Perforated metal sheets have many small holes of round, lozenge, square, triangle etc. in the plates, they are usually stamped by stamping machines with stamping dies. The perforated metal sheets, metal meshes have been widely used in daily life and industry area, such as sieves, baking trays, outdoor furniture, ceilings, noise reducing fence, dust gauge, vegetable matter, window blinds etc.
It should be very flat of the perforated metal sheets, but it will get curved and out of shape after stamped, so how to get them to be very flat? It has to be processed by metal plate leveling machines, so this article will introduce you some models of our precision perforated metal sheet leveling machines.
There are some model leveling machines used to process perforated metal sheets: JZ32-S series, JZ42-S series, JZ60-S series etc. (these are models of manual adjust leveling roller gap), JZ30-Z series, JZ40-Z series, JZ50-S series etc. (these are models of manual adjust leveling roller gap).

Equipment process principle
It equips with a few groups of leveling rollers and backup rollers arranged in multi-layers and a very small spacing between each other. When metal blanks go through the precious leveling machine, based on “Bauschinger effect”, metal blanks were repeatedly twisted to make metal fiber gradually consistent, eliminate internal stress, restore and improve the flatness of work-pieces, so as to get ready for the subsequent process such as bending, welding and other processing procedures.
 
It's working site of 0.6-0.8mm thickness perforated metal mesh leveling site in the video, machine model in the video is JZ30-1300Z model, equipping with φ30×21pcs leveling rollers (upper 10pcs/lower 11pcs), specialized on thin metal parts leveling and processing, such as thin perforated metal sheets, thin metal blanks etc.

It’s electric to adjust leveling roller gap and straightening performance. It equips with SIEMENS PLC, SIEMENS HMI, DELTA servo motor+ DELTA servo driver for electric adjusting leveling roller gap, DELTA inverter for main motor. Just need to set leveling data in the SIEMENS HMI’s main page, then it can automatically adjust leveling roller gap, very intelligent and easy to operate.
It can add motorized roller type conveyor belts or PVC type conveyor belts both at entrance and exit (OPTIONAL PART). For light metal parts, it can adopt PVC type conveyor belts, on the contrary, for heavy and large size metal parts, it’s better to adopt steel roller type conveyor belts. They are used to carry metal part from entrance part and easily entering leveling machine and then carry out metal parts at exit.

Motorized roller type conveyor belt size (W×L×H): about 1900×1650×800mm/set (or as designing)
Conveyor belts main components: Steel roller type conveyor rollers, steel support base, main motor with speed reducer, transmission chains etc.
Main motor: AC2.2KW (or as designing)
Conveying speed: 1-15m/min (speed adjustable, equipping with speed controller)
