Answer: When the stainless steel sieve plate is processed, it sometimes deforms. It is actually related to raw materials. Therefore, in the manufacture of stainless steel sieve plates, the raw materials of stainless steel sieve plates must be carefully selected. Choosing a good raw material will reduce the chance of deformation of the stainless steel frit in the manufacturing process and produce more high quality stainless steel screens.
  When the stainless steel sieve plate is sheared, the sheet material is subjected to a bending moment and is easily bent. If the bending moment is too large, it is equal to the convex bending of the sheet material, although there is springback after cutting, there is still residual bending deformation. Since a considerable number of products of stainless steel punched screens have high requirements for flatness, the problem of bending is highlighted. In order to prevent bending, it is difficult to generate bending moments from the processing conditions when the shearing is changed, but it is not clear what kind of processing conditions are appropriate.
