The provided diagram illustrates a process in which pencils are manufactured.
Overall, there are a total of 12 steps involved, beginning with the cultivation and harvesting of trees and culminating in the creation of finished products.
In the first place, trees are planted with seedlings, which often takes place in 4 months.Once the plants are replanted, they become mature and the next 3 years, they completely grow up and cut into thin shapes.The fourth step is harvesting, which occurs a long period of 14 years.
Once orginal timbers are available, they undergo the following processes.When raw materials are ready, they are cut into slices by thin slats before treating in the creation of timbers.After 60 days, the timbers are produced, where they mould the grooves and glue and black lead are applied.Subsequently, double new slats are formed as a sandwich-like structure and then they are hard-pressed using heat.After that, they are cut into long sticks.Those sticks are then made to form pencils, which are painted, sharpened and stamped.Ultimately, the products serve as the material for manufacturing pencil boxes, which can be used by consumers.
