The diagram illustrates how a pencil is produced through a process.
Overall, the linear process comprises 11 stages, commencing with planting trees to make pencils and culminating with the painting, sharpening, and stamping of final products.
To begin with, trees to make pencils are planted and then these trees are replanted in a container after 4 months. After 3 years, the resulting trees are thinned and then transformed into raw materials for making the pencils after 14 years. As the next step, the trees are cut using thin slats and then treated to become boards. Following the two-month mark, the pieces are glued, the grooves are shaped, and black lead is processed. Then, these are treated in a new slat like a sandwich, followed by hard-pressing with heat. As the final stages of pencil production, the pieces are cut again and then painted, sharpened, and stamped, resulting in the final smooth products.
