Company: Schober USA, www.schoberusa.com
Product: Tungsten Carbide dies
What are they?: Tungsten Carbide dies from Schober USA are used to manufacture various products such as flexible packaging, folding cartons, high-volume household and personal care products, technical parts, and more.
Features/Capabilities:
• Available in solid or segmented designs or with shells
• Maximum length of 13.8˝ and a maximum diameter of 7.8˝
• Can absorb vibrations and keep all relevant parameters to minimum variation for predictable die/anvil life cycles
• Can be re-sharpened as often as regular dies
Company: Gerhardt, www.gerhardt-usa.com
Product: Five Star & Seven Star Rotary Dies
What are they?: Gerhardt manufactures a complete line of rotary cutting tools, which are made from premium grade tool steel for all diecutting applications.
Features/Capabilities:
• High-quality tool steel
• The Five Star Rotary Die is CNC engraved and fully hardened, designed for paper and films, and custom designed to high industry standards
• The Seven Star Rotary Die is EDM Spark Eroded and is fully hardened, is designed for tight tolerances and complex geometries, and is designed to be extremely durable in metal-to-metal applications.
Company: Bunting Magnetics, www.buntingmagnetics.com
Product: Magnetic CerfaceTM Die-Cutting Cylinders
What are they?: Diecutting cylinders
Features/Capabilities:
• RP shearing action, resulting in the highest level of cut quality
• Various steel alloys, several hardening techniques, and designs with and without journals.
• Surface-mounted ceramic magnets that create a super-hard, abrasion-resistant surface over a strong, solid-metal core designed to eliminate deflection.
Company: RotoMetrics, www.rotometrics.com
Product: Multi-Score Flexible Dies
What are they?: These dies combine scoring technology with a flexible die that runs on a magnetic cylinder cutting against an anvil roll, allowing converters, whose presses have die stations without removable anvil rolls, to run folding-carton jobs.
Features/Capabilities:
• Standard plate height of 0.035˝
• Die must be run as an “undercutter” unless the converter is able to use a turn bar to flip the web
• The carton dieline should be rotated slightly, so there is no true cross blade on the die, configured at approximately a 5-degree angle on the layout
