Hydraulic Decoiler

Hydraulic decoilers are decoilers designed and developed for heavy duty and steady pace working steps, especially for certain specific purposes for the production lines. In the field of metal forming, coiler and hydraulic decoiler machines are widely used for roll slitting, which is a shearing operation that cuts a large roll of material into narrower rolls. Roll forming begins before the process, and then cut to length machine and hydraulic decoilers work together.

Hydraulic decoilers can also be called the uncoiler machines. There are two slitting methods, one is log slitting and the other is rewind slitting. In log slitting, the roll of material is treated as a whole unit after the roll forming, and one or more slices can be taken out of it by the cut to length process without unrolling or rewinding. In rewind slitting, the web will be unwound and passed through knifes or lasers of the machine, and then rewound on one or more shafts to form narrower rolls, resulting in better quality.


Modern Manufacturing

In the era that nuclear fusion technology has made significant progress, corresponding heavy duty metal working machineries and equipment have also been greatly promoted and are widely used in manufacturing. In the field of metal perforation, Taiwan made perforated metal machines can provide excellent quality and increase output while maintaining a stable operating on the production lines.

Suppliers of perforated metal machines manufacture different types of perforated metal machines, and through continuous improvement of the feeding mechanism and punching moulds, their machines can meet the processing needs of customers for different perforation patterns and perforated metal applications. Perforated metal machine suppliers are always happy to provide customers with technical advice based on their processing needs and help optimize their production process. Roll forming for their customers’ materials shall also be considered in this process.

There are a large number of perforated metal machine models for users to purchase, such as plano type and C type perforated metal machines. For plano type perforated metal machines, they are most suitable for installation in massive production lines. These models focus on high speed, large capacity and production of similar mesh patterns. Hydraulic decoiler hydraulic coilers are two supportive units in the production lines.


Perforation and Decoilers

For metal perforation to be processed, many support devices are usually used in the metal processing industry. Roll forming device is one of them. Metal perforation, by definition, is a metal sheet  processed by hydraulic decoiler which is formed by roll forming or coil punched with precision holes. Many perforated metal machine suppliers are able to provide perforated metal with round, square, slotted or custom-shaped holes with special requirements to meet customers' various uses. Perforated metal mesh products have been widely used in filtration, mechanical protection, sound insulation, and construction. Some suppliers may provide optional auxiliary facilities or accessories, such as leveler, de-coiler, flattner, roll forming, cut to length equipment, and recoiler machines.

With a good leveler, the plano type perforated metal machine can produce metal mesh without the product defects that may occur in conventional production lines. During the perforated metal processing, uneven or sloping edges sometimes occur. These product defects cause losses to the manufacturer. By using a leveler, for manufacturers, the above issues can be solved well.


Control of Hydraulic Decoilers

Programming control is the most commonly used mechanical control manner in the field of metal processing. Manual decoilers in the metal forming industry are also commonly used due to their flexibility and versatility. The role of roll forming here is important. In the field of metal working, business owners can choose two slitting methods according to their operation models. The first is log slitting, which is very common, and the other is rewind slitting.

Regarding log slitting, the roll of material is treated as a whole piece, from which one or more slices can be taken out without unrolling or rewinding. In rewind slitting, the roll of material will be unwound and passed through the machine's knifes or lasers, and then rewound on one or more shafts to form narrower rolls. In some cases, multiple narrower strips of material may be called mults.  

In order to make the coiling and de-coiling run smoothly, the operation of the hydraulic mechanism must be very strict and accurate. Therefore, the way manufacturers handle hydraulic units or other power sources is critical to the final output and quality. In the metal forming process, many machine operators prefer the super high technology CNC control system covering the entire manufacturing module so that they can operate in a more relaxed manner. In the era of pursuing intelligence, we know that the future of the former is much more developed by the institutions in their labs all over the world.
