Raw material control: Each batch of raw materials is supplied with qualification certificates. We test for forging crystal changes and conduct three-stage stress tests for sealing and pressfit products.
Rigorous testing process: Products are certified by ISO9001 and AS 3688 Australia standards. We monitor raw material processing, annealing, and final packaging strictly.



Our production spans over 20,000 square meters. Through years of pursuit of excellence, we have evolved into a modern, large-scale enterprise. Our products range from single copper refrigeration parts to thousands of items covering heating, machine fittings, and valves.
