Products lke Mobile Devices Micro Screws are primarily used in the industrial sector, and most of us have never seen or heard of them.

You might say they're not very common in everyday life, but they play an irreplaceable role in the industrial sector.

When punching and blanking sheet metal for Mobile Devices Micro Screws, rounded edges and burrs will appear. This is especially true during the initial stages of mass production, when the molds wear out, as burrs become more severe and can even cause cuts.

So, when creating molds based on drawings, it's important to clearly indicate the direction of the burrs according to the intended function. When punching holes in sheet metal casting, 1/3 to 2/5 of the cut surface near the male die is flat, while 3/5 to 2/3 of the cut surface near the female die is beveled.

Therefore, when making or checking the dimensions of the die, the hole diameter should be based on the punch tip, while the outer dimensions of the material should be based on the inner dimensions of the die when cutting.

After the sheet metal is lowered, the material is squeezed to the sides of the edge, resulting in a width larger than the original size. The protrusion size is related to the thickness of the material used, with the thicker the better.

To avoid this phenomenon, you can pre-create a semicircle on both sides of the curve. The diameter of the semicircle should be greater than 1.5 times the material thickness. When designing the A-surface, the material reflection should be handled in the same way.
