FABRICATION


Shoemaking as such, had been doing so since the early historical craft. And although in Roman times there was a huge amount of shoes, the processes were handmade, therefore the mass production process arguably not appear until the time of the Industrial Revolution.
In both procedures, although differently, you follow a few basic steps:
Selection of skins or materials.
Cortado. According to the outline to be acquired parts.
Lowered. Recess parts, mainly skin.
Trim (also called aparado or stitching). Sewing cut parts.
Mounted (also called focus). One mold being used which serves as a model standing fit when the shoe parts (toe or shovel heel, sole, etc.)
Encajillado. Introduction of shoes in cardboard boxes.
Process craft
The traditional process is essentially a process manual that sophisticated technology is not used. Made in a small family workshop or in a native community, are generally used for high-quality natural materials, also used in some cases chemical and industrial processes of all types to make them.
Industrial Process
Within the various sections of the manufacture of a shoe, as we have seen above, the cut is done in three different ways or methods, the cut manually using a hand tool to cut the skin using a pattern (usually cardboard or sheet steel). Still, there are automatic cutting machines, die cutting, mainly used for cutting the inner lining of the shoe, usually of lower quality leather, falzas or between soles, and leather for the upper, another method is new and modern computerized cutting which uses software for configuration and location of parts of the skin, the order is given as give the print command, only putting points back painting stitches performs cutting with a blade or laser This latter method has advantages over earlier, does not require an investment in dies for each design, you can make cuts in more detail than if it were cut by hand in less time, using fake fur configuration is done in less time and configuration with fewer cycles.
The lining is made with sewing machines similar to those used in the textile industry.
The assembled perhaps the most mechanized in the footwear industry. In fact this section is also called the track, because the shoes are scrolling through some drawers that run on a route of iron (up to the worker) and each worker is becoming part of the work of this section using a machine. The exact process of riding (junction of the skin with the sole of the shoe) is made with a machine called "machine fitted".
There are two methods of putting the shoe sole injection pneumatically to court when the sole is injected separately this is stuck manually by an operator and extended as air, the second method is when the sole is injected directly on the cut a mold, this is called shear injection.
The paper packaging boxes, is also manual. The shoe pairs is introduced in boxes. It will include regulatory labels, bar codes to facilitate the sale in stores, etc.. Several shoe boxes (6, 10, 12, 24 ...) are inserted in a carton to facilitate their transport to the customer.
