That work and react to humans.
7
00:01:03,862 --> 00:01:07,068
The term "Robot"
First appeared in 1920.
8
00:01:07,068 --> 00:01:09,379
It comes from
The czech word "Robota,"
9
00:01:09,379 --> 00:01:14,413
Meaning "Forced labor."
10
00:01:14,413 --> 00:01:17,586
This facility makes
A type of educational robot
11
00:01:17,586 --> 00:01:21,068
Equipped with a series
Of interconnected servomotors.
12
00:01:21,068 --> 00:01:23,344
This type of equipment
Allows the robot
13
00:01:23,344 --> 00:01:27,586
To move with an extraordinary
Degree of dexterity.
14
00:01:27,586 --> 00:01:30,103
Construction starts
From scratch.
15
00:01:30,103 --> 00:01:32,965
Tiny bushings are created
From a steel rod
16
00:01:32,965 --> 00:01:39,137
Placed inside this high-tech
Automated machining device.
17
00:01:39,137 --> 00:01:41,655
A technician monitors
The operation
18
00:01:41,655 --> 00:01:45,344
As the machine shapes the parts
With digitized precision
19
00:01:45,344 --> 00:01:48,000
To the design specifications.
20
00:01:48,000 --> 00:01:49,620
The high-speed steel bits
21
00:01:49,620 --> 00:01:52,758
Carve the metal
At an incredible speed.
22
00:01:52,758 --> 00:01:56,517
This machine can
Manufacture 1,309 parts
23
00:01:56,517 --> 00:02:01,655
Per every eight-hour shift.
24
00:02:01,655 --> 00:02:04,344
The parts fall into
A vibrating mechanism
25
00:02:04,344 --> 00:02:10,448
That feeds them into
The next phase of production.
26
00:02:10,448 --> 00:02:13,758
A specialized device
Called a gear-hobbing machine
27
00:02:13,758 --> 00:02:16,827
Quickly and accurately cuts
A series of cogs
28
00:02:16,827 --> 00:02:19,413
To create tiny sprocket wheels.
29
00:02:25,482 --> 00:02:28,586
A technician uses
State-of-the-art
Measuring devices
30
00:02:28,586 --> 00:02:31,620
To gauge the profile,
Tooth alignment, and pitch
31
00:02:31,620 --> 00:02:32,931
Of sample parts
32
00:02:32,931 --> 00:02:35,482
To ensure they are up to
Standards specified
33
00:02:35,482 --> 00:02:41,034
In the manufacturer's
Control plan.
34
00:02:41,034 --> 00:02:44,275
Another operator mounts
A gear plate on a device,
35
00:02:44,275 --> 00:02:47,758
Fastening it to a smaller part
Called the sun gear.
36
00:02:54,827 --> 00:02:59,310
Once all the required parts
Are tested and prepped,
37
00:02:59,310 --> 00:03:01,793
Technicians begin
Putting them all together
38
00:03:01,793 --> 00:03:06,172
To create d.C. Motors.
39
00:03:06,172 --> 00:03:08,724
Since the robots
Are specialty items
40
00:03:08,724 --> 00:03:10,482
With small
Production quantities,
41
00:03:10,482 --> 00:03:14,620
This facility is able to
Assemble each motor by hand.
42
00:03:14,620 --> 00:03:19,241
The gears used in the motors
Are made of a variety of metals
43
00:03:19,241 --> 00:03:21,137
To account for
Different requirements
44
00:03:21,137 --> 00:03:26,000
Of torque and loading force
Within the device.
45
00:03:26,000 --> 00:03:28,344
Moving with speed and precision,
46
00:03:28,344 --> 00:03:31,103
Specialists are able
To assemble each motor
47
00:03:31,103 --> 00:03:32,620
In less than 10 minutes.
48
00:03:36,137 --> 00:03:39,034
Next, the tiny control unit
Is installed.
49
00:03:39,034 --> 00:03:42,344
That will allow the user
To manipulate the robot.
50
00:03:42,344 --> 00:03:44,448
The technician
Carefully attaches
51
00:03:44,448 --> 00:03:47,758
The bottom portion of the unit
Inside the motor container
52
00:03:47,758 --> 00:03:52,551
With a small cordless drill.
