Showa Precision Tools have manufactured punching and forming dies for magnetic disks (magnetic vapor deposited film), liners (non-woven fabric), shutters (SUS), and hubs (SUS).
For these dies, if the clearance is too wide the workpiece material fibers can get into the gap between the punch and the die, especially for liners which have fibers with a diameter of only a few microns. If it happened, the product and the scraps would then be connected, causing feed defects. Our clients used to use "caulking" in order to further reduce the clearance.
Caulking is a technique which consists in tapping the upper surface of the die near the punch entrance area in order to fill any gap.
This is often used during production as the clearance widens with usage of the die, which can be an issue. In some cases, manufacturers would only be able to run their press for 30mn, after what they would need to stop production for 1h in order to apply this caulking technique...
However we have been able to solve this problem thanks to our high precision parts machining and assembly technology, by conceiving and manufacturing a die which succeeded in maintaining a uniform clearance of 1 micron with dynamic precision.
This technology is also used in our battery electrode foil punching dies technology.
