From April 13 to 15, 2026, AMR China International Auto Parts Exhibition (Beijing) was grandly opened. As a leading and influential automotive aftermarket industry event in Asia, this exhibition attracted enterprises and professional visitors from all over the world in the fields of auto protection equipment, auto parts and components, intelligent diagnostics, and maintenance chains. As a professional manufacturer focusing on pipe end forming technology, R&D brought its core nozzle rounding solution and a variety of customized pipe fitting cases to the exhibition site. With its hard core technical strength and open industry communication attitude, it has received high attention and recognition from customers and peers at home and abroad.
During the exhibition, Yanrui Lin booth welcomed a number of overseas customers to visit and negotiate. The company's foreign trade team explained the technical parameters, application scenarios and customized solutions of the equipment in detail to overseas customers with professional and efficient services, and conducted in-depth one-on-one communication and demonstration in response to customer production needs and technical questions. Through face-to-face exchanges, overseas customers have given high praise to the accuracy, efficiency and stability of the nozzle rounding equipment of Yanruilin, and some customers have reached a preliminary intention on follow-up cooperation and customization plans.
The rounding of the nozzle is a seemingly insignificant but crucial process in the processing of pipe fittings in the automotive aftermarket. During the production and maintenance of automobile exhaust pipes, mufflers, ternary catalysts and other components, after the pipe is cut, welded or stamped, the pipe mouth often has elliptical deformation, closing, burr, flanging and other problems, which directly affect the sealing and airtightness of the subsequent assembly. The nozzle rounding equipment performs mechanical rounding and sizing of the nozzle by means of multi-roll spinning or mold constraint, so that the nozzle roundness, aperture size and perpendicularity are restored to the design tolerance range, which is the key equipment to ensure the assembly quality of the exhaust system.
For a long time, small and medium-sized maintenance companies have relied on traditional methods such as manual tapping and simple expansion of the head to correct the nozzle, which is not only inefficient, but also difficult to ensure roundness and caliber accuracy, and the consistency of batch operations can not be talked about. With the continuous improvement of assembly accuracy and delivery capacity requirements for exhaust customization, modification and upgrading, and other businesses, specialized rounding equipment is accelerating to replace the traditional manual correction process, and has become a necessary equipment for improving the quality and efficiency of pipe processing.
At this exhibition, Yanruilin focused on demonstrating the core technical capabilities of its nozzle rounding solution. The equipment adopts a highly rigid structure design and hydraulic servo control. The complete circular pressure and feeding stroke can be accurately set and adapted to pipes of different wall thicknesses and materials. For materials such as stainless steel pipes, aluminum-plated pipes, and carbon steel pipes common in the automotive industry, it is equipped with a special mold and process parameter library. The processing object can be switched with one-click call. The processing beat is compact, and the single-piece complete circle takes only seconds to tens of seconds, which can meet the dual requirements of batch repair and customized production.
In the customized pipe fitting case display area, Ruilin displays a variety of exhaust pipe fittings and joint samples processed by the equipment. The roundness of the nozzle is full, the edges are flat, and the audience can visually compare the differences before and after the roundness. Many visitors engaged in exhaust pipe customization and maintenance said that this kind of equipment is exactly the professional equipment that is urgently needed for the transformation and upgrading of the industry - in the past, the method of manual percussion correction was inefficient and inconsistent, and the special round equipment not only greatly improved the processing quality, but also made it possible to batch customization business.
As the vane of the automotive aftermarket, AMR exhibitions have continued to show a trend of "specialization and segmentation" in recent years. With the continuous growth of vehicle ownership and the expansion of segments such as personalized modifications and exhaust system upgrades, the demand for professional pipe fitting processing equipment has risen. Research and development attended this exhibition, and it is precisely the specialized demand of the automotive aftermarket for the nozzle forming and rounding process that extends the company's years of technology accumulation in the pipe end forming field to the auto parts application scenario.
From the feedback of the on-site audience, the customized modification of the exhaust system, the maintenance and replacement of the muffler, the remanufacturing of the ternary catalyst, and other subdivisions have put forward clear requirements for the quality of the nozzle forming; the more stringent emission detection in some areas has also prompted maintenance companies to pay more attention to the sealing and consistency of the exhaust pipeline. Together, these changes point to a clear signal: specialized tube-end forming equipment is becoming a rigid demand in the wave of post-automotive market upgrades.
At the exhibition site, the research and development technical team also conducted a number of technical exchanges with peers and end users around the theme of "common quality problems and process optimization of nozzle forming". From the influence of the pipe cutting method on the nozzle deformation, to the selection and wear control of the round die, to the relationship between the processing accuracy and the assembly seal, the team unreservedly shared the experience gained in the engineering practice, won the unanimous praise of the audience on the spot, and further highlighted the industry attitude of Yanrui Lin opening up and win-win.
During the three-day exhibition, Ruilin Booth received hundreds of professional visitors and customers at home and abroad, and reached cooperation intentions with 13 companies, covering auto parts manufacturing, exhaust system customization, equipment agency and other fields. A number of companies on-site agreed to conduct field visits to the Lindongtai factory in Yanrui in the near future to further discuss equipment procurement and long-term cooperation.
From the perspective of the structure of the cooperation intention, the demand presents diversified characteristics: there are small and medium-sized processing workshops equipped with complete circular single machines for the exhaust customization business, auto parts manufacturing enterprises that plan to introduce multi-process combinations of shrinkage, expansion and pier head, and channel partners who hope to agent R&D products and serve the local aftermarket. According to the production capacity scale and process starting point of different customers, the sales engineer gave the suggestion of phased equipment configuration and input-output estimation on site to help customers take the first step of upgrading with reasonable input.
In fact, the nozzle rounding solution exhibited at this exhibition is only one member of the DN12 to DN390 full-specification pipe end forming equipment matrix. The company's product line covers single-station, double-station, horizontal, vertical, five-row, transmission and other models, and can complete a variety of processes such as shrinkage, expansion, pier head, rounding, flanging, etc. Products are exported to Europe, the Americas, Southeast Asia and other countries and regions, serving more than 1,000 customers worldwide. The deep technical background and rich industry application experience are precisely the reason why R&D is able to respond quickly to the needs of the auto parts industry and win the trust of customers.
The exhibition ended and the cooperation started. Yan Ruilin thanks every customer and friend who came to the booth, and looks forward to working with more automotive aftermarket partners to jointly promote the upgrading of the processing capacity of the industry with more professional pipe end forming and rounding technology. Customers at home and abroad are welcome to contact us at any time to obtain the selection plan and technical support. We also sincerely invite you to visit the Dongtai factory in Yancheng, Jiangsu Province for on-site inspection and guidance.
