Abstract: In the field of mechanical manufacturing, the durability of parts directly determines the lifespan and reliability of the products. Galvanization, as a classic, efficient, and cost-effective metal surface treatment process, provides excellent rust and corrosion protection for steel parts. This article will deeply explore all aspects of galvanizing for mechanical processing parts, including its core principles, detailed comparisons of various processes (electro-galvanizing, hot-dip galvanizing, mechanical galvanizing, etc.), the protective mechanism of the galvanized layer, advantages and disadvantages analysis, subsequent treatments (such as passivation, phosphating), quality inspection standards, and how to select the most suitable galvanizing process based on the characteristics of your parts, helping you equip precision-machined parts with the strongest “armor”.

In the field of precision manufacturing, part polishing is a crucial step that determines the performance, lifespan, and appearance of products. Whether it is the core components of automotive engines, the precise components of medical devices, or the micro parts of electronic equipment, after professional polishing treatment, not only can the surface smoothness be improved, the friction loss be reduced, but also the corrosion resistance be enhanced, laying a solid foundation for subsequent assembly and use. This article will start from the basic understanding of part polishing, deeply analyze the mainstream polishing processes, material adaptation schemes, common problem solutions, equipment selection techniques, and industry development trends, providing comprehensive and practical reference guidelines for manufacturing enterprises, technicians, and procurement professionals.
