Modern cars now use 100kg of plastic material, replacing the previous 200-300kg of traditional metal, resulting in a significant weight reduction. This is crucial for energy conservation and a decrease in greenhouse gas emissions. Statistics show that there are now dozens of types of plastic used in cars, with the average plastic usage accounting for 5-10% of the vehicle's total weight. As the demand for car lightweighting grows and the application of automotive plastic technology expands, the per-vehicle usage of plastic is expected to increase further in the future. This also aligns with the current trend of low-carbon economy!

On modern vehicles, you can find the presence of plastic components everywhere, from exterior trim pieces (such as bumpers, mudflaps, wheel arches, and air deflectors), to interior trim (like dashboards, door panels, side consoles, glove compartment lids, seats, and rear guards), and even in functional and structural parts (such as fuel tanks, radiator water chambers, air filter covers, and fan blades).

Automotive Parts Plastic Welding Technology

Automotive applications requiring plastic components necessitate corresponding plastic welding techniques. In the automotive industry, welding is a critical process in the manufacturing of automotive parts and bodies, playing a unique role of bridging the gap between the two. Additionally, the wide variety of vehicle models, complex forming structures, specialized and standardized production of components, and the comprehensive requirements for quality, efficiency, and cost in automotive manufacturing all determine that automotive welding is a multi-disciplinary, cross-domain, and highly integrated production process.

Automotive plastics are divided into two categories: thermosetting plastics, which can withstand ordinary baking paint operations, and thermoplastic plastics, which offer easy and rapid processing advantages. In terms of automotive plastics, the top seven plastic materials and their respective proportions are as follows: Polypropylene 21%, Polyurethane 19.6%, Polyvinyl Chloride 12.2%, Thermosetting Composite Materials 10.4%, ABS 8%, Nylon 7.8%, Polyethylene 6%.

Nicoco specializes in ultrasonic welding equipment for automotive interior and exterior trim parts, as well as thermal plate welding equipment for cars, vibration friction welding machines, and high-frequency welding machines for main carpet leather in cars. These are commonly used for automotive components such as headlights, instrument panels, fuel tanks, expansion water bottles, bumpers, dashboard, door panels, side trim panels for trunks, door handles, main carpet floor mats, and battery casings.
