YanMing factory's Metal Surface Treatment Processes Introduction

YanMing provides a full range of professional metal surface treatment processes to meet the diverse needs of different products and industries. The detailed introduction of each process is as follows:

Etching

Remove the protective film in the area to be etched, and let it contact the chemical solution during etching to achieve the effect of dissolution and corrosion, forming concave-convex or hollowed-out patterns on the metal surface. It is widely used in electronic components (such as etched nameplates, circuit boards), hardware accessories, automotive parts, and precision instruments, suitable for batch processing of complex patterns.

Polishing

Using mechanical, chemical or electrochemical effects, as well as polishing tools, abrasive particles or other polishing media, the surface roughness of the workpiece is reduced to obtain a bright and flat surface. It is commonly applied to stainless steel products, aluminum alloy parts, hardware decorations, and medical equipment, enhancing the product’s appearance and surface smoothness.

Brushing

The reciprocating movement of the brushing cloth is used to rub back and forth on the surface of the workpiece to improve the surface finish of the workpiece, with straight textures on the surface. It can improve the surface quality and cover slight scratches on the surface. It is widely used in household appliances (refrigerators, air conditioners), automotive interior parts, aluminum panels, and digital product casings.

Laser Engraving

Based on numerical control technology and laser as the processing medium. The processing material undergoes instantaneous melting and gasification physical denaturation under laser engraving irradiation, which enables laser engraving to achieve the processing purpose. It is suitable for marking, coding and pattern carving on metal products, such as electronic product shells, hardware tools, automotive parts, and precision molds.

Electroplating

Using electrolysis to make a metal film adhere to the surface of metal or other material workpieces, so as to prevent metal oxidation, improve wear resistance, conductivity, reflectivity, corrosion resistance and enhance beauty. It is widely used in electronic components, automotive parts, hardware accessories, jewelry, and marine equipment.

Oxidation

In a narrow sense, metal oxidation refers to the process of metal combining with oxygen to form oxides. In a broad sense, metal oxidation refers to the process in which metal loses electrons and thus the positive atomic valence increases (M → Mⁿ⁺ + ne⁻). It is mainly used for aluminum alloy products (such as automotive parts, architectural profiles), magnesium alloy components, and aerospace parts to improve corrosion resistance and surface durability.

Electrophoresis

It is the abbreviation of electrophoresis phenomenon, which refers to the phenomenon that charged particles move towards the electrode with opposite electrical properties under the action of an electric field. It is a technology that uses the different moving speeds of charged particles in the electric field to achieve separation. It is commonly used in automotive parts (paint electrophoresis), hardware accessories, electronic components, and furniture hardware to form a uniform and wear-resistant surface film.
