In the global automobile manufacturing industry, lightweight materials such as plastic, composite material and aluminum alloy have been widely applied to automobile interior parts, exterior decorations and new energy vehicle structural components. However, most lightweight materials have low surface activity, which easily leads to poor adhesion during spraying, printing and bonding processes. Traditional solvent-based chemical primer treatment once was the common solution, yet its high volatile organic compound emission has been strictly restricted by environmental laws in most countries. Low-temperature plasma surface treatment has gradually become the green alternative favored by automobile manufacturers all over the world.
Our atmospheric online plasma processing equipment can realize omnidirectional surface activation for automotive bumpers, instrument panels, plastic trim parts and wire harness connectors. Before painting and gluing, the high-energy plasma can break the inert molecular structure on the material surface, introduce hydroxyl and other active groups, and greatly enhance the surface adhesion of materials. After plasma treatment, automobile parts will not have paint peeling, printing fading and degumming failures in long-term high and low temperature aging tests, which effectively improves the service life and safety of automobile finished products.
Many overseas auto parts suppliers choose our customized plasma automatic production lines for mass production. Compared with traditional chemical treatment workshops that need to be equipped with waste liquid recovery and gas purification devices, the plasma production line only needs conventional power supply and compressed air support, which greatly reduces the customer’s environmental protection investment and daily operation cost. Our equipment can realize unattended automatic operation, equipped with real-time running data recording and fault early warning functions, which is convenient for enterprises to carry out production quality traceability management.We have provided plasma surface treatment technical solutions for more than 800 manufacturing enterprises worldwide. For the automotive industry, our technical engineers will carry out sample testing according to different workpiece materials and processing requirements, formulate the most stable process parameters, and provide remote operation training and lifelong technical after-sales service, helping every auto parts manufacturer complete the upgrading of green production technology smoothly.
