Perforated edge file cards series#
Perforation frequently refers to the practice of creating a long series of holes or slits so that paper or plastics can be torn more easily along a given line: this is used in easy-open packaging.
The laser perforation is often carried out on roll slitting machines (slitter rewinder) as the printed material is slit down to the finished roll size. This is very important in modified atmosphere packaging for fresh produce. The big advantage of laser perforation is the consistency of the hole size, compared to mechanical perforation. Laser perforations look similar in many respects to hot needle perforations. Laser cutting can place many precise holes in a web.
Ĭommon applications are fruit and vegetable bags, hole punching and ticket punching. Burrs are produced on the side of the workpiece that is against the die. The clearance (the distance between the outside circumference of the punch and the inner circumference of the die) must be properly maintained to ensure a clean cut. The punch and die are shaped to produce the desired shaped hole. The middle section of the workpiece is scrap commonly known as the chad in paper and similar materials. The workpiece is sheared by pressing (either by machine or hand tool) the punch through the workpiece and into the die. Hot needle perforation also assists when high density pin patterns are utilized, as the heat aids the perforation of the material.ĭie and punch sets can be used for thicker materials or materials that require large holes this process is the most common for metalworking. Hot perforation melts a hole in the material, causing a reinforced ring around the hole. The solution to this is often heating the pin i.e. In more brittle films, cold perforation can cause slitting rather than creating a round hole, which can jeopardize the material's integrity under pressure. Pinned rollers can be made from a variety of materials, including plastic, steel, and aluminum.
In materials that have elasticity this can result in a "volcano" hole that is preferred in many applications. There are a handful of manufacturers that specialize in hot and cold needle perforation tooling and equipment. Cold perforation tools include needle punches. The pins or needles can be used cold or heated.
