ABOUT COMPANY

Yantai Yunde Intelligent Technology Co., Ltd.

Yantai Yunde Intelligent Technology Co., Ltd. is a company specializing in the production of centerless lathes (peeling machines), straightening machines, polishing machines, and other round steel finishing equipment. Our products are used for round steel peeling, precision straightening, and polishing, and are dedicated equipment for the finishing and processing of new-generation slender shafts, bright steel (bright materials), bars, and steel pipes.

The centerless lathes and straightening and polishing machines produced by our company feature simple operation, low noise, and high processing speed. The combination of centerless lathes and straightening and polishing machines forms an automatic production line for peeling and precision straightening of long round metal parts such as slender shafts, bars, rods, discs, and steel pipes, producing high-precision bright metal materials. This is an upgraded alternative to traditional cold drawing and pickling processes, as well as the combination of conventional lathe turning and centerless (rough) grinding.

The company consistently adheres to the work philosophy of "integrity and quality"; we strive to meet the diverse needs of our customers with focused technology, excellent quality, timely delivery, and superior service. The company has a dedicated R&D department and after-sales service team, providing professional solutions based on customer needs and continuously introducing more advanced new products through innovative technologies. In the future, we will, as always, uphold the corporate tenet of "reputation first, attentive service," and establish a new benchmark in the mechanical processing industry.

Development History

Move forward in exploration and grow in challenges

2006-2014
From 2006 to 2014, the initial design team was formed.
Mr. Jiang Yufu graduated from Northeast Heavy Machinery Institute in 1984 (which originated from the Heavy Machinery Department of Harbin Institute of Technology, established in 1958, inheriting a rich legacy of heavy machinery technology). He has been deeply involved in the field of mechanical design and manufacturing for over forty years. In 2006, he was invited to serve as the chief engineer at Yantai Haige Machine Tool Co., Ltd., responsible for the design of two-roll straightening machines. In 2008, he led a team to develop peeling machines, overcoming core technical challenges and obtaining multiple patents. This improved the processing accuracy and production capacity of bar materials, contributing to industry upgrades and promoting the localization of metal finishing equipment, gradually forming the initial core design team.
2006-2014
2015
In 2015, Yantai Yunde Intelligent Technology Co., Ltd. was established.
After the merger of Yantai Haige Machine Tool and Hangjian, the original Haige design, production, customer service, and sales teams, due to differences in development philosophy, independently formed Yantai Yunde Intelligent Technology Co., Ltd. Located in Muping District, Yantai City, the company focuses on the mechanical equipment field, emphasizing precision improvement and fault rate control, and continuously strives for technological advancements.
2015
2018
In 2018, technological upgrades brought the precision to the level of international counterparts.
The technical team overcame technical challenges, achieving stable peeling machine precision of ≤h8 and roughness of ≤1.6μm, and straightened bar surface roughness of ≤0.4μm. The production capacity of both machines increased by over 50%, and the failure rate was significantly reduced, substantially lowering customer maintenance costs.
2018
2020
In 2020, the product gained international recognition.
Large enterprises in India and Taiwan recognized the quality of Yunde Intelligent Equipment, whose performance is comparable to international competitors. They began ordering peeling machines, straightening machines, and polishing machines, and have continued to place new orders every year since.
2020
2025
In 2025, a foreign trade department was established to expand globally.
After ten years of development, Yantai Yunde Intelligent has accumulated nearly a thousand customers at home and abroad. Its technology has made a qualitative leap and reached a leading level in China, giving it strong competitiveness in the international market. Therefore, a foreign trade department was established to fully explore the global market and provide overseas and domestic customers with highly cost-effective equipment and supporting services.
