Zhengzhou Zhongyuan Silande DIN6701 bonding system audit successfully passed, helping the development of domestic rail transit

In August 2023, according to the scheduled plan, Shanghai Yifa Company conducted a certificate renewal audit for Zhengzhou Zhongyuan Silande High tech Co., Ltd., a well-known enterprise in the domestic adhesive industry, for the bonding system DIN6701 of the rail transit industry. The company's relevant work met the standard requirements and successfully obtained the next stage certificate.

This audit is our first audit of Zhengzhou Zhongyuan Silande Company on behalf of the European Adhesive Standards Committee, upgrading from DIN6701 to EN17460 standard. The audit focuses on the operation documents, on-site operations, personnel qualifications and training, contract review, and other aspects during the bonding process. The audit found that the company has standardized, clear, stable, and effective processes from incoming materials to inspection, personnel training, operating procedures, and document execution.

It is worth mentioning that in this audit, in addition to the bonding system work, the pride of the company's early pioneering in the domestic industry and the substitution of similar imported products, the emphasis and resilience of the company's product development, and the advanced layout of future development directions and technological routes have left a deep impression on the audit team teachers.

Zhengzhou Zhongyuan Silande High tech Co., Ltd., established in 1983, is one of the veteran enterprises in the domestic adhesive industry. The company's products such as polysulfide, organosilicon, butyl sealant, and structural adhesive film have been practically used for several years, even decades. In the field of rail transit, the company's epoxy structural adhesive, flame retardant sealant, structural adhesive film and other products have achieved stable use and wide recognition in multiple host factories, door and interior accessory supporting factories of CRRC Group, as well as customers in the aviation industry. The issuance of the new EN17460 certificate this time is a gift presented to the company's 40th anniversary, hoping that the company will continue to work hard and make greater and longer lasting contributions to the development of China's rail transit, aviation and other fields.