53
00:03:52,551 --> 00:03:54,862
Once the unit is firmly secured,
54
00:03:54,862 --> 00:03:57,655
He expertly positions
The wire leads
55
00:03:57,655 --> 00:04:03,551
To prepare them
For the next step.
56
00:04:03,551 --> 00:04:09,689
A technician quickly
Solders the wires in place.
57
00:04:09,689 --> 00:04:13,586
Now that the installation of
The control panel is complete,
58
00:04:13,586 --> 00:04:17,000
A technician finalizes
The d.C. Motor assembly
59
00:04:17,000 --> 00:04:18,689
By attaching the cover
60
00:04:18,689 --> 00:04:21,206
And securing it down
With four screws
61
00:04:21,206 --> 00:04:22,724
Using a cordless drill.
62
00:04:28,344 --> 00:04:30,379
Next, the individual motors
63
00:04:30,379 --> 00:04:35,103
Are installed into
The framework of the robot.
64
00:04:35,103 --> 00:04:37,827
One motor becomes
The robot's head,
65
00:04:37,827 --> 00:04:41,172
While the remaining motors
Are attached to hinged joints
66
00:04:41,172 --> 00:04:45,724
That correspond
To a major body part.
67
00:04:45,724 --> 00:04:48,655
Then the robot's wiring
Is plugged in,
68
00:04:48,655 --> 00:04:52,862
Ensuring the motors
Are connected to each other.
69
00:04:52,862 --> 00:04:55,379
They now form parts
Of an integrated device
70
00:04:55,379 --> 00:04:59,103
Which can act together.
71
00:04:59,103 --> 00:05:02,206
Technicians use a 3-d printer
72
00:05:02,206 --> 00:05:04,862
To create a suit of armor
For the robot,
73
00:05:04,862 --> 00:05:08,827
Which they mount on its exterior
To give it a more finished look.
74
00:05:13,758 --> 00:05:16,896
A specialist plugs the robots
Into a computer
75
00:05:16,896 --> 00:05:19,689
And programs
Their different movements.
76
00:05:19,689 --> 00:05:23,517
The robot tech communicates
With the robot's control panel
77
00:05:23,517 --> 00:05:26,206
To make it do remarkable things.
78
00:05:26,206 --> 00:05:29,344
But first, an old-fashioned
Rock 'em sock 'em
79
00:05:29,344 --> 00:05:33,103
Before they take over the world.
80
00:05:45,413 --> 00:05:48,068
Narrator: when professional
Boxers win a title,
81
00:05:48,068 --> 00:05:49,344
They're crowned the champ
82
00:05:49,344 --> 00:05:52,413
And rewarded with a belt
To be worn around the waist.
83
00:05:52,413 --> 00:05:55,413
Each international organization
Commissions a belt
84
00:05:55,413 --> 00:05:58,344
That's custom-designed
To its specifications
85
00:05:58,344 --> 00:06:01,448
And prominently features
The organization's logo
86
00:06:01,448 --> 00:06:05,448
In the belt's central medallion.
87
00:06:05,448 --> 00:06:09,413
These boxing championship belts
Are entirely handcrafted.
88
00:06:09,413 --> 00:06:13,620
The laterals, the side pieces
Flanking the ornate centerplate,
89
00:06:13,620 --> 00:06:17,827
Are sometimes engraved
With a fighter's portrait.
90
00:06:17,827 --> 00:06:21,172
When a boxing association
Commissions a new design,
91
00:06:21,172 --> 00:06:25,517
The company's artisans prepare
A sketch for each piece.
92
00:06:25,517 --> 00:06:28,965
Following the sketch,
They sculpt a clay model.
93
00:06:28,965 --> 00:06:32,620
From that,
They cast a plaster model,
94
00:06:32,620 --> 00:06:34,655
Then a metal model,
95
00:06:34,655 --> 00:06:37,931
Refining the sculpture
At each step.
96
00:06:37,931 --> 00:06:40,413
Artisans use
The final metal model
97
00:06:40,413 --> 00:06:42,206
To produce a rubber mold,
98
00:06:42,206 --> 00:06:47,379
Which is used to cast the piece
In white metal.
