Spiral coil crimping pliers are used to finish binding documents with spiral coil. They cut off the excess coil and bend the ends over in a single motion, helping to ensure that the spirals don’t spin back off the book. Usually, spiral coils are purchased longer than the edge of the document you are binding. Most spiral coils are purchased in lengths that are approximately 1″ longer than your finished binding edge, allowing for the crimping process. Special crimping pliers makes the finishing process much easier, preventing you from having cut off the coil and then manually bend the end over so that it will stay secure. Features:     These pliers are marked with a red dot on one side, helping you align the pliers during the crimping process. It is also important to note that the red dot should always face the ceiling, and keep the spine of the book facing toward you when you are crimping coil. Spiral Coil And Crimpers also offer a standard throw length, or length of the piece of coil that is bent over, which is ideal for 4:1 pitch and 5:1 pitch coil – the two most common sizes.

In addition, the plastic coated handles of these pliers make them easy to hold and easy to use.  steel coil Limitations:     Although the throw length of the pliers is ideal for standard 4:1 pitch and 5:1 pitch binding., trying to bind documents with 4:1 pitch oversize oval holes, 3:1 pitch holes or 2.5:1 pitch holes will be difficult. With larger holes the throw length may not be long enough. This could allow the spiral coil to spin off the book. For these applications, premium oversize oval hole crimping pliers are suggested. The pliers must be squeezed hard enough to bend the end of the coil over but not so hard that you cut the end off. This can take a bit of finesse, and those who work with high volumes sometimes find the coil crimping process tedious and labor intensive. In this case, there are several automated crimping tools available on the market, but they can range in price from a few thousand to tens of thousands of dollars and often require significant amounts of setup time. Some new coil binding machines now include a small crimping tool on the machine itself and are easy to use, but are also very expensive.

They may be a good alternative, however, for those who dislike crimping documents with these pliers. Recommendation:     Anyone who uses a coil binder should have a pair of coil crimping pliers, so if your machine doesn’t’ come with a pair, it is highly-recommended that you include one in your order. Although high-volume users may consider other crimping options, it is best to consult with a document finishing specialist before deciding which option will work best for your application. And don’t forget – customers who use non standard pitches or oversize oval hole pattern should consider a pair of pliers with a longer throw for the best effect.

Hygiene and SafetyNormally, metal in good condition has a smooth surface, making it very easy to clean. Rust spots cause the metal to become pitting, increasing the surface area by a surprisingly large amount and providing space for unwelcome bacteria and microbes to breed. This is particularly undesirable for cutlery and cooking implements. Where cutting tools are concerned, rust can be very dangerous. These tools carry the risk of piercing the skin, or may even be designed for this purpose for example in the case of surgical scalpels. Tetanus is a major problem associated with rust – though it does not directly cultivate the tetanus bacterium, it does provide a prime habitat for it. Stainless steel surgical implements totally avoid this issue by being rust-proof.This wonder metal has been specifically designed with rust-resistance in mind. It is formulated as an allow of chromium and steel. Generally the metal contains only 10-15% chromium, but this is enough to provide immunity against oxidation by the color coated steel coil manufacturers usual combination of water and oxygen.

The chromium in the metal forms a protective film of chromium oxide, which effectively blocks iron oxide from forming and spreading destructively deep into the material.FlexibilityBecause stainless steel is rust resistant, it can be used in a variety of ways that are impractical or expensive with ordinary steel. Piping is a great example. Many pipe systems can get away with using PVC and copper. For lower volume needs at low to moderately hot temperatures, these work perfectly well. For a system under greater stress from constant high temperatures and high volume, steel is a more durable choice. Stainless steel is perfectly suited for the job as it combines the strength and high melting point of plain steel with corrosion resistance that means the insides of pipes stay in working order for many years. A food processing plant, for example, would greatly benefit from the hygiene benefits of stainless steel pipework.Environmental ConsiderationsUse of metals can be considered more environmentally friendly than many plastics due to the ease with which they can be recycled.

Though it is not biodegradable, stainless steel can be melted down to be reused.Aesthetic ConsiderationsAside from the numerous hygiene and durability benefits, stainless steel is also very pleasing to look at. The chrome/iron combination leads to a pleasingly shiny, bright surface and of course the corrosion resistance ensures that the surface stays as good as new. This makes the material particularly desirable for any item that is on display in the home or in the workplace. Altogether, stainless steel presents a combination of strength, aesthetics and hygiene that make it a superb choice for tools, containers, machinery and countless other applications.
