PDC’s patented blade assemblies are custom-engineered for precision cutting and perforating operations in tamper-evident banders and shrink sleeve labelers. They are manufactured from proven, extreme-service tool steels for maximum wearability and toughness, according to the manufacturer. Manufacturing protocols developed by PDC insure precision flatness and exceptional edge profile uniformity. PDC blade assemblies operate dust-free, and eliminate “hairs” typical of spinning knife systems. PDC cutting blades are unique in their exceptionally long service life. The small, brittle, "spinning knives" that are commonly used by others dull quickly — often in days. In contrast, PDC blades deliver precise, clean cuts for months, even under continuous, high-speed conditions.
