Tube Bending – Precise Forming for Efficient Liquid Cooling
Tube bending is a key manufacturing step in producing modern liquid coolers and heat sinks. With precise bending technologies, copper, aluminum, and stainless-steel tubes can be shaped exactly to the required geometry, enabling compact, high-performance, and custom-configured cooling structures.

Whether for prototypes, small batches, or series production – tube bending enables flexible, cost-efficient, and reproducible implementation of thermal systems in power electronics, e-mobility, and industrial cooling technology. In the bending process, a straight tube is formed into the desired shape using a CNC bending machine. Depending on the material, the tube is cold- or hot-formed to avoid deformation or thinning.
The use of precise mandrel and roll bending machines allows for tight bending radii, consistent wall thicknesses, and high repeat accuracy.
