China remains one of the world's most important sourcing bases for CNC sheet metal press brakes, hydraulic press brakes, servo-electric bending machines, laser cutting systems, shearing machines, and integrated sheet-metal production lines. For international buyers, the advantage is not simply a lower machine purchase price. It is the ability to choose among highly specialized industrial clusters, from flexible OEM-oriented machine builders in Ma'anshan to large-scale intelligent equipment producers in Yangzhou and Jiangsu.
However, choosing a supplier is more complicated than comparing tonnage, bending length, axis count, and a quotation. A press brake is a long-life capital asset. Its real cost is determined by frame rigidity, hydraulic-system reliability, CNC controller configuration, tooling compatibility, commissioning quality, spare-parts availability, and the supplier's ability to support the machine after it arrives at the buyer's facility.
This guide evaluates 10 suppliers and supplier types for procurement teams looking for a long-term manufacturing partner—not merely the lowest initial price.
Important note: The sequence below is a practical sourcing-oriented comparison, not an official revenue ranking. Some listed companies specialize in complete press-brake equipment, while others are more relevant for custom sheet-metal parts, rapid manufacturing, prototype support, or component outsourcing. Buyers should verify the current scope, certifications, production capacity, and export capability directly before placing an order.
China's press-brake manufacturing ecosystem combines machine-tool production, structural welding, hydraulic engineering, CNC control integration, tool-and-die supply, electrical assembly, and export logistics. This creates a sourcing environment where buyers can procure an individual CNC hydraulic press brake or build a complete metal-fabrication solution that includes:
- CNC press brakes and tandem press brake systems
- Fiber laser cutting machines
- Hydraulic shearing machines
- Plate rolling machines
- V-grooving machines
- Press-brake punches and dies
- Robotic loading and bending cells
- Sheet-metal enclosures, cabinets, brackets, and OEM parts
- Installation, operator training, remote diagnostics, and spare-parts support
The country's machine-tool export profile has continued to expand. Industry reporting cited China as accounting for 19% of global machine-tool exports in the first half of 2025, highlighting the scale of its manufacturing and export base. China's machine-tool industry also recorded total import and export value of US$33.48 billion in the reported period, with year-on-year growth of 5%.
For press-brake buyers, two industrial areas are especially relevant:
| Industrial cluster | Typical strengths | Suitable buyer profile |
|---|---|---|
| Ma’anshan / Bowang, Anhui | CNC press brakes, shears, laser systems, plate rolls, V-grooving equipment, press-brake tooling, flexible customization | Buyers needing cost-effective machines, OEM/ODM configurations, fast communication, or bundled sheet-metal equipment |
| Yangzhou / Jiangsu | Large metal-forming equipment manufacturers, automated lines, high-end CNC systems, servo technology, enterprise-scale production | Automotive, appliance, construction machinery, high-volume fabrication, and automation-oriented projects |
| Wuxi / Jiangsu | Sheet-metal equipment, industrial automation, precision forming, mature supplier networks | Buyers requiring established engineering resources and broader equipment integration |
| Shenzhen / Guangdong | Precision manufacturing, electronics supply chains, rapid prototyping, custom parts | Buyers that need sheet-metal parts, prototypes, low-volume runs, or equipment-linked component support |
A major benefit of sourcing from China is supplier segmentation. A buyer can work with a large enterprise for an automated bending cell, a mid-sized manufacturer for an export-ready CNC press brake, and a more flexible OEM partner for customized configurations, private labeling, special tooling, or integrated equipment packages.
A reliable press-brake supplier should be assessed using evidence rather than a polished website or a low initial quotation. The following criteria reflect how experienced procurement teams evaluate manufacturers for long-term cooperation.
A buyer should confirm whether the supplier is an actual manufacturer, an exporter, a trading company, or a hybrid organization. A capable manufacturer should be able to explain its fabrication, machining, welding, stress-relief, painting, assembly, hydraulic testing, electrical wiring, calibration, and final-inspection process.
