The development trend of non-metallic materials technology is high performance, high functionalization, compounding, intelligent and green. Because of the new requirement of technology and the high requirement of products, and customers have different understanding of demanding products and processes, the failure of non-metallic material components such as fracture, cracking, corrosion and discoloration often occurs, which often leads to responsibility disputes between suppliers and users, and consequently leads to serious economic losses. Furthermore, more and more enterprises and units have a new requirement for failure analysis of non-metallic materials. They are no longer the conventional means such as direct replacement, but need to find out the root cause and mechanism of failure by means of failure analysis to improve product quality, process improvement and liability arbitration.
Manufacturers of non-metallic materials:In-depth study of the design, production, process, storage, transportation and other stages of the possible causes of product failure, and its failure mechanism, in order to provide a basis for improving product yield and optimizing production process.
Assembly plant:Responsible arbitration; improve assembly process; provide quality assistance for supplier incoming inspection.
Distributor or agent:To provide favorable evidence for quality responsibility and to define its responsibilities fairly.
Whole machine users:Improve product technology and reliability, and enhance core competitiveness of products. Main failure modes (but not limited to) common failure analysis techniques such as fracture, cracking, corrosion, delamination, foaming, coating peeling, discoloration, wear failure, etc.
