Working principle and process of ultra large automotive plasma cleaning machine:

working principle:

It is achieved by emitting a set of high-frequency voltages through a plasma generator and connecting them to a metal cart in a sealed chamber through electrodes. The gas near the metal cart is ionized into a plasma state by the high-frequency electric field formed between the electrodes and the metal cart. The plasma state gas undergoes a chemical reaction on the surface of the metal car door panel. Impurities on the surface of the door panel are turned into particles and gaseous substances, which are pumped out by a vacuum pump to achieve the purpose of cleaning the surface of the door panel.

Workflow:

1. After placing the workpiece to be processed on the pallet of the workpiece trolley, dock it with the host and push the material rack into the vacuum working chamber

2. After closing the vacuum chamber door, start the system

3. Start the equipment vacuum unit; After vacuuming to the set vacuum level, the system releases process gas and turns on plasma; Process until the set time (e.g. 2-5 minutes), the system will stop the plasma and vacuum units; Quickly fill air to break the vacuum

4. Open the vacuum chamber door, dock the car with the host, and pull out the workpiece tray; A work cycle is completed.

Ultra large automotive plasma cleaning machineMain applications:

Car door panel

In the process of automobile door panel processing, in order to increase the aesthetic and comfortable appearance of the door panel, it is necessary to wrap a layer of synthetic leather on the surface of the door panel, which puts forward requirements for the reliability of the wrapping. Cleaning the surface of the door panel can thoroughly remove any small indentations. The door panel is made of heat-resistant and solvent resistant materials, so plasma cleaning is recommended for cleaning the surface of the door panel. Cleaning the door panel can effectively remove impurities remaining due to contamination, thereby improving the reliability of the door panel bonding between the door panel and the skin during subsequent processing.

carbon fibre

With the booming development of the automotive industry and the increasing awareness of environmental protection among people, carbon fiber reinforced thermoplastic resin composite materials have great potential in replacing some automotive steel components due to their excellent mechanical properties, light weight, and recyclability. However, due to its smooth surface and chemical inertness, carbon fiber has poor bonding performance with thermoplastic resins, making it difficult for the mechanical properties of carbon fiber reinforced thermoplastic resin composites to meet the higher safety requirements of automobiles. Therefore, surface modification of carbon fiber is needed to improve the interfacial properties between carbon fiber and thermoplastic resin, and expand the application scope of carbon fiber reinforced thermoplastic resin composites in the automotive manufacturing field. Plasma treatment method uses high-energy particles to etch, oxidize, graft and other effects on the surface of carbon fibers, thereby increasing the surface roughness and polarity of carbon fibers, forming chemical bonds and mechanical interlocking between fibers and resins, which is conducive to enhancing the mechanical properties of materials.
