Embodiment 1

[0020] A method for manufacturing a guitar bag, comprising the steps of:

[0021] The first step is to make the inner box body of the luggage: use polycarbonate to form the inner box skeleton of the set size and specification through high-temperature processing of the injection mold, and flock the inner surface of the inner box skeleton, and then sew it to obtain the inner box body of the luggage;

[0022] The second step is to make the outer box body of the luggage: use EVC to form the outer box frame of the set size and specification through high-temperature processing of the injection mold, and use glue to cover the outer surface of the outer box frame with fabric, and then sew it to obtain the outer box body of the luggage ;

[0023] The third step, the assembly of the inner box of the luggage and the outer box of the luggage: put the inner box of the luggage into the outer box of the luggage, and use glue to bond the outer surface of the inner box of the luggage to the in...

Embodiment 2

[0034] Compared with Embodiment 1, the difference of Embodiment 2 is that in the second step, the edge of the outer box is provided with an aluminum frame and a combination lock, and the closing or opening of the guitar case is completed by the combination lock, which is very convenient to use.

Embodiment 3

[0036] Compared with Embodiment 1, the difference of Embodiment 3 is that in the first step, the inner surface of the inner box skeleton is planted with viscose fluff by adhesive.

Abstract

The invention discloses a method for making a guitar case. The method includes the following steps that firstly, an inner bag box body is made, expandable polystyrenes are utilized and formed into aninner box framework with set dimension specifications by an injection mold through high temperature processing, flocking is conducted on the inner surface of the inner box framework, and then the inner bag box body is obtained through stitching forming; secondly, an outer bag box body is made, ethyl vinyl carbinol (EVC) is utilized and formed into an outer box framework with set dimension specifications by the injection mold through high temperature processing, fabrics are attached to the outer surface of the outer box framework with glue, and then the outer bag box body is obtained through stitching forming; and thirdly, the inner bag box body and the outer bag box body are assembled, the inner bag box body is placed in the outer bag box body, the glue is utilized to bond the outer surface of the inner bag box body and the inner surface of the outer bag box body, and a guitar case finished product is obtained. The manufactured guitar case is light, convenient to carry out, good in quality and long in service life, and can protect the guitar reliably.
