Abstract

The invention relates to a method for making shaped plastic tubes that comprises the following steps: a) introducing the tube that is to be shaped into a suitable mould and clamping it in this position; b) circulating hot air, at a temperature of between 100 and 200 degree C, through the tube; b1) inserting one or more movable punches into the tube; and c) applying pressure to the inside of the tube until it reaches the shape of the mould. The invention also relates to the resulting tubes and to the tooling used for carrying out the method. <IMAGE>
