Double layer roll forming machine for metal roofing and wall panels is capable of producing two different types of metal roofing or wall panel profiles on a single machine. Typical profiles include trapezoidal roofing sheets and corrugated panels. This model is one of the most popular choices for general construction projects involving wall cladding and roofing systems, such as industrial workshops, warehouses, commercial buildings, and steel structure projects.

How do we Manufacture Double Layer Panel Roll Forming Machine
Machine Body Parts
1. Guide Device
Feeding material guide device, use high speed steel on both sides;
Its feature of high hardness, high wear resistance and high heat resistance to guarantee long life.
2.High Accuracy Shafts
Solid shafts dia. 72 mm for material thickness.
All shafts are tooled twice by cylindrical grinding machine to ensure final precision.
Guarantee buyers get high accuracy deck sheet from Zhongyuan made machine.
3.Rollers Of Machine
Each forming roller use CNC machine to polish and machining into designed rollers shape,it can improve rollers accuracy.And planted 0.03-0.05mm hard chrome to make sure machine running more than 15years+ for you.
Design Bearings Inside Forming Rollers
Design bearings inside the rollers to allow machine run with less loading so that rollers not easy to damage.
Ensure the same speed between all the rollers, no speed difference between rollers, improve the forming accuracy.
Bearings are helping to prolong machine life. Our made forming machines are allowed using more 15 years.
5.Main Machine Body
Machine frame made from H350 type steel by welding,planned on surface to guarantee precision.
All the screw bolts with grade 8.8(Some other factories use low grade4.8) to ensure fix the machine structure tightly and long life during the machine long time running. Side wall thickness: 40mm.
6. Automatic Cutting System
1) Adopts post cutting, Stop to cut;
2) The cutting blade material is Cr12 with quenched treatment.
3) Adopts welded frame for good rigidity.
4) Cutting frame has been heat treatment to avoid final product deformation. Cutting length tolerance is ±1.5mm.
5) The power of cutting is provided by hydraulic station.
6) The final product can be cut as per set length in PLC controller, and the length is automatically measured by encoder. When final product reaches the set length, machine will stop to cut the product automatically. Finish this action, machine will run again continuously.
7. Automatic PLC Control System
Control The Quantity And Cutting Length Automatically
Input the production data(such as production quantity, Length,etc.)on the touch screen, machine can finish the set production plan automatically.
A one-time buyer can set 20 batches of data in the programme.
