how tinplate elongation influences the drawing process

The elongation of tinplate is an important factor in the drawing process. Elongation refers to the ability of the material to stretch without breaking. In the case of drawing, a tinplate with a higher elongation will allow for greater deformation before fracture occurs.

When force is applied to the plunger during the drawing process, the tinplate undergoes stress and deformation. If the tinplate has a low elongation, it is more prone to fracture during the forming process. On the other hand, a tinplate with a high elongation can withstand greater deformation without breaking, resulting in a more successful drawing process.

It is important to note that the elongation of tinplate can be affected by several factors, such as the composition of the material, the thickness of the sheet and the heat treatment it has undergone. Therefore, it is necessary to carefully select tinplate with adequate elongation to ensure a successful drawing process.