99
00:06:47,379 --> 00:06:49,965
The extracted castings
Are quite rough,
100
00:06:49,965 --> 00:06:52,034
So the workshop's craftsmen
101
00:06:52,034 --> 00:06:55,034
Use files, chisels,
And automated tools
102
00:06:55,034 --> 00:06:58,793
To refine the shape.
103
00:06:58,793 --> 00:07:00,896
Some of the devices
And techniques
104
00:07:00,896 --> 00:07:03,620
Are routinely used by jewelers,
105
00:07:03,620 --> 00:07:07,586
While others were designed
Specifically for this purpose.
106
00:07:16,379 --> 00:07:19,068
Once the intricate details
Are completed,
107
00:07:19,068 --> 00:07:22,310
The team files down rough spots
Along the perimeter.
108
00:07:27,310 --> 00:07:28,586
The belts feature
109
00:07:28,586 --> 00:07:30,896
A three-dimensional sculpture
Of an eagle
110
00:07:30,896 --> 00:07:34,241
Fused to the centerplate.
111
00:07:34,241 --> 00:07:37,103
An artisan heats the wings
With an open flame
112
00:07:37,103 --> 00:07:41,310
To make them pliable.
113
00:07:41,310 --> 00:07:44,689
Then he bends them to render
The eagle more lifelike.
114
00:07:50,620 --> 00:07:54,172
Every piece must be
Meticulously hand-polished
115
00:07:54,172 --> 00:07:55,620
On a buffing wheel.
116
00:07:55,620 --> 00:07:59,620
This prepares the metal to be
Plated with gold or rhodium.
117
00:08:06,448 --> 00:08:09,034
The piece is electroplated
With copper,
118
00:08:09,034 --> 00:08:12,482
Then nickel, then 18-karat gold.
119
00:08:12,482 --> 00:08:19,413
The nickel carries the shine
Through to the surface.
120
00:08:19,413 --> 00:08:21,931
After a thorough buffing
On the surface,
121
00:08:21,931 --> 00:08:26,275
The pieces are embellished with
Crystals into molded cavities.
122
00:08:30,517 --> 00:08:33,137
Sometimes
The championship winner
123
00:08:33,137 --> 00:08:36,965
May order precious stones
Such as diamonds and rubies
124
00:08:36,965 --> 00:08:43,344
To replace the crystals,
Depending on their preference.
125
00:08:43,344 --> 00:08:46,482
A team of enamelers
Paints the finished pieces
126
00:08:46,482 --> 00:08:49,344
With jewelry-grade enamel.
127
00:08:49,344 --> 00:08:57,344
This requires a steady hand
And close attention to detail.
128
00:08:57,344 --> 00:08:59,034
Once the piece is painted,
129
00:08:59,034 --> 00:09:02,379
It's put into an oven
To bake the enamel.
130
00:09:13,827 --> 00:09:17,172
The belt strap is made
Of high-grade bonded leather.
131
00:09:17,172 --> 00:09:20,344
A craftsman traces
A belt template in the leather,
132
00:09:20,344 --> 00:09:22,724
Then cuts it out with a knife.
133
00:09:22,724 --> 00:09:27,275
Then they adhere the strap
To leather or high-grade vinyl.
134
00:09:27,275 --> 00:09:30,241
The designer sews
The strap's lining separately,
135
00:09:30,241 --> 00:09:33,827
Stitching black spandex
Over a faux-fur backing
136
00:09:33,827 --> 00:09:36,689
And attaching
The authenticity label
137
00:09:36,689 --> 00:09:39,655
Which bears
The belt's serial number.
138
00:09:39,655 --> 00:09:43,379
This distinguishes it
From cheaply made copies.
139
00:09:43,379 --> 00:09:46,724
The craftsman attaches
Leather/high-grade vinyl piping
140
00:09:46,724 --> 00:09:48,206
To the strap perimeter.
141
00:09:48,206 --> 00:09:50,689
He places a brand sticker
On the back
142
00:09:50,689 --> 00:09:52,241
Next to an inscribed tribute
143
00:09:52,241 --> 00:09:56,206
To the originator
Of the modern boxing belt.
