The diagram illustrates the process of leather production. Overall, the process is combination of machine and human labour. The process can be divided into three main stages : preparation, treatment and refinement.
The process begin with the transportation of animal skins from farms and they are classified into many different size. After that, the skins undergo manual trimmed before adding salt. The skins are put on shelves to cure for 30 days.
The process continues with soaking in water for 12 to 24 hours to prepare for hair removal, which carried out by knife. Then, salt and acid are dispensed from two pipes into a rotating drum for 48 hours , preparing for the next stage.
The final stages include colouring and softening by using oil. Afterwards, the skins are dried with a dryer before undergoing a waxing process, which helps to perfect their appearance and sell them.
