1. Design Review – We examine your CAD files and suggest improvements for manufacturability
2. Material Selection – Choosing the right metal type and thickness for your application
3. Programming – Creating the CNC bending sequence for optimal results
4. Tooling Setup – Selecting and installing the appropriate dies and punches
5. First Article Inspection – Measuring the first piece to verify dimensions
6. Production Run – Completing your order with consistent quality
7. Final Inspection – Checking finished parts against specifications
8. Finishing and Packaging – Adding any required treatments and secure packaging

Benefits of CNC Sheet Metal Bending

Precision and Consistency

Our CNC press brakes deliver repeatable results with tolerances as tight as ±0.2mm. This ensures that all your parts will fit together properly during assembly.

Material Efficiency

CNC bending creates complex shapes without removing material, making it more cost-effective than processes like milling or cutting for many applications.

Design Flexibility

With bend radii ranging from 0.5T to 6T (where T is the material thickness), we can create a wide variety of forms to match your design requirements.

Strength and Durability

The bending process can actually strengthen the metal along the bend line, creating more durable parts than other manufacturing methods for certain applications.

Cost-Effectiveness

For high-volume production runs, CNC sheet metal bending offers significant cost savings compared to other fabrication methods, especially for parts with multiple bends.

Real-World Applications

Automotive Brackets

We produce lightweight aluminum brackets with precise angles that support critical vehicle systems. These parts undergo rigorous testing to ensure they meet automotive industry standards.

HVAC Ducts and Transitions

Our bending capabilities create perfect seams in HVAC components, improving airflow efficiency and reducing noise in building systems.

Electronics Enclosures

We make EMI-shielded housings that protect sensitive electronics from interference while providing access points and mounting features precisely where needed.

Industrial Machinery Guards

Our 12mm-thick steel guards with precise bends protect workers from moving machinery parts while maintaining access for maintenance.

Architectural Elements

We create decorative and functional metal components for buildings, including trim pieces, rain guards, and structural supports.

Advanced Bending Techniques

Multi-Bend Sequencing

We optimize the bend sequence to achieve complex geometries without tool interference or material damage.

Hemming

Our machines can create folded edges (hems) that eliminate sharp edges and reinforce the edge of the sheet metal.

Box and Pan Bending

We use specialized tooling to create box-like structures with multiple bends from a single sheet of metal.

Custom Angle Bending

Our systems can create non-standard angles to precisely match your design requirements, not just 90° bends.

Bump Bending

For larger radius bends than our tooling directly allows, we use a series of small bends to create smooth curves.

Quality Control Measures

Our quality assurance processes include:

• Laser measurement for angle verification (±0.1° accuracy)
• 3D scanning of completed parts to verify against CAD models
• Material certification verification before processing
• First article inspection with full dimensional reporting
• In-process monitoring with statistical process control

Through our precision CNC machining approach, we ensure your parts meet or exceed specifications.

File Preparation Guidelines

For the best results with our CNC sheet metal bending services:

• Submit files in DXF format with bend lines clearly marked
• Include material type and thickness in your specifications
• Specify required bend radius and angle tolerance
• Note any critical dimensions that must be maintained after bending
• Identify any holes or features that must be positioned relative to bends

Our engineering team will review your files and provide feedback if we see potential issues or improvements.
