Narrator:
Today, on "How it's made"...
4
00:00:25,931 --> 00:00:28,000
Mouth-blown window glass...
5
00:00:32,103 --> 00:00:33,965
...Water pumps...
6
00:00:38,068 --> 00:00:39,931
...Sake...
7
00:00:44,000 --> 00:00:45,793
...And tweezers.
8
00:00:52,344 --> 00:00:56,551
Before machine-made plate glass
Became popular in the 1920s,
9
00:00:56,551 --> 00:00:59,896
Window glass
Was blown by artisans.
10
00:00:59,896 --> 00:01:01,724
Today, specialty companies
11
00:01:01,724 --> 00:01:04,413
Still make window glass
The traditional way.
12
00:01:04,413 --> 00:01:07,827
While machine-made glass
Is uniformly clear and flat,
13
00:01:07,827 --> 00:01:11,344
Mouth-blown window glass
Has subtle variations.
14
00:01:14,172 --> 00:01:15,517
This german company
15
00:01:15,517 --> 00:01:21,103
Produces a wide variety
Of mouth-blown sheet glass.
16
00:01:21,103 --> 00:01:24,034
It's used to make
Contemporary wall light panels.
17
00:01:24,034 --> 00:01:27,965
It can also be used to make
Clear or stained glass windows.
18
00:01:31,931 --> 00:01:33,724
The company can make
Glass sheets
19
00:01:33,724 --> 00:01:37,172
In 5,000 different colors
And textures.
20
00:01:42,862 --> 00:01:46,241
This furnace melts silica sand
And other natural materials
21
00:01:46,241 --> 00:01:48,206
Into glass.
22
00:01:48,206 --> 00:01:51,103
The starter begins by inserting
The end of a blowpipe
23
00:01:51,103 --> 00:01:52,758
Into a furnace.
24
00:01:56,758 --> 00:01:59,517
He takes a small amount
Of colorless molten glass
25
00:01:59,517 --> 00:02:00,793
Out of the furnace
26
00:02:00,793 --> 00:02:03,103
And rotates it
In a wooden mold.
27
00:02:03,103 --> 00:02:04,965
The mold is lined
With heavy paper
28
00:02:04,965 --> 00:02:08,758
To soften the surface.
29
00:02:08,758 --> 00:02:11,241
Then, he inserts a metal needle
Through the blowpipe
30
00:02:11,241 --> 00:02:13,482
To create a pathway for air.
31
00:02:19,482 --> 00:02:23,413
He returns to the furnace
For more molten glass.
32
00:02:23,413 --> 00:02:26,068
The artisans make multiple trips
To the furnace,
33
00:02:26,068 --> 00:02:28,137
Shaping the molten glass
In stages
34
00:02:28,137 --> 00:02:31,379
So it's easier to handle.
35
00:02:31,379 --> 00:02:36,379
This time, the assistant shapes
The glass with a large mold.
36
00:02:36,379 --> 00:02:37,655
When the shape is set,
37
00:02:37,655 --> 00:02:39,896
The assistant
Prepares it for blowing.
38
00:02:39,896 --> 00:02:42,241
He uses a fork tool
To push the glass
39
00:02:42,241 --> 00:02:45,517
To the top of the pipe.
40
00:02:45,517 --> 00:02:48,827
The starter rotates the glass
In a larger, paper-lined mold
41
00:02:48,827 --> 00:02:50,448
To round it further.
42
00:02:53,034 --> 00:02:54,827
The molten glass
Cools rapidly
43
00:02:54,827 --> 00:02:57,862
Once it comes
Out of the furnace.
44
00:02:57,862 --> 00:03:00,620
If the temperature
Dips below 1,800 degrees,
45
00:03:00,620 --> 00:03:02,448
It's not longer workable.
46
00:03:02,448 --> 00:03:07,275
So the team must work quickly
And reheat the glass repeatedly.
47
00:03:07,275 --> 00:03:09,793
Another assistant
Lubricates the blowpipe
48
00:03:09,793 --> 00:03:12,896
So it will rotate easily
On the support stand.
