Recently, the company's independently developed 10L integrally injection-molded accumulator bladder product has successfully completed a one-million-cycle fatigue lifespan test under the industry’s highest and most extreme conditions, after having already passed the 100,000-cycle fatigue lifespan test required by the national standard GB/T 20663-2017 Accumulator Pressure Vessels. This marks the comprehensive engineering validation of the high-fatigue-life accumulator bladder product and represents an innovative breakthrough in the field of integrally injection-molded premium bladders.
Fatigue lifespan testing for accumulator bladders involves high difficulty and stringent equipment requirements. The company’s R&D project team conducted on-site research and collaborated with a university to develop specialized testing equipment for bladder fatigue life, simulating real working conditions to evaluate the product's durability. Throughout the testing process, the team encountered numerous technical bottlenecks and challenges but persisted, learning from failures and continuously refining their approach. During this period, the project lead maintained close communication with the customer to review test indicators and referenced the fatigue test conditions established by France’s SACATEC, setting the test parameters as follows: bladder pre-charge pressure of 6 MPa, minimum working pressure of 10 MPa, maximum working pressure of 20 MPa, and a test frequency of 6–10 cycles per minute.
In response to various unexpected issues during testing, team members promptly communicated and collaborated to troubleshoot equipment problems, working closely with the testing equipment manufacturer. After six months of negotiation and experimentation, the fatigue lifespan test for the accumulator bladder product was recently completed, yielding reliable and authentic test data and generating a professional test report. This achievement fills a domestic gap in accumulator bladder fatigue lifespan testing and provides strong support for capturing the premium accumulator market.
In recent years, with strong support from company leadership at all levels, the division has continued to advance in the field of premium accumulator bladder products, delving into new sectors and markets. Through continuous innovation and optimization of product formulations and performance, while closely monitoring domestic and international rubber market demands, the team has concentrated efforts on translating market needs into technological achievements. This progress provides robust support for the company’s future expansion in rubber product and accumulator business development.
