Steel Strip Slitting Line

Steel strip slitting lines are widely used in various sheet metal forming lines in the global industrial field. In the metal processing industry, there are two main models. One is very familiar metal cutting, such as mechanical turning, milling and drilling or other tool cutting processes. Another model is metal forming, such as slitting, pressing and stretching.


What Is Slitting?

Metal forming is a forming process that gives new forms of raw materials. Slitting is a shearing operation that cuts large rolls of material into narrower rolls for users to use. There are two types of slitting, one is log slitting, and the other is rewind slitting. In log slitting, one or more slices can be taken out without unrolling the material roll. In rewind slitting, the material roll needs to be unwound and run through the cutter or laser on the machine, and then wound on one or more shafts to form a narrower roll.


Relationship between Workpiece Materials and the Slitting Line

Smart slitting is like any other subjects in the industry now. Slitting specifications are complicated, and the specifications vary, yet the arrangement is different.
 
If the slitting material is soft such as plastic films, textiles, adhesive tapes, and paper, the slitting tools may include razor blades, straight blades, or circular blades. Some blades cut into the material, while others crush the material against the hard roller. In addition, the cutting blade can be set to the desired width. Sometimes one machine has several blades, can produce multiple output rollers at a time, and rewind the cut material on a paper, plastic or metal core on the exit side of the machine.
 
This slitting method is cost-effective, high-precision, and can be used for mass production, and some machines have the function of monitoring and trimming the blade to maintain the quality and accuracy of the cut at any time.


How Do Steel Strip Slitting Lines Work?

During the rewind slitting process, the steel strip roll is first unwound and passed through the cutter or laser on slitting machine, and then wound on one or more shafts to form a narrower roll. In fact, if the diameter of the material is much larger than its width, then multiple narrower strips of material can be called multiple or pancakes.

On the other hand, for hard material slitting, such as sheet metal materials, blades cannot be used as a slitting tool, but a modified shearing method must be applied. Using two cylindrical rollers with matching ribs and grooves to cut a large roller into multiple narrower rollers, this continuous production process is economical and precise. Such shearing method is even more precise than most slitting techniques.


What Are the Features of Steel Strip Slitting Lines?

The steel strip slitting lines benefit the potential forming process of the steel strips with the special features this mechanism has. Only when the slitting lines help cut the steel strips into appropriate sizes then the following procedures can be made sure smooth and efficient.


● Cost-effective

Since the slitting mechanism is simply applied for cutting the steel strips, it doesn’t require complex operating techniques. Therefore, the formation of the mechanism is relatively simpler than many other machining processes. This lowers the costs the slitting lines take during operation.


● High-precision

Despite the lower costs the steel strip slitting lines take, they can still ensure high-precision when they are applied. With the proper setting of the cutting blades and workpieces, the separated steel strips are ensured the same width, which make sure the high-precision feature of the slitting lines.


● High productivity

Nowadays, the steel strip slitting lines are usually added with computerized control in the operation method. As the entire process is controlled by the computerized technology, the slitting lines can work unattended, which reduces the circle time during operation. This not only enhances the high-precision cutting process, but also brings high productivity in the long term.


Conclusion

Through different processing, metal plates can be used to make a variety of very useful products. Depending on the thickness and material, sheet metal can be created with a variety of shapes and textures. These industrial or daily necessities are mass produced, and rapid manufacturing is the key to mass production. Therefore, the slitting machine, cutting machine and other metal forming machine all need to be integrated with an automated system.
