Double-loop binding related knowledge points
Our most common double coil binding is the binding of the notebook. The benefits of this binding are not only beautiful but also very convenient for the writing of the notebook. What are the advantages of binding the double coil?
The double coil is a two-strand steel coil that is pre-set with good dimensions and specifications. The common material is divided into sprayed steel coil and plastic coil. A round hole or a square hole is usually punched on the left or right side of the printed product. After the YO double coil passes through, the entire binding process is completed after the YO loop binding machine is pressed and fixed.
When selecting the coil, it is necessary to pay attention to its quality, and some coils may cause cracks during binding because the surface plating of the plastic layer is not firm enough. If the coil is too thin, problems such as loose binding may occur. After the coil is locked, no more pages can be added unless the coil is removed. Double coil binding costs more than a single coil, of course, better binding 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. The double coils we produce are of superior quality. If you need them, please contact us.
