New cutting and creasing rules launched

Sandvik Coromant UK : 04 April, 2007  (New Product)
Continuous product improvement by Sandvik
Representing a first for cutting rules in the diemaking industry, Sandvik has launched a range of special hard edge coated rules. Designated Sandvik Dieflex Platinum and a slightly harder body version, Sandvik DieHard Platinum, the new rules outperform the existing hardest edge rules currently available with a hardness of 4000-5000HV. This is almost double the hardness of competitive titanium nitride edged rules and yet bendability for diemaking is not affected.

As a result of this unique coating, the cutting life of the product is greatly increased. Another key feature is a smooth surface on the bevel resulting in reduced friction during the cutting process. As the coating is very thin, there is no rounding of the edges. Sandvik Dieflex Platinum cuts tougher materials at a lower cutting pressure with improved release properties. This reduces dusting problems and at the same time gives excellent and even cutting results on long runs eg cigarette boxes and pharmaceutical packaging. Difficult and abrasive materials, such as plastic laminated board, recycled board, metallized polyester or substrates for the electronics industry can be cut equally well.

Also new is Sandvik Dieflex MicroCut, which has all of the benefits of Sandvik Dieflex rules but has a thinner edge bevel and a double bevel profile, which is different from standard cutting rules. This reduces cutting pressure and increases rule life. The thin edge bevel produces a product edge that is less likely to flake, create dust or Ďangel hairí, and cuts straighter and smoother than conventionally cut substrates. Sandvik Dieflex MicroCut is ideal for use with Sandvik Dieflex MikroNik pre-microscopically nicked rules, as it equalises cutting pressure and promotes even wear across the die. The thinner bevel also allows for easier extraction after cutting, thereby reducing dusting. Used together with Sandvik Dieflex MikroNik, cutting speeds can be increased by as much as 30%.

New to the creasing rules range is Sandvik PlastiCrease, a specially designed, microperforating, creasing rule for controlled and accurate creasing of PET, PVC and similar plastics. Developed in conjunction with Zimmer Industries, with whom Sandvik launched the Sandvik Zimmer range of perforating rules for business forms, Sandvik PlastiCrease has serrations in the rule edge, 100 teeth per inch, and with close depth and height tolerances gives a consistent, high quality and smooth crease. The new rule has been produced in response to market demands and the trend to recyclable plastics packaging for display products such as cosmetics.

All of the new rules are available in standard rule heights and sizes.

Supporting the new product launches, Sandvik has developed a novel Ďpop-upí rule selector to demonstrate how the new products fit into the overall cutting and creasing rules product range. Sample packs of the new rules have also been prepared together with technical datasheets.
