How We Produce
SINRUI's manufacturing process begins in our state-of-the-art workshop, where each radiator is built under a tightly controlled production system. It starts with precision forming of materials and advanced fin assembly, followed by automated high-strength welding for robust frame construction. Each of these critical stages adheres to internationally recognized standards, ensuring structural integrity and thermal efficiency.
Backed by ISO 9001 certified quality management, every radiator must pass a series of rigorous validations—including leak, pressure, and thermal cycling tests—before approval. This end-to-end control guarantees that we deliver products with outstanding durability, stable performance, and consistent cooling reliability, batch after batch.
