SB38CNC-TDR-4A Exhaust Pipe Bender

This model is an IPC controlled fully automatic CNC pipe bending machine, which can automatically bend, automatically feed, and automatically rotate the pipe. The four axes of feeding, rotatingbendingleft-right shifting mold are precisely controlled by Mitsubishi servo motors.

Applicable materials: steel pipes, stainless steel pipes, iron pipes, aluminum pipes, copper pipes, titanium pipes, galvanized pipes, etc.

Especially suitable for the processing of pipe fittings with many spatial angles and high precision requirements. Such as: production of automobile fuel pipes, air conditioning pipes, headrests, motorcycles and bicycle frames etc.

Standard tools: bending die, clamping die, pressure die.

bending tools

Optional tools: wiper die, mandrel to effectively control the deformation and wrinkling of the processed pipe during bending. Bending without a mandrel is relatively simple. Generally, a tube with a small diameter, such as a 6-8 mm tube, which has more support on its own, it is not necessary to use a mandrel, and the ellipticity is within 5% of the tube’s outer diameter. Some galvanized pipes and iron pipes with large bending radius and thick walls can also be made without mandrels. However, for thin-walled pipes with small bending radius and large diameter, a mandrel should be used to support the inner wall of the pipe to prevent its cross-section from turning oval and wrinkling at the inner side.


Tools material: mainly selected according to the pipe material and the bending difficulty. Common materials are 45#, Cr12, industrial nylon, 42MrMo, copper. Generally, we use 42MrMo,it’s vacuum quenched, the surface is nitrided, and the hardness of the mold surface is not less than HRC55 to ensure the wear resistance of the mold.

Tools size: customized according to the bending radius of different pipes.