49
00:03:12,896 --> 00:03:16,758
The starter hands the glass
Over to the master glassblower.
50
00:03:16,758 --> 00:03:18,896
First, he rotates the blowpipe
51
00:03:18,896 --> 00:03:21,586
To straighten and center
The drooping glass.
52
00:03:21,586 --> 00:03:24,241
Then, he begins turning
And blowing into the pipe
53
00:03:24,241 --> 00:03:27,034
To gradually inflate the glass.
54
00:03:27,034 --> 00:03:29,448
This requires great
Physical strength
55
00:03:29,448 --> 00:03:34,103
As well as tremendous artistic
And technical skill.
56
00:03:34,103 --> 00:03:38,689
The pipe and glass weigh
Over 30 pounds combined.
57
00:03:38,689 --> 00:03:40,862
When the glass starts to cool,
58
00:03:40,862 --> 00:03:43,482
The assistant
Reheats it in a smaller oven.
59
00:03:43,482 --> 00:03:45,965
He passes the pipe
Back to the glassblower,
60
00:03:45,965 --> 00:03:48,172
Who then resumes inflating it.
61
00:03:52,206 --> 00:03:54,448
This time,
He swings it upside-down,
62
00:03:54,448 --> 00:03:59,275
Using gravity to help
Elongate the shape.
63
00:03:59,275 --> 00:04:04,103
Next, he will transform the
Glass balloon into a cylinder.
64
00:04:04,103 --> 00:04:08,344
First, he reheats
The tip of the glass
65
00:04:08,344 --> 00:04:10,586
And weakens it
With a hot burner.
66
00:04:12,758 --> 00:04:16,034
Then, he reheats
The entire glass cylinder.
67
00:04:16,034 --> 00:04:18,137
This expands the air inside
68
00:04:18,137 --> 00:04:21,068
And forces
The weakened tip open.
69
00:04:21,068 --> 00:04:23,137
The glassblower taps
The opposite side
70
00:04:23,137 --> 00:04:26,517
Of the hot glass
With a cold metal stick.
71
00:04:26,517 --> 00:04:29,620
The thermal shock
Causes a neat stress break.
72
00:04:29,620 --> 00:04:33,586
This releases the glass
From the blowpipe.
73
00:04:33,586 --> 00:04:35,620
Then, the assistant
Slices it lengthwise
74
00:04:35,620 --> 00:04:38,448
With a glass cutter
75
00:04:38,448 --> 00:04:41,931
And hands it off
To the flattening team.
76
00:04:41,931 --> 00:04:45,827
Their job is to transform
The cylinder into sheet glass.
77
00:04:45,827 --> 00:04:47,551
The flattening master's
Assistant
78
00:04:47,551 --> 00:04:51,137
Puts the cylinder
Into a furnace.
79
00:04:51,137 --> 00:04:55,620
It's heated
To over 1,500 degrees.
80
00:04:55,620 --> 00:04:58,344
The glass softens
In about 30 minutes.
81
00:04:58,344 --> 00:04:59,862
Then, the flattening master
82
00:04:59,862 --> 00:05:02,620
Reaches into the opposite end
Of the furnace with a stick
83
00:05:02,620 --> 00:05:06,827
And gently opens the cylinder.
84
00:05:06,827 --> 00:05:08,793
Next, the flattening master
85
00:05:08,793 --> 00:05:14,103
Irons the glass sheet
With a special wooden tool.
86
00:05:14,103 --> 00:05:16,517
The flat sheet
Goes into the annealing oven
87
00:05:16,517 --> 00:05:19,275
For a gradual
Controlled cooldown.
88
00:05:19,275 --> 00:05:23,137
This relieves stress
And prevents cracking.
89
00:05:23,137 --> 00:05:24,965
The flatting master's assistant
90
00:05:24,965 --> 00:05:27,034
Removes the glass
From the annealing oven
91
00:05:27,034 --> 00:05:29,551
And performs
A visual inspection.
