Material of 100-300mm Z Purlin Forming Machine
1. Roller: bare steel with heat treatment to ensure the hardness of roller reach HRC60.
2. Active shaft: high grade No.45 carbon steel to improve the integrated mechanical performance of the shaft.
3. Electric elements: PLC control panel, with the transducer imported from Mitsubishi. Other elements are purchased from famous suppliers in China
4. Cutter blade: Cr12 tool steel with quenching treatment.

100-300 Z Purlin Forming Machine Component
1. Cantilever hydraulic expansion decoiler
2. Coil feeding device
This feeding device is used to ensure the sheet placed at the right place. The steel sheet is manually fed to the levelling device.
3. Levelling device
The levelling device consists of 3 upper rollers and 4 lower rollers. It is designed to make the steel strip move into the cutting device flatly and straightly.
4. Pre-cutting device
The cutting operation is driven by the power of hydraulic station, ensuring the precision of cutting.
5. Roll forming system
(1) Rollers: bare steel with heat treatment to ensure the hardness of roller reach HRC60.
(2) Roller axis: high grade No. 45 carbon steel to improve the integrated mechanical performance of the shaft.
7. Electric system
Two motors are used to supply power to meet the power requirements of this Z purlin making machine.
8. Hydraulic station
It supplies power to the cutting device. When it’s not cutting, the station will automatically shutoff to save power.
9. PLC control panel
The control system of our Z purlin forming machine is imported from Mitsubishi.
10. Runout table
It supports the finished panels. Generally, it can support 2 pieces of 20000mm panels.

100-300mm Z Purlin Forming Machine Working Flow
Decoiling → levelling → punching → measuring length and cutting the sheet → roll forming → conveying to the runout table
