Introducing a case study of quality improvement VE for precision press molds proposed to customers!
The quality of precision press-processed products greatly varies depending on the quality of the press molds. The molds for thin sheets and fine precision press products must have a sophisticated structure to enhance product accuracy. While measures taken during mold processing are certainly important for improving the quality of press molds, the most crucial measures are those taken during the design phase. Furthermore, by conducting various analyses such as structural analysis, flow analysis, and stress analysis based on a reasonable press mold design, it becomes possible to manufacture precision press molds with higher accuracy and quality. [Examples] - Strength enhancement of separation cutting type press mold dies - Measures against resin overflow in resin sealing molds - Damage prevention for comb tooth punches used in precision fine molds - Measures against dents during the extraction process of die molds - Laminating molding methods for secondary batteries - Improvement of mold frame bite issues, etc. *For more details, please refer to the PDF materials or feel free to contact us.

basic information
**Case Study: Strength Improvement of Separation Cutting Type Press Die** ■Before In separation cutting type press dies with narrow pitch multi-row arrangements, there are cases where the thickness of the parts cannot be sufficiently secured, leading to insufficient strength of the press die. However, simply stating that there is insufficient die strength encompasses various issues, including part breakage, cracks, warping, and deformation, which result in a lack of precision assurance, increased maintenance costs, and are expected to lead to decreased productivity. ■After By conducting stress analysis, we confirm and compare the amount of deformation and incorporate the optimal conditions into the design. We increase the thickness of the press die as much as possible and block the space between parts with spacers to suppress deformation of the parts. By minimizing the deformation of the parts, we can prevent increased maintenance costs due to press die breakage or cracks, as well as a decrease in productivity. ■Point Through stress analysis, we can quantify the strength of the part shapes and increase the thickness of the areas with insufficient strength to the maximum extent, thereby enhancing strength. Additionally, structurally filling the space between the components of the press die as a whole can help suppress deformation and deflection of the die components. *For more details, please refer to the PDF document or feel free to contact us.*
