China is a major sourcing base for bending press machines, CNC press brakes, hydraulic press brakes, servo press brakes, tandem bending systems, and sheet-metal fabrication equipment. In 2025, China's metal-processing machine-tool exports reached USD 9.68 billion, up 17.9% year on year, according to the China Machine Tool & Tool Builders' Association (CMTBA).
For professional buyers, this export growth is not a reason to choose a supplier blindly. A CNC press brake is a long-life capital asset. Its true cost is determined by frame rigidity, ram repeatability, crowning performance, hydraulic or servo reliability, controller configuration, safety system, tooling compatibility, commissioning support, spare-parts availability, and uptime after installation.
This guide is designed for procurement managers, fabricators, OEMs, contractors, and distributors seeking a long-term CNC bending press machine manufacturer in China. It covers supplier selection, technical comparison, hidden sourcing risks, quality verification, logistics, and the practical questions to ask before placing an order.
An attractive quotation does not prove that a machine will meet your bending tolerance, production volume, operator-safety requirements, or long-term maintenance expectations. A meaningful supplier evaluation should look beyond the advertised tonnage and bending length.
| Evaluation Area | What Buyers Should Verify | Why It Matters |
|---|---|---|
| Machine frame | Steel grade, welding process, stress relief, machining accuracy, frame deflection, and throat depth | Affects bending angle consistency and long-term structural stability |
| Bending performance | Nominal tonnage, working length, stroke, daylight, ram speed, backgauge accuracy, and crowning method | Determines which materials, thicknesses, tools, and parts can be processed |
| CNC control | Delem, ESA, Cybelec, or other controller configuration; axis count; offline programming support | Influences programming speed, repeatability, operator efficiency, and training needs |
| Hydraulic or servo system | Pump, valves, seals, cylinders, servo drive, energy consumption, and service access | Affects precision, operating cost, noise, and maintenance requirements |
| Safety compliance | CE Declaration of Conformity, risk assessment, guarding, laser safety device, emergency stop, electrical documentation | Essential for legal market access and operator protection |
| Manufacturing quality | Incoming material inspection, frame machining, hydraulic testing, no-load test, loaded bending test, and final inspection | Reduces commissioning problems and early failures |
| OEM/ODM flexibility | Tonnage, bed length, open height, backgauge, tooling, automation, branding, language, and electrical configuration | Critical for distributors and specialized fabrication projects |
| After-sales support | Remote diagnostics, manuals, electrical diagrams, spare-parts list, training, installation support, and warranty | Determines real machine uptime after shipment |
| Delivery and export readiness | Packing design, container plan, port experience, documents, electrical standards, and commissioning plan | Protects the machine through shipment and customs clearance |
A key principle for buyers is this: tonnage is not the same as usable bending capacity. The actual capacity depends on material tensile strength, bend length, V-opening, punch radius, die geometry, grain direction, tool condition, and whether the machine has sufficient crowning compensation.
China's sheet-metal machinery sector combines heavy-machine manufacturing, hydraulic component supply, CNC control integration, metalworking, laser cutting, welding, machining, and export logistics. Important production clusters include:
- Maanshan and Bowang, Anhui: Widely recognized for press brakes, shearing machines, plate rolling machines, press-brake tooling, and other sheet-metal equipment.
- Yangzhou and Jiangsu: Strong machine-tool and industrial-equipment manufacturing capabilities.
- Nanjing and surrounding Jiangsu areas: Active in CNC systems, automation, machinery integration, and export manufacturing.
- Shandong: Important for laser cutting equipment, industrial machinery, fabrication automation, and heavy equipment.
- Guangdong: Strong in automation integration, electronics, metalworking, and downstream fabrication demand.
China's machine-tool exports expanded in 2025, with metal-processing machine-tool exports rising 17.9% year on year to USD 9.68 billion. This reflects a broad base of manufacturing and international demand, but it also creates a crowded supplier market. Some companies are original manufacturers with in-house frame machining and assembly; others are traders, integrators, or brands sourcing machines from partner factories.
Therefore, buyers should confirm exactly who designs, builds, assembles, tests, and services the machine.
This list is a practical shortlist rather than a laboratory ranking. Suppliers serve different customer segments, tonnage ranges, automation requirements, budgets, and export markets. Current capacity, certification status, and machine configuration must be verified directly for each project.
Brand: CNDY-Press
Location: Bowang, Maanshan, Anhui, China
Core Products: CNC press brakes, fibre laser cutting machines, CNC shearing machines, CNC plate rolling machines, CNC grooving machines
Primary Markets: International sheet-metal fabrication, furniture, aerospace-related production, shipbuilding, automotive, steel metallurgy, engineering machinery, bridge construction, and petroleum-related industries

Location: China
Established: 2010
Primary Markets: Automotive, aerospace, electronics, and international custom manufacturing
Core Capability: Precision CNC machining, sheet-metal fabrication, prototyping, small-batch manufacturing, die casting, and related metal-part services
Main Strength: Precision component supply and manufacturing support for press-brake machine builders and sheet-metal equipment projects
Anebon Metal is not principally a standard CNC press-brake manufacturer. It is included because many buyers building a custom fabrication line, private-label machine, tooling system, automation cell, or specialized bending solution also need precision-machined metal components and sheet-metal fabrication support.
