China remains one of the most practical sourcing markets for CNC press brake bending equipment because it combines large-scale machine-tool production, specialized industrial clusters, broad component availability, and export-oriented manufacturing. For professional buyers, however, the right partner is not necessarily the supplier with the lowest quoted machine price—it is the manufacturer that can prove frame accuracy, hydraulic or servo-system reliability, controller integration, safety compliance, tooling compatibility, commissioning support, and spare-parts continuity.
This guide evaluates ten China-based or China-serving suppliers from a procurement perspective. It is designed for sheet-metal fabricators, OEMs, distributors, and project managers seeking long-term press brake bending partners rather than one-off online quotations.
Buyer note: This is an editorial supplier-selection guide, not a certification, audit, or legal approval. Machine specifications, certifications, lead times, production capacity, export scope, and service terms must be verified directly with each supplier before placing an order.
An experienced procurement team should assess more than tonnage, bed length, and price. Press brake performance depends on how well the entire system is engineered, assembled, tested, documented, and supported after delivery.
We screened suppliers using the following dimensions:
| Evaluation Area | What Buyers Should Check | Why It Matters |
|---|---|---|
| Factory authenticity | Business licence, factory address, live factory audit, equipment list, serial-number traceability | Distinguishes real manufacturers from trading companies |
| Engineering capability | Frame design, stress relief, CNC crowning, backgauge axes, hydraulic or electric-servo configuration | Determines repeatability, deflection control, and bending accuracy |
| Quality control | Incoming steel inspection, welding process, machining tolerances, assembly testing, final acceptance records | Reduces risk of poor alignment, leakage, vibration, or unstable accuracy |
| Controller and components | Delem, ESA, Cybelec, Estun, Siemens, Bosch Rexroth, Hoerbiger, or equivalent component documentation | Affects programming, maintainability, local servicing, and spare-parts availability |
| Safety and compliance | CE Declaration of Conformity, risk assessment, electrical documentation, guarding, emergency-stop system, applicable standards | Essential for EU and other regulated markets |
| Customisation support | OEM branding, special daylight, throat depth, tandem linkage, tooling layout, automation integration | Important for distributors, specialized fabricators, and project buyers |
| Delivery reliability | Production schedule, pre-shipment test, FAT videos, packaging plan, spare-parts kit, export documentation | Prevents costly commissioning delays |
| After-sales capability | Remote diagnostics, English manuals, training, service-response process, spare-part stock | Determines real machine uptime after installation |
A reliable CNC press brake is not defined only by whether it can bend a test coupon. Buyers should investigate the machine's ability to maintain accuracy over repeated cycles and across changing materials.
Key technical indicators include:
- Nominal bending force: Usually expressed in tons or kilonewtons; it must be calculated against material tensile strength, thickness, bend length, die opening, and bending method.
- Working length: The usable bending length must match the buyer's largest workpiece and tooling setup.
- Y-axis synchronisation: Electro-hydraulic CNC machines typically use independent cylinders and linear encoders to control ram parallelism and repeatability.
- Backgauge configuration: X, R, Z1, Z2, X5, and X6 axes affect part positioning, complex-bend capability, and throughput.
- Crowning system: CNC crowning compensates for bed and ram deflection on long bends, helping maintain a more consistent angle across the workpiece.
- Frame rigidity and stress relief: The welded frame should be designed, machined, and processed to manage deformation. Ask how the supplier controls residual stress after welding.
- Hydraulic system quality: Valve blocks, seals, piping, filtration, oil temperature, and leak testing are practical indicators of durability.
- Tooling compatibility: Confirm the tool clamping standard, punch and die style, segmentation, and availability of custom tools.
- Safety system: For CE-market machines, buyers should examine guarding, laser safety devices where applicable, two-hand controls, emergency circuits, electrical documentation, and risk assessment.
CE is not a product decoration. A credible CE-marked press brake should be supported by a Declaration of Conformity, technical file, applicable standards, safety instructions, electrical schematics, and traceable machine identification. RoHS is generally more relevant to electrical and electronic equipment components than to the core mechanical qualification of a press brake; it should not be used as a substitute for machine-safety compliance.
China is a leading global machine-tool producer and exporter. Industry analysis reports that China accounted for approximately one-third of global metalworking-machine-tool production in 2024, while its machine-tool export value more than doubled between 2015 and 2024. It also reportedly surpassed Germany as the largest machine-tool exporter in the first half of 2025.
