This is the mclaren 720s.
It's sleek, fast, and very expensive.
One of these supercars will set you back
Nearly $300,000.
Mclaren cars are a unique type of car.
They're something special.
They're not cars that people need,
They're cars that people want.
Narrator: The 720s is brought to life here
At the mclaren production center.
This 371,000 square foot facility
Was designed by superstar architect norman foster in 2004
At an estimated cost of $386 million.
And the inside of the mclaren production center
Is as impressive as its exterior.
It's bright, spacious, quiet, and extremely clean.
Most high volume car manufacturers,
You'll see hundreds of robots
Making thousands of identical cars.
Well, not here.
Narrator: Mclaren makes fewer than 5,000 cars a year
And each one is special.
Assembling a road car is a very, very complex process.
Mclaren make a car to order.
It's like a bespoke suit. They are handcrafted.
♪
Narrator: And that requires a very hands on approach
Down on the factory floor.
Because of their decades of experience
Building formula one race cars,
This individual craft-based approach to car manufacturing
Lies deep in mclaren's dna.
Breece mclaren, the founder, was from new zealand.
He built his first formula one car in 1966.
Only ferrari has been in the racing game longer.
In the early '90s, they got into road cars with the seminal f1.
A lot of the lessons of the racetrack
Are then brought over into their production cars.
Narrator: This is the main building block,
Or chassis of a mclaren car.
It's called a monocell or cage
And the rest of the car is built around it.
The monocells are premanufactured in austria
And are made from the same material
Used in the modern formula one race car.
One of the major parts or major materials we use
Is carbon fiber.
Carbon fiber is at the heart of every mclaren.
Mclaren revolutionized formula one
When they brought in carbon fiber in 1981.
It made the chassis five times lighter and 10 times stronger
And it is a key component in the road cars today.
If you compare carbon fiber
To something like aluminum or steel,
That can be strong, actually the strength to weight ratio
Of carbon fiber is what's so important.
You don't need very much of it to get the equivalent strength
Of a much bigger amount of another material.
Narrator: But what exactly is this wonder material,
Carbon fiber?
Carbon fiber is really high-performance
Composite material.
It's something which contains thin fibers of carbon,
Which on their own would be sort of floppy,
But they have a certain tensile strength to them.
And then those fibers are embedded in a polymer resin,
Which is strong and has a certain flexibility to it.
But actually, when you combine the two,
You get something that's greater than the sum of its parts.
You get a super lightweight high-performance material.
Narrator: Just like their formula one cars,
Mclarens road cars are designed with the driver in mind.
They are built and designed around the driver,
So the driver is literally at the center of the action.
And then the monocage and monocell
Designed around the occupant.
Narrator: As soon as the monocage
Chassis arrives on the production line,
The team starts to assemble a car around this
One essential building block.
The first stage is to add crumple zones
And crash protection around the car's interior.
It's then taken for what they call geometric
And surface validation.
Here, over 450 different points of the car
Are measured to make sure every curve, line,
And corner is perfectly aligned
And in proportion.
We ensure each mclaren car is perfect
In every detail.
Really, right from the off, right from when we start
The whole project it's almost like watchmaking.
Narrator: Once the body has passed
The surface validation test,
The team can then start to build up the car's exterior --
The wing panels, side panels,
And for non-convertibles -- the roof.
Now it's ready to be painted.
Before spraying,
The whole body is wrapped in plastic
And the individual panels are exposed,
Primed, and sanded flat.
Any contaminants are removed with an anti-static gun
And mclaren's secret to their supercar's high speed
Can be found in the painting process.
By using special particles within the paint
And a special paint process,
We're actually able to decrease the amount of paint
We have to put on the car.
And essentially deliver... [ speaks indistinctly ]
Narrator: It takes 24 hours to paint a typical mclaren car
And another 40 minutes in a hot oven for it to fully dry.
Finally, it's time to start putting the car together.
