Recently, Jiangsu Yanruilin Precision Machinery Co., Ltd. has completed the full delivery of the tube end forming machine YRL-380, custom-developed for the American precision manufacturing company BMS Aerospace. From technical coordination and sample verification to the shipment of equipment and molds, the project took about six months and concluded with all indicators meeting the standards and receiving high recognition from the client, becoming a typical example of Yanruilin's non-standard customized practice in the field of precision aerospace component forming.

Customer Background:Forty years of experience in precision aviation manufacturing
BMS Aerospace was established in 1981 and is headquartered in Connecticut, USA. It is a diversified precision manufacturing company focused on precision-formed metal components for the military and civil aviation sectors. The company has accumulated extensive technical experience in the maintenance and manufacturing of aircraft engine and airframe components, with customers including leading global gas turbine manufacturers and auxiliary power unit (APU) manufacturers, specializing in the production of various highly complex engine parts.
In terms of processing capabilities, BMS possesses comprehensive technologies including component manufacturing, metal spinning, hydraulic forming, and stamping, offering customers a one-stop solution from customized metal processing to surface treatment, and ensuring rapid delivery from prototype trials to mass production. Precisely because of the long-term use of spinning processes, customers’ requirements for forming accuracy and consistency are much higher than in typical pipe processing scenarios.
Origin of the demand:Spinning process reaches accuracy ceiling
In October 2025, BMS noticed Yanruilin's non-standard customized tube end forming machine through the Alibaba platform and immediately put forward specific technical requirements. This project requires high-precision forming of components, which is technically very challenging—in the period before contacting Yanruilin, BMS had already engaged with several suppliers, none of whom could meet their stringent requirements.
The customer's original tube-end forming equipment mainly used the spinning process. Faced with this order, which requires high precision and strict forming stability, the spinning equipment cannot achieve the specified forming accuracy. This bottleneck has prompted BMS to seek new technical solutions.
After receiving the inquiry, Yanrui Lin quickly organized the technical team for a special discussion and asked the customer to send the physical parts to the company for in-depth analysis and measurement. After a comprehensive evaluation, the tube-end forming machine YRL-380, customized for BMS requirements, was confirmed to fully meet the customer's technical requirements.

Sample Verification:Multiple rounds of inspection until all pass
In January 2026, Yanrui Lin completed the equipment manufacturing as planned and produced the first batch of samples, a total of 12 sets. To strictly verify product quality, the samples were simultaneously sent to the client and a domestic third-party testing organization—Shanghai Liangjiang Testing Equipment Co., Ltd.—for independent testing.
According to the testing feedback, the Yanrui Lin technical team continuously carried out fine adjustments to the molds and sent re-samples for inspection. After multiple rounds of repeated verification, all indicators of the final sample met the standards, receiving high recognition from the client.
In March 2026, the company completed the equipment manufacturing as planned and arranged the shipment of the equipment and the first nine sets of molds; in April 2026, the remaining three sets of molds were shipped. With this, all delivery work was successfully completed.
Technical Support:Independent Programming Control System and Remote Debugging
The YRL-380 delivered this time is programmed independently by Yanruilin's own team of electrical engineers for the control system and is equipped with industrial Internet remote debugging functionality, as well as one-button calibration and multiple alarm devices. These designs significantly improve processing accuracy, optimize the debugging service experience, reduce on-site operation thresholds, and effectively extend the service life of the equipment and molds.
For the client, this solution not only addresses the precision issues that cannot be achieved by the spinning process, but also brings more competitive overall usage costs, laying the foundation for deeper cooperation between both parties in the future.
