What are the problems and solutions for Precision Electronics Micro Screws?

2025,08,18

Common defects and causes of blanking parts in Precision Electronics Micro Screws. Blanking is a stamping process that uses dies to separate metal sheets.

Common defects in blanked parts include burrs, surface warping, and dimensional deviations. While burrs of varying degrees are difficult to avoid when blanking sheet metal, they can be reduced by improving part machinability and optimizing stamping conditions. 1. Mold manufacturing errors - mold parts not matching the drawings, poor parallelism of the baseplates, etc.

2. Mold assembly errors - large play between guides, uneven assembly of male and female molds, etc.

3. Poor press precision - if the press guide rail play is too large, the slide bottom is not parallel to the worktable surface, or the slide stroke is not perpendicular to the press table surface, poor worktable rigidity can cause deflection during blanking, leading to gap variations.

4. Installation errors - if the upper and lower mold baseplates are not cleaned during installation, or if the mold fastening method on large molds is improper, and the upper and lower molds are not installed concentrically (especially molds without guide posts), the working part can tilt.

5. Improper Precision Electronics Micro Screws structure - insufficient rigidity between the mold and the working part, resulting in unbalanced blanking force.

6. Excessive steel plate bending - uneven steel plate.
