发明名称 Method to fabricate a seamless tube
摘要 The present disclosure relates to a process for making a seamless tube from a liquid. A mandrel may be provided having a longitudinal axis, an outer surface and a length. A liquid material may be applied to the outer surface of the mandrel by one or more doctor blades, spaced apart from the mandrel outer surface and inclined at an angle alpha with respect to the mandrel longitudinal axis, which may be moved along the longitudinal axis of the mandrel while rotating the mandrel around its longitudinal axis. One or a plurality of fingers may overly the mandrel and be positioned upstream of the one or more of blades, relative to the direction of movement of the blades along the longitudinal axis of the mandrel. The liquid material may then be converted to form a seamless tube.
