Explore our wholesale portfolio of CNC press brakes, plate bevelers, pipe preparation systems, and high-precision sheet metal processing equipment manufactured to rigorous ISO 9001 and CE standards.
As a premiere China wholesale press brake manufacturer and supplier, our engineering ethos combines over three decades of mechanical innovation with state-of-the-art CNC precision. We serve sheet metal fabricators, automotive OEM suppliers, aerospace contractors, and structural steel producers in over 80 countries.
Unlike standard assembly traders, our integrated manufacturing plant performs full Finite Element Analysis (FEA) on every press brake frame structure. This guarantees maximum rigidity, minimal deflection under full tonnage load, and permanent structural alignment for decades of heavy-duty operation.
Our OEM/ODM manufacturing framework delivers significant operational efficiencies, lower total cost of ownership (TCO), and unmatched bending repeatability.
Utilising dual proportional valve technology and optical linear encoders (Y1, Y2), our press brakes deliver closed-loop ram positioning accuracy within ±0.01mm, ensuring flawless bend angles across the entire worktable length.
Our eco-friendly hybrid hydraulic systems operate on-demand using main servo motors. Reduce electricity consumption by up to 60%, lower hydraulic oil temperatures, and extend component operational lifespan significantly.
Eliminate mid-length "canoe effect" angle deviations. Dynamic mechanical crowning driven by the CNC controller automatically compensates for bed deflection based on material thickness, tensile strength, and bending length.
Standardized with Delem DA-66T / DA-69T touchscreen CNC systems. Provides automatic collision detection, 3D bend sequence visualization, offline CAD/CAM programming, and direct Industry 4.0 ERP integration.
Compatible with European/Promecam, Wila, and Trumpf style tooling systems. Quick-action manual or hydraulic punch clamping cuts tool changeover times by over 70%, boosting operational efficiency.
Integrated with Lazer Safe Iris or DSP optical laser guards compliant with CE Category 4 safety standards. Protects press brake operators while enabling maximum ram speed switching down to 0mm above the plate.
Understand the shift toward smart automation, high-speed servo-electric drives, and data-driven metal fabrication.
The global metal fabrication landscape is experiencing a paradigm shift. Buyers moving beyond conventional hydraulic bending machines are prioritizing smart automation, energy conservation, and operational transparency. As a leading China wholesale press brake supplier, we stay at the forefront of this industrial transition by embedding key technology trends into our machinery architecture.
Traditional hydraulic press brakes utilize continuous-running AC motors driving gear pumps, consuming energy even while idling. Modern wholesale procurement heavily favors Electro-Hydraulic Servo Hybrid Systems and All-Electric Servo Press Brakes. Hybrid technology utilizes dual servo-driven pumps that only activate when the ram moves downward or pressurizes the workpiece. This delivers three distinct commercial benefits:
Labor shortages in skilled press brake operating personnel have accelerated demand for integrated Robotic Bending Cells. Our automated cells combine heavy-duty CNC press brakes with 6-axis industrial robots (KUKA, FANUC, or Yaskawa), automated sheet loading feeders, magnetic sheet separators, and automatic laser angle correction sensors. These systems allow continuous 24/7 "lights-out" bending production with repeatable component precision across thousands of units.
Material thickness variations, grain direction changes, and yield strength fluctuations in carbon steel or stainless steel typically cause springback angle variations. Modern CNC press brakes feature dynamic Laser Angle Measurement Systems. Non-contact optical lasers measure the live bend angle during deformation, feeding instantaneous correction data back to the CNC controller within milliseconds to guarantee precise 90° or custom angle bends on the very first hit, eliminating scrap parts.

We provide full structural transparency for machinery dealers, regional distributors, and OEM buyers seeking customized machine branding, custom color paint finishings, specialized controllers, and bespoke tooling setups.
Every frame is annealed inside gas-fired heat-treatment furnaces to eliminate internal stresses induced during heavy plate welding. Machining of the ram guides, cylinder seats, and bed beam is executed on oversized floor-type CNC boring machines in a climate-controlled hall.
Detailed technical answers for global machinery importers, procurement heads, and workshop managers.
Press brake bending tonnage depends primarily on four factors: material tensile strength ($R_m$), sheet thickness ($t$), bending length ($L$), and the V-die opening width ($V$). The standard formula for air bending mild steel (tensile strength ~450 N/mm²) is:
P (Tons) = [ 650 × t² × L ] / V
For example, bending 3mm carbon steel over a standard 24mm V-die across a length of 3000mm requires approximately 73 Tons of press force. If bending stainless steel (tensile strength ~700 N/mm²), you must increase the calculated tonnage by roughly 50%. Our engineering team provides complimentary bending force calculations and tooling simulations prior to confirming your order.
A torsion bar press brake uses a mechanical steel shaft connecting the left and right cylinders to force mechanical synchronization. It relies on internal mechanical depth stops inside the cylinders for Y-axis positioning, making offset loading difficult and limiting ram accuracy to ±0.05mm.
An Electro-Hydraulic Servo Press Brake (WE67K / System Series) utilizes dual independent proportional hydraulic valves and high-precision linear glass scales mounted on C-frames (Y1, Y2). The CNC controller monitors and adjusts each cylinder independently 500 times per second. This guarantees perfect ram parallelism even during severe off-center bending, achieving repeat positioning precision of ±0.01mm.
Hydraulic crowning uses small hydraulic cylinders embedded inside the lower bed beam that flex the table upward under pressure. However, hydraulic crowning is subject to oil temperature shifts and seal degradation over time.
Mechanical Crowning utilizes a series of continuous, high-precision reverse-curve wedges driven by an independent electric motor connected directly to the CNC controller. The controller calculates exact bed deflection using algorithms based on material thickness, length, and die selection, driving the wedges to exact micro-millimeter positions. Mechanical crowning delivers linear, repeatable, temperature-independent compensation across the full bed length.
We offer full OEM flexibility and standard integration with market-leading CNC systems:
All controllers are configured with multi-language support (English, Spanish, German, French, Russian, Portuguese, Arabic) and include offline CAD/CAM programming software licences for your engineering department.
Equipment protection during transit is paramount. Machines are sprayed with heavy-duty anti-rust oil, wrapped in thick multi-layer vacuum plastic film, and mounted on reinforced steel shipping skids. Standard height press brakes up to 200T are typically engineered to fit inside standard 40-foot High Cube (40HQ) containers with demounted top cylinders or lowered rams. Larger tonnage or long-bed machines (6-meter+) are shipped via Open Top (OT) containers or Flat Rack skids with heavy-duty waterproof tarpaulins and steel wire rigging cables.
We provide a comprehensive 2-Year Full Machine Warranty and a 5-Year Structural Frame Warranty. Major electrical components (Schneider), hydraulic valves (Bosch-Rexroth), and CNC units (Delem) carry global worldwide warranty networks. In addition, our factory remote-diagnostics modules allow our software technicians to connect directly to your machine's CNC via Internet telematics to troubleshoot alarm codes, recalibrate axis offsets, and update system software instantly.
Whether you require a single high-precision CNC press brake, an automated robotic bending cell, or full OEM distributor manufacturing partnerships, our engineering team delivers factory-direct pricing, custom specs, and technical support.
