1. Reasons for poor glue in the process of making shoes

(1)the drying temperature is too low or too high, should be maintained at 55 ° C -65 ° C.

(2) the drying time is not enough to paste, usually 5-8 minutes.

(3) after being glued, it is blown by the wind.

(4) The surface is white mist after being wetted by the glue.

(5) The quality of the adhesive is not good.

(6) the amount of glue is insufficient.


2, sewing shoes

Sewing shoes are separated by slits (with insole), beading (without insole), and slits (machine seams and hand seams).


3, molded shoes

(1) The upper and the inner sole are stretched and shaped on the shoe last, and then converted into a metal crucible, and then placed in a bottom mold cavity equipped with a rubber material, and vulcanized by a high temperature of a molding machine.

(2), the upper and the midsole (canvas) are sewn with a sewing machine, and then directly placed on the metal crucible, and then placed in a bottom mold cavity with a rubber compound and vulcanized at a high temperature by a molding machine.


4, injection shoes

The shoe is made of an injection molding process and is suitable for use in travel shoes. The bottoming process is roughly similar to the molding process.

The combination of the upper and the midsole is similar to that of the set, and is stitched with a sewing machine, and the aluminum crucible is directly applied without stretching.
