cavity.
3. ​screw header punch manufacturers tell you that when the shape of the mold cannot be changed, in order to reduce the deformation of the mold thimble, some other measures can be taken. The general consideration of these measures is to improve the cooling conditions so that each part can be cooled uniformly; in addition, various compulsory measures can also be assisted to limit the quenching deformation of the ejector pin.
If you know the reason, it is easy to find a solution. The ​screw header punch manufacturer tells you to give a solution according to your own use situation, so that the problem can be fundamentally solved!
