Footwear basics confluence of great value-three

First, the basic craft shoes
Shoes general classification: the main injection and cold bonding two categories.
Injection molding is the machine to do shoes, uppers on the last bar in aluminum, generally from the turntable machine directly injected PVC, TPR and other materials, disposable form soles, now there are PU (polyurethane chemical name) Injection (machines and molds with generally not the same injection). Advantages: Because it is machine made, production, Gu low prices. Disadvantages: If the style, change the mold more troublesome, shoes stereotypes difficulties, no cold sticky shoes exquisite workmanship, it is generally suitable for the sole single style orders.
    Cold viscosity is what we normally say hand-made shoes, Italy, Spain brand of shoes that belong to this category. Generally require cold sticky pipeline processing (except cottage), cold sticky soles general by playing the sole responsible for the factories, if they are not the sole molds that require additional mold, generally more than double shoe factory 1w free mold. Approach is to use plastic uppers and soles last after a good shape glued together. Advantages: fine workmanship, made the shoes better. Disadvantages: small daily output, higher prices, more generally suitable for medium-sized factories to scale.
Difference method: the difference between cold sticky and injection shoes the most obvious feature is the sole or heel shoes injection molding edge lines are, it was because the shoes left out of the mold. The piece is cold sticky soles uppers and soles in the adhesive that side, it is not apparent.
    Shoe components: shoes mainly by the uppers, lining (lining), before and after the hot end, before and after the header, in the end (also called end-inch), sole and other components.
     Uppers: leather material generally (LEATHER), or artificial leather, leather material mixed, the best was undoubtedly the first layer of leather, soft texture, elasticity is good, I personally still fine soft sheepskin shoes is absolutely cool. There are many artificial leather, I contacted the most, PU leather, thickness of the wire as a unit, generally 80 wire, good up to 140 wire, suitable for production of monolayer uppers (no longer lining), comfortable to wear, especially South Korea's shoes, generally do so. Today's most popular leather PU leather with eraser, rub the leather, bubble pattern, Crazy Horse pattern, size, pattern, Napa pattern, 18 patterns, and so many lines. As crazy horse leather with leather like texture, and made good results, so now very popular, but the price is high. Eraser is the most classic leather, has been popular for 10 years, and now there are many eraser, wiping out the effect is not the same color with a shallow depth, and the wax used with a great relationship, affordable, but the work is difficult, generally require special eraser to rub a good teacher. Now have simulation cowhide leather, wire thickness of 200 or more, the extraordinarily high prices.shoes manufacturer     Lining and hot at the end: materials are generally leather, PU, ​​PVC, etc., leather uppers are generally equipped with leather lining, comfortable, good heat dissipation, not prone to "athlete's foot." Generally the PU lining a lot better than PVC, but expensive!
     Shoe soles is an important part of the end of a PU, TPR bottom, PVC bottom, bottom composition. PU at the end of the advantage of light weight, soft, feel good. Middle East and Europe are customers like PU material of the sole, but expensive (PU recent price rise of terror, a substantial increase in cost, but the shoes prices do not rise, so many factories difficult), now with polyurethane injection ( PU INJECTION, because of the machine to do production, cost reduction, so it is very popular. TPR soles moderate weight, a certain softness, but the price is cheaper than the PU, and there is no smell. PVC soles cheapest price, are generally There is a factory direct injection, but also useful for cold bonding soles PVC material, the texture can be pre-plastic adjustable, hard to soft, but how many PVC soles are a little odor, because it is a plastic material, if mixed plastic with a good oil, then taste is very light, but if you go back to the oil, it tastes pungent, make it difficult to accept, in fact, this depends entirely on the credibility of the plant.shoes factoryIn the end only the mat in the soles and uppers in the middle of that layer, a single material, not much to say here.
Baotou is actually a layer of cardboard, in millimeters, the Taiwan side header produced good quality, 1.7mm header is already very good for him. Mainly used in the toe and heel, to make shoes look angular, played the role of reinforcement shoes.women shoes manufacturer