For press brake buyers, China's advantage is not simply lower labour cost. It is the presence of interconnected manufacturing ecosystems:
- Ma'anshan, Anhui: A concentrated cluster for press brakes, shearing machines, bending tooling, hydraulic equipment, and sheet-metal machine components.
- Yangzhou and Jiangsu: A major base for CNC machine tools, automated sheet-metal systems, laser cutting, stamping, and industrial automation.
- Wuxi and the Yangtze River Delta: A strong industrial region for heavy machinery, fabrication equipment, automation, and precision manufacturing.
- Jinan and Shandong: A prominent manufacturing area for fiber-laser equipment and integrated sheet-metal processing systems.
The Ma'anshan cluster is especially relevant for press brake sourcing. Local manufacturers, tooling suppliers, hydraulic-component vendors, and metalworking subcontractors operate within a short logistics radius. This can shorten iteration cycles for special tooling, custom backgauge layouts, machine configurations, and replacement parts.
The following list combines suppliers requested for this guide with established press-brake manufacturers and related machining partners. The ranking reflects the editorial structure requested, not an independent numerical performance score. Buyers should evaluate each candidate against their specific tonnage, material, automation, compliance, and after-sales requirements.

Best Fit: Buyers sourcing press brake components, fixtures, tooling parts, backgauge components, or related precision-machined assemblies
Anebon Metal is not positioned primarily as a complete CNC press brake manufacturer. It is included because professional press-brake procurement often involves a wider supply chain: precision-machined components, special fixtures, brackets, machine enclosures, custom mechanical assemblies, and replacement parts.
Anebon states that it was founded in 2010, focuses on design, production, and sales in the hardware industry, and holds ISO 9001:2015 certification. It also describes CNC milling, turning, grinding, and wire-EDM capabilities, along with precision-part tolerance support up to ±0.002 mm.
For manufacturers, distributors, and engineering teams developing press-brake systems or aftermarket parts, Anebon may be useful as a component-level OEM machining partner. This is particularly relevant for low- to medium-volume machined parts where a complete machine builder may not have the most economical in-house process.
Core advantage: Precision custom machining capability and ISO 9001:2015 quality-system claim, with broad process coverage.
Buyer caution: Confirm whether the stated tolerance is achievable for the specific material, geometry, batch size, measurement method, and production process. A tight tolerance stated on a website should be translated into a drawing-level inspection plan and written acceptance criteria.
Established: Verify directly with supplier
Location: China
Main Markets: Global product developers, OEMs, and prototype buyers
Core Scope: Rapid prototyping, CNC machining, sheet-metal fabrication, 3D printing, and rapid tooling
OEM/ODM Strength: Prototype validation, low-volume production, engineering-feedback support
Best Fit: Buyers needing prototype sheet-metal parts, machine guards, enclosures, test fixtures, or pre-production fabrication before committing to production tooling
SC Rapid Manufacturing is not a full press-brake equipment manufacturer. Its relevance lies in the pre-production ecosystem around press brake bending projects. The company describes a workflow that uses 3D printing, CNC machining, sheet metal, and rapid tooling to convert CAD concepts into prototypes and pre-production parts for design validation and functional testing.
For a press-brake distributor, industrial-equipment developer, or OEM, this kind of supplier can support early machine-development stages. Examples include:
- Prototype control enclosures
- Safety guarding panels
- Sheet-metal covers
- Custom workpiece-support fixtures
- Machine-interface brackets
- Operator-panel components
- Trial parts used to validate bending-process capability
Core advantage: Rapid iteration between CAD design, prototype production, functional testing, and lower-volume production.
Buyer caution: Prototype-shop capability does not automatically demonstrate qualification for complete machine manufacturing or safety-critical structural fabrication. Separate supplier assessments are required for prototype parts, structural frames, hydraulic assemblies, and finished press brakes.
Established: Verify directly with supplier
Location: China
Main Markets: Global CNC-machining and custom-part customers
Core Scope: Custom CNC machining and CAD-file-based project review
OEM/ODM Strength: Design-for-manufacturing review, custom mechanical components, prototype and production parts
Best Fit: Buyers requiring custom machined parts for press brake machines, automation cells, sheet-metal fabrication fixtures, or maintenance inventories
Flycncpart describes an online CAD and 3D-file submission process followed by a design review intended to identify potential manufacturing issues or improvements before production begins.
This can be valuable for buyers who need machining support around a press-brake installation, including custom tooling holders, gauging fixtures, robot-end-of-arm interfaces, feeder parts, material-handling brackets, or maintenance components.
