(TONG DA company, TONG DA machinery)

Was founded in 1989, has nearly 30 years have proud tradition, specially in pipe manufacture and special pipe fittings machinery manufacturing sales, highly renowned within the pipe fittings manufacturing (such as furniture, baby stroller, tail gate pole, shock absorbers, air bags, etc.), the company early to iron pipe foundry and iron pipe processing in the production of bicycle fittings and fan pipe foundry is given priority to, because of the change of domestic production, after the company in this case, is in accordance with the production of pipe fittings for many years, set up fitting machinery manufacturing with each machine manufacturing, and special pipes pieces, metal hardware products processing OEM manufacturing sector.

After further development of high-speed pneumatic round tube cutting machine and oil pressure type concave-convex wheel groove machine, applied to high quality pipe fittings, and sold in the market, many users have been affirmed.

After many years of research and development of the plane type oil pressure metal pipe sealing machine (sealing machine, pipe end forming machine, metal pipe sealing machine, tube closing machine), and obtained the patent right, this machine subverted the traditional pipe end processing type, and caused the shock in the market at that time.

Through the accumulation of experience, the company based on the plane type hydraulic metal pipe coating machine as the technical basis, carefully developed the arc type hydraulic metal pipe coating machine and obtained the patent rights of many countries.

We made the first machine for our customer more than 10 years ago, and it is still running today. Since then, we have produced many machines and exported them to more than 20 countries.
