Abstract

PURPOSE: To execute painting which is satisfactory in its adhesive property without performing a special surface treatment, to a pipe whose length is not limited, by continuously performing the painting to the inside surface of an extruding pipe, when extruding the pipe.
CONSTITUTION: Al l which has been fed into a die block 2 passes through an air gap between an extruding die 3 and a hollow mandrel 4 of its inside by extruding pressure of a ram, and an Al pipe 5 is extruded. A painting spray gun 6 is inserted from the rear opened part of the mandrel 4, and its tip is positioned in front of the die 3. In this state, a painting material 7 is jetted to its inside from the spray gun 6, extruding the pipe 5, painting 8 is performed to the inside surface of the pipe 5. In this regard, a pipe which has just been extruded from the die 4 is usually high in its temperature, therefore,when it is painted as it is, it is changed in its quality depending on a painting material, and accordingly, as soon as the pipe 5 is extruded, it is cooled to a suitable temperature as necessary.
