Office Supplies Metal Wire Binding Coil

Spiral binding plastic coils are one of the most popular traditional binding methods available. They consist of a continuous spiraled coil that is made of durable and flexible plastic and is rolled into holes along a binding edge. Spiral binding coils offer a modern bookbinding alternative when compared to traditional plastic comb spines, while still being affordable and easy to use.
Another benefit of spiral binding coils over many other binding methods is that coil-bound books have the ability to flip pages completely around a full 360 degrees without damaging the contents, so they can lay flat and stay flat. This allows your book pages to flip all the way around from front to back for easy readability. The spines also bounce-back to their original shape, even after heavy use and bending.

1)Choose a Coil Size (Diameter)?

Now choose your coil size (diameter) for your document. You can use the coil bind capacity chart below to help choose the best size based on your stack thickness or your sheet capacity. Just note that the sheet capacity was calculated using sheets (not pages) that were all 20 lb. bond copy paper, without any covers; this means it can vary significantly depending on the stock you are using, which is why we recommend the stack thickness method instead. And remember: having a coil that is slightly too large is better than having a coil that is too small; a small coil won't allow pages to flip smoothly and can pinch them, tear more easily. So if you are between sizes, we recommend you size-up.

 


Take the pages and covers being bound and lay the stack flat on a table. 
If you want an alternative solution to choose the best size, you can utilize this general rule of thumb:

  1. Measure the thickness of the stack, but don’t press down; let it lay naturally loose.
  2. Add 1/8" to the stack thickness - that will be the size of the binding coil recommended for your document thickness.

2) Choose a Coil Pitch ?
Spacing refers to the number of holes per inch or the spacing of holes. It's reflected in a ratio that includes the number of holes, a punctuation colon, and then an inch measurement. For example: 4:1. This ratio is read aloud/pronounced "four to one" and means 4 holes per 1 inch of length.
The 4:1 pitch bundled coil spine is by far the most popular, with approximately 98% of customers ordering the 4:1 pitch screw binder. 5:1 is a special pitch made primarily for print shops with specialized equipment for punching and for users who may have machines made in certain countries where 5:1 pitch is more common. Some more specialized machines will have other coil hole patterns such as 3:1, 2.5:1 or even 2.231mm. Before buying a screw binder, you'll want to check the compatibility of your screw binder, but keep in mind that most machines are 4:1.

Advantages and disadvantages of spiral binding

We already know that coil binding is one of the most popular methods on the market in 2022. They are commonly used in brochures, reports, financial statements, manuals, calendars, cookbooks, children's books, marketing materials, and more. But why do they have the largest market share in the bookbinding industry? In this quick overview, we'll show you the pros and cons of this classic document binding spine solution.
benefit
DURABLE AND FLEXIBLE - The coils are made of nylon covered wire, which is very flexible and durable. This means they can bounce and bend and still return to their original shape. This makes them extremely durable and resistant to damage that could compromise the presentation and functionality.
EASY TO CLEAN AND SANITIZE - The nylon covered wire material can be easily cleaned and sanitized with any liquid cleaner of your choice. This nylon-coated thread can be easily air-dried and reused by newcomers without fear of the spread of bacteria and viruses. If you plan to clean and reuse your coil book, make sure you also protect your pages by laminating.
Page Turning 360° - Turning pages is more convenient because they can turn the sheets all the way so that they are placed back to back.
Affordable - Coil bound spines are very affordable for users of all budgets.
Available in a variety of lengths - can be cut to any length to match your product.
Rich Colors - In addition to a variety of colored coils, including black, white, clear, navy, blue, maroon, red and forest green, all can be customized.
limit
Metal Spiral Coils, Color Type - Some users have a small number and plastic coils, such as double loops, are recommended.
Insertion Issues - Depending on the equipment available, inserting the coil can be a bit of a hassle for some users. Especially for thick books with large diameter coils, rolling the helix through all those holes can take some time and fiddling.
3 STEP PROCESS - Some bindings like wire and comb have 2 steps; simply punch and bind. However, there are 3 steps to the coil; punch the hole, insert the coil, and crimp the end.
There is no perfect registration - due to their helical design (and angular rotation), coils are not the best choice for projects that require tight registration on spreads, where the pages do not line up perfectly from one side to the other The other side.
