Industrial Circular Perforation Knives for Precision Punching
Production Application
Perforating knives can puncture or cut various materials for a specific length. These knives cut vertical slots into materials at a given length and then keep your material together for another length. A perforating blades perf is measured by “cut and tie” where the cut is the size of the cut or perf, and tie is the length of the remaining material between cuts. Perforating knives often cut against a backing, like a metal cylinder or smooth blade, to form repeated cuts.
Paper: Perforation knives are used to create tear lines on materials like toilet paper, paper towels, napkins, and forms such as bills, notebooks, calendars, and stamps. These perforations make it easy for users to tear the items.
Packaging: Perforations make it easier for users to open packages, improving their experience and reducing frustration. In the food industry, perforated plastic packaging helps preserve products and reduce waste. Perforation blades are also used for tin foil and plastic wrap to allow for quick and precise tearing.
Function
Straight & Cutoff Perforating Knives: This perforating knife is one of the most commonly used blade styles for perforation. Senda can customize the geometry of the tooth to your industry and cut size. Popular cutoff blade designs include standard v-style, alternating hi-low tooth height, and vari-perf depth edges.
Circular Perforating Knives: Circular knives built for perforation can roll over a variety of materials to make a cut or perforation. This type of perforating knife isn’t as common. It remains, however, a superior choice for perforating various materials. In contrast to long knives, which get used for crosswise cutting applications, circular knives get used for lengthwise perforations.
