Haoyin has obtained ISO 9001 quality management system certification and implements a three-level inspection mechanism (raw materials → semi-finished products → finished products) throughout the production process. Various methods such as online pressure testing, tightness testing, and dimensional visual recognition systems are adopted to ensure that each batch of products passes strict screening before delivery.
The ex-factory qualification rate of products remains stable at over 99%. Testing equipment covers performance dimensions such as air tightness, burst pressure, and salt spray corrosion resistance.
We support certification docking with third-party testing institutions (such as CSA, CE, etc.).
We have flexible manufacturing capabilities, enabling quick switching of production tasks for various specifications and interface types to meet the customization needs of customers in different regions. We accept small-batch trial production with a minimum order quantity of 100 pieces, quickly respond to customer's drawing or sample modification requirements, and support customization of parameters such as length, interface form, thread specification, and sheath material.
