Technical Field

The invention relates to the technical field of guitar cases, in particular to a manufacturing method of a guitar case.

Background

Guitars are often considered the primary musical instrument in pop, rock, blues, folk songs, Buddhism. In the field of classical music, guitars often perform in solo or duet style; of course, in indoor music and orchestral music, the guitar also plays a considerable companying role. Since guitars are a great deal of weight in the field of music, the amount of guitars used is large, and the amount of guitar cases and bags to be used increases. However, the weight of the guitar case and bag that has now on the market is heavy, goes out to carry inconveniently, and life is low, and the reliability of protection guitar is relatively poor, can not satisfy guitar user's demand.
