With the development of the economy, consumers are demanding higher and higher performance of automobiles, such as the appearance, operational comfort reliability, and durability of use of automobiles. In order to meet the requirements of consumers, various automobile manufacturers pay more attention to the optimization and improvement of details when producing automobiles, such as conducting
(1) Instrument panels are treated before flexible polyurethane (PU) coating
(2) Control panel before sticky table treatment
(3) Interior PP parts before red tape treatment
(4)Treatment of automotive door and window seals
Previously, without any treatment instrument panel or control panel coating effect is very poor, not wear-resistant, easy to drop paint and other phenomena, with chemical methods of treatment can change the effect of coating, but also changed the performance of the instrument panel and other substrates, making its strength has been reduced. Currently many manufacturers have used plasma car cleaning machine plasma plasma technology to treat these substrates, through plasma plasma bombardment, the material surface micro-level activity enhanced, can significantly improve the coating effect. According to experiments, it is known that different materials treated with plasma cleaners need to choose different process parameters in order to achieve better activation results.
2、Engine oil seal piece
The engine crankshaft oil seal plays a role in preventing the engine oil from leaking out of the engine and preventing foreign objects from entering the engine. The crankshaft oil seal is one of the engine parts, which is in contact with the engine oil at high temperature, so it needs to use the material with excellent heat resistance and oil resistance. At present, the car commonly use PTFE material, with the car performance requirements continue to improve, more and more manufacturers use the material, plasma car cleaning machine its application prospects are very wide. PTFE material has excellent performance in all aspects, high temperature resistance, corrosion resistance, non-stick, self-lubricating, excellent dielectric properties, very low coefficient of friction, but the untreated PTFE material has poor surface activity, one end of which is very difficult to bond with the metal, the product can not meet the quality of metal surface treatment requirements. In order to solve this technical problem, we have to try to change the surface properties of PTFE (polytetrafluoroethylene) bonded to the metal surface, without affecting the performance of the other side. Industry with solution treatment can improve the bonding effect to a certain extent, but it changes the original PTFE properties. Experiments have shown that after plasma cleaning machine plasma bombardment of the PTFE surface to be bonded, its surface activity is significantly enhanced, and the bonding between the metal is solid and reliable to meet the requirements of the process, while the other side maintains its original properties, and its application is increasingly widely recognized.
With the development of the automotive industry, its performance requirements in all aspects are getting higher and higher. Ignition coils have many functions such as boosting power, the obvious effect is to enhance the low and medium speed torque when driving, eliminating carbon, better protecting the engine, extending the life of the engine, reducing or eliminating engine resonance, full fuel combustion and reducing emissions. To make the ignition coil give full play to its role, its quality, reliability, service life and other requirements must meet the standard, but the current ignition coil production process still exists in a big problem ignition coil skeleton outside the epoxy resin pouring, due to the skeleton in the mold before the surface contains a lot of volatile oil, resulting in the skeleton and epoxy resin bonding surface adhesion table is not secure, the finished product in use, ignition instant temperature rise, will be in the When the finished product is used, the temperature of the ignition surface will rise instantly, and bubbles will be generated in the gaps of the bonding surface, which will damage the ignition coil, and in serious cases, an explosion will occur.
Ignition coil skeleton using plasma cleaning machine plasma treatment, not only can remove the surface of the difficult to volatile oil, but also can greatly improve the surface activity of the skeleton, that is, to improve the bonding strength of the skeleton and epoxy resin, to avoid bubbles, and at the same time can improve the welding strength of the enameled wire and skeleton contacts after winding. In this way the performance of the ignition coil in all aspects of the production process is significantly improved, increasing the reliability and service life.