92
00:05:32,379 --> 00:05:35,241
The last step is
To cut the edges straight.
93
00:05:37,379 --> 00:05:39,793
To make multicolored
And textured glass,
94
00:05:39,793 --> 00:05:45,172
They add additional ingredients
During the melting process.
95
00:05:45,172 --> 00:05:48,551
Mouth-blown window glass
Contains natural variations
96
00:05:48,551 --> 00:05:53,517
That play with the light
And create a subtle glow,
97
00:05:53,517 --> 00:05:57,241
A glow that machine-made
Window glass can't replicate.
98
00:06:06,275 --> 00:06:09,172
Narrator:
Water is essential for life.
99
00:06:09,172 --> 00:06:12,379
But most of earth's fresh water
Is trapped underground.
100
00:06:12,379 --> 00:06:15,793
To tap into these reservoirs,
We need water pumps.
101
00:06:15,793 --> 00:06:19,034
They've existed in many forms
For thousands of years.
102
00:06:19,034 --> 00:06:21,724
The designs
Have improved over time,
103
00:06:21,724 --> 00:06:25,758
And today's water pumps are
Truly an underground success.
104
00:06:29,620 --> 00:06:32,310
For farmers
And municipal water providers,
105
00:06:32,310 --> 00:06:36,689
The turbine water pump
Is a workhorse.
106
00:06:36,689 --> 00:06:38,827
It can pump thousands
Of gallons of water
107
00:06:38,827 --> 00:06:40,896
Out of the ground every minute.
108
00:06:43,241 --> 00:06:45,241
They start by making
Diffuser bowls
109
00:06:45,241 --> 00:06:48,827
Using urn-shaped castings.
110
00:06:48,827 --> 00:06:53,103
One turbine pump could have
Up to 30 diffuser bowls.
111
00:06:53,103 --> 00:06:56,275
The bowls hold
The pump's spinning impellers.
112
00:06:56,275 --> 00:06:58,793
Computerized tools
Refine their shape
113
00:06:58,793 --> 00:07:01,689
So the bowls fit neatly
In the pump column.
114
00:07:01,689 --> 00:07:04,896
Another set of tools
Carve the bronze impellers.
115
00:07:04,896 --> 00:07:06,482
They fine-tune the casings
116
00:07:06,482 --> 00:07:11,586
So that the impellers will fit
Into the diffuser bowls.
117
00:07:11,586 --> 00:07:15,068
Here's a look at both sides
Of the finished impellers.
118
00:07:15,068 --> 00:07:18,172
An uneven impeller
Will vibrate when spinning.
119
00:07:18,172 --> 00:07:22,068
A technician uses this machine
To check for imbalances.
120
00:07:22,068 --> 00:07:24,206
When sensors locate the problem,
121
00:07:24,206 --> 00:07:26,379
He sands down the metal
In that area.
122
00:07:26,379 --> 00:07:28,275
This balances the impeller.
123
00:07:28,275 --> 00:07:31,034
Next, a machine
124
00:07:31,034 --> 00:07:34,448
Carves the top attachment ring
Of the discharge head.
125
00:07:36,482 --> 00:07:40,482
The discharge head
Shields the motor from water.
126
00:07:40,482 --> 00:07:44,758
It also changes the water flow
From vertical to horizontal.
127
00:07:44,758 --> 00:07:47,344
Next, a machine
Carves the outflow flange
128
00:07:47,344 --> 00:07:51,827
And drills holes
For attaching a gasket.
129
00:07:51,827 --> 00:07:55,068
An employee
Paints the part blue.
130
00:07:55,068 --> 00:07:57,862
The paint protects the metal
Against rust.
131
00:08:00,413 --> 00:08:02,931
He also highlights
The embossed company name
132
00:08:02,931 --> 00:08:05,034
With bright red paint.
133
00:08:05,034 --> 00:08:08,103
Here are the machine parts
Before and after painting.
