What are the requirements for selecting an Precision Electronics Micro Screws?

2026,04,07

When sheet metal fabricators manufacture Precision Electronics Micro Screws, mold selection often largely addresses the processing challenges of sheet metal parts.

Therefore, choosing an Precision Electronics Micro Screws can be a bit stressful. Today, we've compiled some requirements for selecting an Precision Electronics Micro Screws.

1. When selecting a mold, try to choose one that can be processed in one go to ensure quality. (For example, a 28×28mm cutout can be processed multiple times with a smaller square mold, or with a rectangular mold, but this requires tool changes.

A 30×30mm square mold can be used in one go, reducing tool changes and step lines, thereby improving efficiency and quality.)

2. For features that cannot be processed in one go, choose a mold of appropriate size. If the flanging hole cannot be processed in one go, pre-punching the bottom hole and punching the flanging hole can be performed in two steps, with the mold size appropriately selected. Appropriate mold size should be determined through design calculations and empirically determined through trial punching and commissioning.

3. When selecting upper and lower molds for the same process, ensure a suitable clearance between them. Using the correct lower mold clearance offers the following advantages:

① Extended mold life.

② Improved punching performance.

③ Smaller burrs.

④ Cleaner, neater holes.

⑤ Reduced likelihood of sticking.

⑥ Workpiece leveling.

⑦ More accurate hole placement.

⑧ Minimal punching force required.
