The diagram illustrates the process of manufacturing a lead pencil.
Overall, the process consists of the twelve stages involved in the production of a pencil. It begins with planting saplings and concludes with packaging pencils before they are ready for use.
To start, saplings are replanted in the new soil after 4 months of development to be treated under better conditions. Once they have grown for 4 years , many of the trees are chopped down thinning the density of the area. As the remained trees become adequately high in the next 14 years, they are cut down and transported to the factory to be manufactured. Here, they undergo the sawing process to convert them into thin slats. These slats are then treated and kept in the proper condition for the following 2 months to be utilised more efficiently later.
Following this, their surfaces are grooved to glue with black leads. Next, another same-shaped slat is placed over it to make a sandwich form, and together they are hard-pressed and heated in order to stick them to each other. Once they acquire the single matter, they are separated into pieces. Each pencil is subsequently sharpened, polished colourfully and imprinted with the branding during the stamping sequence. Finally, they can be ready for packing and distributing them to the public.
