Surface treatment of injection molding precision parts is a critical step to ensure part performance, appearance and durability. The following are several common surface treatment methods for injection molding precision parts:
First, polishing is a common surface treatment. It uses mechanical, chemical or electrochemical effects to reduce the surface roughness of parts, thereby obtaining a bright and smooth appearance. Polishing not only improves the aesthetics of the parts, but also reduces surface defects and increases the wear and corrosion resistance of the parts.
Secondly, electroplating is also an important surface treatment method. Electroplating increases the hardness, wear resistance, and corrosion resistance of a part by electrochemically depositing a layer of metal or alloy on its surface. This treatment not only improves the performance of the part, but also adds a beautiful metallic sheen to it.
In addition, coating treatment is also one of the commonly used methods. It changes the color, gloss and texture of parts by coating them with a special chemical. This treatment not only enhances the appearance of the part, but also provides it with additional protection and enhances its durability.
In addition, thermal spraying and sputtering processes are also common technologies for surface treatment of injection molding precision parts. Thermal spraying transfers paint to the surface of the part through heat conduction to form a covering film, while the sputtering process uses high-energy particles or ions to bombard the surface of the material to melt and deposit it on the part. These processes can effectively improve the hardness, wear resistance and corrosion resistance of parts, and give them special functionality.
Finally, sandblasting is also a common surface treatment method. It uses fine particles of sand to be sprayed onto the surface of the part to remove dirt, oxide layers and scratches on the surface. Sandblasting can make the surface of the part smooth and even, and increase its surface hardness and wear resistance.
To sum up, there are various surface treatment methods for injection molding precision parts, and each method has its unique application scenarios and advantages. In practical applications, the appropriate treatment method can be selected according to the specific needs of the part and the use environment to obtain the best surface treatment effect.