A loom of wires is fed through the car
To provide it with power.
A typical mclaren is made up of over a mile of cables
And 2,000 individual circuits.
Next, the beating heart of the car.
The most common engine type
Is the m83018, a 3.8 liter 90 degree twin turbo
Charged flat plain v8.
The mclaren 720 s goes from not 62 miles per hour
In 2.9 seconds.
Top speed -- 212 miles per hour.
♪
Narrator: Like most of the other parts
That make up the mclaren, the engine is made offsite.
For mclaren, outsourcing the parts
Makes the most economic sense.
To try to actually build every single little bit of a car
As well as assemble the cars themselves
Would be inefficient from a process perspective,
But also from a cost perspective.
Narrator: Back on the assembly line,
The brake discs and pistons are installed.
The brakes will slow these high-performance wheels
From 124 miles per hour
To zero in just 4.6 seconds.
Now another team finishes the interior of the car.
A mclaren supercar
Is made up of over 1,200 individual components.
It takes two to three weeks to put one of these cars together.
But no car is really complete until it's been taken
For a spin out on the test track.
♪
The final stage consists of an inspection and clean
And polish of the vehicle.
Then it's off to the customer and out onto the open road.
We have this incredible passion for what we do.
We're normally very, very precise
And logical in our approach.
But actually, no, the thing that drives it is pure passion.
Narrator: Mclaren is one of the world's
Most high-tech brands.
The skill and sophistication
Found inside their production center
Make it one of the world's most spectacular super factories.
Coming up, an american icon is
Chopping down the competition.
And later, new technology is keeping one of
The world's oldest writing traditions alive.
♪
Narrator: In a popular beach town along the east coast,
One factory is manufacturing
One of the most iconic products in america --
The mighty chainsaw.
With teeth turning at 60 miles per hour,
Some chainsaws can fell trees in minutes
And cut logs even faster.
Behind all that power is a polished production line
That harnesses more than 40 years of expertise and skill.
This is the steel super factory in virginia beach, virginia.
Inside this 1,000,000 square foot facility,
Man, machine, and robots
Assemble more than 12,000 products a day.
Once you get inside, you realize what a super factory is.
Narrator: Steel has produced a staggering 75 million
Chainsaws since it opened here in 1974.
But the origins of the chainsaw itself go back much further.
The first ever chainsaw wasn't invented by a lumberjack.
Actually, it was invented by a physician.
The concept of a saw tooth chain device dates
From the 18th century and was worked by hand
When surgeons needed a quick way to cut through bone.
Narrator: In the 1920s, inventors began looking for ways
To further develop the concept for the forest industry.
Swiss born, andreas stihl was one of the pioneers.
He produced his first powered chainsaw in 1926.
The advent of the chainsaw completely revolutionized
The forestry industry.
Before then, you had gangs of men
Toiling with axes and hand saws.
Now one man could do the work of a half a dozen,
And stihl's plans have come a long way.
♪
In the '70s, when we started,
We were just building one product --
A small handheld chainsaw.
But we always had a vision.
And now we are the world's largest selling chainsaw.
Narrator: Several hundred components make up a chainsaw.
It needs to have an incredible strength to weight ratio.
Magnus: The chainsaw is quite a complex machine.
You've got to start with the crankshaft,
The piston, and the cylinder.
Eventually, that crankshaft turns the clutch drum,
Which in turn, turns the chain on the bar,
Which you use to cut wood.
But it's not quite that simple.
There's a lot of parts in there that make that chain turn.
Narrator: Production of every chainsaw
Starts with the piston.
Its main function is to transfer explosive energy
From inside the engine to the cutting chain.
Leaves are like small racing engines,
Turning as many as 10 and 11,000 rpm piston.
It is the heart of the engine.
Narrator: Raw piston castings made of aluminum
Are placed into a machine to be shaped, drilled,
Cut, board, and finished
With computer controlled precision.
