Surface treatment

Surface treatment is a method used to improve the state of a part’s surface and its mechanical, physical or chemical properties. Generally, products manufactured by casting, injection molding and other mechanical processing methods, so most of them need to be further cleaned, hardened, ground, polished, painted or electroplated on all or part of the surface to improve various characteristics of the surface. Smoothness and aesthetics.

4 types of surface treatment process

Surface treatment is a process of artificially forming a surface layer on the surface of a base material with mechanical, physical and chemical properties different from the base, in order to meet the corrosion resistance, wear resistance, decoration or other special functional requirements of the product

Electrochemical surface treatment

Electrochemical surface treatment: anodizing, electrochemical polishing, electroplating

Modern surface treatment

Modern surface treatment: chemical vapor deposition CVD, physical vapor deposition PVD, ion implantation, ion plating, laser surface treatment, etc.

Mechanical surface treatment

Mechanical surface treatment

Mechanical surface treatment includes sandblasting, shot blasting, polishing, rolling, polishing, brushing, spraying, painting, oiling, etc.

Chemical surface treatment

Chemical surface treatment

Chemical surface treatment: blue and black, phosphating, pickling, chemical plating of various metals and alloys, TD treatment, QPQ treatment, chemical oxidation, etc.

Surface Finish Specification

Our surface treatment specifications are differentiated for metal casting parts and plastic injection molding parts, and surface treatment methods can be selected according to different characteristics of different materials.

Metal surface finishing specifications

Anodizing

Mainly the anodic oxidation of aluminum is to use electrochemical principles to form a layer of Al2O3 (aluminum oxide) film on the surface of aluminum and aluminum alloy. This oxide film has special properties such as protection, decoration, insulation, and wear resistance.

ED-Electrophoresis deposition

ED-Electrophoresis deposition

Used in stainless steel, aluminum alloy, etc., can make the product present various colors, and maintain the metallic luster, while enhancing the surface properties, with good anti-corrosion performance.

Micro Arc Oxidation (MAO)

Micro Arc Oxidation (MAO)

The process of applying a high voltage in an electrolyte solution (usually a weakly alkaline solution) to form a ceramic surface film layer is the result of the synergistic effect of physical discharge and electrochemical oxidation.

Physical vapor deposition（PVD）

Physical vapor deposition（PVD）

It is an industrial manufacturing process, which mainly uses physical processes to deposit thin films.

Electroplating

It is a technology that uses electrolysis to attach a layer of metal film to the surface of the metal to prevent corrosion, improve wear resistance, conductivity, reflectivity and enhance the appearance.

Metal wire drawing

Metal wire drawing

It is a surface treatment method that forms lines on the surface of the workpiece by grinding products to achieve a decorative effect. According to the different textures after wire drawing, it can be divided into: straight wire drawing, chaotic wire drawing, corrugated, and swirling.

Sand blasting

It uses compressed air as the power to form a high-speed jet beam to spray the spray material onto the surface of the workpiece to be treated at high speed, so that the appearance or shape of the outer surface of the workpiece surface changes, and a certain degree of cleanliness and different roughness are obtained. a craft.

Polishing

Polishing

The finishing process of the surface of the workpiece by using flexible polishing tools and abrasive particles or other polishing media.

Etching

Etching

Usually refers to etching, also known as photochemical etching, which refers to removing the protective film of the area to be etched after exposure to plate making and development, and contacting chemical solutions during etching to achieve the effect of dissolution and corrosion, forming concave-convex or hollow-out molding.

Plastic part surface finish specification

In-Mold Decoration-IMD

In-Mold Decoration-IMD

Put the patterned diaphragm into the metal mold, inject the resin for molding into the metal mold and join the diaphragm, so that the printed patterned diaphragm and the resin are integrated and solidified into a mold. A method of forming a finished product.

Painting

Painting

A coating method in which the paint is atomized with a spray tool such as a spray gun and sprayed on the workpiece to be coated.

NCVM

Also known as discontinuous coating technology or non-conductive electroplating technology, it uses thin films such as metal and insulating compounds, and uses the discontinuous characteristics to obtain a final appearance that has a metallic texture and does not affect wireless communication transmission. .

Plastic electroplating

Plastic electroplating

Make plastics obtain metal effect surface with high yield and low cost. Similar to PVD, PVD is a physical principle, and electroplating is electroless plating, which is mainly divided into vacuum electroplating and water electroplating.

Plastic parts printing

Plastic parts printing

It is a process of printing the required pattern on the surface of plastic parts by means of pad printing, screen printing, transfer printing, etc.

Laser engraving

Laser engraving

also called laser engraving or laser marking, is a surface treatment process using optical principles, similar to screen printing and pad printing, through which laser engraving can be used to type or pattern on the surface of the product.

Bite pattern

Bite pattern

It is a process method in which chemicals such as concentrated sulfuric acid are used to corrode the inside of the plastic molding mold to form lines in the form of snake lines, etch lines, plowing lines, etc. After the plastic is formed through the mold, the surface has corresponding lines.
