How to prevent materials from tearing or deforming during press processing?

In the stamping process of precision presses, preventing material tearing or deformation is a key purpose of process optimization, which is directly related to the excellence of formed parts and process stability.

In order to avoid material tearing, during the processing process, the molding temperature can be controlled to keep the material within a suitable deformation temperature range, slow down the cooling rate, reduce internal stress, and help avoid tearing.

The design of the mold plays an important role in the molding process of the material. Proper mold design reduces the risk of tearing by reducing stress awareness and avoiding localized overstretching.

Appropriately reducing the forming speed of the press will help slow down the deformation speed of the material, reduce strain accumulation, and reduce the chance of tearing.

Reasonable selection of lubricants ensures sufficient lubrication of the material layer during the entire molding process, reduces friction resistance, and reduces the chance of tearing.

In order to avoid material deformation, when selecting the thickness of the material, avoid being too thin or too thick to reduce the problem of material deformation and enhance the controllability of molding.

During processing, using appropriate cooling technology, coupled with water cooling, can help control cloth temperature and avoid excessive deformation. By adjusting the forming process parameters such as stress, temperature, and speed, it can adapt to the characteristics of the material and reduce the possibility of deformation. For large or specially shaped parts, the incidence of deformation can be reduced by using appropriate auxiliary systems.
