The quality of a pair of shoes, workmanship can reflect a better quality, and the value of this shoe depends on the prospect of this manufacturer. It is subdivided into cutting, manual work, sewing machine (thread), manganese shoes, hammering, glue brushing, priming, processing and packaging. Among them, the injection shoes are directly poured by assembly line, and there are no two processes of brushing glue and dripping bottom. 1, material cutting, as I said before, the principle of material selection is that the toe cap is the best material, and the toe cap can't have skin trauma, dumbfounded, etc. , followed by outside help, inside help, and some humble small positions. 2. Handwork, such as whether the hem is round or square, whether the two shoes are of the same size in the same position, whether the buttons are consistent, whether the inside is clean, whether the buyer's hands are stained, whether the zipper of the zipper shoes is installed smoothly and whether it is pulled smoothly. Whether the inside is smooth, whether there is a bump in the shoes, and so on. 3. Stitching is the process that can best reflect the work of shoes. The normal line margin of shoes is 1MM~ 1.5mm, except for casual shoes. Then the edge of the shoe is too big, too small, the car is rotten and the curve is not smooth. Needle spacing 1 cm, 4.5~5.5 stitches are normal, too thin and too dense are all quality problems. Men's dress shoes are generally not allowed to wear wire or re-sew, let alone wear wire. No matter where the finished shoes leave thread, they are all poor quality. There is a phenomenon that the shoe mouth is cut, there is no car inside, and there is no pinhole left. The quality is very poor. 4. Manganese shoes are a process of shaping the upper after putting on the shoe last. Make sure that the toes are the same length, the toes are straight, the heels are the same height, the heels are the same height, the toes are the same size, and the slope is smooth. 5, over-hammering, the key is that the adhesion between the upper and the sole should be smooth, and there should be no unevenness or blistering, especially the toe and heel. Some low-end women's shoes are the worst. 6. There are two kinds of brush glue, top brush glue and bottom brush glue. Some of the uppers have serious glue spillage. Shopkeepers selling PU sandals should know that if there is no sandal stock for two years, they will definitely open the top glue, so they can only throw it in the trash can. It is also a quality problem that the foot overflows the upper. The most annoying problem is that the glue will open when the foot is not in place. Shopkeepers found that it was best not to take the goods or take less shoes with rubber mouth exceeding 3CM. If it is only a pair of quality problems, it is easy to say that many factories open glue because of improper use of treated water or quality problems of glue during operation, as well as omissions in processing procedures. After all, all the people who wear shoes are worried about their shoes being broken and their soles falling off. 7. The most important thing for shoes is packaging, and selling photos depends on packaging. Cleanliness, the glue on the upper is not cleaned, and the marking line is not cleaned, all of which are the quality problems of the shoes. High-grade women's shoes require a pair of spare leather. Nails in shoes are a very serious problem. When you try it on, you must check it carefully first. Abroad, some companies will be fined $50,000 for having nails in their shoes. Stuffing paper is the most critical link, such as putting chopsticks and sets of boards. Shoes should be sold at a good price and packaging is very important, such as handbags and shoe boxes.
