Key Features
APK Heavy Features
Standard features that set this machine apart in demanding manufacturing environments.
Precision & Performance
- Three rolls independently driven by separate hydraulic motors — two bottom rolls move independently for slip-free 3-roll bending
- Infinitely variable speed of rotation for precise control across different material grades and section sizes
- Hardened and ground special-steel shafts with heavy-duty bearings for consistent accuracy under high forming loads
- Separate moveable control panel with Siemens HMI for convenient operator positioning
Cutting Capability
- Side supporters move in three directions to reduce deformation and facilitate pre-bending on both edges
- Handles the full range of structural profiles — angles, T-sections, channels, beams, flat bar, rounds, tubes, and square sections
Built-In Extras
- St-52 welded steel construction body with enlarged roll diameters for minimum flexion and reduced material deformation
- Hydraulically adjustable guide rolls keep workpieces aligned through the forming zone on all models
- Lower rolls hydraulically moveable up and down with digital position display for repeatable setups
- Spiral bending capability and ring rolling for architectural and industrial curved-section applications

hydraulic/mechanical profile bending machine
APK Medium
The Akyapak APK Medium Series brings professional-grade profile bending capability to shops that need versatility without the footprint of a heavy-duty machine. Six models range from the compact APK 61 at 5.4 HP to the APK 240 at 40 HP, handling angles, T-sections, flat bar, square bar, rounds, tubes, and channels across a broad capacity range. All models feature a St-52 steel construction body, hardened and ground 42CrMo4 special-steel shafts, hydraulically moveable lower rolls, digital position display, and both horizontal and vertical working orientations. Rolls are driven by a hydraulic motor through a planetary gearbox for smooth, controllable forming. ACM supplies every APK Medium model from Ontario with tooling packages, installation, and dedicated after-sales support.
CNC/NC tube and pipe bending machine
ABM
The Akyapak ABM Series covers the full spectrum of tube and pipe bending — from the all-electric ABM E-25 multi-stack bender to the heavy-duty ABM 76 CNC 3 with three-die servo control. These machines bend mild steel, stainless steel, aluminium, and similar materials into simple or complex shapes with repeatable accuracy across both high-volume production and single-piece work. CNC models feature servo-controlled bending, feeding, shifting, and turning axes, a 15-inch colour touchscreen with 3D bend preview, YBC programming mode, and automatic tube length calculation. NC models provide a cost-effective semi-automatic option for shops with moderate throughput requirements. The ABM range serves automotive, furniture, HVAC, insulation, and general fabrication applications where bend quality and repeatability are critical. ACM provides the full ABM range from Cambridge, Ontario with die packages, mandrel tooling, installation, and training.
hydraulic dishing press
BMB-P
The Akyapak BMB-P is purpose-built for forming dished heads — the concave end caps used in pressure vessels, storage tanks, boilers, and process equipment. Available in capacities from 150 to 1,600 metric tons with working diameters from 20 inches to 33 feet, the BMB-P uses oversized heat-treated dies and a stress-relieved high-alloy steel frame to deliver consistent dish profiles with minimal springback. Models above 250 metric tons incorporate pre-stressed tie-rods and side shoulders for added rigidity under extreme forming loads. The main control screen is designed around a user-friendly interface that reduces learning time — operators achieve accurate, repeatable results without years of specialised dishing experience. Cylinder bodies, piston groups, and critical hydraulic components are heat-treated and chromium-plated for long service life under continuous production duty. ACM supplies BMB-P dishing presses from Ontario with application engineering, die selection guidance, and full lifecycle support.
