Burckhardt pinning and perforating tools are high precision parts, produced in various versions:
Hole-Ø < 0.05 mm – ca. 3 mm (depending on requirement, material and density of pins)
Pin density up to 300 pins/cm2 when working with segments (no space between the rings), single rings with higher density possible
High concentricity
Pin projection from 0.3 mm – ca. 12 mm
Almost any pin and hole arrangement is possible, linear, spiral – patterns according to your demand
Unaffected by temperature, also over 300° C, very good resistance to wear and tear
Special corrosion resistant steel for the complete perforating unit (suitable for food)
Big variety of supporting materials (bronze, brass, steel, stainless steel, plastic, aluminium, wood, etc.)
Ultra-high-density pin perforation at 303 pins/cm2
NEW WORLD RECORD!
For special ultra-high-density perforations we have developed new perforating tools with 303 pins per square centimetre – this is a new world record!
