Perforated Coil Industry Information
Perforated Coils
Perforated coils are widely used as enclosures, sign panels, partitions, safety guards, and screens. These coils are manufactured through an efficient production line that makes the production time quicker by eliminating the laborious handling of sheet material sections. These lines are best used where there is a demand for high volume or big lots of perforated material, making them a great option for Original Equipment Manufacturers with large and automated production lines.

Manufacturing Process of Perforated Coils
Perforated coils are manufactured by perforating an entire line of flat rolled sheet metal continuously and winding it back to form a uniform coil. These coils are made in a structured production process that is best called a perforation line or an industrial perforating press.
The main components that make up a perforation line are:
- Unwinders with Straighteners
- Punching Press
- An Industrial Grade Shear
- A Recoiler
These components work systematically together to fabricate a perforated coil in the most efficient way. First, the unwinder, equipped with a straightener, will flatten the material and feed it into the machine’s feed rollers. The punching press contains predefined dies or molds that are used to punch and create the holes for perforation. Finally, when the desired length of the coil is achieved, the punching system will come to a halt and be cut by the specially designated shear for cutting the coils. These coils will be cut depending on the established requirement set by the customer or the client. If they desire a whole coil to be perforated, the coils will not be cut and will then proceed to the rewinding process.
Benefits of Using Perforated Coils
There are benefits to using perforated coils as materials. The first one would be the coil’s ability to perforate long coils instead of just sections of sheets. This will greatly contribute to the cost reduction on the raw materials brought about by bulk production. Another benefit, resulting from this, is the shortening of the production time due to its systematic and continuous perforation line. This promotes overall efficient use of resources and lessens labor.
Factors to Consider When Purchasing Perforated Coils
Something to take into account when purchasing perforated coils is the expense. Starting a perforation line is highly expensive because of the costly molds and die needed for the punching process. Some companies, or manufacturers, find it too high of a cost to fund this type of production. Besides the cost concerns, customization of holes would be another factor to consider for this type of perforation. The pattern and shape of holes will only be limited to the available dies and molds that the manufacturer has. Lastly, material wise, the capability of the perforation line is limited to a low to medium material thickness. In this case, sheet perforations are preferred for thicker and heavy applications.
