Application of plasma treatment machine in automobile industry

1. Ignition Coil

With the rapid development of the automobile manufacturing industry, the performance indicators in various fields are getting higher and higher. The ignition coil has the function of enhancing driving force. The most significant effect is to enhance the torque of low and medium speed gears during driving; remove carbon deposits, better protect the engine, and increase the service life of the engine; reduce or eliminate the resonance phenomenon of the engine; fully assist the combustion of fuel, reduce emissions and many other functions.

After the ignition coil skeleton is treated with plasma cleaning equipment, it can not only remove the non-volatile oil stains on the surface, but also further improve the surface activity of the skeleton, that is, it can enhance the bonding strength between the skeleton and the epoxy resin, prevent the formation of bubbles, and enhance the welding strength of the contact point between the enameled wire and the skeleton after winding. In this way, the performance indicators of the ignition coil in various fields are significantly improved during the production process, and the safety reliability and service life are enhanced.

2. Engine oil seal

The engine half-shaft oil seal prevents the engine oil from leaking out of the engine and prevents dirt from entering the internal structure of the engine. The half-shaft oil seal is one of the parts of the engine. It comes into contact with the engine oil at high temperatures, so it is necessary to use materials with high temperature resistance and oil resistance. At present, high-end cars generally use polytetrafluoroethylene materials. With the continuous improvement of automobile safety standards, more and more manufacturers have begun to use this material, and its application prospects are very broad.

Industrial production often uses sodium chloride solution for cleaning. Although it can improve the bonding effect to a certain extent, it changes the original performance of PTFE. Experiments have shown that after bombarding the PTFE surface to be bonded with a plasma cleaner, its surface activity is significantly improved, and the bonding between the metal material is strong, safe and reliable, which meets the technical standards, while maintaining the original performance. Its application is also increasingly widely recognized.

3. Application of plasma cleaning machine in other aspects of the automotive industry

With the development of the economy, customers have higher and higher standards for the performance of cars, such as the appearance of cars, the comfort of operation, the reliability of systems, and the durability of use. Taking into account the standards of customers, various automobile manufacturers pay more attention to the improvement of details when manufacturing cars, such as:

(1) Correct treatment of the dashboard before the polyurethane (PU) coating of the flexible board;

(2) Correct treatment of the control panel before bonding;

(3) Correct treatment of internal PP parts before planting;

(4) Correct treatment of the sealing conditions of car doors and windows;

At present, many manufacturers have already used plasma cleaning machines to treat these basic materials. By using plasma bombardment, the micro-activity of the surface layer of the raw materials is increased, which can greatly improve the coating effect. According to the test, it is necessary to use different process parameters to treat different materials with plasma cleaning machines in order to achieve better activation effects.
