Footwear manufacturing has not changed significantly over time. It is still done by hand using small-scale, mechanical equipment and rudimentary techniques.
6. Mounting: The mold is selected in accordance with the model number. The bottom is made stationary using nails and cement. This is done manually and a special machine is used to press the pieces so that the shoe is formed and shaped properly. Toes and heels are mounted. Then a setting process is conducted to ensure that the shoe fits perfectly to the mold.
7. Attaching the sole by the traditional bonding process: The soles are purchased pre-made. First the sole is marked then punched where the upper is going to be glued. The punching is done by a special machine so glue will saturate better into the sole. Next, the upper is glued to the sole. The temperature is increased for the gluing in a special machine that presses the sole for 30 seconds. Finally, the mold is removed.
8. Finishing: The insole is glued into the shoe, the edges of the soles and linings of the shoe are painted, and seams and lining are washed with a special soap to remove stains and residues from the production process.
9. Dying: This is done in order to make the color uniform. The athletic shoe is then retouched with polish to give it a shine. This is performed with rotating brushes.
10. Packaging: The model number is printed on and the product is packaged in cardboard boxes.
11. Warehousing of finished products: Once packaged, the finished athletic shoes are shelved according to the style and product number.
For connecting the sole to the upper of the shoe, there are different processes such as gluing and sewing. For gluing, polyurethane adhesives are increasingly being used because they provide durability to the bond of the sole to the shoe.