134
00:08:08,103 --> 00:08:12,275
Next, they make
The pump's shaft pipes.
135
00:08:12,275 --> 00:08:15,482
Tools work on both ends
Of the pipes simultaneously
136
00:08:15,482 --> 00:08:17,413
To refine the inner diameter.
137
00:08:17,413 --> 00:08:19,724
Then, they carve threads
Into them.
138
00:08:19,724 --> 00:08:22,379
They clean the pipes, then
Roll them into the holding area.
139
00:08:27,344 --> 00:08:29,206
Next, computerized tools
140
00:08:29,206 --> 00:08:32,379
Cut threads
Into the bronze bearings.
141
00:08:32,379 --> 00:08:33,965
These threads will interconnect
142
00:08:33,965 --> 00:08:36,206
With the ones
On the shaft pipes.
143
00:08:38,413 --> 00:08:40,620
A worker screws
The completed bearings
144
00:08:40,620 --> 00:08:45,034
Into the ends
Of the shaft pipes.
145
00:08:45,034 --> 00:08:49,103
Then, he screws the pipes
Together in a loose preassembly.
146
00:08:51,137 --> 00:08:56,827
He brushes lubricant onto the
Exposed section of the bearings.
147
00:08:56,827 --> 00:09:01,896
He links four pipes
To create one 20-foot pipe.
148
00:09:01,896 --> 00:09:04,482
He sets the long pipe
In a cradle-like device
149
00:09:04,482 --> 00:09:07,655
And activates the drive wheel.
150
00:09:07,655 --> 00:09:11,517
As the pipes tighten,
The bearing disappears inside.
151
00:09:17,689 --> 00:09:21,551
The worker inserts a steel shaft
Into each 20-foot pipe.
152
00:09:25,689 --> 00:09:29,448
He caps the ends to secure
The shafts inside the pipes.
153
00:09:33,275 --> 00:09:35,931
This wider pipe
Is called the column pipe.
154
00:09:35,931 --> 00:09:39,206
An employee attaches
An assembly flange to each end
155
00:09:39,206 --> 00:09:41,344
And secures it with bolts.
156
00:09:44,172 --> 00:09:47,448
A worker connects a suction bell
To one of the shafts.
157
00:09:47,448 --> 00:09:51,103
The suction bell will draw
The well water into the pump.
158
00:09:51,103 --> 00:09:53,931
Then, he slides an impeller
Into place.
159
00:09:57,724 --> 00:09:59,862
He secures the impeller
To the shaft
160
00:09:59,862 --> 00:10:02,310
With a tapered clamp
Called a collet.
161
00:10:02,310 --> 00:10:05,482
He encases the impeller
In an iron diffuser bowl.
162
00:10:05,482 --> 00:10:08,137
He bolts the diffuser bowl
To the suction bell.
163
00:10:10,000 --> 00:10:11,275
They add more impellers
164
00:10:11,275 --> 00:10:13,620
To increase the power
Of the water pump.
165
00:10:13,620 --> 00:10:15,000
A more powerful pump
166
00:10:15,000 --> 00:10:18,172
Will be able to extract water
From deeper underground.
167
00:10:22,931 --> 00:10:25,275
They apply protective paint
To the pump,
168
00:10:25,275 --> 00:10:27,517
And then,
It's ready to install.
169
00:10:29,965 --> 00:10:32,517
On site,
Workers use special equipment
170
00:10:32,517 --> 00:10:35,000
To help guide the pump
Into the well.
171
00:10:37,034 --> 00:10:39,551
They join the shaft pipe
To the pump.
172
00:10:42,241 --> 00:10:46,482
Then, they slide the column pipe
Around the shaft pipe
173
00:10:46,482 --> 00:10:48,793
And bolt it to the top
Of the pump.
174
00:10:51,896 --> 00:10:55,103
The team adds more shaft pipe
For a deeper reach.
175
00:10:55,103 --> 00:10:57,793
Then,
They install the discharge head.