Core advantage: CAD-driven project intake and early DFM review.
Buyer caution: Before awarding a production order, request details about machine capacity, materials, achievable tolerances, inspection equipment, quality records, surface-treatment management, traceability, and sample-approval procedure.
Established: 1956
Location: Yangzhou, Jiangsu, China
Main Markets: Domestic and international sheet-metal manufacturing, automation, and industrial-equipment customers
Core Products: CNC press brakes, panel benders, turret punches, laser cutting systems, stamping equipment, and automated processing lines
OEM/ODM Strength: Automated bending cells, integrated sheet-metal processing, project-engineering support
Best Fit: Medium-to-large fabricators seeking automation, multi-process integration, and structured industrial capability
Yawei is one of China's established machine-tool manufacturers. Public information identifies its product portfolio as including CNC bending machines, panel benders, turret punches, laser-cutting systems, stamping equipment, and automated flexible sheet-metal processing systems.
For buyers needing more than a standalone hydraulic press brake, Yawei is a candidate for integrated production concepts such as automated bending cells, laser-to-bend workflows, and higher-throughput sheet-metal operations.
Core advantage: Broad product range and automation orientation, supported by a long industrial history.
Buyer caution: Large manufacturers may have more standardized commercial processes, so clarify how much customization is available, the project handover method, export commissioning support, and the required lead time for special configurations.
Established: Verify the exact legal entity and current corporate structure directly
Location: China
Main Markets: International fabricators and industrial-equipment users
Core Products: CNC bending machines, shearing machines, laser cutting systems, and sheet-metal equipment
OEM/ODM Strength: Integrated metal-fabrication equipment and export project support
Best Fit: Buyers seeking a recognized CNC sheet-metal equipment brand with a broad export profile
JFY International is frequently identified in industry listings as a supplier of CNC bending and shearing equipment and as part of China's broader sheet-metal machinery landscape.
The company is relevant for procurement teams evaluating established brands with experience in CNC sheet-metal machinery. Its suitability should be assessed based on the precise press brake series, controller option, local service arrangement, tooling standard, and automation requirements.
Core advantage: Broad exposure to sheet-metal fabrication equipment and export-oriented machine supply.
Buyer caution: Confirm the exact contracting entity, manufacturing location, machine-series specification, warranty responsibility, and local after-sales plan. A brand name alone does not define the support structure for a specific region.
Established: Verify direct corporate and site information before contracting
Location: Ma'anshan, Anhui, China
Main Markets: Global sheet-metal fabrication and industrial manufacturing
Core Products: Hydraulic CNC press brakes, hybrid servo press brakes, electric servo press brakes, shearing machines, and fabrication equipment
OEM/ODM Strength: Customized press-brake configurations, automation integration, export machine supply
Best Fit: Buyers seeking a China-based press-brake specialist with attention to energy-efficient bending technology
ACCURL describes its portfolio as including green hybrid-servo and electric-servo bending technology alongside CNC press brake systems. Its Ma'anshan location also places it inside the Anhui press-brake and tooling cluster.
Hybrid and electric-servo designs can be attractive where buyers aim to reduce hydraulic-oil dependence, power consumption, noise, or maintenance needs. However, the actual benefit depends on duty cycle, material range, machine size, part geometry, and local service access.
Core advantage: Focus on CNC press brakes and energy-conscious bending technologies.
Buyer caution: Ask for measurable specifications—not just "energy-saving" claims. Request installed power, typical operating consumption, ram speed under load, noise data, hydraulic-oil requirements, maintenance schedule, and comparable test conditions.
Founded: 1998
Location: China
Main Markets: International metal-fabrication customers
Core Products: CNC press brakes, shearing machines, laser cutting systems, and fabrication machinery
OEM/ODM Strength: Customized machine configurations, distributor cooperation, export-oriented product supply
Best Fit: Buyers seeking a long-running supplier with a broad portfolio of sheet-metal fabrication equipment
KRRASS is identified in industry roundups as a manufacturer established in 1998 that specializes in CNC press brakes, shearing machines, and laser-cutting equipment.
The company may be relevant to buyers seeking a supplier with a broad line of fabrication machines and potential one-stop purchasing across bending, shearing, and cutting.
Core advantage: Product-range breadth and an established position in China's sheet-metal machine sector.
Buyer caution: Compare the exact configuration, not brand-level claims. A 100-ton hydraulic press brake with a basic NC controller is not comparable to a multi-axis electro-hydraulic CNC model with CNC crowning and automated tool clamping.
