Wire Harness Sealing Test—Yue Xin’s Air-Tightness Testing Equipment Makes Full Inspection at Changchun Jieyi Easier

Transaction Date: September 2018	Customer Location: Changchun
Test Requirement: IP67 Testing for Automotive Wiring Harnesses	Equipment Selection: Airtightness Testing Equipment / Dust-Proof Test Chamber / Water-Immersion Tank

Changchun Jieyi has been dedicated to the automotive industry for over a decade, and the company consistently adheres to… Adhering to the marketing philosophy of “Quality, Service, and Integrity,” the company consistently refines product functionality and continually enhances the quality and responsiveness of its after-sales service. This approach has significantly advanced its management practices and overall operational standards. Backed by a distinctive market vision and a bold spirit of innovation, the company has maintained an upward trajectory, establishing itself as a leading manufacturer of automotive wiring harnesses and interior components. 。

As a professional manufacturer of automotive wire harnesses, Changchun Jieyi has always placed great emphasis on quality control. During discussions with Yuexin, Jieyi’s quality manager noted that their wire harnesses had previously been subjected to water‑immersion testing—a practice that lacked rigor and professionalism. This time, they plan to invest in a comprehensive set of equipment to truly implement… We’ve purchased all the equipment needed to conduct IP67 dust‑ and water‑resistance testing, so we no longer have to worry about others claiming our tests aren’t rigorous enough. In addition, LiuGong has stated that its wire harnesses must undergo 100% inspection to ensure quality control, with only those meeting the required sealing performance being allowed to leave the factory.

Yue Xin Company specializes in doing… IP waterproofing test equipment—our current product lineup primarily includes waterproof testing devices, dust‑proof testing equipment, and air‑tightness testing systems. Although this order from Jieyi was quite time‑critical (with a delivery deadline of just 10 days), it posed no challenge for Yuexin. Thanks to our advanced material management system, the production team at Yuexin completed assembly and commissioning within one week of receiving the order and delivered the equipment directly to the customer’s premises three days later.

During a follow-up visit, I heard from LiuGong that they were truly grateful this time—under normal circumstances, the delivery schedule wouldn’t have been so tight. The main reason was that a major client was conducting a factory audit, which made the timeline particularly urgent. Fortunately, they had chosen your company; had they gone with another supplier, failing to meet the deadline would have had serious repercussions. Thank you, Yuexin Company.