Anebon states that it was founded in 2010, is ISO 9001:2015 certified, and provides custom CNC machining, turning, milling, EDM, grinding, die casting, 3D printing, and sheet-metal fabrication services. Its website states tolerances down to ±0.0002 inch, or 0.005 mm, for suitable projects, and identifies customers across automotive, aerospace, and electronics.
For B2B buyers, Anebon may be especially relevant for:
- Custom press-brake parts.
- Precision backgauge components.
- Tooling holders and fixture components.
- Machine enclosures and sheet-metal parts.
- Prototype mechanisms for bending automation.
- Custom brackets, shafts, frames, and machined assemblies.
- Low- to medium-volume OEM equipment components.
Buyers should be clear that a precision component manufacturer and a full press-brake OEM offer different services. Anebon can be useful for custom mechanical development, but a buyer sourcing a complete bending press should verify whether the company is supplying the full machine, supporting a machine-builder partner, or manufacturing only designated components.
Location: China
Primary Markets: Global product-development, prototyping, custom manufacturing, and industrial customers
Core Capability: Rapid manufacturing, CNC machining, sheet-metal fabrication, and prototype-to-production support
Main Strength: Engineering responsiveness for custom metal components and pre-production development
SC Rapid Manufacturing is included as a potential custom-manufacturing resource for buyers that require sheet-metal parts, precision components, prototypes, fixtures, or development-stage support around a bending-machine project.
For example, a buyer developing a special panel-bending cell may need custom operator guards, tooling adapters, enclosure panels, robotic end-effectors, sensor brackets, machine covers, or prototype workholding equipment. A rapid-manufacturing supplier can help validate these components before committing to full-scale production.
However, before selecting SC Rapid Manufacturing for a complete press brake or a production machinery program, verify:
- Whether it directly manufactures full CNC press brakes.
- The scope of its machine-building experience.
- Quality-system certification and certificate validity.
- Available equipment for large frame machining.
- Hydraulic and electrical engineering capability.
- Experience with CE-compliant machine safety systems.
- Capacity for long-term spare-parts supply.
- Factory acceptance testing procedure.
This distinction matters because a supplier that excels at CNC prototype parts may not necessarily have the heavy fabrication, hydraulic, CNC-control, safety-engineering, and field-service infrastructure required for a full bending press machine.
Location: China
Primary Markets: International custom CNC machining and customized manufacturing customers
Core Capability: Custom CNC machining, CAD-file review, design-for-manufacturability feedback, and bespoke part production
Main Strength: Digital file submission and engineering review for custom parts
Fly CNC Part is primarily a custom CNC-machining service rather than a dedicated manufacturer of full bending press machines. Its website states that customers can upload CAD or 3D files, after which the team reviews designs to identify potential issues or improvements before production begins.
For press-brake procurement, Fly CNC Part can be relevant when a customer needs:
- Custom tooling components.
- Machine retrofit parts.
- Backgauge brackets and mounts.
- Fixture plates.
- Custom clamps and adapters.
- Replacement machine components.
- Prototype parts for automated bending cells.
- Customized metal components for distributor or OEM projects.
Buyers should not assume that a company offering CNC-machined parts also builds the complete machine. If the requirement is a full hydraulic press brake, request proof of machine-frame fabrication, stress relief, large-scale machining, hydraulic assembly, controller integration, CE safety systems, testing, and field installation support.

The following table is an initial sourcing tool, not a substitute for a formal technical quotation. Capacity, MOQ, certification, and delivery timing vary by machine type, tonnage, configuration, control system, automation level, and production schedule.
| Manufacturer | Main Focus | Typical Press Brake Scope | MOQ | Certification and Documentation Priority | Best Fit |
|---|---|---|---|---|---|
| Maanshan Deyan Precision Machinery Technology Co., Ltd. / CNDY-Press | Custom sheet-metal equipment | CNC press brakes, laser cutters, shears, rolling and grooving machines | Usually one machine | Request current CE file, electrical drawings, safety documents, factory test procedure | SMEs, distributors, custom OEM/ODM equipment projects |

A purchase specification should start with the workpiece—not with the machine model.
Before requesting quotations, document:
- Material type: mild steel, stainless steel, aluminium, copper, galvanized steel, high-strength steel, or other alloy.
- Maximum material thickness.
- Minimum material thickness.
- Maximum bend length.