For a CNC press brake, factory capability matters because key quality variables are created before the CNC controller is installed:
- Frame steel grade and plate thickness
- Weld-joint quality and weld procedure control
- Stress-relief method after welding
- Machining accuracy of ram guides and worktable
- Synchronization system design
- Hydraulic component brand and traceability
- Backgauge structure, servo configuration, and repeatability
- Electrical cabinet layout and safety components
- Final bend-test records and machine acceptance documentation
Press-brake engineering should go beyond assembling standard purchased components. Strong suppliers can discuss:
- Hydraulic versus servo-electric architecture
- Electro-hydraulic synchronization systems
- Crowning methods and compensation requirements
- Delem, Cybelec, ESA, or comparable CNC controller options
- 2-axis, 4-axis, 6-axis, or higher-axis backgauge systems
- Tandem synchronization for long workpieces
- Tooling compatibility and segmented-tool design
- Bending-sequence programming and collision avoidance
- Automation interfaces for robot cells or material handling
Buyers should request documentation for structural steel, hydraulic parts, electrical components, CNC controllers, servo motors, safety components, and factory acceptance testing. A supplier's ISO 9001 certificate alone does not prove every machine is properly made, but it can be a useful part of a larger verification process.
For export projects, buyers should also determine whether the machine requires:
- CE conformity documentation for applicable EU market requirements
- Electrical documentation in the buyer's required language
- A risk assessment and safety-system description
- User manuals, hydraulic diagrams, electrical drawings, and spare-parts lists
- Country-specific electrical compatibility, including voltage and frequency
- RoHS documentation where relevant to supplied electrical or electronic components
A press brake that is mechanically sound but poorly commissioned can still become a costly production bottleneck. Buyers should examine:
- Normal lead time and peak-season lead time
- Pre-shipment inspection procedures
- Export packing method and container-loading plan
- Remote commissioning capability
- Availability of overseas technicians or local service partners
- Spare-parts stock and response time
- Training materials for operators and maintenance teams
For distributors, machinery brands, and medium-sized fabricators, OEM/ODM support can be more valuable than a large catalog. Key questions include:
- Can the supplier support private labels, machine colors, logos, manuals, and packaging?
- Can it modify bending length, tonnage, controller, backgauge, tooling, safety package, or electrical specifications?
- Can it supply a complete production-cell configuration?
- Can it provide non-standard tooling or custom dies for the buyer's parts?
- Can it assist with product positioning, installation documents, and spare-parts kits for a regional dealership?

The following table is a sourcing-positioning guide rather than a verified production-capacity ranking. "MOQ" for press brakes is generally one machine, while custom parts suppliers may use different batch requirements. Every buyer should request written, current confirmation.
| Rank | Supplier | Core focus | Typical production fit | Likely MOQ approach | Certifications / compliance to verify |
|---|---|---|---|---|---|
| 1 | Maanshan Deyan Precision Machinery Technology Co., Ltd. / CNDY-Press | CNC press brakes and complete sheet-metal equipment | Flexible custom machines, OEM/ODM, bundled equipment solutions | Usually 1 machine for standard equipment; confirm for OEM branding | CE, ISO system, electrical safety documents, model-specific test reports |
| 2 | Anebon Metal | Precision CNC machining and hardware manufacturing | Components, fixtures, custom parts, precision machining | Prototype to repeat batches; confirm by part complexity | ISO 9001:2015 stated; material and inspection records |

A 100-ton, 3-meter press brake from two suppliers may have very different real-world performance. Buyers should evaluate the machine structure and configuration behind the nominal tonnage.
Ask for the following information:
- Nominal pressing force in tons or kilonewtons
- Maximum bending length
- Distance between side frames
- Throat depth
- Ram stroke and daylight opening
- Backgauge travel range and axis configuration
- Ram synchronization type
- Table crowning method
- Main-motor and hydraulic-system configuration
- CNC controller model and software functions
- Tool-clamping method
- Machine weight
- Structural drawings or machine-layout drawings
- Standard and optional safety systems
Bending force is not fixed. It changes with material tensile strength, sheet thickness, bend length, V-die opening, grain direction, and desired bend radius.
For air bending, a simplified estimation formula is often expressed as:
P=1.42×σb×L×t2/V
Where:
- P = required bending force
- σb = tensile strength of the material
- L = bend length
- t = material thickness
- V = V-die opening
This formula is only an engineering starting point. A supplier should calculate the required tonnage using the buyer's actual material grade, thickness tolerance, bend length, and tooling geometry.