144
00:09:56,206 --> 00:10:01,172
They adhere the lining.
145
00:10:01,172 --> 00:10:03,758
Then, after smoothing out
The layers of the belt
146
00:10:03,758 --> 00:10:05,000
With a hammer,
147
00:10:05,000 --> 00:10:08,551
The designer stitches
The lining to the strap.
148
00:10:08,551 --> 00:10:12,758
Some belts have buckles,
Others hook-and-loop fasteners,
149
00:10:12,758 --> 00:10:20,206
Which are stitched to the strap
At the same time as the lining.
150
00:10:20,206 --> 00:10:21,931
Once the belt is finished,
151
00:10:21,931 --> 00:10:24,724
The centerplate and laterals
Are attached.
152
00:10:24,724 --> 00:10:27,724
It's essential to wear gloves
While doing this
153
00:10:27,724 --> 00:10:33,241
To protect the pristine surface.
154
00:10:33,241 --> 00:10:36,551
The final step is to place
An engravable brass plate
155
00:10:36,551 --> 00:10:38,068
Into each lateral.
156
00:10:38,068 --> 00:10:40,896
Then the championship belt
Is delivered
157
00:10:40,896 --> 00:10:43,620
In a hand-crafted
Protective case
158
00:10:43,620 --> 00:10:46,172
For a knockout presentation.
159
00:10:55,655 --> 00:10:57,758
Narrator:
Radar helps sailors navigate
160
00:10:57,758 --> 00:11:00,137
Through inclement weather
While on the water,
161
00:11:00,137 --> 00:11:03,068
Ensuring they aren't
Operating blind.
162
00:11:03,068 --> 00:11:05,103
These specialized
Pedestal mounts
163
00:11:05,103 --> 00:11:06,689
Elevate the radar systems,
164
00:11:06,689 --> 00:11:09,379
Which maximize
The antenna's range.
165
00:11:09,379 --> 00:11:11,793
The mounts also provide
Equipment stability
166
00:11:11,793 --> 00:11:16,827
While traveling over
Rough waters.
167
00:11:16,827 --> 00:11:20,034
Boat-radar mounts are one
Of the most critical pieces
168
00:11:20,034 --> 00:11:24,241
Of navigation equipment
To have on deck.
169
00:11:24,241 --> 00:11:25,620
Radar-mount construction
170
00:11:25,620 --> 00:11:28,827
Begins with
A computer-generated drawing
171
00:11:28,827 --> 00:11:33,275
That specifies the height
And angle of the tower.
172
00:11:33,275 --> 00:11:36,689
The parts are made from
Extruded marine-grade aluminum.
173
00:11:36,689 --> 00:11:40,275
A machinist clamps
The first top plate in a jig
174
00:11:40,275 --> 00:11:45,344
And sets the tower upside down
On the top plate.
175
00:11:45,344 --> 00:11:47,620
The jig holds
The tower in position
176
00:11:47,620 --> 00:11:50,482
As he tack-welds
The assembly in place.
177
00:11:56,172 --> 00:11:58,827
After clamping side gussets
To the tower,
178
00:11:58,827 --> 00:12:01,310
The technician turns it
Right-side up
179
00:12:01,310 --> 00:12:04,000
And inserts the bottom tabs
In a baseplate
180
00:12:04,000 --> 00:12:06,275
To position it for assembly.
181
00:12:06,275 --> 00:12:07,862
Using an angle ruler,
182
00:12:07,862 --> 00:12:13,206
He confirms that the tower
Stands at 90 degrees.
183
00:12:13,206 --> 00:12:15,586
Then he welds
The radar-equipment tower
184
00:12:15,586 --> 00:12:21,206
To the base.
185
00:12:21,206 --> 00:12:23,241
He sets the tower on its side
186
00:12:23,241 --> 00:12:25,931
To measure locations
For tack welds,
187
00:12:25,931 --> 00:12:30,344
Marking each with a pen.
188
00:12:30,344 --> 00:12:33,965
Next, he makes larger
Stitch welds intermittently.
