Mechanical processing techniques hit their limits with thinwalled structures (under 0,5mm). Electroplating offers a simple alternative production process for that problem.
A pipe is crafted through the exact made to measure stripping on a preproduced core. Complex structures are possible here because the core is only processed from the outside. Depending on requirements several corematerials can be used. Those can be either chemically dissolved or deformed.
Copper, nickel or a combination of both are eligible for this use. Applicabilities are for example waveguides, bushings, heat conductors or thin walled bushes for geology.
