Dayyani machinery for cutting, bending, punching, rolling, and straightening sheet metal
The core Dayyani catalog includes press brakes, hydraulic guillotine shears, electromechanical shears, hydraulic PLC bending machines, single punching machines, multipurpose punching machines, sheet rolling machines, and straightening machines. Each machine family addresses a specific part of the metal fabrication workflow, from cutting and bending to punching, forming, rolling, and sheet preparation.
Hydraulic BendingFull Hydraulic Bending Machine with PLC
The process of bending metal sheets is one of the most commonly used manufacturing processes. Dayyani full hydraulic bending machine with PLC control features robust structure, unique design, high power and precision in bending operations.
Electromechanical ShearElectromechanical Guillotine Shears
One of the initial processes in metal-based manufacturing is the cutting process. Manufacturers must cut materials to appropriate dimensions quickly, with quality, and with minimal waste. Dayyani electromechanical guillotine shears are the ideal tool.
Hydraulic GuillotineHydraulic Guillotine Shear
To convert metals, primarily steel and iron, into pieces and products, we require cutting operations. The cutting process, especially cutting sheets, is crucial for minimizing waste and maximizing speed. Dayyani hydraulic guillotine shears are the optimal choice.
Press BrakePress Brake
The Press Brake, an industrial metalworking machine, employs specialized tooling (punch and die) to bend metal sheets with precision and repeatability. Dayyani manufactures press brakes ranging from 30 to 400 tons with various configurations.
Sheet RollingSheet Rolling Machine (3 & 4 Roller)
The sheet metal rolling machine is used for rolling sheets into full circles, half circles, cones and more. Manufactured by Dayyani in 3 and 4 roller configurations, available in 1 to 4 meter widths with 2-50mm thickness capacity.
Straightening MachineStraightening Machine (Sheet Leveler)
Steel sheet manufacturers produce a significant portion of their output in coil (roll) form for ease of transport. The sheet straightening line by Dayyani provides the highest quality and efficiency, converting coils to flat sheets at desired lengths.
Punch MachineMulti-Purpose Punch Machine (8-in-1)
The multi-purpose punch machine by Dayyani features 30mm sheet punching capacity, 25 HP motor, and 8 functions: punching, sheet cutting, angle cutting, channel cutting, rebar cutting, square bar cutting, U-bending, and beam cutting.
Punch MachineSingle Punch Machine — Hydraulic PLC (HP3030)
Thanks to technological advancements, production processes have become more efficient. The single punch hydraulic PLC machine model HP3030 by Dayyani delivers precision and reliability.
Engineering and manufacturing capability
Industrial machinery built on practical experience, engineering calculation, and production-line needs
Dayyani is not positioned as a generic machinery seller. Its public identity is built around design, manufacturing, and lifecycle support for industrial equipment. Machine structure, material selection, component quality, operating precision, ease of maintenance, and durability under heavy workshop conditions are treated as core requirements.
Factory development
Dayyani started operations in 1974 with electrically powered machines in a compact workshop and expanded as product quality and demand increased.
Later growth brought larger production spaces, additional shear-product lines, and expanded machining capability.
The public positioning remains rooted in production capability, machine design, and long-term support after delivery.
Design and fabrication
Dayyani emphasizes in-house design and production.
Machining capability
The historical narrative ties growth to heavier production and CNC machining tools.
After-sales service
Service continuity, documentation, and operator support remain part of the public promise.
Services
From spare parts and installation to repair, overhaul, punches, dies, and hydraulic components
Dayyani services include spare-part supply and replacement, installation and commissioning, after-sales support, mechanical, hydraulic, and electronic repairs, major overhaul, and production of punches, dies, and hydraulic components. These services are intended to support customers after purchase and keep machines productive over time.
