In Tik Tok, you can learn the shoe factory's bottom sticking technology. The warehouse takes the sole board, presses it with a punch press, the assembly line workers brush the glue into the oven, the master pastes the shoe soles out of the oven, the workers put on the shoe last, and after shaping by the setting machine, they enter the oven, and then freeze or air dry, usually air dry. Finally, the machine takes out the shoes, pulls out the last head and sticks it on the outsole.
