At KT, we specialize in custom sheet metal components for thermal management and system integration. Unlike standard brackets, this multi-fan mount demonstrates our ability to handle complex geometries, where precise bend sequencing and feature alignment are critical. We focus on producing parts that simplify assembly, improve structural rigidity, and enhance long-term reliability in high-vibration environments.
🛠️ Production Workflow
- Complex Laser Cutting: The process starts with laser cutting the steel sheet, creating fan grille patterns, mounting holes, and the irregular outer profile in one step. This ensures clean, consistent edges and precise positioning for every feature.
- Multi-Step CNC Bending: The flat blank is then formed into its 3D shape using a multi-axis CNC press brake. The stepped mounting arms and offsets require carefully programmed bend sequences to ensure each angle is accurate and the final assembly fits perfectly into the equipment chassis.
- Hardware Insertion: Rivet nuts or threaded inserts are press-fit into the mounting holes, providing strong, reusable fastening points for the fans. This eliminates the need for loose fasteners and simplifies on-site assembly.
- Surface Treatment & Curing: The bracket undergoes cleaning, phosphate treatment, and black powder coating. The coating is then cured at high temperature to form a hard, uniform layer that resists scratches, chemicals, and corrosion.
- Final Quality Assurance: Dimensional checks, bend angle verification, coating thickness testing, and fastener pull tests are performed to ensure the bracket meets all tolerance and performance specifications.