189
00:12:33,965 --> 00:12:36,482
This will secure the gussets
To the tower.
190
00:12:40,172 --> 00:12:43,103
The machinist installs
A gusset arm or bracket
191
00:12:43,103 --> 00:12:46,172
In the middle
Of the radar tower.
192
00:12:48,931 --> 00:12:51,241
Using a metal puck as a guide,
193
00:12:51,241 --> 00:12:57,310
He centers another top plate
On the gusset arm.
194
00:12:57,310 --> 00:13:00,137
He clamps it
And measures its placement
195
00:13:00,137 --> 00:13:02,241
To verify that
It's properly centered,
196
00:13:02,241 --> 00:13:03,896
And welds it to the arm.
197
00:13:11,310 --> 00:13:12,827
He removes the puck
198
00:13:12,827 --> 00:13:18,758
And installs another
Mounting arm at the base.
199
00:13:18,758 --> 00:13:21,275
A computerized drill
Cuts bolt holes
200
00:13:21,275 --> 00:13:23,068
In a radar-mounting plate.
201
00:13:23,068 --> 00:13:27,000
Radar-bolting patterns vary,
So it configures them
202
00:13:27,000 --> 00:13:31,793
To match up with
A specific radar system.
203
00:13:31,793 --> 00:13:33,827
Once the bolt holes are placed,
204
00:13:33,827 --> 00:13:37,000
The drill carves around
The border of the plate,
205
00:13:37,000 --> 00:13:42,103
Reshaping it
From square to round.
206
00:13:42,103 --> 00:13:44,344
The circular profile
Will match the base
207
00:13:44,344 --> 00:13:49,068
Of the satellite-radar system.
208
00:13:49,068 --> 00:13:51,655
In a process known
As countersinking,
209
00:13:51,655 --> 00:13:53,689
He bevels the rims
Of the bolt holes
210
00:13:53,689 --> 00:13:55,689
To a graduated profile.
211
00:13:55,689 --> 00:13:58,103
This method will provide
A stronger connection
212
00:13:58,103 --> 00:14:02,137
Between the mounting platform
And the radar system.
213
00:14:02,137 --> 00:14:04,103
With a special deburring tool,
214
00:14:04,103 --> 00:14:05,379
The technician removes
215
00:14:05,379 --> 00:14:09,103
Sharp edges left by
The countersinking process.
216
00:14:09,103 --> 00:14:11,862
He smooths the outer edges
Of the mounting plate
217
00:14:11,862 --> 00:14:16,310
Using a hand sander.
218
00:14:16,310 --> 00:14:18,517
The mounting plate
Is placed in a tub
219
00:14:18,517 --> 00:14:22,551
Of vibrating ceramic stones
Mixed with water.
220
00:14:22,551 --> 00:14:25,172
The friction removes
Any lingering imperfections
221
00:14:25,172 --> 00:14:27,724
And sharp edges.
222
00:14:27,724 --> 00:14:30,206
Another technician
Cuts aluminum wings
223
00:14:30,206 --> 00:14:32,241
For an accessory extension.
224
00:14:32,241 --> 00:14:35,000
The extension could hold
A number of accessories,
225
00:14:35,000 --> 00:14:38,758
Including a radio, gps antenna,
Or deck lights.
226
00:14:38,758 --> 00:14:42,655
The parts are hollow
In order to house wiring.
227
00:14:42,655 --> 00:14:46,896
The wings will be assembled
To a center trunk.
228
00:14:46,896 --> 00:14:50,275
But first, they cap one end
Of each wing.
229
00:14:50,275 --> 00:14:52,586
This wing will contain wiring
230
00:14:52,586 --> 00:14:55,482
Snaked through from holes
In the sides of the trunk.
231
00:14:59,896 --> 00:15:04,655
The technician welds a wing
To each side of the trunk.
232
00:15:04,655 --> 00:15:08,344
This step completes the
Accessory-extension structure.
233
00:15:13,275 --> 00:15:19,172
Next, it's time to build an arm
For a navigation light.
234
00:15:19,172 --> 00:15:23,172
A hydraulic press bends the arm
To the desired curvature.
