What is Coil Binding?

Plastic single coils are spiral coils made of plastic products. They are generally used for binding books and calendars.

Plastic single coil

Plastic single coils are mainly divided into three categories in the bookbinding equipment industry: polyethylene resin (PE5000S), polypropylene resin (PP), and polyvinyl chloride resin (hard PVC). Among them, polyethylene resin (PE5000S) and polyvinyl chloride resin (hard PVC) have the largest market circulation. Due to the softness of the polyethylene resin (PE5000S), it is difficult to handle manual binding and the production efficiency is very low. The factory also faced difficulties in recruiting or high wages, and slowly began to withdraw from the market; only the "hard" characteristic of rigid PVC single coils reflects its easy processing and easy operation, thus achieving ^[1]

The plastic single coil is mainly customized according to the actual samples provided by the customer. If the customer does not have the actual samples, they can also be based on the digital color pictures, books, books, albums, etc. Card) to customize colors.

Our factory provides 45 specifications, from 6mm inner diameter to 50mm inner diameter (with 1mm as a specification). It is suitable for binding thickness from 3mm to 46mm. To judge the tooth pitch, the conventional tooth pitches of our factory are 5mm, 6mm, 4: 1 (6.35mm), 3: 1 (8.47), 10mm. The most conventional tooth pitches are still 6mm and 3: 1.

The plastic coils produced by our factory are of high quality, and the control of the wire diameter and inner diameter is very precise. The thickness of the drawn wire is very uniform, and the phenomenon of thick and thin will not appear.
