The diagram illustrates the process of producing a pencil, from growing wood to the final packaged product. Overall, the diagram involves several stages, initiating with wood planting and ending with the finishing product.
Initially, wood are planted for a period of around four months before being replanted. They grow after three, after which they are selectively thinned to ensure optimal growth. Following a total growth period of around fourteen years, the trees are pruned and transported to a processing facility, where they are converted into thin wood.
Subsequently, these slats undergo treatment and are left to dry for roughly sixty days. Grooves are then precisely carved into the slats to insert the graphite core. Once the graphite is inserted, an additional slat is affixed on top using heat with hard pressed, forming a composite structure. This is subjected to heat and pressure before being cut into single pencil units.
In the final stages, the pencils are painted, sharpened, and embossed with branding. They are then systematically packaged, rendering them ready for commercial distribution.
