Unlike sheet metal slitting in the de-coiler, wire decoilers are machines that contains wire materials that usually do not require further processing like sheet metal. In most cases, the wire decoiler is used in conjunction with the wire straightening machine to make the entire production equipment play the best role.
Regarding wire straightening, when the wire passes through the wire straightening machine from wire decoiler, a rotating device or a roller is used to flex the wire in a different plane or direction. This flexing method just above the elastic limit of metal can reduce the residual stress as well as a straight wire exits the straightening tool as designed.
Wire straightening is widely used, and one of the high-end practices is for expensive metals such as jewelry. This method is also common in many household applications, such as TV antennas. In the metal forming industry, wire coiler and wire decoiler machines are used in the roll slitting process. This is a shearing operation that cuts large rolls of material into narrower rolls.
Wire decoiler machines can also be called uncoiler machines. There are two slitting methods, one is log slitting and the other is rewind slitting. In log slitting, the material roll is regarded as a whole unit, and one or more slices can be taken out without unrolling or rewinding. Another hand, in rewind slitting process, the material needs to be unwound and run through the machines knifes or lasers, and then rewound on one or more shafts to form a narrower rolls. When the diameter of the material is much larger than its width, multiple narrower strips of material can be called mults or pancakes.
Let's go back to the wire decoiling process of the metal wires on wire decoilers and look at the case of metal perforation. In Asia, many metal processing machines for perforation are manufactured. They can provide excellent quality while maintaining high output in a stable operating. Suppliers of perforated metal machines have developed different types of perforated metal machines 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.
In practical applications, perforated metal machine suppliers are always willing to provide technical advice based on customers' processing needs and help solve their production issues. There are a large number of perforated metal machine models on the market for users to choose, 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, high capacity, and the ability to create similar mesh patterns. In addition, the QDCS system can be used as very effective auxiliary equipment in industrial applications. Equipped with the QDCS system will enable the machine to achieve better performance at a lower production cost, coupled with the optional Quick-Die-Change-System, will greatly improve the overall production performance.
Wire decoilers can be applied to the plano type perforated metal machine on the production line according to the needs of the factory. In addition, the decoiler is not only widely used in plano type perforated metal machines, but also used in the production lines of angel bead and PLASTOR stop bead, brickwork reinforcing mesh machine, expanded metal machine, chain link fencing machine, barbed wire machine, razor barbed tape profiling machine, etc.
Perforated metal is also called perforated sheet, perforated plate, or perforated screen. It can be manually or mechanically stamped or punched to create a pattern of holes, slots. Regarding materials, materials used to manufacture perforated metal sheets include stainless steel, cold rolled steel, galvanized steel, brass, aluminum, tinplate, copper, titanium, plastic, etc. Such a manufacturing method of perforating metal sheets has been practiced for more than a century.
In the late 19th century, metal screens were used as an effective means of separating coals on many occasions. The first perforators used manpower to punch a single hole in metal sheet, which proved to be an inefficient and inconsistent method. This led to the development of new technologies, such as using a series of perforated metal needles to create desired holes or other shapes.
