Ever wonder how they make coils of sheet metal? This fascinating footage captured by Sweden’s Dalarna University at the SSAB hot rolling mill shows how a giant slab of steel is heated, then cleaned, roughed, and rolled through a series of machines into gradually thinner and thinner layers.
THE BEST Factories
We’ve seen what the insides of a bowling ball look like. Now see those balls get that way in this clip from How It’s Made, starting out with a soupy goo for its core, wrapped in polymer and polyurethane layers, and then sanded. We were most surprised by the odd shape of the core.
How It’s Made takes us inside of the Baby-Foot Sulpie factory, where they make premium foosball tables. Watch as the players are cast from molten metal, then painted before being assembled onto stainless steel rods and placed into their permanent places on a handcrafted wooden foosball field.
New York City sees many of its stop signs and other street signs vandalized or stolen each year. Between replacements and other projects, the Department of Transportation’s Queens sign shop makes over 100,000 new signs each year. Insider takes us inside the facility for a look at the work that goes into this laborious process.
Prima Power shows off the power and speed of one of its impressive fiber lasers. Their 6kW Laser Genius slices through sheet metal of varying thickness like a hot, razor-sharp knife through butter. We can’t believe how easily it got through that metal at 1:20. More laser porn here.
This footage from Chinese company Jiake Machine shows the process of taking coiled wire and transforming it into a sturdy mesh for fences or construction. The automated system pulls wires from dozens of spools, and feeds them through a massive welding rig that spot welds each intersection, with the mesh emerging from the other side.
As we’ve moved away from print and towards digital reading, highlighters aren’t as popular as they once were. But these fluorescent pens are still pretty cool for making art. Science Channel’s How It’s Made shows the process of molding the plastic bodies, filling their nibs with ink, and testing them for smooth flow.
When you pop open a bottle of wine, it’s easy to forget that its stopper comes from a tree. This footage captured by oenophile Jamie Goode at Portugal’s Cork Supply shows us the labor that goes into cutting pieces of cork tree bark, and punching out individual pieces. We wonder what they do with the leftover bark.
Popular Mechanics presents the best kind of factory video – one without narration or commentary. This clip will get your sweet tooth buzzing as workers at Hammond’s Candies plant make candy canes, marshmallows, and other goodies the old-fashioned way. The Denver-based company has been creating sweet treats since 1920.
Making waffle cones at home is pretty darned easy to do. But when you need to churn out millions of these tasty treats every month, you need some serious industrial equipment. In this classic video from How It’s Made, they show us just how factories mass-produce waffle, sugar, and cake cones.
While humans are still very much a part of assembling vehicles, robots are often used for the heavy lifting and dangerous tasks like painting and welding. Watch in awe as an army of 45 KUKA robots work in harmony at MAGNA Presstec to create frames for the Mercedes-Benz G-Class SUV.
This excerpt from Science Channel’s How It’s Made takes us inside of a factory that churns out millions of paintballs every year. It turns out these painful projectiles are basically made from the same stuff that gummy bears are made of – though we bet they don’t taste as good.
When you think about it, it’s pretty impressive how a tape measure can neatly coil up 15 or more feet of metal into a case you can clip onto your belt loop. Science Channel’s Machines: How They Work dissects the modern tape measure to show us its inner workings.
Spiral staircases offer a stylish way to add access to another level without taking up too much space, though they’re made in a very different way than traditional stairs. How It’s Made shows us the modern way of making these staircases using metal platforms and wood decks. The railings look like the trickiest part.
The Big Green Egg is one of the most desired objects for backyard cooks, with its ability to turn out delicious charcoal grilled foods year round. Now, take a trip inside the factory where they’re made, and see how their ceramic construction has more in common with making pottery than making conventional grills.
In this vintage 1959 newsreel from British Pathé, we go inside a UK factory where they transformed gold bars into incredibly thin sheets of gold leaf. According to the narrator, a single gold bar could cover 9000 square feet with the leaf it produced. We’ve got tendonitis just watching the guys doing the hand-hammering process.
In the mood for some ice cream cake? Check out this footage that Michael Wilson-Roberts captured inside UK ice cream maker Wall’s factory back in 2002, as machines churn out delicately rippled layers of ice cream and chocolate for those fancy looking Viennetta frozen desserts.
Discovery UK digs into the How It’s Made archives for this brief look at the process that goes into creating traditional magnets. After melting a cocktail of various metals in an electrical induction furnace, the fiery metal is poured into sand molds, then cooled, separated, and charged with multiple electromagnetic fields.
A classic segment from How It’s Made which shows the process of transforming latex rubber into condoms. Obviously, it’s important that they don’t break, but we’re not sure what real world scenario they’re trying to simulate with that inflation test. We’re thinking they just do that one for fun.
Ever wonder how they make basketballs or other bouncy rubber balls? It’s not as simple as just blowing up a rubber balloon. Science Channel’s How It’s Made visited a ball factory to walk us through the fascinating process, which includes making an inflatable bladder, then wrapping it in nylon thread and a segmented rubber skin.
It may not be Christmas quite yet, but it’s always a good time for candy. Sit back, relax and enjoy the fascinating process behind the creation of these colorful holiday treats, from machines that pull hot sugar, to ones that transform a 100 lb. block of candy into a thin and twisty rope.
We previously visited a speaker factory, but couldn’t share any video footage. How To has posted a pair of videos which show a bit more of the process. After the metal speaker baskets are prepared, it’s a time-consuming process to attach each part with just the right amounts of specific glues as each speaker spins around.
We’ve seen footage of pencils being made before, but the guys at Faber-Castell want us to know that their process is the best. Watch as they make black leads from graphite and clay, and colorful ones from powders and wax, then sandwich them into wooden shells, and paint them to match.
