What is a Prototype in Sheet Metal Fabrication?

A sheet metal prototype is a tangible version of your design that allows you to validate function, form, and manufacturability before moving to mass production. It helps attract investors and ensures product readiness.

Processes Used in Sheet Metal Prototyping

1. Laser Cutting Service

High-precision fiber laser cutting ensures clean edges and tight tolerances (±0.15mm), ideal for prototyping complex geometries.

2. Water-Jet Cutting

Cold cutting without thermal distortion, perfect for maintaining material integrity.

3. Plasma Cutting

4. Flame Cutting

5. Sheet Metal Stamping

Ideal for producing high volumes of consistent metal parts—brackets, clips, enclosures, and more.

6. CNC Machining

From 3-axis to 5-axis, CNC ensures tight tolerance and precision prototyping in both plastic and metal.

7. Production Etching

High-precision chemical etching offers fast and economical production from prototype to full scale.

8. Sheet Metal Welding

Services include TIG, MIG, spot, laser, and arc welding—ideal for robust assembly.

9. Sanding / Grinding

Removes burrs, improves surface finish, and enhances appearance before finishing.

10. Surface Finishing

Protects parts from corrosion and improves aesthetics—options include anodizing, powder coating, painting, and polishing.

Quality Control of Sheet Metal Fabrication

• Raw Material Inspection: Every batch inspected with chemical and mechanical reports.
• Initial Size Check: Material sizes verified before processing to ensure accuracy.
• Production Monitoring: Process tracked with flowcharts and real-time updates.
• Mid-Term Inspection: Dimensional checks during production to prevent deviations.
• Final QA: CMM and visual checks before packing.
• Surface & Assembly Review: Ensuring cosmetic perfection and assembly fit before shipping.