176
00:11:00,655 --> 00:11:03,620
This turbine pump
Is now ready to extract water
177
00:11:03,620 --> 00:11:06,310
From great depths underground.
178
00:11:17,413 --> 00:11:20,103
Narrator:
Sake is japanese rice wine.
179
00:11:20,103 --> 00:11:23,137
It's distinguished
By two main factors --
180
00:11:23,137 --> 00:11:26,379
How the rice is milled
Before fermentation,
181
00:11:26,379 --> 00:11:28,379
And whether there's
Any distilled alcohol
182
00:11:28,379 --> 00:11:30,655
Added to the final blend.
183
00:11:30,655 --> 00:11:32,344
Sake can be mass-produced
184
00:11:32,344 --> 00:11:34,827
Or handcrafted
The traditional way.
185
00:11:37,379 --> 00:11:39,103
This canadian microbrewery
186
00:11:39,103 --> 00:11:42,551
Only makes pure rice wine
Called junmai-shu.
187
00:11:42,551 --> 00:11:46,137
The brewery doesn't add
Any extra alcohol to their sake.
188
00:11:46,137 --> 00:11:48,206
The clear sake, known as seishu,
189
00:11:48,206 --> 00:11:51,103
Have a subtle, fruitier,
Nutty flavor.
190
00:11:51,103 --> 00:11:53,655
Cloudier sake is called nigori.
191
00:11:53,655 --> 00:11:55,103
It contains rice sediment,
192
00:11:55,103 --> 00:11:59,172
Which produces
Its creamier texture.
193
00:11:59,172 --> 00:12:02,275
The rice is milled before
It arrives at the brewery.
194
00:12:02,275 --> 00:12:04,448
Milling removes
The proteins and lipids
195
00:12:04,448 --> 00:12:06,931
On the outside layers
Of the rice grain.
196
00:12:09,103 --> 00:12:12,689
This rice has 30 percent
Of its grain milled away.
197
00:12:12,689 --> 00:12:15,620
The starch of the core
Will produce premium sake.
198
00:12:15,620 --> 00:12:17,482
First, they wash the rice.
199
00:12:17,482 --> 00:12:19,793
Then, the pour it
In a porous bag
200
00:12:19,793 --> 00:12:22,137
And soak it
In cold filtered water.
201
00:12:22,137 --> 00:12:26,482
The brewmaster checks the rice
With his hands.
202
00:12:26,482 --> 00:12:29,034
Once it reaches
The right consistency,
203
00:12:29,034 --> 00:12:31,068
They drain the bag overnight.
204
00:12:31,068 --> 00:12:33,689
Then, they pour the rice
Into a steamer.
205
00:12:39,413 --> 00:12:43,000
The steamer cooks the rice under
Pressure for about an hour.
206
00:12:43,000 --> 00:12:44,758
They cover the steamer
With cloth
207
00:12:44,758 --> 00:12:48,413
To contain the rice as it cooks.
208
00:12:48,413 --> 00:12:53,413
The steamer softens the rice
But doesn't overcook it.
209
00:12:53,413 --> 00:12:55,172
To ferment at the right speed,
210
00:12:55,172 --> 00:12:58,344
The rice needs to be firm
On the outside and soft
211
00:12:58,344 --> 00:13:01,620
In the center.
212
00:13:01,620 --> 00:13:04,137
Workers separate the rice
By hand,
213
00:13:04,137 --> 00:13:08,379
Then use fans to cool the rice
Down to about 98 degrees.
214
00:13:08,379 --> 00:13:11,482
Next, they transfer it
To a heated room.
215
00:13:11,482 --> 00:13:12,896
They spread out the rice
216
00:13:12,896 --> 00:13:17,931
And cover it with mold spores
Imported from japan.
217
00:13:17,931 --> 00:13:21,241
When heated, the spores
Germinate and grow on the rice.
218
00:13:21,241 --> 00:13:23,724
The spores secrete enzymes
219
00:13:23,724 --> 00:13:28,896
That will transform the starch
Into fermentable sugars.
