What is the core rule for micro-hole perforated plates?
The Golden Rule: Plate thickness (t) must be ≤ hole diameter (d). This is the basic manufacturing limit for punching micro-holes (generally φ0.5-φ3mm).
Thicker is stiffer, but: If the plate is too thick relative to the hole size, the punch pins will break and the plate will suffer severe local stretching.