- Tensile strength or grade of the material.
- Bend angle and inside radius.
- Product mix and expected daily throughput.
- Short-flange and box-bending requirements.
- Required backgauge accuracy.
- Tooling type and compatibility.
- Automation, robot, or loading requirement.
- Available floor space and crane capacity.
- Electrical supply and voltage.
- Destination-country safety and documentation requirements.
The press-brake force calculation must use the actual material properties. A supplier that quotes the same bending capacity for mild steel and high-tensile stainless steel without adjusting the force calculation is not providing a technically reliable proposal.
The press-brake frame should be fabricated from suitable steel plate, welded under controlled procedures, and stress relieved before precision machining. If residual stress is not controlled, the frame can deform over time, reducing bending consistency.
Ask:
- What steel grade is used?
- Is the frame heat treated, vibration stress relieved, or annealed?
- How are critical surfaces machined?
- What is the frame deflection at rated load?
- Is the bed and ram alignment checked after machining?
Modern CNC press brakes commonly use electro-hydraulic synchronisation, with linear scales measuring ram position on each side of the machine. This can improve repeatability compared with simpler mechanical synchronization designs.
Request:
- Linear scale brand and resolution.
- Hydraulic valve brand.
- Cylinder sealing specification.
- Synchronisation accuracy.
- Repeatability statement.
- Hydraulic-oil cooling or filtration configuration.
- Preventive maintenance recommendations.
When a long workpiece is bent, the bed and ram naturally deflect. CNC crowning compensates for this deflection to help maintain a consistent bend angle across the full length.
For long bends or tight-angle-tolerance work, ask whether the quoted machine includes:
- Mechanical crowning.
- Hydraulic crowning.
- CNC-controlled crowning.
- Automatic crowning calculation linked to the controller.
- Crown-table calibration records.
A CNC control system affects programming, setup time, part repeatability, and operator training. Common controller options may include Delem, ESA, Cybelec, or other systems depending on the supplier and machine package.
Clarify:
- Controller make and model.
- Standard axes included.
- Backgauge configuration: X, R, Z1, Z2, X1, X2, or other axis combinations.
- Offline programming availability.
- 2D or 3D graphical simulation.
- Network connectivity and remote support.
- Operator language options.
- Software licence and update policy.
For European-market press brakes, safety documentation is a core purchasing requirement. A machinery supplier should provide a meaningful CE package rather than only attach a CE mark to the machine.
Hydraulic press brakes are associated with EN 12622:2009+A1:2013, a C-type machinery safety standard covering hydraulic press brakes. Sources discussing current European practice identify EN 12622 as the relevant harmonised reference for hydraulic press brakes, alongside safety requirements derived from machinery legislation.
A credible EU-oriented safety package should include:
- CE Declaration of Conformity.
- Risk assessment.
- Technical file or accessible technical-file information.
- Electrical schematic.
- Hydraulic schematic.
- Machine manual in the destination language where required.
- Emergency-stop circuit design.
- Appropriate guarding.
- Safety laser device, light curtain, or other protective system where applicable.
- Safety-control architecture.
- Operator training information.
- Warning labels and safety signs.
A 2026 industry safety discussion notes that a new hydraulic press brake without compliance to EN 12622:2009+A1:2013 cannot be CE marked for EU sale and identifies safety systems, a technical file, and a Declaration of Conformity as core requirements.
Important: RoHS is generally associated with electrical and electronic equipment rather than being the central machine-safety standard for a press brake. For a bending press machine, procurement attention should focus more directly on machinery safety, electrical safety, EMC requirements where applicable, risk assessment, CE documentation, and country-specific installation rules.
An insider issue in press-brake procurement is that a machine's advertised tonnage may not represent the buyer's real bending capacity.
The capacity changes with:
- Material tensile strength.
- Material thickness.
- Bend length.
- V-die opening.
- Punch radius.
- Air bending versus bottoming or coining.
- Grain direction.
- Tool condition.
- Machine crowning.
- Load position across the bed.
For example, a machine might bend a short mild-steel coupon at its rated tonnage but struggle to achieve a consistent bend on a long, high-tensile stainless-steel part. If the buyer only compares nominal machine tonnage, it may select an undersized machine.
Require each supplier to provide:
1. A bending-force calculation based on your actual material grade and thickness.
2. A machine-selection recommendation showing safety margin.
3. A tooling proposal with punch and V-die dimensions.
4. A drawing showing the intended bend sequence.
5. A crowning recommendation for long parts.
6. A video or factory acceptance test using representative material where feasible.
7. A written statement of allowable off-centre loading.
8. Hydraulic and electrical component lists.
9. A dimensional-accuracy and repeatability statement.
10. A spare-parts package recommendation for the first two years of operation.
Your RFQ should include:
- Required tonnage.
- Working length.
- Material types and tensile strengths.
