The core goal of metal and plastic coating is to ensure uniform and aesthetic coatings while enhancing their adhesion and durability, resisting environmental erosion and daily wear. The quality of the coating depends not only on material compatibility but also on the implementation of standardized process techniques. Mastering targeted skills can effectively avoid problems such as sagging, peeling, and abrasion, balancing decorativeness and protectiveness.

Due to significant differences in material properties between metals and plastics, their coating processes have essential distinctions in pretreatment, coating selection, construction parameters, and other aspects. The core goal of coating is to balance protectiveness and decorativeness, and the physical and chemical properties of materials directly determine the direction of process design. Only by accurately adapting to material properties can the coating adhesion, durability, and overall effect be guaranteed.

Metal surface treatment is a key process that optimizes the surface properties of metals through physical, chemical, or electrochemical methods. Its core purposes are to enhance corrosion resistance, wear resistance, aesthetics, and adhesion. The following sorts out the principles and application scenarios of mainstream processes to help you fully understand the core value and applicable needs of various processes.

In the automotive and mechanical manufacturing industry, the corrosion resistance and wear resistance of components directly determine the reliability and service life of the entire machine. The processes of galvanizing, chrome plating, and passivation in metal surface treatment have become the core supporting processes for the manufacturing of automotive mechanical components with precise performance empowerment, laying a solid quality defense line for key components such as crankshafts, gears, and fasteners.

In the field of industrial manufacturing, the service life and performance of metal workpieces largely depend on the quality of surface treatment processes. Among them, anti rust and wear-resistant coating and metal anodizing processing are the core processing technologies, which can not only improve the weather resistance and mechanical strength of metal workpieces, but also adapt to the strict requirements of multiple industries such as automobiles, machinery, electronics, etc., becoming indispensable key processes in the manufacturing process.

In daily use and industrial production, products made of metal and plastic materials often develop surface scratches and abrasions due to collisions and friction. This not only affects the aesthetic appearance but also exposes the base material, leading to corrosion and aging, which shortens the product's service life. However, wear-resistant metal-plastic coating, with its core capability of "resisting scratches and abrasion", builds a protective barrier for products and effectively "extends their service life", making it a key process in the manufacturing of products in fields such as home appliances, automobiles, and electronics.
