This series of expanding machines have been designed and built to expand both, tubes and hairpins with the same machine set-up, made from copper and stainless steel of different diameters and wall thicknesses, handled by seven brushless motors with NC.
To allow this, the expanding rods are entirely embedded in a fully wrapped anti-friction guiding system, that controls their forward & backward movements during the entire expanding process.
This unique solution, while permitting a high expansion speed, considerable working power, easy switch over between the push and the pull systems, immediate pitch change, guarantees the integrity of the expansion rods, avoiding distortion and stress during the process.