235
00:15:23,172 --> 00:15:28,137
A measuring tool indicates
The angle of the bend.
236
00:15:28,137 --> 00:15:34,310
The technician drills a hole for
The installation of the light.
237
00:15:34,310 --> 00:15:37,862
After a powder-coat finish has
Been applied to all the parts,
238
00:15:37,862 --> 00:15:42,517
The mount is ready
For assembly on the boat.
239
00:15:44,896 --> 00:15:47,896
By using critical
Navigational equipment,
240
00:15:47,896 --> 00:15:50,413
This boat-radar mount
Will ensure
241
00:15:50,413 --> 00:15:54,137
That any boater will be able
To find their bearings.
242
00:16:06,965 --> 00:16:10,758
Narrator: european radiators
Exude both warmth and style.
243
00:16:10,758 --> 00:16:12,620
The heating-tube technology
244
00:16:12,620 --> 00:16:16,448
Can be modified for electric
Or hot-water heating systems
245
00:16:16,448 --> 00:16:19,137
And can be made
In a range of designs.
246
00:16:19,137 --> 00:16:22,034
These radiators can
Blend into a background
247
00:16:22,034 --> 00:16:25,965
Or stand out to make a statement
On the wall.
248
00:16:29,034 --> 00:16:32,689
This european-style radiator
Is typically mounted to a wall
249
00:16:32,689 --> 00:16:35,034
So it doesn't
Take up floor space,
250
00:16:35,034 --> 00:16:39,172
Allowing more room
For furniture and people.
251
00:16:39,172 --> 00:16:45,827
Making panel radiators
Starts with steel flat tubes.
252
00:16:45,827 --> 00:16:47,448
Using a circular saw,
253
00:16:47,448 --> 00:16:51,931
The machine cuts
A stack of the tubes to length.
254
00:16:51,931 --> 00:16:53,965
These flat tubes
Will be held together
255
00:16:53,965 --> 00:16:56,862
By struts known as headers.
256
00:16:56,862 --> 00:17:02,931
An automated drill punches holes
For bushings into the ends.
257
00:17:02,931 --> 00:17:04,241
At the next station,
258
00:17:04,241 --> 00:17:06,862
A machine inserts bushings
Into the holes
259
00:17:06,862 --> 00:17:08,379
And welds them together.
260
00:17:11,896 --> 00:17:13,517
Another welding device
261
00:17:13,517 --> 00:17:17,862
Seals the ends
Of the flat heating tubes.
262
00:17:17,862 --> 00:17:20,103
The tubes are stacked.
263
00:17:24,896 --> 00:17:27,655
Meanwhile, technicians
Prepare the headers,
264
00:17:27,655 --> 00:17:30,689
Which are made
Of square steel tubes.
265
00:17:30,689 --> 00:17:34,206
An automated machine punches
Holes in the headers.
266
00:17:34,206 --> 00:17:40,310
These holes will allow hot water
To flow throughout the radiator.
267
00:17:40,310 --> 00:17:44,034
A circular saw cuts the header
To its specified length.
268
00:17:44,034 --> 00:17:46,137
Most radiators are custom-made,
269
00:17:46,137 --> 00:17:47,689
And sizes are determined
270
00:17:47,689 --> 00:17:51,379
By the heating requirements
Of the space.
271
00:17:51,379 --> 00:17:54,275
The headers are equipped
With endcaps and fittings
272
00:17:54,275 --> 00:17:57,896
To supply water and vent air.
273
00:17:57,896 --> 00:18:02,034
A technician inserts the caps
Into the ends of the header tube
274
00:18:02,034 --> 00:18:05,344
And hammers them down.
275
00:18:08,827 --> 00:18:11,103
He clamps several
Of the capped headers
276
00:18:11,103 --> 00:18:13,586
In a fixture.
277
00:18:17,000 --> 00:18:19,275
The fixture
Holds them in position
278
00:18:19,275 --> 00:18:24,448
As an automated welder joins
The caps to the headers.
279
00:18:27,931 --> 00:18:29,310
Here is the header tubing
280
00:18:29,310 --> 00:18:32,344
Before and after
The holes were punched
281
00:18:32,344 --> 00:18:37,034
And the endcaps were welded.