I know it just looks very simple,
But the intricate machining
Is not just a round piston.
It's actually oval shape in this direction
And barrel shape in this direction.
Narrator: These pistons need to be milled
With incredible precision.
They're measured in microns.
If I were to measure the thickness
Of a sheet of notebook paper,
It would measure .1 of a millimeter thick.
In order to achieve the micron,
You would have to slice the thickness
Of a sheet of notebook paper 100 times.
Narrator: The room for error on these pistons
Is just two microns
About 25 times smaller than the width of a human hair.
I have measured the outside diameter of pistons
And had fingerprints on the piston,
Making it out of specification.
♪
The perfect piston has been engineered,
But to transfer power to the cutting chain,
You need a crankshaft.
The crankshaft transfers that in and out, back and forth,
Energy of the piston into a rotational force,
And that rotation turns
The gears and fixes to an exact sprocket
That is the thing that's driving the chain round and round.
♪
Narrator: Using computerized milling machines,
The steel forgings are transformed
Into the crankshaft components
In just 12 seconds,
But before they can be used,
They need to be strengthened.
We're taking crankshafts and putting them
Inside of the furnace to make them very hot.
It's 1,700 degrees to make them porous.
So that way the air comes out
And the carbon is pumped in to harden the metal.
Narrator: The carbon-infused components are baked
At 3,900 degrees fahrenheit,
Which gives them an extremely durable
And wear-resistant surface.
The reason why they infuse the steel with carbon
Is basically to make it harder.
And the reason why they need to be hard or strong
Is because these components are under enormous stress.
Narrator: Once out of the oven, the parts are milled some more
And measured.
Anything two microns out of alignment will be rejected.
They are then assembled in a pressing station
Where over 27 tons of pressure can be applied.
Finally, the assembled crankshaft
Is checked for straightness,
Ensuring that it's balanced and runs smoothly.
But there's still a long way
To go before the finished chainsaw
Is ready to leave this factory floor.
To help move things along,
Stihl has invested in some high tech helpers.
♪
Narrator: From lumberjacks to landscapers,
Stihl makes a product for everyone.
And when it comes to chainsaws,
They are the number one selling brand in the world.
Inside stihl's state of the art super factory in virginia beach,
Robots mill, test, and deliver a continuous supply of parts
To the assembly line 24 hours a day.
Magnus: There's a central guidance system.
They know exactly where they're at out on the shop floor,
Which assembly line they're going to,
And which material they're dropping off
Or in some cases picking up.
When the battery gets low, they charge themselves up again,
Then they start back in operation.
Narrator: There is even a robot that threads
And ties the knot in the drawstring
That starts the engine.
But when we first started the first year,
We made 12,000 units that first year.
And the process back then was air screwdrivers
And a lot of hand assembly.
So the whole process has really evolved.
And right now, we're producing 12,000 units a day
Out of the facility here in virginia beach.
Narrator: With the engine assembled,
The next step is to make the polymer housing.
It all happens here in the polymer zone
At the north end of the factory.
What's in these are what we call gaylord boxes
Is a raw resin that is applied
To the injection molding machine.
One may be going to a motor housing,
One may be going to shroud.
♪
Narrator: The raw resin pellets
Are melted at extremely high temperatures
And injected under tons of pressure into custom made molds.
♪
The resin cools, hardens,
And forms the shape of the polymer part.
A chainsaw will turn its cutting chain
At over 10,000 revolutions per minute.
So to be able to safely hold and control the chainsaw,
Stihl has designed its polymer handle
To be lightweight and super strong.
To bring down weight and increase rigidity,
What we do is we actually come in here
And we have a needle valve that opens up,
Injects nitrogen through here and it'll escape
Out through here, through a dam gate.
And it just makes the part real rigid and real lightweight.
♪
Narrator: The chainsaw engine is built and housed,
But now it's time to assemble the business end.
This is a guide bar.
A guide bar is basically the blade of a chainsaw.
