In a year, the Crayola company produces nearly 3 billion colorful wax sticks. She helps the company supply the world with more and more crayons. Crayola produces its crayons in large batches. The crayons harden as they cool. A robotic arm picks them up. A conveyor belt moves them to a labeling machine. It wraps a paper label twice around each stick. The machine puts them into boxes. Next, an inspector looks at each crayon and picks out any that are chipped or broken.
Those crayons will be melted into another batch. Meanwhile, the good crayons are scooped up by a worker. They are stacked into a collator. The machine places one crayon of each color into boxes. Now the crayons are ready to be sent to stores.
Crayola has been making boxes of crayons for years. The first set had eight colors. Today, Crayola crayons come in more than hues. Last year, Crayola introduced a new color. Crayola held an online contest to pick a name. The winning name was Bluetiful.
Does she have a favorite Crayola color? Of course! Robots are on the rise! Today, they can be found working in hotels and stores. Machines will soon be used to study sea creatures up close. Here's how Crayola makes the iconic but inedible color sticks.
Melt Twice a week, railcars full of uncolored paraffin wax pull up to the factory. An oil-filled boiler heats the cars with steam, and workers pump the now-molten glop into a silo. Each silo holds up to , pounds of wax, and the plant empties a silo nearly every day.
Mix From the silos, the wax moves through pipes to the mix kettles. Operators add a strengthening additive and dump in a bag of powdered pigment. The amount varies by the saturation and opacity of the color—yellow requires only a few pounds per pound batch; black requires a lot more. Pour Pumps move the newly colored liquid into a flat-topped, water-cooled steel rotary mold with crayon-shaped cavities.
