900 & 840 Double Layer Trapezoidal Roofing Sheet Roll Forming Machine

Manufacturer: Hebei Xinnuo Roll Forming Machinery Co., Ltd. | Core Keyword: Double Layer Roll Forming Machine Factory

As a professional Double Layer Roll Forming Machine Factory, Hebei Xinnuo Roll Forming Machinery Co., Ltd. specializes in manufacturing dual-profile metal roofing equipment, among which the 900+840 double layer trapezoidal roll former is one of our star-selling products. Double Layer Trapezoidal Roofing Sheet Roll Forming Machine is designed for efficient metal roofing production. It combines two trapezoidal roof panel profiles in one machine with PLC automatic control, high precision rollers, hydraulic cutting system and customized solutions for global roofing manufacturers. This dual-purpose equipment perfectly solves the problem of simultaneous production of two mainstream trapezoidal roof panels, greatly optimizing factory layout and lowering comprehensive investment costs.

The machine is equipped with an independent double-layer feeding platform, separating raw material feeding paths for 900 and 840 trapezoidal sheets respectively. The frame is welded with thickened steel plates, bearing heavy loads of color steel coils, galvanized coils and aluminum coils with thickness ranging from 0.3mm to 0.9mm. Adjustable left-right limit baffles effectively correct material deviation during high-speed feeding, reducing material waste and improving continuous production efficiency without frequent manual adjustment.

All forming rollers are forged from high-quality GCr15 bearing steel, processed by integral quenching and mirror polishing, with surface hardness reaching HRC58-62. The rollers maintain stable forming precision for long-term operation, ensuring neat wave arcs and no rebound deformation of finished trapezoidal sheets. Two groups of independent roller rows are arranged vertically, supporting free switching between 900 and 840 production modes without disassembly and replacement of molds, saving production preparation time for customers.

High-strength industrial transmission chains are adopted for power transmission between each roller station, with strong tensile resistance and stable power output. The chain drive structure reduces vibration during high-speed operation, making the whole machine run smoothly and quietly. Regular lubrication maintenance can extend the service life of the chain transmission system, lowering long-term equipment maintenance costs for metal roofing processing factories.

The integrated machine body adopts overall stress relief welding technology to avoid frame deformation after long-time heavy load operation. The built-in hydraulic cutting system realizes fixed-length automatic cutting for both upper and lower layers, with alloy steel cutting blades that produce burr-free finished panels. The touch screen PLC control cabinet realizes one-click mode switching, automatic length counting, speed regulation and fault alarm, lowering the operation threshold for factory workers.

Hebei Xinnuo, a reliable Double Layer Roll Forming Machine Factory, provides customized service including adjustable forming width, special working voltage and customized mold patterns to match construction standards of Southeast Asia, Africa, Latin America and Europe.