The part that the chain actually rides around.
Narrator: The process starts with rolls of steel.
Steel is an alloy of iron and carbon.
It's harder and stronger than iron.
To make the guide rail, a steel strip is cut
And stamped into three different pieces,
Which are then fed into a 20-ton metric press.
Here, they're bonded together
With a supercharged electric well
And then hardened with an induction heat treatment.
Well, the guide bar and the chain
Are obviously very critical to the function of a chainsaw
Because you need to cut wood.
The guide bar and the chain
Are matched according to the sprocket
That you have on.
They're different pitches of chain.
Depending on what kind of trees you're cutting
And the area you're cutting in.
Narrator: The chain is manufactured at another factory.
The cutting teeth and a top plate
Are angled at 30 degrees to aid cutting.

Finally, before they're shipped out,
Every chainsaw is started up and tested.

This is faber-castell,
The world's oldest and biggest pencil business.
And in this factory,
They have perfected a centuries old process,
Producing 2.3 billion pencils a year.
The scale is hard to believe.
And that is really a super factory.
Narrator: Faber-castell defines tradition.
Founded in 1761,
It's been in the same family for nine generations.
And despite the current age of computerization,
The pencil business is booming.
Sales have increased
By almost 10% in the last three years.
♪
Grown ups really got into coloring,
What, three, four years ago
When mindfulness was a thing and there was a big push
Towards life drawing and landscape drawings.
Narrator: Faber makes two basic types of pencil --
The traditional lead type
And a wide range of colored pencils.
They may seem similar on the surface,
But the materials that run through them
Are made in very different ways.
What we know as a lead pencil isn't actually made from lead,
But from a soft natural mineral called graphite,
Which was mistaken for lead back in the 16th century.
It was discovered that graphite made legible marks on paper.
So it was trimmed into thin strips wrapped in string.
And lo and behold, the pencil was born.
The word graphite literally means a stone for writing with.
This is a piece of graphite I've got here.
It's basically a crystalline form of carbon and carbon
Takes many forms.
On one end of the spectrum, you've got super hard diamonds.
And at the other end you've got these really soft graphite.
It's so soft. I can rub it off with my finger.
♪
Narrator: At faber, the pencil making process
Starts in the measuring room
Where graphite is mixed with clay and water.
The amount of clay
Will determine the grade of the finished pencil.
♪
We have 16 grades of pencil going from 8b to 6h.
8b pencil is really soft
Because it contains lots of graphite
Only a small amount of clay.
And the more you move towards the 6h,
The harder the pencil gets.
This is what the h stands for
And the more clay you start adding to the whole thing.
So it is really crucial to get the right ratio into that lead
Before actually starting the pencil making process.
Narrator: Different grades make a significant difference
To the look of a line on the page.
For technical work, hard grades are ideal.
While most artists prefer
The denser black line of the softer grades.
♪
When it comes to making colored pencils,
There's no graphite involved,
Different pigments are mixed with china clay or kaolin,
And combined with a binding agent to hold it all together.
♪
The mix is squeezed like thin toothpaste
Through a 2 millimeter hole,
Coming out in 18.5 centimeter pencil-sized lengths,
Graphite black or colored,
The leads are still soft and flexible.
At this stage.
So they're dried for 3 1/2 hours in an electric oven
At 248 degrees fahrenheit.
The colored leads are removed,
Any longer and their pigments would be destroyed.
But the graphite leads still aren't hard enough for writing.
So they're packed into a second oven
With a much higher temperature.
♪
After 45 minutes in the oven, the hardened graphite leads
Are doused into a wax bath.
This increases their strength,
Ensures a smooth stroke when writing or drawing,
And also helps with water resistance.
♪
So now we have our pieces of lead ready.
This is where the magic happens.
This is where we start making our pencils.
Narrator: Cedar and lindenwood are used to make up
The casings of faber pencils.
The wood arrives as precut slats.