For example, a buyer bending mild steel, stainless steel, aluminum, and high-strength steel cannot assume that the same press-brake tonnage will deliver the same result. Stainless steel and high-strength steels generally require more force than standard mild steel at equivalent thickness and bend geometry.
A capable supplier should ask what materials you will bend. Common examples include:
- Mild steel / carbon steel
- Galvanized steel
- Stainless steel, such as 304 or 316
- Aluminum alloys
- Copper and brass
- High-strength low-alloy steel
- Pre-painted or coated sheet
- Perforated sheet
- Thin decorative stainless steel
The supplier should also ask about sheet thickness range, maximum bend length, bend-angle tolerance, inside bend radius, production volume, and whether surface marks are acceptable.
For decorative stainless steel, appliance panels, painted sheet, or polished materials, buyers may require non-marking tooling, protective film handling, special die geometry, or lower-friction tool surfaces. These details should be part of the technical agreement—not an informal post-order request.
One industry issue that experienced buyers often discover too late is that two suppliers may quote what appears to be the same component brands while delivering very different machine quality.
For example, a quotation may list a well-known CNC controller, hydraulic valve, servo motor, or electrical component brand. That does not automatically confirm:
- The component is genuine and sourced through an authorized channel.
- The component is the same model or performance tier.
- The machine frame was machined to the precision required for that component.
- The hydraulic manifold, piping layout, electrical wiring, and parameter setup are correctly engineered.
- The supplier has the capacity to support the component after delivery.
Ask the supplier to include the exact component model numbers—not only brands—in the technical annex. Then request:
- Close-up photos of nameplates before shipment
- Component serial numbers where available
- Original manuals or certificates
- A final configuration list signed by both parties
- Hydraulic-system test records
- CNC parameter backup files
- A factory acceptance test video using your specified workpiece
- A spare-parts quotation for the first 12–24 months
This approach turns a vague "Bosch-Rexroth / Delem / Siemens / Schneider or equivalent" promise into a verifiable procurement specification.
Some quotations emphasize tonnage and controller features but provide little information about frame design, plate thickness, machining, or stress relief. A weak or poorly processed frame can affect long-term bending consistency.
How to reduce the risk: Request machine weight, frame drawings, welding-process information, stress-relief method, machining photos, and actual bending-test records.
The supplier may initially quote premium components but substitute alternatives during manufacturing.
How to reduce the risk: Attach a detailed bill of materials to the contract. Include brand, model number, quantity, voltage, and approved alternatives. Require written approval for substitutions.
A CE mark on a machine does not itself prove that the product is appropriate for the buyer's market or that all applicable documentation is complete.
How to reduce the risk: Request the Declaration of Conformity, technical-file information, risk assessment, electrical schematics, safety-device details, and model-specific documentation. Confirm that the legal manufacturer name matches the supplier you are contracting with.
A supplier may demonstrate a bend test using thin mild steel while the buyer actually needs stainless steel, galvanized sheet, or high-strength material.
How to reduce the risk: Provide a test matrix before production. Specify material grade, thickness, width, bend length, angle, radius, tolerance, tooling, and measuring method.
The press brake may be capable of the required force, but unsuitable punches and dies can make the actual part impossible or inefficient to produce.
How to reduce the risk: Send 2D and 3D part drawings early. Ask for a bending-sequence review, tooling proposal, collision-risk analysis, and estimated cycle time.
Large machines require correct blocking, moisture protection, export packing, lifting plans, and installation preparation.
How to reduce the risk: Define Incoterms, packing standard, container-loading photos, insurance responsibility, destination-port process, unloading equipment, foundation requirements, electrical preparation, and commissioning scope.
A strong RFQ should include:
- Required tonnage and bending length
- Material grades and thickness range
- Maximum workpiece dimensions
- Production volume and shift pattern
- Required axis configuration
- Preferred controller brand or acceptable alternatives
- Tooling requirements
- Voltage, frequency, and plug standard
- Required safety standards
- Target delivery date
- Required documentation and language
- Shipping destination and preferred Incoterm
- Requested warranty and spare-parts package
The lowest equipment price can become the highest total cost if it creates downtime, tooling rework, commissioning delays, or expensive service dependence.
