Stage 1: Material Preparation & Core Component Fabrication
High-Quality Raw Material Sourcing: Strictly controlled procurement of aluminum alloys (tubes, fins, headers) and other core materials meeting our specifications and RoHS compliance goals.
2.Precision Tube Cutting: Aluminum tubes are cut to exact lengths using CNC-controlled machines for consistency.
Stage 2: Core Assembly & Critical Joining
3. Core Stacking: Tubes and fins are meticulously layered by hand or automated systems into the specific core configuration designed for maximum excavator cooling efficiency and structural integrity.
4. Fixture & Clamping: The assembled core is placed in specialized fixtures to hold all components in perfect alignment during the joining process.
5. Vacuum Brazing (Primary Method): The clamped core assembly enters a high-temperature vacuum brazing furnace. Under controlled atmosphere and temperature, a precisely applied brazing alloy flows to create strong, leak-proof, and highly conductive bonds between all tubes, fins, and headers.
Stage 3: Tank Assembly & Final Joining
6. Tank Preparation: Tanks are cleaned and prepared.
7. Core-to-Tank Assembly: The brazed core is carefully aligned and fitted to the headers/tanks.
8. Tank Welding: Highly skilled welders (using MIG/TIG processes) or robotic welding systems perform consistent, high-quality welds to join the tanks securely to the core assembly.
Stage 4: Fitting Installation & Pressure Testing
9. Fitting Installation: Inlet/outlet fittings, drain plugs, brackets, and any other attachments are installed and secured.
10. Initial Pressure Test : Every radiator undergoes an initial hydrostatic pressure test well above its operating pressure to detect any leaks or weaknesses in welds or the core immediately.
Stage 5: Finishing & Protection
11. Cleaning & Degreasing: Radiators undergo thorough cleaning to remove flux residues, oils, and contaminants from the manufacturing process.
12. Surface Treatment : Application of protective coatingson tanks and brackets for enhanced corrosion resistance, especially important for excavators exposed to harsh environments.
13. Drying: Complete drying of the unit.
Stage 6: Comprehensive Final Testing & Quality Assurance
14. Final Pressure Test (Verification): A second, often more rigorous, pressure test is performed to confirm integrity after handling and finishing.
15. Flow Testing (If Applicable): Testing to ensure the radiator meets designed flow resistance characteristics.
16. Dimensional Inspection: Critical dimensions and mounting points are verified against specifications.
17. Visual Inspection: Meticulous visual check by QC personnel for surface defects, weld quality, paint flaws, and overall workmanship.
Stage 7: Packaging & Dispatch
18. Careful Packaging: Radiators are securely packaged using protective materials (foam, cardboard, plastic caps for fittings) designed to prevent damage during transit.
19. Warehousing/Shipping: Ready for storage in our climate-controlled warehouse or immediate dispatch via our optimized logistics channels.
