INTEGRALLY-MOLDED GUITAR AND PRODUCTION PROCESS THEREFOR

WIPO Patent Application WO/2023/020145

A1

The present invention relates to an integrally-molded guitar and a production process therefor. The production process comprises the following successive steps: (1) material wrapping, involving roll wrapping the outer side of an air bag with carbon fiber cloth to preliminarily wrap the air bag into a shape resembling a guitar; (2) introduction into a mold for molding, involving putting the air bag wrapped with the carbon fiber cloth into an integrally molding mold, inflating the air bag after the mold is closed, expanding the air bag to enable the carbon fiber cloth to fully fill the integrally molding mold, and pressurizing and heating the integrally molding mold to tightly cure the carbon fiber cloth to form a guitar main body; and (3) demolding and blanking, involving taking out the guitar main body in the integrally molding mold, removing burrs on the guitar main body, deflating the air bag to reduce the volume, and then taking out same to obtain a complete guitar main body. The steps of the production process are rational; and the guitar main body is made in the integrally molding mold by means of one-step molding, such that the processing precision and flatness of a headstock, a neck and a barrel are ensured, the product quality is enhanced, and the production efficiency is improved.
