RAYMAX Plate Rolling Machine – Digital Roll Position Display & Asymmetric Three-Roll Design

RAYMAX plate rolling machine uses an asymmetric three-roll design where the top roll is offset relative to the two bottom rolls, enabling easier plate feeding and removal of cylindrical workpieces. Digital displays show real-time roll position and bending angle, allowing operators to replicate past jobs with ±0.5mm accuracy. The hydraulic motor drives all three rolls simultaneously for uniform torque distribution, reducing slip on heavy plates. Maximum width 3000mm, thickness 25mm for carbon steel. Typical applications include small pressure vessels, chimney stacks, and irrigation pipe. RAYMAX offers a roll bending calculator software that generates rolling parameters from input diameter, material, and thickness, reducing trial and error.

Economical Three-Roller Design for General Sheet Shaping

RAYMAX plate rolling machine offers the W11 mechanical three-roller plate rolling machine, mainly used for rounding off plates from 4mm to 40mm thickness and 1500mm to 4000mm in length. It is a very affordable and economical plate rolling machine, the best choice for general fabrication shops and maintenance departments. The three-roller initial pinch type handles plates with hydraulic or mechanical force to shape flat sheets into accurate cylinders, achieving straightness deviations below 0.5mm per meter. RAYMAX plate rolling machine is ideal for pressure vessels, pipelines, storage tanks, boilers, wind power towers, and tunnel arches. The hardened steel rolls (HRC 52-55) resist wear when rolling carbon steel, stainless steel, and aluminum. RAYMAX provides a digital bending calculator to generate rolling parameters from customer drawings, reducing setup time by 50%.

Four-Roller Hydraulic Model for Pre-Bending Without Flat Ends

RAYMAX four-roller plate rolling machine is suitable for bending work of sheet metal, capable of rolling round, arc, and tapered workpieces within a certain range. The four-roller design features a hydraulic pinch roll that grips the plate edge with adjustable pressure, preventing slippage when rolling high-strength steel plates. It has a pre-bending function at the end of the board, eliminating flat sections and reducing welding preparation time by up to 40%. This is critical for pressure vessel shells where consistent roundness is essential for butt welding. The four-roller configuration pre-bends both ends in a single pass, saving time and improving accuracy. Maximum rolling width 4000mm, thickness 60mm for mild steel. RAYMAX plate rolling machine is the preferred choice for pressure vessel fabricators, oil storage tank manufacturers, and penstock producers.

Pressure vessel manufacturing demands the highest levels of precision and quality from plate rolling machines, as cylindrical shells must maintain consistent wall thickness and roundness to withstand internal pressures while meeting strict ASME and PED certification requirements. A pressure vessel typically consists of multiple rolled cylindrical shells welded together, with diameters ranging from 500mm to over 4,000mm and plate thicknesses from 10mm to 60mm for carbon steel pressure vessels. Four-roll plate rolling machines are specifically engineered for this demanding application, delivering roundness tolerances within ±1 mm across the entire shell diameter. The elimination of flat residual edges through integrated pre-bending significantly reduces weld preparation time and improves seam quality, critical for pressure retention integrity. Typical pressure vessel applications include chemical reactors requiring stainless steel construction for corrosion resistance, steam boilers fabricated from carbon steel plates 10mm to 60mm thick, oil and gas storage tanks where weld quality directly impacts leak prevention, and air compressor tanks requiring consistent diameter for end cap fit-up. RAYMAX’s plate rolling machines are manufactured with high-grade material and go through rigid quality control to ensure they can be treated as heavy-duty machines, providing extended years of reliability. CNC control with memory storage allows fabricators to save rolling programs for repeated vessel designs, ensuring each shell matches the previous one within tight tolerances. For multi-shell vessels where sections are welded together in the field, consistent rolling from section to section is essential for proper alignment. The machine’s variable-geometry top roll and side supports enable precise control over ovality, reducing post-bending rework by up to 80%. RAYMAX’s collaboration with a renewable energy firm involved customizing a 4-roll hydraulic roller to form 10mm-thick stainless steel tubes for wind turbine towers, demonstrating the machine’s capability for precision pressure vessel and energy industry components. Our rolling machines are suited for use in the petrochemical industry among other sectors, helping to come up with different metal working solutions.

Frequently Asked Questions

What are the advantages of fiber laser welding over TIG welding?

Fiber laser welding is 4-10 times faster, produces a significantly smaller heat-affected zone (minimizing distortion), and offers better energy efficiency with lower consumable costs. The process also creates clean, spatter-free welds that often require no secondary finishing.
RAYMAX press brake machines are available with bending force capacities from 40 tons up to 2,000 tons, with working lengths ranging from 1600mm to 12,000mm, enabling them to handle everything from small precision parts to heavy plate bending.
A fiber laser cutter uses a fiber-optic-delivered laser beam (1064nm wavelength) focused into a 0.1mm spot to melt and vaporize metal materials, creating clean, accurate cuts for automotive, aviation, and shipbuilding industries.
Fiber laser welding machines can weld multiple materials including stainless steel, aluminum, copper, carbon steel, titanium alloys, and other metals, with adjustable parameters to accommodate different thicknesses and material types.