282
00:18:37,034 --> 00:18:39,724
With the header clamped
Into another fixture,
283
00:18:39,724 --> 00:18:44,344
A drill carves a threaded
Connector into the side.
284
00:18:44,344 --> 00:18:47,413
This connector will be used
To plumb the radiator
285
00:18:47,413 --> 00:18:50,000
To the hot-water system.
286
00:18:53,034 --> 00:18:56,517
It's now time to build
The grid of heating tubes.
287
00:18:56,517 --> 00:18:59,827
First, a machine moves
The header into position.
288
00:18:59,827 --> 00:19:03,000
An automated arm slides
The flat heating tube
289
00:19:03,000 --> 00:19:05,137
Into place on the header,
290
00:19:05,137 --> 00:19:08,896
And a welding device
Joins them together.
291
00:19:08,896 --> 00:19:10,310
The automated welder
292
00:19:10,310 --> 00:19:13,413
Installs flat tubes
On each side of the headers
293
00:19:13,413 --> 00:19:18,034
And applies the company logo.
294
00:19:18,034 --> 00:19:19,793
Strips of steel will be used
295
00:19:19,793 --> 00:19:22,931
To make fins
That direct heat upward.
296
00:19:25,827 --> 00:19:29,034
A machine punches a series
Of notches in the steel
297
00:19:29,034 --> 00:19:33,655
To mount the fins to the back
Of the radiator.
298
00:19:33,655 --> 00:19:36,310
A hydraulic press bends
The notched steel,
299
00:19:36,310 --> 00:19:40,103
Creating
An accordion-like profile.
300
00:19:40,103 --> 00:19:42,827
These ridges create pockets
301
00:19:42,827 --> 00:19:48,551
That will capture hot air
And allow it to rise.
302
00:19:48,551 --> 00:19:51,034
The fins coil up
At the end of the line
303
00:19:51,034 --> 00:19:55,689
For easy transfer
To the next station.
304
00:19:55,689 --> 00:19:57,862
At this point,
All the flat tubes
305
00:19:57,862 --> 00:20:00,448
Have been fully assembled
To the headers.
306
00:20:00,448 --> 00:20:02,068
An operator places the fins,
307
00:20:02,068 --> 00:20:04,551
Which have been cut
To a specified length,
308
00:20:04,551 --> 00:20:06,896
On the back
Of the flat-tube grid.
309
00:20:06,896 --> 00:20:09,827
A machine welds the fins
To the heating tubes
310
00:20:09,827 --> 00:20:12,275
Between the folds.
311
00:20:12,275 --> 00:20:14,310
This step produces
A heating panel
312
00:20:14,310 --> 00:20:19,241
That will radiate heat
Up and out.
313
00:20:19,241 --> 00:20:21,620
Another team member
Installs metal trim
314
00:20:21,620 --> 00:20:24,034
On the top of the radiator.
315
00:20:24,034 --> 00:20:26,413
He places mounts
On the back corners
316
00:20:26,413 --> 00:20:29,034
And welds them together.
317
00:20:29,034 --> 00:20:31,344
These mounts will house
Threaded bolts,
318
00:20:31,344 --> 00:20:35,379
Which will be used to level
The radiator to the wall.
319
00:20:35,379 --> 00:20:38,551
The radiator is now
Fully assembled.
320
00:20:38,551 --> 00:20:41,827
The radiator undergoes
A quality-control test.
321
00:20:41,827 --> 00:20:45,275
Technicians pump in air
And submerge it in water.
322
00:20:45,275 --> 00:20:48,655
If bubbles appear,
It indicates a leak.
323
00:20:48,655 --> 00:20:53,965
If not, the radiator is removed
From the water.
324
00:20:53,965 --> 00:20:56,620
Electrostatically charged
Epoxy particles
325
00:20:56,620 --> 00:20:58,655
Are sprayed onto the device,
326
00:20:58,655 --> 00:21:01,241
Which provide
A protective layer.
327
00:21:01,241 --> 00:21:04,206
This european-style radiator
Is now ready
328
00:21:04,206 --> 00:21:06,206
To release some major heat.