220
00:13:28,896 --> 00:13:32,241
Workers insert a thermometer
Into the rice
221
00:13:32,241 --> 00:13:36,172
Then wrap it in cloth
To hold in the heat.
222
00:13:36,172 --> 00:13:37,862
48 hours later,
223
00:13:37,862 --> 00:13:40,862
The sweet rice, called koji,
Is ready.
224
00:13:40,862 --> 00:13:44,413
Now, they begin
The fermentation process.
225
00:13:44,413 --> 00:13:47,965
They mix 3/4 of steamed rice
With 1/4 of koji
226
00:13:47,965 --> 00:13:50,724
In a temperature-controlled
Fermentation tank.
227
00:13:50,724 --> 00:13:53,551
Then, they add spring water
And yeast.
228
00:13:53,551 --> 00:13:55,172
The mold enzymes in the koji
229
00:13:55,172 --> 00:13:59,448
Convert the starch
In the steamed rice into sugars.
230
00:13:59,448 --> 00:14:03,275
The yeast consumes those sugars
And produces alcohol.
231
00:14:03,275 --> 00:14:07,482
The process takes
About three weeks.
232
00:14:07,482 --> 00:14:10,206
The brewmaster checks
The temperature, acidity,
233
00:14:10,206 --> 00:14:14,689
Residual sugar,
And alcohol levels every day.
234
00:14:14,689 --> 00:14:18,793
When the brew is ready,
They pour it into cloth bags.
235
00:14:18,793 --> 00:14:21,655
They neatly stack the bags
In a traditional japanese
236
00:14:21,655 --> 00:14:23,413
Mechanical press.
237
00:14:26,655 --> 00:14:30,310
Large sake breweries
Automate this entire process,
238
00:14:30,310 --> 00:14:31,896
But this smaller operation
239
00:14:31,896 --> 00:14:36,310
Follows century-old traditions
And does everything by hand.
240
00:14:36,310 --> 00:14:38,068
As the press fills up,
241
00:14:38,068 --> 00:14:42,241
The weight of the bags
Kick-starts the pressing.
242
00:14:42,241 --> 00:14:45,689
They seal the press
With heavy steel plates
243
00:14:45,689 --> 00:14:48,000
And mount
The pressing mechanism.
244
00:14:50,413 --> 00:14:52,034
As they turn the crank,
245
00:14:52,034 --> 00:14:55,931
The press squeezes
All the liquid out of the bags.
246
00:14:55,931 --> 00:14:57,137
When they're done,
247
00:14:57,137 --> 00:15:01,620
Only unfermented rice
Will be left behind.
248
00:15:01,620 --> 00:15:03,689
The liquid sake
Drains out of a spout
249
00:15:03,689 --> 00:15:05,620
At the base of the press.
250
00:15:12,551 --> 00:15:15,034
They age the sake
In refrigerated tanks
251
00:15:15,034 --> 00:15:16,931
For up to 4 months.
252
00:15:19,551 --> 00:15:25,862
As it ages, the sake develops
Deeper and more complex flavors.
253
00:15:25,862 --> 00:15:28,896
Not only is this sake
Entirely handcrafted,
254
00:15:28,896 --> 00:15:32,172
It's also hand-bottled.
255
00:15:32,172 --> 00:15:34,551
Workers use
A gravity-fed filling machine
256
00:15:34,551 --> 00:15:37,344
To pour sake
Into these glass bottles.
257
00:15:37,344 --> 00:15:40,655
The dark bottles
Protects the sake from uv rays,
258
00:15:40,655 --> 00:15:43,000
Which would spoil its color
And flavor.
259
00:15:43,000 --> 00:15:46,517
Next,
They add the aluminum twist cap.
260
00:15:46,517 --> 00:15:49,172
A machine molds it to the shape
Of the bottleneck
261
00:15:49,172 --> 00:15:52,724
And crimps the bottom rim.
