CNC Machining Surface Treatment

Electroplating

Electroplating is the process of depositing metal or alloy on the surface of a workpiece by electrolysis to form a uniform, dense, and well-bonded metal layer. Simply put, it is a change or combination of physics and chemistry.

Electrophoresis/ E-coat

E-coat, also known as paint deposition, is a process that uses electricity to attract paint products to metal surfaces. It is often used alone because of its excellent coverage, but can also be used as a base coat for other coatings such as powder coating. Traditionally, it has been used for functional purposes such as protection, rather than for decorative purposes.

Passivation

Passivation is the process of treating metal in nitrite, nitrate, chromate or dichromate solution to form a chromate passivation film on the metal surface. It is often used as a post-treatment for zinc and cadmium coatings to improve the corrosion resistance of the coating; protect non-ferrous metals; improve the adhesion of paint films, etc.

Baking paint

Baking varnish is a painting process, which involves spraying several layers of paint on a die-casting that has been polished to a certain degree of roughness, and then baking it at high temperature to set the shape. This process currently has relatively high requirements for paint, and the paint must have good color rendering. It is mainly divided into two categories: low-temperature baking varnish and high-temperature baking varnish. The temperature of low-temperature baking varnish is between 140°C and 180°C, and the temperature of high-temperature baking varnish is between 280°C and 400°C. Whether to use low-temperature baking varnish or high-temperature baking varnish depends on the type of paint being baked.

Powder spraying/coating

Powder spraying is to spray powder coating onto the surface of die castings with powder spraying equipment. Under the action of static electricity, the powder will be evenly adsorbed on the surface of die castings to form a powder coating. The powder coating is leveled and solidified after high-temperature baking to become the final coating with different effects of powder coating; the texture can be adjusted to various effects, such as glossy, sand texture, foaming, etc.

Sandblasting

Sand blasting uses compressed air as the power to form a high-speed jet beam, and sprays abrasives (steel sand, brown corundum, glass beads, corundum, etc.) at high speed onto the surface of the die-casting to be processed, so that the appearance of the outer surface of the die-casting changes. Due to the impact and cutting effect of the sand on the surface of the die-casting, the surface of the die-casting obtains a certain degree of cleanliness and different roughness, and the mechanical properties of the surface of the die-casting are improved, thereby improving the fatigue resistance of the die-casting, increasing the adhesion between it and the coating, extending the durability of the coating, and also facilitating the leveling and decoration of the coating.

Oxidation

Aluminum alloy surface oxidation is suitable for conductive oxidation, and aluminum or aluminum profiles are suitable for anodizing. The oxidation colors of aluminum alloys are generally natural color and sky blue. Anodizing is carried out under high voltage, and it is an electrochemical reaction process; conductive oxidation does not require electricity, but only needs to be immersed in the potion, and it is a pure chemical reaction. Anodizing takes a long time, often tens of minutes, while conductive oxidation only takes a few tens of seconds.

Polishing/Grinding

Polishing refers to a processing method that uses mechanical, chemical or electrochemical effects to reduce the surface roughness of a workpiece to obtain a bright and smooth surface. It is a modification process of the workpiece surface using polishing tools and abrasive particles or other polishing media.
