Surface Treatment of CNC Machining

CNC machining leaves visible tool marks in the process of removing part of the block surface to create the desired shape. If machined parts are not required, choose a finish for your custom parts. At RapidDirect, we offer several common finishes that help improve functionality and aesthetics.

Surface treatment process describe material color
cnc machining and manufacturing services
 - Powder Coating

Powder Coating

Learn More>
The powder coating is sprayed onto the surface of the die casting with a powder spraying equipment. Under the action of static electricity, the powder will be uniformly adsorbed on the surface of the die casting to form a powder coating. After high temperature baking and leveling curing, the powder coating becomes the final coating of different types of powder coatings; the texture can be adjusted to various effects, such as smooth surface, sand texture, foaming, etc. Zinc Alloy/Aluminum Alloy black White

 - Paint


Learn More>
Baking paint is a spray paint production process. The method is to polish the die casting parts to a certain degree of roughness and spray several layers of paint on the substrate, and then bake and set at high temperature. At present, this process has higher requirements for paint and better color rendering. It is mainly divided into two categories: low-temperature baking paint and high-temperature baking paint. The temperature of low-temperature baking paint is between 140°C and 180°C, and the temperature of high-temperature baking paint is between 280°C and 400°C. Depending on the paint, whether to perform low-temperature paint or low-temperature paint is selected. High temperature paint. Zinc Alloy/Aluminum Alloy unlimited color

 - Passivation


Learn More>
Passivation is a process in which a metal is treated in a 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; the protection of non-ferrous metals; and the adhesion of the paint film, etc. Zinc Alloy/Aluminum Alloy White

 - Oxidation


Learn More>
Aluminum alloy surface oxidation, suitable for conductive oxidation, aluminum or aluminum profiles, suitable for anodizing. The oxidation colors of aluminum alloys generally have natural colors and sky blue. Anodizing is carried out under the condition of high voltage electricity, and it is an electrochemical reaction process; conductive oxidation does not need to be energized, but only needs to be soaked in the potion. It is a pure chemical reaction. Anodizing takes a long time, often tens of minutes, while conductive oxidation only takes tens of seconds. 6061/6063/7075 Unlimited colors

 - Electroplating


Learn More>
Electroplating is the process of depositing metal or alloy on the surface of the workpiece by electrolysis to form a uniform, dense and well-bonded metal layer, which is called electroplating. Simple understanding is the change or combination of physical and chemical. Zinc Alloy/Aluminum Alloy Unlimited colors

 - Electrophoresis


Learn More>
E-coat, also known as paint deposition, is a process that uses electricity to attract a painted product to a metal surface. It is usually used alone because it has excellent coverage, but can also be used as a primer for other coatings such as powder coatings. Traditionally, it has been used for functional purposes such as protection, not really decorative purposes. Zinc Alloy/Aluminum Alloy Black/White
cnc machining and manufacturing services - Sandblasting


Learn More>
Sandblasting is to use compressed air as the power to form a high-speed jet beam, and spray abrasives (steel grit, brown corundum, glass beads, emery, etc.) at high speed to the surface of the die casting to be treated, 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 can obtain a certain cleanliness and different roughness, so that the mechanical properties of the surface of the die casting can be improved, thus improving the fatigue of the die casting. It increases the adhesion between it and the coating, prolongs the durability of the coating film, and is also beneficial to the flow and decoration of the coating.

 - Polishing/Grinding


Learn More>
Polishing refers to the processing method that uses mechanical, chemical or electrochemical action to reduce the surface roughness of the workpiece to obtain a bright and flat surface. It is a modification and processing of the workpiece surface using polishing tools and abrasive particles or other polishing media. Zinc Alloy/Aluminum Alloy True color

 -Electrostatic spraying


Learn More>
Under the action of a DC high-voltage electric field, the atomized negatively charged paint particles are directed to the positively charged workpiece to obtain a paint film, which is called static spraying. Zinc Alloy/Aluminum Alloy Unlimited colors
