Applications
Detailed Information
Half star punch blades are used to create ventilation patterns on film in vacuum packaging. D2 tool steel offers both wear resistance and dimensional stability thanks to its high chromium content.
Heat Treatment: Special heat treatment process achieves HRC 58-60 hardness with adequate toughness balance.
Geometry: The half star pattern creates optimal ventilation area in the film while maintaining package integrity.
Coating: TiN (Titanium Nitride) PVD coating significantly increases surface hardness, reduces friction by 40%, and extends blade life 3-5x.
