Title:
METHOD FOR MANUFACTURING WELDED MOLDING, WELDED MOLDING, AND PIPE
Document Type and Number:
WIPO Patent Application WO/2021/010436
Kind Code:
A1
Abstract:
This method is for manufacturing a welded molding formed by using liquid crystal polyester as a material, the method comprising: a step for heating a first projection of a first member formed by using a liquid crystal polyester as a material and a second projection of a second member formed by using a liquid crystal polyester as a material, to a temperature equal to or higher than the flowing start temperatures of the respective liquid crystal polyesters; and a step for bringing the first and second projections into contact with each other and vibrating and welding the first and second projections while pressing the projections in directions bringing the two toward each other relatively.
