About TONG DA
TONG DA PRECISION ENTERPRISE CO., LTD. was established in 1989 and has been deeply engaged in the fields of metal tube processing and special-purpose machinery manufacturing for decades.
We specialize in the research, design, manufacturing, and sales of equipment for metal tube sealing, capping, tube end forming, tube cutting, rotary cutting, grooving, beading, as well as various types of custom tube processing machinery.
With years of hands-on manufacturing experience and technical expertise, TONG DA has grown into a professional manufacturer with strengths in both tube processing and machinery development.
Our services include standard machines, customized special-purpose machines, OEM processing, and production process planning. We are committed to providing customers with stable, efficient, and industry-oriented total solutions.
Development History
In its early years, TONG DA mainly focused on steel tube OEM manufacturing and processing, primarily serving the production of bicycle tube components and fan tube components.
As market demand and industrial conditions evolved, TONG DA expanded its business based on its strong foundation in metal tube manufacturing and established two core divisions:
● Tube Machinery and Special-Purpose Machine Design & Manufacturing Division
● Special Tube Components and Metal Hardware OEM Processing Division
This development has enabled TONG DA not only to build strong machinery design capabilities, but also to apply practical processing experience to better understand customer requirements in terms of materials, dimensions, tolerances, production efficiency, and product consistency.
As a result, we are able to provide solutions that are more aligned with actual production conditions.
Core Technologies and Equipment Development
Through continuous investment in research and development, TONG DA has successfully developed a range of professional machines for high-quality and high-precision metal tube processing.
