At KT, we specialize in custom sheet metal fabrication for electronic and industrial applications. From simple brackets to complex enclosures, we combine precision laser cutting, CNC bending, and high-quality surface treatments to deliver aluminum components that meet your exact design requirements. For power supply applications, we focus on three core goals: ensuring efficient thermal dissipation, providing reliable structural support, and enhancing long-term corrosion resistance.
🛠️ Production Workflow
- Laser Cutting: The process begins with precision laser cutting of the aluminum sheet. This creates clean, burr-free ventilation slots, mounting holes, and the outer profile of the enclosure, ensuring high accuracy even for complex geometries.
- CNC Bending: The cut aluminum sheet is formed using CNC bending to create the enclosure’s 3D shape, including vertical sides, mounting flanges, and angled brackets. Consistent bend angles ensure proper fit and alignment during assembly.
- Deburring & Surface Preparation: Sharp edges and residual burrs from cutting and bending are removed, and the part is thoroughly cleaned to prepare it for the anodizing process.
- Black Anodizing: The enclosure undergoes black anodizing, forming a hard, protective oxide layer on the aluminum surface. This enhances corrosion resistance, improves wear resistance, and provides a uniform, matte black finish.
- Final Inspection & Quality Control: Dimensional verification, bend angle checks, and finish quality assessments are performed to ensure the enclosure meets tolerance and performance requirements.

✅ Core Advantages
- Optimized Thermal Management: The precisely cut ventilation slots enable efficient air flow, helping to dissipate heat from power supply components. This reduces operating temperatures and improves the device’s reliability and lifespan.
- Lightweight Yet Rigid Construction: Aluminum offers an excellent strength-to-weight ratio, making the enclosure lightweight while still providing sufficient rigidity to protect internal components from impact and vibration.
- High Precision & Assembly Compatibility: Laser cutting ensures accurate slot profiles and mounting hole positions, while CNC bending delivers consistent angles and dimensions. This results in parts that fit together seamlessly during assembly.
- Durable, Scratch-Resistant Finish: Black anodizing provides superior corrosion resistance, protecting the aluminum from oxidation and environmental damage. It also adds a professional, scratch-resistant matte finish that enhances both durability and aesthetics.
