The Chinasheng 9s System: Forging Superior Leakproof Quality Through Nine Core Technologies

In the field of industrial manufacturing, product reliability and durability directly determine a company's core competitiveness. CHINASHENG, through its independently developed 9S System, has systematically integrated nine core technological processes to establish a scientific, rigorous, efficient, and reliable quality assurance system for leak prevention, setting a new industry benchmark for product quality.

I. Double Leakproof Testing: The Ultimate Validation of Quality
The system begins with inspection and ends with inspection. CHINASHENG has implemented strict leakproof tests at both the start and the finish. The initial Anti-leakage test screens raw materials and early-stage components. At the end of the manufacturing process, a more stringent 15-minute, double-pressure Anti-leakage test acts as the final gatekeeper before shipment, simulating extreme pressure conditions far exceeding normal operation, ensuring every unit leaving the factory delivers on the promise of zero leakage.

II. Precise Design and High-Standard Materials: The Foundation of Excellence
Any superior manufacturing process begins with superior design and materials. Precise design relies on advanced international software like HTRI Exchanger for simulation analysis and leakproof design, providing the theoretical guarantee for the product's structural integrity from the very source. Meanwhile, High standard material entails the strict use of German standard AlMg2.5 alloy. Its excellent corrosion resistance and mechanical strength effectively extend the product's service life under complex working conditions, eliminating leakage risks caused by material defects at the fundamental level.

III. Core Manufacturing Processes: Key Steps Empowered by Technology
Advanced concepts and superior raw materials must be transformed into reality through top-tier manufacturing processes. CHINASHENG has deployed four key technologies in the core manufacturing stages:

1. Vacuum brazing: Utilizing HAF70100 and VW-S-1410 model brazing furnaces, this process achieves perfect molecular bonding of metals in an oxygen-free vacuum environment, creating dense and uniform seams. This is the decisive process determining the core sealing performance of the product.

2. Deep cleaning: Before and after welding, the fourth-generation vacuum modified alcohol cleaning machine is used to thoroughly remove oil, oxides, and impurities from component surfaces. This provides an absolutely clean interface for brazing, preventing any welding defects caused by contamination.

3. Automatic assembly: Through fully automatic assembly machines, key components are pressed and positioned with millimeter-level precision. This eliminates uncertainties and errors inherent in manual operation, ensuring a uniformly high sealing standard at the assembly level.

4. Three-in-one argon arc welding: For specific critical areas, this is performed by welding masters with over 10 years of experience. They precisely control the arc, gas flow, and wire feeding to achieve high-quality sealed welds, representing the perfect fusion of craftsmanship and advanced technology.

IV. High-Precision Forming and Machining: Meticulous Attention to Detail
CHINASHENG shows no compromise even concerning the minute details that affect heat transfer efficiency and structural strength.

• Zero tolerance fin pushing molding: The use of the servo-type RM-D417 fin forming machine ensures the precise shape, spacing, and angle of every single fin. This not only optimizes thermal performance but also enhances overall mechanical strength and leak resistance through its uniform structure.

• Automatic CNC machining center: High-precision, low-tolerance machining of key interfaces and planes by CNC machining centers guarantees perfect fit between components, eliminating potential leak points caused by dimensional deviations.

The CHINASHENG 9S System is far from a simple list of nine independent steps; it is an interlinked, layered, organic whole. Starting from testing and validation, progressing through careful design and material selection, empowered by core technologies like brazing, cleaning, assembly, and welding, and ultimately pursuing perfection in the details of forming and machining, it constructs a comprehensive leakproof ecosystem spanning the product's entire lifecycle. This system ensures that every CHINASHENG product is not merely an industrial component, but a trustworthy, durable commitment to quality, creating lasting and stable value for customers.
