If you are looking for any machine that will run with a coil, then there is no doubt that you need an uncoiler or an uncoiler.
Investing in capital equipment is a task that requires you to consider many factors and functions. Do you need a machine that can meet current manufacturing needs, or do you want to invest in next-generation features? These are the questions that shopkeepers always ask themselves when buying a roll forming machine. However, research on uncoilers has received little attention.
If you are looking for any machine that will run with a coil, then there is no doubt that you need an uncoiler (or sometimes called an uncoiler). No matter you have a roll forming, stamping or slitting production line, you need an uncoiler to unwind the coil for the next step; there is really no other way to do it. Ensuring that the decoiler meets your workshop and project needs is critical to maintaining the shape of the roll forming machine, because without the material, the machine will not run.
In the past 30 years, the industry has changed a lot, but the uncoiler is always designed according to the specifications of the steel coil industry. Thirty years ago, the standard outer diameter (OD) of steel coils was 48 inches. As the degree of customization of the machine is getting higher and higher, and the project requires different options, the adaptability of the steel coil is 60 inches, then 72 inches. Nowadays, manufacturers occasionally use coils larger than 84 inches. in. Coil. Therefore, the decoiler must be adjusted to adapt to the constantly changing outer diameter of the coil.
Uncoilers are widely used in the rolling industry. Today’s roll forming machines have more features and functions than their predecessors. For example, 30 years ago, the operating speed of the roll mill was 50 feet per minute (FPM). They can now run up to 500 FPM. This change in roll forming production has also improved the capabilities and basic range of decoiler options. It is not enough to choose any standard decoiler. Many factors and functions need to be considered to ensure that the workshop needs are met.
The decoiler manufacturer offers a variety of options to ensure that the roll forming process can be optimized. Today’s decoiler weighs 1,000 pounds. Over 60,000 pounds. When choosing a decoiler, please keep the following specifications in mind:
You also need to consider the type of project you will be working on and the materials you will use.
It all depends on what you want to run on the rolling mill, including whether the coil is pre-coated, galvanized or stainless steel. These specifications will determine which decoiler features you need.
For example, the standard decoiler is a single-ended decoiler, but having a double-ended decoiler can reduce the waiting time for material handling. With two spindles, the operator can load the second coil onto the machine and process it whenever needed. This is particularly useful when the operator constantly needs to replace the coil.
Manufacturers usually don’t realize the practicality of the decoiler until they realize that the decoiler can perform six to eight or more replacement operations per day. After preparing the second coil on the machine and waiting for the machine, there is no need to load the first coil with a forklift or crane immediately. The decoiler plays a vital role in the roll forming environment, especially in mass production, where the machine may require eight hours of shifts to form parts.
When investing in a decoiler, it is important to understand the current specifications and features. However, it is also important to consider the future use of the machine and what future projects may be on the rolling mill. These are all factors that need to be considered accordingly, and they really help determine the right decoiler.
The coil car helps to load the coil onto the mandrel without waiting for a crane or forklift to complete.
Choosing a larger mandrel means you can run a smaller coil on the machine. Therefore, if you choose 24 inches. Spindle, you can perform any other operations. If you want to jump to 36 inches. Option, then you need to invest in a larger decoiler. It is important to look for opportunities in the future.
As the coils are getting bigger and heavier, safety is the main problem in the workshop. The decoiler has large, fast-moving parts, so operators must be trained in machine operation and correct settings.
Today, coils can range from 33 to 250 kilograms per square inch, and uncoilers have been modified to meet the requirements of coil yield strength. Heavier coils pose greater safety challenges, especially when cutting belts. The machine includes a compression arm and a buffer roller to ensure that the roll is only unwinded as needed. The machine can also include a paper feed drive and a side shift base to help center the web for the next process.
As the weight of the coil increases, it becomes more difficult to manually expand the mandrel. When the workshop moves the operator from the decoiler to other areas of the workshop for safety reasons, hydraulically expanded spindles and rotation capabilities are usually required. A shock absorber can be added to minimize the abuse of the decoiler’s rotation.
Depending on the process and speed, other safety features may be required. These features include an outward coil holder to prevent the coil from falling, a monitoring system for coil outer diameter and RPM, and unique braking systems such as water-cooled brakes for high-speed running pipelines. These are very important and help to ensure that when the rolling process stops, the decoiler also stops.
If you work with materials of multiple colors, you can use a special decoiler that provides five mandrels, which means you can place five different coils on the machine at once. The operator can make hundreds of one color and then switch to the second color without spending time unloading the coil and switching.
Another feature of the coil car is that it helps to load the coil onto the mandrel. This ensures that the operator does not have to wait for a crane or forklift to load.
It is important to spend time researching the different options available for the decoiler. With an adjustable mandrel to accommodate coils of different inner diameters, and a variety of size options for the coil backplane, you need to consider many factors to find a suitable fit. Listing current and potential specifications will help you determine the necessary features.
Roll forming machines, like any other machine, make money only when they are running. Choosing the right decoiler for your store’s current and future needs will help your roll forming machine run more efficiently and safely.

The HD-FS 3015 2kW laser in our showroom has been tested! Please note that in some cases, we use workshop air in Access Machinery to cut steel and alloys, even if the cutting quality of these steels and alloys is not as good as nitrogen. We discussed how almost every manufacturing industry has produced workshop air that can be used to significantly reduce laser operating costs and gain a competitive advantage.
