Our most common double-coil binding is the binding of the notebook. The advantage of this binding is that it is not only beautiful but also very convenient for writing. So what are the benefits of binding the double coil? What should you pay attention to when choosing?
The double coil is a two-strand steel coil with preset dimensions and specifications. The common materials are divided into spray steel ring and plastic coil. Usually, round holes or square holes are made on the left or the top of the printed matter. After the YO double coil is passed through and the YO ring binding machine is pressed and fixed, the entire binding process is completed.
When selecting a coil, it is necessary to pay attention to its quality. Some coils may cause cracks during binding because the surface plating plastic layer is not strong enough. If the coil is too thin, there may be problems such as unstable binding. After the coil is locked, the page cannot be added unless the coil is removed. The cost of double-coil binding is higher than that of a single coil. Of course, the binding effect is better and more durable. With a two-coil binding book, you can fully lay out any page while you read, making it easy to read and search. Books with a thickness of 30mm or less, such as tool books, technical manuals, recipes (recipes), VIS manuals, and architectural drawings, are most suitable for this type of binding.
The advantages of binding double coils are very obvious. Not only is the binding fast and effective, but also it is very convenient to use. More and more print production companies choose to bind the double coils.
