Application of plasma cleaning equipment in the automotive field

With the fluctuation of the global economy and the continuous changes in market consumption capacity, the automotive industry has significantly reduced prices this year. In the context of consumers' increasingly cautious consumption mentality and limited purchasing power, competition in the automotive industry has become particularly fierce.

Under the premise of such price competition, car manufacturers need to reduce manufacturing costs in order to increase market share, which has become a consensus in the industry.

Plasma cleaning technology, as an emerging surface treatment technology in the automotive industry, can improve the quality of dispensing, bonding, adhesion, welding, coating, and packaging, meet the strict production requirements of the automotive industry, and improve product yield for automotive manufacturers, achieving the goal of cost reduction and efficiency improvement.

Plasma cleaning technology uses a high-frequency power source to ionize plasma, and the active particles in the plasma undergo physical or chemical reactions with the material surface to improve its surface properties, such as increasing wettability and reducing surface tension.

Compared with traditional flame methods, plasma cleaning machines have the advantages of uniform treatment effect, no open flame room temperature treatment, materials that are not easily burned or deformed, environmentally friendly and pollution-free, and have a wide range of applications.

Automotive interior and exterior parts generally have non planar shapes such as bends and bumps. Before painting, bonding, and coating processes, plasma cleaning machines are often used to treat the surfaces of automotive interior parts, instrument panels, storage boxes, sunroof rails, headlights, and other interior and exterior parts, ensuring the quality of subsequent processes. The application effect of plasma cleaning machine in the automotive field is significant. Through the physical bombardment and chemical action of plasma, it can effectively improve the surface properties of materials and solve the problems that traditional cleaning processes are difficult to handle.

Next, let me introduce to you the types of automotive interior accessories that plasma cleaning machines can be used for, and their respective functions!

1. Automotive sensors: The application of sensors in the automotive field is becoming increasingly widespread, and the performance requirements for various aspects are becoming higher. For example, the reliability of the bonding and sealing between the outer shell and internal electronic components is very important.

The use of plasma surface treatment can improve the surface energy of related materials, increase adhesive strength, avoid the generation of bubbles, and ensure the reliability and service life of sensors.

2. Power battery PCBA board: The automotive power battery PCBA board can be cleaned and activated using atmospheric plasma before dispensing, welding, and packaging, which enhances the bonding strength and ensures the quality of the subsequent dispensing, welding, and packaging processes.

3. Plasma cleaning and activation treatment before bonding plastic interior accessories can improve surface wettability and ensure bonding quality.

4. Automotive ignition coil: The plasma cleaning machine can thoroughly remove pollutants such as oxides and release agents from the surface of automotive components. Plasma cleaning can also achieve ultra clean surfaces at the 0.01 μ m level, effectively improving the cleanliness of components.

5. Before gluing car headlights: For example, plasma cleaning can improve the adhesion and wear resistance of coatings in the pre-treatment of car interior painting. In the manufacturing of car lights, plasma treatment can enhance the adhesion between the lens and the adhesive, avoiding fogging.

In summary, low-temperature plasma cleaning machines can remove oxides and impurities from automotive welding parts, improve welding quality and reliability. Plasma cleaning machines do not require the use of chemical solvents, avoiding environmental pollution caused by solvent evaporation in traditional cleaning methods. At the same time, plasma cleaning has fast processing speed, low energy consumption, and can significantly reduce production costs. 

The plasma cleaning machine can be applied to a variety of materials, including plastics, rubber, metals, glass, etc. Whether it is large-sized, complex shaped components or precision electronic components, plasma cleaning machines can effectively process them and have become an indispensable surface treatment technology in automotive manufacturing.
