Introduction 1. Cutting of auxiliary materials: The cutting process is also called blanking, cutting and cutting. It refers to the process of cutting lining materials into various shapes according to the requirements of technological processing, including fabric cutting and raw material cutting. Commonly used upper materials include natural upper leather, substitute upper leather and textile fiber materials. Second, the processing of vamp parts: After the vamp material is cut, it can only be sewn after a series of processing such as plate, painting, lining and folding. Third, the production of the vamp: After the vamp parts are processed, the vamp can be inlaid and sewn, and the vamp parts can be decorated and beautified, and finally a pair of perfect vamps can be made. Fourth, the cutting of the bottom material: the cutting of the bottom material is similar to that of the upper, because the sole part is simpler than the upper part, and the sole material is thicker, and most of them are cut by machine, and then transferred to the next process after processing and molding. 5. Processing and molding of bottom parts: After cutting, the bottom parts are generally assembled after processing and molding. Machining and molding can standardize and standardize parts, which is convenient for the operation of subsequent processes. The processing and molding methods are different according to different requirements, mainly including plate, pressing, fitting assembly and other technological processes. Sixth, the molding of the upper: the molding of the upper refers to the process of molding the upper into the main shoe type. Upper molding is also the basic part of the combination of upper and sole. In the bonding process, the upper cannot be formed without the last and insole. Usually, the shoe last is stretched, the upper is put on the shoe last and bonded to the insole. Through the molding of the vamp, a cavity for accommodating human feet can be formed between the insole and the vamp. Seven, the combination of soles: the combination of soles refers to the process of combining the upper with the insole and then with the outsole. The combination of vamp and insole is the basic combination. A cavity for receiving a foot may be formed. The combination of upper and sole is the structural combination after the basic combination, thus forming a complete pair of shoes. There are many methods of structural combination, which can be divided into several different production processes according to different combination methods. In addition to the gluing process, there are joint process, vulcanization process, molding process and injection molding process. 8. Finishing, inspection and packaging of finished shoes: In the production of leather shoes, the finishing process of finished shoes began to shift from shoe last. For glued craft shoes with molded rubber soles, they can be painted directly after the last shoe, while for assembling soles, the heels should be assembled after the last shoe and then transferred to the painting process.