Established: Verify current company information directly
Location: Wuxi, Jiangsu, China
Main Markets: Heavy fabrication, industrial manufacturing, and international equipment buyers
Core Products: CNC press brakes, shears, laser cutting systems, and larger sheet-metal fabrication equipment
OEM/ODM Strength: Heavy-duty configurations, special machine dimensions, integrated fabrication lines
Best Fit: Buyers handling thicker plate, longer bend lengths, or larger industrial fabrication projects
Wuxi Shenchong is commonly cited in China press-brake manufacturer lists and is associated with CNC press brakes and wider metal-forming equipment.
For heavy-fabrication projects, the important supplier-evaluation topics change. Buyers should focus on frame rigidity, bed-length straightness, cylinder synchronisation, crowning strategy, transport method, foundation requirements, installation support, and load conditions.
Core advantage: Potential fit for larger-scale and heavy-duty fabrication applications.
Buyer caution: Require a documented tonnage calculation against your actual material grade, thickness, die opening, bend length, and bending method. Do not select a machine based on nominal tonnage alone.
Established: Verify directly with supplier
Location: China
Main Markets: Global metal-fabrication and industrial-equipment buyers
Core Products: CNC hydraulic press brakes, electric press brakes, shearing machines, laser equipment, and automation solutions
OEM/ODM Strength: Customized equipment configurations and export machine projects
Best Fit: Buyers comparing conventional hydraulic and full-electric press-brake options
ADH Machine Tool is widely referenced in industry lists as a Chinese manufacturer of CNC metal-forming equipment, including CNC bending machines, hydraulic press brakes, and full-electric press brakes.
For buyers deciding between hydraulic, hybrid, and full-electric press brakes, ADH can be a useful comparison candidate. Full-electric designs can offer advantages in certain precision, energy, and maintenance contexts, while hydraulic machines remain common for broader tonnage ranges and heavy-duty applications.
Core advantage: Product coverage across different press-brake drive technologies.
Buyer caution: Compare the machine's real bending capability, not only its drive label. Ask about duty cycle, tooling compatibility, ram-repeatability test criteria, maximum open height, usable stroke, throat depth, controller support, and locally available spare parts.
Published company websites and third-party sources do not provide standardized, independently verified annual press-brake capacity, MOQ, or certification scope for all companies. The table therefore identifies the commercial profile buyers should verify, rather than presenting unverified numbers as facts.

A request such as "Need a 100-ton press brake" is incomplete. A professional RFQ should include:
- Material type and tensile strength
- Maximum thickness and bend length
- Minimum flange size
- Typical and maximum workpiece dimensions
- Required bend-angle tolerance
- Annual production volume and shift pattern
- Air bending, bottoming, or coining requirement
- Desired controller brand
- Backgauge axes required
- Crowning requirement
- Tooling standard and preferred clamping system
- CE or destination-market compliance requirements
- Automation, robot, conveyor, or loading requirement
- Power supply standard
- Destination port or delivery address
- Required delivery date
Ask for evidence that the supplier is a genuine machine manufacturer:
1. Live video tour of the workshop, machining area, assembly line, test bay, and finished-machine stock.
2. Business registration documents matching the contract entity and bank account.
3. Serial-number records and examples of export packing.
4. Photos or videos of the exact proposed model under test.
5. A list of key bought-in components and brand options.
6. Quality-control records for frame machining, cylinder alignment, and final testing.
7. Contactable references where appropriate and permitted.
A factory acceptance test should use representative material, thickness, length, tooling, and bend geometry—not a thin, short test strip that hides deflection and angle inconsistency.
Include the following in the FAT agreement:
- Material grade and actual thickness
- Bend length
- Die opening
- Punch radius
- Target angle and allowable tolerance
- Number of repeated bends
- Backgauge positioning test
- Crowning demonstration across the working length
- Hydraulic leak and pressure checks
- Safety-device test
- Video records and signed inspection report
- Final machine photos and serial number before shipment
The machine quote can be only part of the project cost. Budget separately for:
- Punches and dies
- Segmented tooling
- Tool clamps and adapters
- CNC crowning
- Safety laser devices
- Operator training
- Installation and commissioning
- Electrical adaptation
- Freight, marine insurance, duty, and inland transport
- Spare parts
- Local technician support
- Future tooling and controller upgrades
A press brake is high-value, heavy, and sensitive to shipping damage. Confirm:
- FOB, CIF, DAP, or DDP responsibilities
- Container type and loading plan
- Corrosion protection for sea transport
- Wooden-crate or steel-frame packaging requirements
- Hydraulic-oil handling and leakage prevention
- Separate packing for controller, tooling, and fragile components
- Serial-number marking on packing list
- Bill of lading, commercial invoice, packing list, certificate of origin, CE documents, and manuals
- Insurance terms and damage-claim process
A commonly referenced HS code for CNC press brakes is 8462.21, but buyers should confirm tariff classification with their customs broker because machine type, control system, country of import, and trade rules can affect duty treatment.
