Rotary Perforation Roller Needle Perforating Shaft Pin Cylinder Needle Segments

Cold rotary pin perforating
Cold pin perforating is the process of taking a sharpened pin and piercing a substrate with the pin point. This usually results ina "volcanic" looking aperture in poly- based materials, which can be beneficial in some applications, such as those that require aone way valve. Cold perforation is the least expensive and fastest methods of perforating.
Cold rotary pin perforating can be applied continuously, or can be made to work in register or intermittently.

Benefits:
Least expensive method of perforating
Fastest method of perforating
Simple to install and operate
Simple to maintain
Can be used on just about any material

Disadvantage:
Some benefits from a volcanic style apertureDusting can occur in some materials
Punctured hole can potentially close back up, but will open again in above normal atmospheric conditionsCold pin perforators canbe made from 25mm wide up to 4000mm wide as standard

Hot rotary pin perforating
Hot pin perforating is the process of taking a heated, sharpened pin and piercing a substrate with the pin point. This results ina melted hole, where the center of the hole is melted into a re-enforced ring around the punctured hole.

Benefits:
Less expensive method of perforating than laser with often similar results
Great for perforating all the way across a web
Straightforward to install and operate
Simple to maintain
Heat helps prevent dusting seen in cold perforating applications
Can be used on just about any material
Some benefits from the molten ring style aperture
Stronger resulting holes are helpful, especially in brittle material applications
Melted hole will not close back up, and allows for excellent flow control of air, moisture or water

Disadvantage:
The center of the hole is pierced and melted, debris can sometimes be an issue, depending on the substrate
The welted style hole is not always suitable for the application