262
00:15:52,724 --> 00:15:54,620
They apply a label
To each bottle
263
00:15:54,620 --> 00:15:58,517
With a simple
Hand-crank machine.
264
00:15:58,517 --> 00:16:03,000
Full-strength sake has an
Alcohol content of 18 percent.
265
00:16:03,000 --> 00:16:05,103
Some sake is diluted
With spring water
266
00:16:05,103 --> 00:16:08,310
To bring the alcohol content
Down before bottling.
267
00:16:10,482 --> 00:16:14,758
The sake this brewery
Produces is unpasteurized.
268
00:16:14,758 --> 00:16:19,448
This enhances the flavor
But requires refrigeration.
269
00:16:33,379 --> 00:16:37,482
Narrator:
Tweezers were first used
In ancient egypt and rome.
270
00:16:37,482 --> 00:16:41,137
These indispensable tools
Help us grip small objects.
271
00:16:41,137 --> 00:16:42,931
We use tweezers
To pull splinters
272
00:16:42,931 --> 00:16:45,758
And unwanted hair
From our skin.
273
00:16:45,758 --> 00:16:47,655
They can also handle
The tiny parts
274
00:16:47,655 --> 00:16:50,517
Found in mechanical devices,
Like watches.
275
00:16:54,206 --> 00:16:56,689
When something small
Eludes our grasp,
276
00:16:56,689 --> 00:16:58,689
Tweezers help us pick them up.
277
00:16:58,689 --> 00:17:01,758
They act as an extension
Of our forefinger and thumb,
278
00:17:01,758 --> 00:17:05,793
Allowing us to grab and hold on
To the tiniest things.
279
00:17:05,793 --> 00:17:08,344
First, a worker
Preps the tweezer mold
280
00:17:08,344 --> 00:17:13,448
By grinding and sanding around
The tweezer-shaped cavity.
281
00:17:13,448 --> 00:17:14,724
This smoothes the mold,
282
00:17:14,724 --> 00:17:19,137
Making it easier to cut out
The metal parts.
283
00:17:19,137 --> 00:17:22,965
A worker buffs the mold to give
The surface a glossy finish.
284
00:17:29,413 --> 00:17:31,000
A computer-guided machine
285
00:17:31,000 --> 00:17:33,931
Carves a die cutter
Out of a steel block.
286
00:17:33,931 --> 00:17:36,344
It uses
An electrified brass wire
287
00:17:36,344 --> 00:17:38,172
To slice through the steel.
288
00:17:39,827 --> 00:17:43,620
The die cutter perfectly
Matches the tweezer mold.
289
00:17:43,620 --> 00:17:45,172
After the tools are prepped,
290
00:17:45,172 --> 00:17:47,586
They're ready
To make the tweezers.
291
00:17:47,586 --> 00:17:49,586
A coil of thick
Stainless steel wire
292
00:17:49,586 --> 00:17:53,551
Unwinds into
The molding machine.
293
00:17:53,551 --> 00:17:55,827
Rollers straighten out
The kinks.
294
00:17:59,275 --> 00:18:01,517
An automated device
Grabs the wire
295
00:18:01,517 --> 00:18:04,241
And pulls it between
The die-cutter and the mold.
296
00:18:08,551 --> 00:18:11,103
The die-cutter pushes the wire
Into the mold
297
00:18:11,103 --> 00:18:13,517
And cuts out the shape it needs.
298
00:18:13,517 --> 00:18:15,379
The excess steel slides out,
299
00:18:15,379 --> 00:18:19,000
And a spool
Collects it for recycling.
300
00:18:19,000 --> 00:18:22,965
The mold ejects the part
Into a bin.
301
00:18:22,965 --> 00:18:25,827
They are a little thinner
At the gripping end.
302
00:18:25,827 --> 00:18:30,172
This design gives the tweezers
More flexibility.
303
00:18:30,172 --> 00:18:32,241
An employee places two
Of the parts
304
00:18:32,241 --> 00:18:35,068
In an induction welder.
