Method of manufacturing a heat-resistant resinous tube

A method of manufacturing and mass-producing a seamless heat-resistant resinous tube with a uniform tube wall thickness and circumference, which includes the steps of coating the precursor solution (3) of a tube material to the surface of a core (1) at a thickness greater than the tube wall thicknes...

Beschreibung
Zusammenfassung:	A method of manufacturing and mass-producing a seamless heat-resistant resinous tube with a uniform tube wall thickness and circumference, which includes the steps of coating the precursor solution (3) of a tube material to the surface of a core (1) at a thickness greater than the tube wall thickness; passing a metallic die (2) having a wider inside diameter than the diameter of the core along the outside of the core by utilizing the resistant force of the precursor solution without restricting the metallic die or the core, thus forming a tube (4) around the core; treating the tube around the core to give it strength as a tube; and separating the tube from the core.
