Company Introduction

Fin-shaping is the first process in radiator production:
1. Our company operates 12 new-generation fin-shaping machines capable of producing all fin types currently required for radiators;
2. The most commonly used fin types include JC, BY, BW, PZ, and DK;
3. Fin height can be freely adjusted as long as the corresponding sealed bar height is available;

The vacuum modified alcohol cleaning process is the second step in radiator production:
The thoroughness of cleaning directly impacts the brazing quality of the core assembly. If contaminants remain on component surfaces, the solder cannot fully melt and bond, resulting in weak connections between parts. This compromises the overall performance and service life of the heat exchanger.
 

The assembly process is the third stage of production:
1. Cleaned fins, separators, and sealed bars must be placed in the fin holding area. All cleaned components must be assembled on the same day. If special circumstances (e.g., power outage) prevent their use that day, cover them with clean white cloth to prevent contamination.
2. The assembly room maintains a constant temperature of 24°C (75°F) year-round, with humidity controlled between 20% and 30%.

Vacuum brazing process is the fourth production process:
1. Assembled cores must be placed in the brazing holding area, with all assembled cores to be brazed within the same day.
2. Brazing is the most critical process in the entire radiator production cycle. The quality of brazing directly impacts the radiator's performance and service life.

CNC Machining Process is the fifth production process:
1. In this process, all machining of components required for the radiator is completed, including hole punching on end caps, thread drilling, sheet metal cutting, and other operations;
2. Building upon traditional turning, milling, planing, and grinding equipment, our company has introduced CNC machining centers, enhancing production efficiency and achieving 100% compliance with all dimensional tolerances.

Argon arc welding is the sixth production process:
1. The company currently has 20 TIG welders and 2 automated welding robots;
2. All radiator components (end caps, joints, mounting plates, cores) are assembled in this process;
3.The argon arc welding imposes stringent requirements on operators, encompassing both aesthetic standards (welds must be straight, uniform, and visually appealing) and technical specifications (welds must be free of defects such as porosity, slag inclusions, or weld spatter).

Pressure leakage testing is the seventh production process:
1. Pressure leakage testing serves as the acceptance inspection in radiator manufacturing, comprising both hydrostatic pressure leakage testing and air tightness testing. Test pressure is typically set at 1.5 times the working pressure.
2. For hydrostatic testing, the radiator is filled with water, pressurized, and held at pressure for 30 minutes. This checks for cracks or ruptures, verifying the structural integrity of the radiator.
