Complete Exhaust System Mechanical performance Test

It is the only third-party laboratory in the industry that has the capability to test the mechanical performance of a complete exhaust system. With more than 10 years of experience in mechanical test of exhaust systems, it has provided services to 100 major OEMs and after-treatment related companies, and has also worked and maintained long-term business cooperation with GM, Guangzhou Automobile, Dongfeng, Chang'an, Geely, Faurecia, Tenneco, Katcon, Weifu Lida and other enterprises. It provides effective services for enterprises in terms of reliability life test, production consistency test, failure product improvement, and part selection. The company also organized relevant companies in the industry, and developed standards for exhaust system related parts such as GB/T 25983-2010, QC/T 1075-2017, and T/CAEPI 12.5-2017. Targets include catalytic converters for gasoline vehicles (chassis, tight-coupling, manifold), diesel exhaust after-treatment devices (SCR, DOC, DPF, etc.), manifolds, mufflers, EGR coolers, and the relevant cushions, substrates, metallic bellows and other key components of exhaust after-treatment system.