305
00:18:35,068 --> 00:18:36,344
He activates the welder
306
00:18:36,344 --> 00:18:38,827
To fuse it twice
At the gripping end.
307
00:18:40,827 --> 00:18:43,344
A double weld
Reinforces the joint,
308
00:18:43,344 --> 00:18:46,965
Making it very difficult
To pull the tweezers apart.
309
00:18:51,379 --> 00:18:54,310
This welder assembles
Approximately 3,000 pairs
310
00:18:54,310 --> 00:18:56,034
Of tweezers per shift.
311
00:18:59,965 --> 00:19:02,827
Each pair of tweezers
Is thoroughly polished
312
00:19:02,827 --> 00:19:06,413
To make them smoother
And easier to grip.
313
00:19:06,413 --> 00:19:10,241
It's a multi-step process.
314
00:19:10,241 --> 00:19:13,482
First, an employee
Sands the body of the tweezers
315
00:19:13,482 --> 00:19:17,931
Using fine abrasive paper
And polishing cream.
316
00:19:17,931 --> 00:19:22,137
Next, the tweezers
Go into a vibrating polisher.
317
00:19:22,137 --> 00:19:24,344
They bounce around
With ceramic stones
318
00:19:24,344 --> 00:19:28,931
And various polishing solutions
For 24 hours.
319
00:19:28,931 --> 00:19:31,931
After that, they
Wash off the chemical residue.
320
00:19:31,931 --> 00:19:35,068
Then, they filter
And neutralize the water.
321
00:19:35,068 --> 00:19:36,448
Using another device,
322
00:19:36,448 --> 00:19:39,758
They shoot fine glass particles
At the tweezers.
323
00:19:39,758 --> 00:19:42,172
This gives them a satin finish
That's durable
324
00:19:42,172 --> 00:19:43,931
And resists scratching.
325
00:19:47,068 --> 00:19:50,655
A worker levels a tweezers' tips
Using a sanding belt.
326
00:19:53,241 --> 00:19:54,896
She makes sure
The claw-like tips
327
00:19:54,896 --> 00:19:57,448
Are exactly the same length
And angle.
328
00:20:02,517 --> 00:20:05,379
Another member of the team
Sands the inside of the tips
329
00:20:05,379 --> 00:20:08,137
Using a very fine abrasive disc.
330
00:20:08,137 --> 00:20:10,586
This will improve
The tweezer's grip.
331
00:20:18,000 --> 00:20:21,206
The factory also
Makes carbon steel tweezers.
332
00:20:21,206 --> 00:20:24,517
They're a cheaper alternative
To stainless steel.
333
00:20:24,517 --> 00:20:27,689
They immerse the carbon steel
Tweezers in a chrome solution
334
00:20:27,689 --> 00:20:30,310
To protect them from rust.
335
00:20:30,310 --> 00:20:34,689
The tweezers' electrical charge
Attracts the chrome.
336
00:20:34,689 --> 00:20:38,034
The result is a shiny
And protective chrome plating.
337
00:20:40,689 --> 00:20:46,689
Next, an employee prepares the
Tweezers for laser lettering.
338
00:20:46,689 --> 00:20:48,379
She places them in a fixture
339
00:20:48,379 --> 00:20:51,068
And selects the image
On her computer.
340
00:20:54,310 --> 00:20:55,758
She activates the laser,
341
00:20:55,758 --> 00:20:58,827
And it permanently etches
The graphics onto the metal.
342
00:21:05,103 --> 00:21:09,344
Next, she rubs special oil
Onto the surface of the metal
343
00:21:09,344 --> 00:21:11,965
And cleans the tweezers
Thoroughly.
344
00:21:15,206 --> 00:21:18,448
She also inspects the tweezers
For any cosmetic flaws
345
00:21:18,448 --> 00:21:20,965
And makes sure
They function properly.
346
00:21:25,275 --> 00:21:28,655
These tweezers are now
Ready for plucking, primping,
347
00:21:28,655 --> 00:21:30,896
And any other small jobs.
