Production Process

Our production process is designed to ensure structural strength, dimensional accuracy and consistent quality for both large welded structures and standard sheet metal parts.

1. Technical Review & Engineering
Customer drawings and technical requirements are reviewed by our engineering team to confirm materials, structure, welding methods and process feasibility before production.

2. Material Preparation
Raw materials are selected according to specifications and inspected before cutting to ensure material quality and traceability.

3. Laser Cutting & Tube Processing
Sheet metal and tubes are processed using laser cutting equipment to achieve accurate profiles and clean edges, providing a solid foundation for further fabrication.

4. Bending & Forming
Parts are formed through CNC bending and rolling processes to meet design requirements and ensure dimensional consistency.

5. Welding & Assembly
Components are assembled and welded using MIG, TIG, laser welding or robotic welding, depending on structural requirements. Welding quality and deformation control are closely monitored during this stage.

6. Machining & Finishing
Machining operations such as drilling, tapping, milling and turning are carried out where precision interfaces or assembly surfaces are required.

7. Surface Treatment
Surface treatments are applied based on product requirements, including grinding, polishing, brushing, sand blasting, powder coating and painting, to improve appearance, corrosion resistance and durability.

8. Inspection & Quality Control
Dimensional checks, visual inspection and welding inspection are performed before packing to ensure products meet technical requirements.

9. Packing & Dispatch
Products are packed according to size and structure, ensuring protection during handling and transportation.