What's important about the slats themselves is that
They have a really fine grain to allow once
For good production.
But later on, when the customer has the pencil
At home for good sharpening,
We don't want the wood to splinter.
We want it to sharpen nicely
And this is what we need the grain for.
Narrator: Each slat is exactly the length of a pencil,
But just half the thickness.
♪
First, grooves have to be cut in the slats.
Glue is now laid into each groove.
This will keep the leads firmly in place
When they're inserted into the wooden casing.
♪
Now, a second groove slat
Is placed exactly on top of the first.
The workers here call this das sandwich and each sandwich
Then goes into the drying wheel.
The sandwiches are in the drying wheel for one hour.
The wheel rotates, squeezes the sandwiches together,
And this way leaves no gap.
Just two pieces of wood glued together.
Narrator: A planing machine now cuts them into pencils,
Round, hexagonal, or triangular, depending on the time.
Up to 10 pencils can be cut from a single sandwich.
Faber prides themselves
On producing strong and durable pencils
Qualities they ensure by putting each one through a stress test.
To figure out if a pencil is good or not,
A quick way of doing so is to take a pencil,
Hold it at a 45 degree angle, and push down onto the scale.
And the pencil will not break before 2 1/2 kilos of pressure.
If it would break before,
We'd know there's something wrong with it
And test a couple of more to figure out what's wrong with it.
Let's see if the pencil that we've just made
Is of good quality.
So 45 degrees push down onto the scale
And two and a half.
Way past four or five kilos.
So that pencil is definitely good.
Narrator: The pencils that pass the stress test
Move on to the next stage --
The paint shop.
This is where the pencils get their first coating of paint.
The pencils come through the machine like that.
So basically from here to here, the felt ring would remove
All the leftover dust on the outside.
In here then is the paint.
In this case, dark green.
The blue ring here removes all the paint
Except for the pencil that has soaked into the wood
And the pencils that come out on the other end
Go onto the band and go through the drying tunnel
To have the paint dry.
Narrator: The graphite pencils are painted faber green
And the colored pencils
Are painted to match whatever color is on the inside.
Once the paint's dried, the pencils come back
And do this again.
They come back and do this again and they do this up to six times
Because the pencils need numerous layers of paint
To have a really nice finished coat.
Narrator: The company's logo, two jousting knights
Is stamped in gold leaf on every pencil,
And the colored pencils are also stamped
With their color identification.
In this case, cadmium red.
So the last thing that we're now missing
Is only the sharpening.
And, of course, quality control.
And this is what's happening here.
Narrator: Each pencil goes through a sharpening machine,
A combination of blades faster than the eye can see.
And an endless belt of sandpaper.

The articulated tankers,
And the network of industrial pipes,
This may look like an oil refinery,
But this massive factory is making something
Perhaps more important to the japanese --
Soy sauce.
And they're doing it on an industrial scale.
Shoda makes nearly 10 million gallons of soy sauce a year,
Enough to fill 15 olympic swimming pools.
Soy sauce is the most popular condiment in japan,
Featuring in 80% of dishes.
And I would wager if you open any cupboard
In any home across the country, you will find a bottle.
Narrator: Soy sauce is so important,
It's now being referred to as a fifth flavor.
In the west, we've traditionally talked about
Four flavors -- bitter, sweet, salty, and sour.
But in japan and now increasingly in the west,
We also acknowledge a flavor called umami,
Which roughly translates as savory or brothy.
Narrator: Scientists have identified
The common denominator of umami
Tasting foods as having a high concentration
Of certain amino acids.
Naturally brewed soy sauce is one of the most widely used
Umami ingredients in japanese cooking.
Shoda has eight supersized factories across japan,
Producing 375 million
Small bottles of soy sauce a year,
10 million of them are made right here.
Japanese tradition meets modern innovation
On a super scale in this super factory.
It's an intense, exacting process
And it all starts with a simple bean.
The soy bean comes from the pea family.