For a high-value purchase, conduct either an on-site factory audit or a detailed live video audit.
During the audit, ask to see:
- Steel plate storage and material identification
- Welding area
- Stress-relief equipment or outsourced-process evidence
- Large machining centers
- Assembly stations
- Hydraulic-system assembly
- Electrical wiring area
- Testing area
- Completed machines awaiting shipment
- QC documentation
- Packaging area
- Spare-parts storage
For CNDY-Press and other Ma'anshan suppliers, an on-site visit can also help buyers compare different factories within the same machinery cluster and determine which organization offers the most suitable combination of flexibility, technical communication, and equipment scope.
The factory acceptance test should be written into the purchase agreement. It should identify:
- Machine model and serial number
- Workpiece material specification
- Thickness and bend length
- Required bend angle and tolerance
- Number of repeat bends
- Backgauge positioning test
- Hydraulic and electrical-system test
- Safety-device test
- Included tooling
- Inspection method
- Video and report requirements
- Approval criteria
A press brake purchase is not complete when the machine leaves the factory. Plan for:
- Import duty and customs requirements
- Wooden-crate or containerized packing requirements
- Heavy-lift equipment at destination
- Site foundation and floor load
- Electrical input and grounding
- Hydraulic oil requirements
- Technician travel requirements, if applicable
- Operator training
- Spare-parts inventory
- Preventive-maintenance schedule
China offers a wide range of sheet metal press brake sourcing options, from large automation-focused equipment groups to flexible OEM/ODM manufacturers and specialized custom-part suppliers. The right supplier is not necessarily the biggest brand or the lowest-priced quote. It is the company that can demonstrate a suitable technical configuration, transparent manufacturing process, stable delivery plan, valid compliance documentation, and practical after-sales support.
For buyers seeking a flexible equipment partner in the Ma'anshan manufacturing cluster, Maanshan Deyan Precision Machinery Technology Co., Ltd. / CNDY-Press is worth considering for customized CNC press brakes and broader sheet-metal production equipment. Its stated OEM/ODM capabilities, multi-machine product range, and focus on technical support make it particularly relevant for distributors, small and medium-sized fabrication businesses, and brands requiring non-standard or private-label solutions.
Before making a final decision, submit your drawings, material specifications, target throughput, electrical requirements, and preferred machine configuration to at least three qualified suppliers. Compare their engineering responses, not just their final prices. A supplier that asks detailed process questions early is often more likely to deliver a machine that performs reliably after installation.
Ask for a complete copy of the certificate, including the certificate number, legal entity name, factory address, certification scope, issue date, and expiration date. Then verify it with the issuing certification body or through the accreditation path shown on the document. Confirm that the name on the certificate exactly matches the company signing your sales contract. A valid ISO certificate does not automatically prove a specific machine meets your requirement, but it helps confirm the supplier's documented quality-management system.
Both matter, but frame quality is often underestimated. Tonnage indicates nominal forming force; it does not fully describe stiffness, deflection behavior, ram-guide accuracy, machining precision, or long-term stability. Ask for machine weight, frame construction, stress-relief method, crowning system, and test data under your actual bending conditions.
Provide the supplier with 2D part drawings, 3D models, material information, bend sequence, and required production volume. Ask for a proposed bending sequence, tooling layout, collision simulation, and CNC programming screenshots or video. This is especially important for deep boxes, narrow flanges, U-shaped profiles, return bends, and complex multi-bend workpieces.
No. You should verify that the CE documentation applies to the exact model and configuration being shipped. Ask for the Declaration of Conformity, applicable standards, electrical diagrams, safety documentation, risk assessment, emergency-stop design, light curtain or laser protection arrangement, and user manual. If automation or special tooling is added, confirm whether the documentation still covers the complete delivered system.
At minimum, discuss a first-year or two-year spare-parts kit covering filters, seals, electrical fuses, relays, contactors, sensors, key hydraulic-service items, and critical consumables. For remote regions, buyers should also consider backup components with long replacement lead times, particularly for CNC controls, servo drives, hydraulic valves, encoders, and safety devices. The final list should reflect the specific machine configuration and the availability of local service.