- Maximum thickness and bend length.
- Drawings or 3D part files.
- Required angle tolerance.
- Production volume.
- Preferred controller.
- Axis configuration.
- Tooling requirements.
- Safety requirements.
- Electrical standard and voltage.
- Installation destination.
- Packaging and shipping terms.
- Required delivery date.
- Operator-training requirement.
- Warranty and spare-parts expectations.
Avoid requesting a quotation using only "100T × 3200 mm CNC press brake." This description does not define the controller, crowning, backgauge, safety system, tool clamps, hydraulic components, or required performance.
Before paying a major deposit, confirm:
- Legal manufacturer name and factory address.
- Factory ownership or actual production relationship.
- Frame-welding and stress-relief process.
- Large-format machining capability.
- Hydraulic assembly area.
- Electrical cabinet assembly.
- Quality-control equipment.
- Test-bending capacity.
- Export packing area.
- Spare-parts storage.
- Engineering and after-sales team.
- Existing installations in similar applications.
A live video factory audit should include random machine areas, not only a polished showroom. Ask to see in-process frames, machining centres, hydraulic assembly, controller wiring, test bending, packaging, and inspection records.
For medium- and high-value machines, agree on a factory acceptance test before production is complete.
The FAT should define:
- Machine model and serial number.
- Controller and axis configuration.
- Tooling included.
- Material used for test bends.
- Bend angle tolerance.
- Repeatability checks.
- Backgauge accuracy.
- Crowning test.
- Safety-device test.
- Hydraulic leak inspection.
- Noise and vibration observation.
- Electrical-function test.
- Manual, drawings, and spare-parts delivery.
- Final packaging inspection.
The buyer should sign the FAT only after all agreed points are completed or formally recorded as open items with a corrective-action deadline.
Press brakes are heavy, high-value machines that require specialized logistics. Buyers should clarify:
- EXW, FOB, CIF, DAP, or DDP Incoterms.
- Machine dimensions and gross weight.
- Container type and loading method.
- Lashing, anti-rust treatment, and vacuum packaging.
- Tooling and accessories packed separately.
- Import duty and customs classification.
- Site foundation and floor-loading requirements.
- Crane or forklift capacity.
- Electrical connection.
- Hydraulic oil requirements.
- Installation and commissioning process.
- Remote or onsite training support.
The final landed cost includes freight, insurance, customs, inland transport, unloading, foundation preparation, electrical work, commissioning, tooling, and maintenance—not only the equipment price.
China offers a broad sourcing base for bending press machines, from standard CNC press brakes for general fabrication to high-tonnage, long-bed, tandem, servo, and automation-ready systems. The correct supplier depends on your sheet-metal material, required bend tolerance, part mix, safety obligations, automation plan, service expectations, and total cost of ownership.
For buyers that value factory-direct communication, flexible equipment configuration, and support for OEM or ODM equipment projects, Maanshan Deyan Precision Machinery Technology Co., Ltd. / CNDY-Press is a supplier worth including in the first stage of technical evaluation. The company provides CNC press brakes and related sheet-metal machinery, while stating that it supports custom manufacturing and OEM/ODM programs.
Request the full certificate and check the legal entity name, factory address, certificate number, certification body, scope, issue date, and expiry date. Then verify it through the certification body's public directory or contact the issuer. Confirm that the scope includes machinery manufacturing or relevant production activities—not only sales or unrelated services.
A basic hydraulic press brake uses hydraulic cylinders to drive the ram and may use simpler synchronization mechanisms. An electro-hydraulic CNC press brake usually integrates CNC control, proportional valves, linear scales, and independently measured ram positions to improve synchronization, repeatability, and programming capability. The correct choice depends on precision needs, production volume, budget, and maintenance capability.
Use a force calculation based on the actual material type, thickness, tensile strength, bend length, V-die opening, and bending method. Add a practical safety margin. Do not choose by nominal tonnage alone. Ask suppliers to provide the calculation and show how the proposed tooling affects force requirements.
At minimum, ask for a CE Declaration of Conformity, machine manual, electrical drawings, hydraulic drawings, risk assessment, safety-system details, warning labels, and information supporting conformity with relevant standards such as EN 12622 for hydraulic press brakes. Confirm destination-market requirements with a qualified local compliance specialist.
Test the final machine configuration, controller, axis movement, backgauge accuracy, bending angle repeatability, crowning function, hydraulics, safety devices, electrical operation, tooling, documentation, and export packaging. Where possible, use your actual sheet material and part geometry.
Yes. Many China-based manufacturers support OEM and ODM projects, but the scope varies. Confirm branding, machine colour, controller language, documentation, labels, packaging, electrical standard, tooling, safety package, warranty responsibility, spare-parts inventory, and change-control rules in the purchase agreement. CNDY-Press states that it supports OEM, ODM, and customer-specific equipment production.