Two machines described as "100 ton × 3200 mm" may differ substantially in frame weight, cylinder system, encoder quality, CNC axes, crowning, controller, tooling, safety components, and assembly quality.
Avoid it: Request a full technical specification and component list line by line.
A generic document may not apply to the exact machine model, electrical configuration, safety system, or destination market.
Avoid it: Request the model-specific Declaration of Conformity, applicable standards, electrical drawings, safety manual, and traceable serial-number information.
Mild steel, stainless steel, aluminium, and high-strength steel require different bending-force calculations. A machine selected for mild steel may be undersized for the same thickness of high-tensile material.
Avoid it: Submit the actual material grade and tensile-strength range with your RFQ.
A press brake without correctly matched tooling can become an expensive idle asset. Special bends, hems, boxes, deep channels, and short flanges often need non-standard punches, dies, or clamping solutions.
Avoid it: Send part drawings and ask the supplier to provide a tooling proposal, simulation, and sample-bend plan.
Some suppliers use OEM to mean logo printing rather than true mechanical or control-system customization.
Avoid it: Specify exactly what must be customized: paint colour, logo, controller interface, electrical standard, machine dimensions, tooling, guarding, automation interface, manuals, and spare-parts packaging.
An industry reality that is often missed in online supplier comparisons is that a visually heavy welded frame does not guarantee long-bend accuracy. On a long workpiece, ram and bed deflection can cause the bend angle to open in the centre or vary along the length.
The most practical proof is a documented crowning and full-length bending test using material close to your real production requirement.
Ask the supplier to perform:
1. A full-length bend with crowning disabled.
2. The same bend with CNC crowning enabled and adjusted.
3. Angle measurement at the left, centre, and right positions.
4. Repeated tests after a production-like sequence.
5. A test report that records material, die opening, punch, bend length, target angle, and results.
This is more useful than relying on machine paint quality, a large nominal tonnage figure, or a generic claim that the frame underwent stress relief.
China offers a deep and diverse supply base for press brake bending equipment, from flexible Ma'anshan-based OEM manufacturers to large automated sheet-metal system builders. The best supplier depends on your workpiece geometry, material range, output volume, automation plan, compliance needs, and long-term service expectations.
For buyers who need a customized CNC press brake or a broader sheet-metal equipment package, Maanshan Deyan Precision Machinery Technology Co., Ltd. / CNDY-Press is a practical option to evaluate. The company's stated focus on CNC press brakes, related fabrication equipment, OEM/ODM manufacturing, custom production, and after-sales support may fit distributors and small-to-medium industrial users seeking a responsive, project-based manufacturing partner.
Request a live factory video tour, legal business documents, factory address, equipment list, assembly-line footage, serial-number records, real FAT videos, and references. The bank-account name, contract entity, factory entity, and export documents should be consistent. If possible, conduct a third-party audit before paying a major deposit.
Ask for the complete certificate, including certificate number, issuing body, legal entity, factory address, scope, issue date, and expiry date. Then contact the certification body or use its public verification database where available. Ensure that the certificate covers the manufacturing site and relevant machinery scope—not a sales office or unrelated product category.
Provide material type, tensile strength, thickness, bend length, bending method, die opening, inside bend radius, and grain direction where relevant. Tonnage tables provide estimates, but the supplier should validate the calculation for the actual tooling and machine geometry.
No. Electric press brakes can offer low noise, fast response, less hydraulic maintenance, and energy advantages for certain applications. Hydraulic or hybrid-servo machines may be more suitable for high tonnage, long bending lengths, heavy duty cycles, or broader material conditions. Select based on your actual parts, throughput, operating costs, and service capability.
Include representative material, actual thickness, full or near-full bend length, approved tooling, target-angle tolerances, repeated bending, backgauge accuracy, crowning performance, hydraulic checks, safety-device verification, and a signed report tied to the machine serial number.
