The appearance of the workpiece is inseparable from the design, color, material and process, of which the surface treatment process is the most direct reflection of the appearance of the product. Surface treatment can improve the appearance, texture, function and other aspects of product performance.

The commonly used surface treatment methods in the manufacturing and processing industry are: electroplating, painting, screen printing, surface drawing, sandblasting, oxidation, polishing, radium carving and so on.

electroplate

Through chemical reaction, attach a layer of other metals on the surface of the material to increase the corrosion resistance of the metal, and can achieve a certain beautifying appearance, is a commonly used surface treatment, such as: galvanizing, nickel plating, etc.

spray

Spraying is the most common surface treatment, whether it is plastic or hardware. Spraying generally includes oil spraying, powder spraying, etc., the most common is oil spraying.

Sprayed coatings, commonly known as paints, are composed of resins, pigments, solvents, and other additives. Plastic spraying generally has two paints, the surface color is called the top paint, the most surface transparent layer is called the protective paint.

Baking paint

Through spraying, high-temperature baking and other methods, a layer of various colors of paint is sprayed on the surface of the material to beautify the appearance and increase the corrosion resistance of the material.

There are generally two kinds of liquid baking paint and powder baking paint, of which powder baking paint is the most common. The paint surface is non-conductive. Areas with EMC requirements are not allowed to paint (paint products generally reserve spraying margin...) .

printing

A process of printing patterns on plastic surfaces by pad printing, screen printing and transfer.

Surface drawing

The material is placed between the upper and lower rollers of the wire drawing machine, the roller is attached with a sand belt, driven by the motor, so that the material passes through the upper and lower sand belt, pulling out a trace on the surface of the material, according to the different sand belt, the thickness of the trace is not the same, the main role is to beautify the appearance. Generally, aluminum is considered to use brushed surface treatment.

sandblast

Through the wind of the sand blasting machine, the sand is hit to the surface of the workpiece, forming a layer of dense pits on the surface of the workpiece, the main function is to remove the dirt on the surface of the workpiece, increase the adhesion of the surface of the workpiece, and prepare for the subsequent surface treatment.

oxidation

The metal on the surface of the workpiece is oxidized to form a dense protective film on the surface of the workpiece to increase the corrosion resistance of the workpiece. There are generally two ways of conducting oxidation and anodizing, which is a common surface treatment method, such as the anodizing of the surface of the radiator (which can have different colors).

polishing

Polishing refers to the use of mechanical, chemical or electrochemical action to reduce the surface roughness of the workpiece to obtain a bright, flat surface processing method, is the use of polishing tools and abrasive particles or other polishing media on the surface of the workpiece modification processing.

Polishing can not improve the dimensional accuracy or geometric accuracy of the workpiece, but for the purpose of obtaining a smooth surface or mirror gloss, and sometimes to eliminate gloss (extinction).

Laser carving

Also known as laser engraving or laser marking, is a surface treatment process using optical principles. The high-intensity focused laser beam emitted by the laser is used at the focal point to oxidize the material and thus process it.

etching

Usually referred to as etching, also known as photochemical etching, refers to the removal of the protective film of the etched area through exposure platemaking and development, and contact with chemical solution during etching to achieve the effect of dissolution corrosion, forming a concave and convex or hollow forming effect.
