Custom Precision CNC Bending Aluminum Chassis
Custom precision CNC bending aluminum chassis manufactured strictly according to your engineering drawings, dimensions, assembly requirements, and production specifications.
Designed for electronic equipment, industrial controls, communication systems, test instruments, power equipment, automation systems, and OEM products that require a chassis tailored to their internal components.
Custom Aluminum Chassis Built Around Your Equipment
Optimized Assembly: Mounting holes and cutouts align with your approved layout, eliminating issues such as PCB mounting errors, connector interference, or tight component clearance.
CAD Driven: Production is based directly on customer-supplied 2D drawings (DWG, DXF, PDF) or 3D CAD models (STEP, IGES).
Comprehensive DFM Review: Every design undergoes a thorough Design for Manufacturability (DFM) review prior to production to evaluate material thickness, bend radii, hole-to-bend distances, tolerances, and hardware clearance.
Key Features & Capabilities
Advanced CNC Press Brake Bending
High-precision CNC press brakes form aluminum sheets according to programmed bend sequences. Multi-bend geometries are calculated considering material springback, bend radii, and sheet thickness to ensure exact dimensional accuracy.
Precision Cutouts & Hole Features
Features are laser-cut or CNC-punched in the flat pattern prior to bending, ensuring proper alignment across formed panels:
- PCB mounting holes & slots
- DB9, RJ45, USB, HDMI & custom connector cutouts
- Display, switch, LED, and button openings
- High-airflow fan grills & ventilation slots
- Cable entry grommet holes & internal routing tabs
Integrated Fasteners & Internal Hardware
Automated hardware installation helps streamline final assembly:
- PEM Threaded Studs, Nuts & Standoffs
- Threaded Mounting Rivets & Inserts
- Welded or Riveted Internal Support Brackets

FAQ
Q: Can the aluminum chassis be manufactured according to our drawings?
A: Yes. Custom chassis can be manufactured from customer supplied 2D engineering drawings or 3D CAD files. The drawing should define the required material, thickness, dimensions, tolerances, bends, holes, cutouts, hardware, and surface finish where applicable.
Q: Can PCB mounting holes and internal standoffs be added?
A: Yes. PCB mounting holes, standoffs, threaded inserts, mounting tabs, and internal brackets can be incorporated according to the equipment layout.
Q: Can connector and display cutouts be customized?
A: Yes. Connector openings, display windows, switch holes, LED openings, fan openings, cable entries, and ventilation slots can be produced according to the approved drawing.
Q: What aluminum thickness can be used for the chassis?
A: The appropriate thickness depends on the aluminum alloy, chassis dimensions, bend geometry, required stiffness, component weight, mounting loads, and application conditions. The required thickness can follow the customer's drawing or be reviewed during the engineering stage.
Q: What affects the dimensional accuracy of a bent aluminum chassis?
A: Dimensional results can be affected by material properties, sheet thickness, bend radius, tooling, bending sequence, part geometry, and the programmed bending process.
Q: Can the chassis be powder coated or anodized?
A: Depending on the aluminum material and project requirements, powder coating, anodizing, brushing, or other specified surface treatments may be available.
Q: Can prototypes be produced before a larger production order?
A: Yes. Prototype production can be used to verify PCB fit, connector alignment, internal clearance, mounting locations, hardware installation, and assembly sequence before repeat production.
Q: What information is needed to start a custom aluminum chassis project?
A: A 2D engineering drawing or 3D CAD file is the best starting point. Material, thickness, quantity, tolerances, surface finish, hardware requirements, and application information should also be provided when available.
