New Energy Vehicles: Plastics Promote Lightweight & Laser Lifting Process

       New energy vehicles are the development trend of the automobile industry. Statistics from relevant institutions show that the number of new energy vehicles in the Chinese market currently exceeds 1 million, and it is expected to exceed 5 million in 2020. The prospect of new energy vehicles will be very broad. With its performance advantages, plastic materials have played an important role in promoting the production of lightweight and special parts for new energy vehicles. Plastic laser welding has improved the process, and data shows that the automotive industry has become one of the fastest growing areas of plastic demand.

Lightweight is an important factor restricting the development of new energy vehicles. Affected by the power system and market orientation, the development of lightweight new energy vehicles has always attracted much attention. However, with the application of high-performance plastic materials in automobiles, the lightweight problem of new energy vehicles has been alleviated to a certain extent. It is understood that the demand for resins such as nylon, polypropylene, polyurethane and other engineering plastics for new energy vehicles is very large, accounting for more than 30% of the total resin market demand; the demand for polyvinyl butyral accounts for about more than 85% of the total demand. Plastic materials can be seen on many important parts such as bumpers, fuel tanks, body panels and chassis, engine intake manifolds, and clutch actuation systems.

       Compared with traditional alloy materials, plastic components have unparalleled advantages. Plastic products will help reduce the weight of the car. The data shows that for every 10% reduction in the weight of the car, the fuel economy can be improved by 5%, so new energy vehicles using plastic products can run farther.

Plastic products can also reduce the production cost of car companies. A simple injection-molded plastic part can perform the function of welding many metal parts together. Plastic can be molded into more complex shapes than steel assemblies, which can reduce the integration process. Number of parts used.

In addition, the elastic deformation characteristics of plastic products can absorb a large amount of collision energy, have a greater buffering effect on strong impacts, and play a good role in protecting vehicles and passengers; plastics have strong corrosion resistance, local damage will not corrode, while steel Once the paint surface is damaged or the pre-corrosion is not done well, it is easy to rust and corrode, which not only affects the beauty of the car body but also poses a safety hazard; plastics can be added according to the composition of plastics by adding different fillers, plasticizers and The hardener can make plastics with the required properties, and modify the mechanical strength and processing and molding properties of the plastics to meet the application requirements of different parts on the car. It can be said that plastics have contributed to the rapid development of new energy vehicles, and at the same time, the rapid development of new energy vehicles has opened up a broad market for plastics.

Facing the world's largest plastic demand market, my country's plastic laser welding technology market prospects are also very impressive. Just like Guangdong Shunde Huazhuo Machinery Technology Co., Ltd. has long been aware of this huge market, and has become the leader of plastic laser welding technology in my country in just three years.

Plastic laser welding technology belongs to non-contact welding technology. Compared with other welding methods, it has the advantages of non-contact, airtight, watertight, fast welding speed, high precision, high weld strength, no flash, no residue, no vibration, minimal thermal stress, easy control, and good flexibility. , good adaptability and many other advantages. The connection of automotive plastics is a key link in its wide application. The level of plastic welding technology is one of the signs to measure the level of automotive production technology and the development of new materials.
