Sheet Metal Enclosures & Chassis

Detailed Description

Our custom sheet metal enclosures and chassis are precision-fabricated structural components designed for electronic equipment, industrial control systems, communication devices, power supplies and machinery assemblies. Each enclosure can integrate complex cutouts, ventilation holes, mounting points, cable openings, formed ribs, internal brackets and fastening structures according to customer drawings.

The manufacturing process combines laser cutting or CNC punching with precision press brake bending, riveting, welding and surface finishing. Multiple panels can also be assembled into complete chassis structures with controlled hole positioning and repeatable mounting geometry. Custom dimensions, sheet thicknesses, internal structures and surface finishes are available for both prototype verification and batch production.

Available Surface Finishes

• Powder Coating: Typical 60–100 μm protective coating with customizable colors, suitable for industrial equipment housings.
• Anodizing: Protective and decorative treatment commonly used for aluminum enclosures.
• Zinc Plating: Corrosion-resistant metallic coating suitable for carbon steel components.
• Brushed Finish: Directional surface texture for stainless steel or aluminum exterior panels.

Structural & Functional Breakdown

• Multi-bend Enclosure Structure: Precision folded walls and flanges create rigid box-shaped structures while reducing the number of assembled components.
• Integrated Ventilation Structure: Round holes, slots, louvers and custom perforation patterns can be incorporated for heat dissipation.
• Internal Mounting Structure: Supports threaded holes, PEM nuts, studs, brackets and locating features for PCB, power supply and mechanical component installation.
• Reinforced Chassis Structure: Embossed ribs, folded edges and formed flanges improve stiffness while maintaining relatively low sheet thickness.

Key Machining Highlights

• Precision Laser Cutting: Typical cutting tolerance of ±0.10–0.15 mm supports complex openings and accurate component positioning.
• CNC Press Brake Forming: Multi-angle bending with typical ±1° angle tolerance supports complex enclosure geometries.
• Integrated Assembly Capability: Riveting, spot welding, TIG welding and mechanical fastening can be combined according to enclosure design.
• Full Drawing-based Customization: Supports STEP, STP, DWG, DXF and PDF drawings for prototype and batch manufacturing.
