11. We often hear the natural skin “breathability” better, so shoes made of natural leather, easier to discharge sweat, keeping the foot dry; fact, “breathability” Good skin is a natural feature, but keep the foot dry and not by the natural leather of the “breathability” come; familiar shoe people should know the shoes are not constituted by a single natural dough in the uppers, any level (including the inside and hard lining, reinforced etc.) and lamination glue, can be a natural skin barrier “breathability” and therefore should actually lining “hygroscopic” role derived; when using shoe lining when inhaled through sweat (moisture), When not used naturally in the natural skin moisture evaporation, thereby maintaining a drying shoes.
12. White glue (LATEX) is temporary in adhesive glue (reusable peel), water infiltration, should be used as a foam applicator, heated dry blazing fast, because add “ammonia” and therefore have a odor; WHITE adding ammonia in order to save longer to make white plastic non-perishable, the smell when in use, but the smell of volatile finished, it means hair is dry.
13. Forming the bottom station of the bonding surfaces are generally open with a groove (commonly known as the window) is to one, reduce outsole weight, two, material representing provinces, three, increase the buckling resistance.
14. After melt aluminum mold after cooling will shrink (metal thermal expansion and contraction principle), commonly known as shrink, cast aluminum lasts for a master model, you need to add pre-shrinkage, so the mother mold will last slightly larger than the original (fertilizer, W), which has been added a master mold shrinkage, we call (shrink last).
15. PU PVC substrates and substrate, respectively, the method of the base station can be identified appearance, such as the case of flowers embossed appearance, you can view the flower pattern is intact, as can be judged complete PU bottom grid; reason ( a) PVC material is thermoplastic materials, require the use of high temperature and high pressure, squeezing into the mold forming, because the relationship between high pressure to squeeze into the mold, the PVC material filled with flower pattern than can reach every corner, you can get after ejection more complete base station, (two) PU material is a material flow state at room temperature, without the use of high temperature and high pressure squeeze molding, casting plaster just like the way the image is made, because without the use of high pressure so precise mold degree can lower tooling costs than provinces, but in the end the process of manufacturing small bubbles will naturally remain in force case corner flower can be found some bubble-shaped gap.
16. Camber lasts errors caused, many factors, such as a shoe last head of Camber, is selected as 8m / m, after its completion shoes become 6m / m, the following error may be: one, after the eye too high, two, thin soles, three, sole is too short, four, free to change the plug Zhuang thickness (thick), five, core long, six, drained filled belly (original setting filled belly), seven, installed Nail heel shift (move forward), eight, outsole material retraction, nine, toe leveling bad (lasting bits).
17. Camber lasts errors caused, many factors, such as a shoe lasts Camber, is selected as 8m / m, after its completion shoes became 10m / m, it is possible for the following errors: one, followed by a low (including day skin is too thin), two, thick soles, three, sole long, four, in the end too soft, five, plug village did not touch the ground, six, did not focus on the core, seven, fill the belly is too thick, eight, knot help pull too much (too small or pattern vamp Alice is too large), nine, with the throat too deep (nail back after deformation), ten, to help end (including skew).
18. To help end molded shoes, the importance is often overlooked in the end; lasting into spending by the Department of shoes uppers made to help shape for the end of the midsole, linked into a container object, vamp and midsole for each form The volume mounted foot space, so vamp and midsole either poor or bad connection, in addition to wearing the shoes will cause the outer (short life), but also cause changes in the volume of space (dressed too loose or too tight, still far below Standard last shape), and prevent harm wear.
19. In the bottom of the container to constitute shoes “bottom”, in order to meet molding operations and shoes with volume standards, in the end it is appropriate to blame a “bottom shape” of course, is “last bottom” as a basis, so the original is a flat plate in the end, processed into the appropriate “bottom shape” called in the bottom shaping, make sure you really need to, that in the end need surgery, but in the end after shaping, must match last bottom, otherwise it will be cause lasting problems.
20. Molding method, there are two: one is to help end molding, a molding for the last entry; leave a lasting molded shoes to help end digital clamp into the last bottom, while the clamp into the last bottom soles lasting bit to be covered, as long as no impact durable, lasting bit width error can be larger, so help end forming shoe uppers sample preparation easier; into the last line of shoes will be forming preformed uppers shoe bag shape and then squeeze the molding into its pouch-shaped upper volume space needs and the volume of shoe fit, but yet there is (and is not anti-) pocket (welt) to successfully squeeze into shoes, so to enter the city last molding method shoes its template (already linked vamp and midsole so regardless of uppers or soles boilerplate template) must be more precise accuracy, making it much more difficult.
21. Shoe last molding method into two types, one for the package Booties style, a style in California;-called bun-style shoes, leather by the Department will be an end to the last table on the last wrap, stitched on the back cover sheet, like (buns), named after its last bottom edge of the whole or part without engaging the suture; California style into the last system of law, and its upper construction and public two kinds, one for the California shoe manufacturing method, leaving only about engaging edge bit of the vamp and midsole stitching left splice become linked in the bottom pocket vamp, after the last entry is molded; one is in the bottom part to (S)-shaped manner into a bag-shaped vamp link method its principles and in the end the system board link (stitched vamp) of California shoes the same, but in the end will be disassembled (-shaped), press the plate on the toe and vamp further localized to the suture toe shoes together, their characteristics and the same package Booties, the Department extended by the same machine material into a bag-shaped vamp made.
22. The uppers, shoe-shaped support a method called molding, molding method, there are two, one is to help end molding, a molding method for the last entry; Others include the lasting fit and molded into the last as the preceding entry last posterior segment lasting package Booties, or posterior segment into the last preceding lasting shoes; like to adhesion France molding shoes guilty lasting shape to the network cable way (to help end after suture knot help located at the bottom) is also an end to help shape; California shoe is molded into the last, S “-shaped structure in the bottom of the sneaker is molded into the last.
23. Then rubber, plastic, EVA, PU, leather and other chemical materials, the surface to be bonded to the first treatment agent (smear); bonding natural leather, the need to be scraped (roughen) the surface of the decorative coating material (paint, leather paddle or wax, etc.), so that adhesive to penetrate the “skin body” (two palm fiber layer), and avoid as surface coatings peel, followed by adverse effects; natural leather and cotton fabric of engagement, without the use of processing agent.
24. Glue the bottom with a stalemate agents and distribution noodle with Glue; equipped with a permanent end to the stalemate agent, firmly affixed to one that does not allow tear, such as the general powers of the yellow plastic glue, paste syrup, PU glue, etc. ; noodle with the stalemate for temporary agents, such as white glue (LATEX), petrol rubber (rubber paste) …… etc. noodle using temporary glue because it is used mostly for range, folding, posted in the other, The equivalent and fit it after the work must then be sewn by sewing, so no strong adhesion, moreover also convenient fold or mislabeled error correction.
