Plate Leveling Machines

Plate Leveling Machines

Vistmac develop Sheet Metal Levelers machine in order help customer supply precision sheet metal processing solution.Plate levelers are most often used for leveling thin or heavy gauge materials. Typically, they have individual roll drive, along with individual roll control. Closed loop positioning allows the leveler to generate machine setting recipes for common plate runs.Vistmac can supply different thickness, different width plate straightening machine.


1. Why level metal sheets?

Unleveled sheets can cause errors during downstream processes such as bending. This can increase the amount of rework and rejects. Preparing unleveled material for welding is also highly work intensive. When using welding robots, materials like these also have a negative impact on the process reliability and increasing welding times. This, in turn, results in higher process costs as well as increased thermal stress on the material. The immense heat creates internal stresses in the material and the entire welding assembly deforms. The consequence: rework, longer production times as well as inefficient workflows.

A leveler can prevent precisely these problems. Utilizing the mechanical process of roller leveling, the machine significantly reduces unevenness in the material. This procedure is especially suitable for quickly and effectively leveling sheets/parts as it doesn’t only reduce the unevenness but also the internal stresses in the parts through a process of bending and counter-bending. Your company can benefit greatly from automated leveling. Through standardized and automated processes, roller leveling guarantees consistently high quality and calculable results.

The most obvious reason for leveling is to fabricate flat metal sheets. Not only when the component itself requires it, but also because the people responsible for the downstream processes will thank you for it. For example, the welder or the person operating the press brake. In addition, most companies aim to utilize standardized and predictable processes to fabricate parts. As a consequence, they rely on the sheet metal working process running without any problems.

That is why the decisive factor when selecting a leveler consists of the processes that customers want to improve and what aim to achieve by leveling the sheet metal. Their planning defines the framework for the design of the leveler and determines which machine options make sense.

Welding is a good example. Practical experience has proven that using leveled sheets drastically reduces the assembly time of the welded assembly. In addition, the dimensions of the assembly are more accurate and there is no need for reworking. This is why leveled parts are indispensable for the efficiency of work processes. In view of this, the requirements of the welders or the welding robot should always be taken into consideration when selecting a leveler. This is the only way for a company to deliver the best possible results.

2. What is the most important area of application?

To find the right leveler for sheet metal parts, four questions for the leveler supplier have to be answered:

*Who are the main customers (including internal customers)?

*Which spectrum of sheet metal parts is primarily processed?

*How large does the machine have to be?

*What criteria apply for the sheet metal?

When choosing the right leveler, it is important to clearly define which aspects the machine needs to cover. Does the machine only need to handle a small range of tasks yet perform these particularly well and efficiently? Or is it more important to flexibly handle a large range of the components and their requirements – even if you have to do without one or the other additional machine feature?

It is also important that the leveler used for sheet metal has certain properties. The standard on modern precision levelers includes the block design of the leveler, the correct roller layout and support along with the number and the diameter of the leveling rollers. The larger the diameter of the rollers, the larger the straightening range. Furthermore, small rollers and small spacing between the rollers is extremely important to meet the demanding flatness requirements. In addition, the leveling rollers themselves require very good support to ensure that the panel is continuously rolled and cannot slip between the individual rollers and buckle. Different machine designs are worth considering, depending on the sheet metal requirements. These include intermediate rollers to prevent possible impressions on the sheet metal. Other options may be important when leveling materials with sensitive surfaces or to avoid deformation of the part edges.

3. How to get the quotation about plate leveler machine?

*What’s the material you want to leveling? Tensile strength and Yield strength ?

* What’s you max sheet size ? length and width ?

*What’s your max thickness sheet?

*what’s your product application ?
