Custom Sheet Metal Fabrication Parts

KINGKA specializes in high-precision custom sheet metal fabrication parts, delivering durable, fully customized components tailored to your exact requirements. Utilizing advanced manufacturing technologies, we ensure consistent quality and performance for prototyping, small batch, and mass production applications. Our expertise spans a wide range of industries, including industrial automation, telecommunications, consumer electronics, medical equipment, automotive, and aerospace.

Working Principle

Custom sheet metal fabrication involves transforming flat metal sheets into complex components through processes such as laser cutting, CNC bending, stamping, welding, and surface finishing. These processes allow precise control over dimensions, tolerances, and geometries to meet unique customer specifications. Components can function as structural supports, enclosures, brackets, panels, or mounting systems depending on the application.

Manufacturing Process (Typical Steps)

1. Design & Engineering – CAD drawings are reviewed and optimized for manufacturability. Accepted file formats: STEP, STP, IGES, DWG, PDF.

2. Material Preparation – Sheets of stainless steel, aluminum, carbon steel, copper, or brass are inspected for thickness and quality.

3. Cutting & Forming – CNC laser cutting, turret punching, and press braking create the desired shapes and bends.

4. Welding & Joining – MIG, TIG, or spot welding is used for assembly, reinforced by riveting or PEM fasteners where needed.

5. Surface Finishing – Options include powder coating, anodizing, brushing, plating (zinc, nickel), or sandblasting for corrosion resistance and aesthetic enhancement.

6. Inspection & Quality Assurance – In-process checks and final inspections using CMMs, dimensional verification, and visual tests.

7. Packaging & Logistics – Custom packaging and documentation, including bubble wrap, foam inserts, barcodes, QA sheets, and export crates for safe delivery.

Materials Selection

• Stainless Steel: 304, 316 – corrosion resistance, durability

• Carbon Steel: SPCC, Q235, Q345 – cost-effective, high strength

• Aluminum: 5052, 6061, 1060 – lightweight, excellent corrosion resistance

• Galvanized Steel: rust protection for industrial applications

• Copper & Brass: excellent thermal and electrical conductivity

Surface Finishes: Powder coating (textured, matte, glossy), anodizing (clear, black, colored), brushing/polishing, zinc/nickel plating, sandblasting

Lead Time & Cost Analysis

• Prototypes: 5–7 days

• Mass Production: 10–25 days depending on part complexity

• Cost Factors: Material type, sheet thickness, complexity of bends, welding and finishing requirements, and batch size.

KINGKA supports low-volume or one-off production without sacrificing quality, providing scalable solutions from prototypes to mass manufacturing.