And it provides essential nutrition,
Especially protein, for millions of people.
It's comprised of about 17% oil
And a high protein content, making it very healthy.
It's economically the most important bean in the world.
Narrator: Making or to be more specific,
Brewing soy sauce, isn't new.
In fact, it's over 2000 years old.
It's a fermentation process similar to making alcohol
Where a few essential ingredients,
In this case soybeans,
Combined with bacteria and yeast to cause chemical reactions.
Those reactions bring out a host of over 200 different flavors
In the dark golden liquid that is soy sauce.
[ speaking japanese ]
The soybean has been farmed throughout asia
For thousands of years.
Chinese buddhist monks introduced soy sauce to japan
In the 7th century.
Narrator: 115 tons of defatted soybean flakes
Arrive at the factory every week.
They're hard and inedible at first,
So they need to be softened with a bit of heat.
The beans are put into a giant rotating pressure cooker
And steamed at 150 degrees for a few minutes.
The softened beans are then turned into a fine mash
By high speed blades that pound the mix to a pulp.
Wheat is the next ingredient.
A cutting machine with powerful blades slices through it
And reduces it to a powdery consistency.
But soy sauce's most important ingredient comes next.
And it's not something you'd normally want in your food.
In order for it to be called natural soy sauce,
It has to use mold.
♪
Narrator: At the shoda factory in japan,
Soy sauce is made using soybeans,
Wheat, and a third ingredient that may come as a surprise.
♪
Mold is a form of fungus and it gives soy sauce
Its distinct flavor and characteristics
During the fermentation process.
Together, soybeans, wheat, and mold
Make something called koji.
Koji has been declared the national fungus.
Not just because it's essential
For the brewing of traditional soy sauce,
But also because it's essential for other traditional japanese
Foods like rice vinegar, miso, and saki.
Narrator: The soybeans and wheat are combined.
It's then transported on a high speed production line
To a massive, heated room where it's put into a giant vat
And air is blown through it for 72 hours.
The mold reacts with the mix, breaking down the wheat
And beans releasing starch and sugars.
When it comes out, it looks slightly green.
♪
The second part of the fermentation process
Starts with salt.
It arrives in the factory in 11 ton tankers,
And the sodium chloride is dissolved in water
To produce a huge pool of 20% salt brine.
The brine is pumped through the koji mix.
It prevents the growth of any undesirable microorganisms
And acts as a preservative for the koji.
Once that's done, lactic acid bacteria,
Which is brine-friendly, is added along with yeasts
That further promote the fermentation process.
This transforms the koji into moromi.
The moromi mash is then transported by spiral pumps
Through a network of pipes
Into gigantic steel fermentation vats.
This plant alone has 50 in constant use,
It's stored for six months and watched over as the soy
And wheat paste turns into a semi-liquid,
Reddish brown, mature mash.
A lot of soy sauce you buy in shops will be made
Using chemical processes.
But the traditional method uses mold and is natural.
And in order for it to be called natural soy sauce,
It has to use mold.
Narrator: Aspergillus mold has broken down the grain protein
Into free amino acids
And the protein fragments into starches
And then into simple sugars.
Now the lactic acid bacteria ferments those sugars,

As well as its chemical composition
To determine how much nitrogen is present.
Then it's sent to the bottling plant
Where eight filling lines operate 24/7
To pump the sauce into bottles in seconds.
They can bottle over 20,000 gallons a day.

Narrator: Shoda produces several different styles
Of soy sauce at this plant.
Dark soy sauce has a higher bean content
And has been fermented for longer
Giving it a stronger flavor.
Light has more wheat
And is used for delicate foods.

And 120,000 gallons of commercial tins
Are all labeled and stored on 3,000 pallets.
They even pipe 26,000 gallons of soy sauce
Directly into trucks every day for commercial customers.
In the future, it's possible that advances in biotechnology
Might lead to shorter and better fermentation methods.
