company news about Application of hot plate welding and ultrasonic welding on automotive interior parts

Hot plate welding and ultrasonic welding are still used in automotive interior parts. Automotive plastic fuel tanks, batteries, taillights, glove boxes, etc. are commonly used in hot plate processes, and automotive interior parts such as door panels, columns, and instrument panels are commonly used for ultrasonics. Process welding. Learn about welding of automotive interior parts together.

Plastics are gradually replacing heavy weight due to their light weight, decorative and hand-feeling, and their low metal density, good physical elasticity, chemical resistance, good colorability, good processing performance, large design freedom and environmental protection. Metal materials, the application of plastics in the automotive process in our eyes is inseparable from welding technology. The level of plastic welding technology is one of the indicators to measure the development level of new materials for automobile production. The automobile industry includes various plastic welding methods such as hot gas welding, hot tool welding, electric resistance welding, induction welding, high frequency welding, laser welding, vibration welding, ultrasonic welding, etc. The content relates to the latest plastic welding methods of various welding methods. Widely used in connecting various components such as car dashboard, bumper, intake manifold, fuel tank, hydraulic tank, battery slot, lampshade, front and rear lamp components.

Welding technology in application

The plastics used in the automotive industry are: a thermosetting plastic that can be used for ordinary baking operations in production; and a thermoplastic that is easy to process quickly. Commonly used in the automotive industry, the plastics application situation is: polyurethane 19.6%, thermosetting composite 10.4%, polyvinyl chloride 12.2%, ABS8% and so on. The connection of plastics is a key part of its wide application. Plastic welding is economical, simple, fast and reliable. Plastics suitable for mass production in the automotive industry are increasingly favored by the automotive industry. The development level of the principle of plastic welding technology has become an indicator to measure the level of plastic technology applied in the automobile production industry to a certain extent.

Automotive interior parts hot plate welding

In terms of production, manufacturers generally use a hot plate welding machine to control the movement of the hot plate welding mold direction, while using a hydraulic drive or servo motor to drive. The advantage is that in the production process, it can be used for any welding of workpieces with different requirements, so that the welding strength of the finished workpiece can reach the relevant standards, and the missing plastic can be compensated later. It is also possible to adjust the welding procedure according to different production needs. The equipment can maintain stability during the welding process and ensure that the welding degree after the workpiece is processed meets the standard. These welding equipments have long been used in the production of the automotive industry. With the rapid development of the automotive industry, the requirements of the automotive industry for the production of parts, parts and time of use are increasing, and the performance requirements of their processing equipment are increasing. strict. Under normal circumstances, the performance of the equipment directly affects the quality of the welded parts. In the industrial production process, it is necessary for the designer to apply the equipment and select the driving method of the equipment according to the relevant standards for the parts to be produced. In the welding process, the accidental deformation of the parts after heating is the most important problem. In addition, in the industrial welding process, it is necessary to distinguish the polarity and non-polarity of the welding plastic in order to select the application of ultrasonic welding. Laser welding, these two welding techniques have significantly more advantages than hot plate welding technology. At present, most of the plastic fuel tanks, batteries, taillights, glove boxes and other parts of domestic automobiles are applied with welding technology.

Ultrasonic welding of automotive interior parts

At present, the technical development of welding of components such as B5 door panels, columns, and instrument panels is still at the initial technical level, and there are still many problems in the application process. Ultrasonic welding technology has the incomparable advantages of other welding technologies. It was applied to the relevant production of the automotive industry in the 20th century. The application of ultrasonic welding technology is conducive to the goal of shortening production time and increasing cost-effectiveness. At present, the types of ultrasonic welding can be roughly divided into single rivet welding, double rivet welding and spot welding. Each technology is constantly being applied and improved in the industry with its differences. Inferior solder joints are generally not produced when spot welding is used. Furthermore, a single rivet welding that controls the welding pressure is required to ensure that the solder after melting does not affect the soldering fastness. When using high-strength double-welding welding, there is a risk of affecting the surface quality due to the large plastic width of the welding head. Practical experience has shown that the most appropriate welding method can be selected in the production process to ensure the achievement of the established target of the relevant workpiece.

Plastic welding principle and plastic process

Plastics are synthetic or natural polymer compounds as the basic component, which can be plasticized under certain conditions to meet the requirements of the process, so that the final shape of the product remains unchanged. In order to effectively and rationally use energy and reduce the cost of automobile manufacturing to a certain extent, different types of car interior parts can use common plastic materials, which is the most economical in terms of cost, reducing waste, saving resources, and making resources available. The rate has been greatly improved. Plastic materials are widely favored for their light weight and good processing performance. The development of plastic technology has injected color into the life of the automotive industry. Making lean car decorations gives you a refreshing feeling. Today, vigorously promoting environmental protection, the emergence and development of plastic technology can be described as a natural trend. After the plastic crafts are discarded, they can be recycled and reused, becoming a recycling resource, and can expect to meet the quantitative processing standards, so that people can enjoy the plastic process belt. At the same time, it has made a contribution to environmental protection and deepened the awareness of environmental responsibility.
