1
00:00:52,653 --> 00:00:54,620
A hammer is an all-purpose tool
2
00:00:54,622 --> 00:00:57,355
most commonly used to strike nails.
3
00:00:57,357 --> 00:01:00,259
Some hammers are designed for a specific purpose
4
00:01:00,261 --> 00:01:03,662
such as woodworking,metalworking, and masonry.
5
00:01:03,664 --> 00:01:08,133
Professional craftspeople often
forego mass-produced tools
6
00:01:08,135 --> 00:01:13,272
and invest in high-quality
hand-forged hammers.
7
00:01:13,274 --> 00:01:17,342
The steel head of this hammer
was forged by a blacksmith.
8
00:01:17,344 --> 00:01:20,813
This is just one out of
40 different styles of hammers
9
00:01:20,815 --> 00:01:24,383
made by a blacksmith.
10
00:01:24,385 --> 00:01:26,418
Using a metal-cutting band saw,
11
00:01:26,420 --> 00:01:29,888
a blacksmith cuts a piece
of cylindrical steel
12
00:01:29,890 --> 00:01:31,690
he makes the cut slightly larger
13
00:01:31,692 --> 00:01:35,794
than the final hammerhead size.
14
00:01:35,796 --> 00:01:38,997
Next, he burns small amount of
paper on coals
15
00:01:38,999 --> 00:01:41,333
in a cast steel pot.
16
00:01:41,335 --> 00:01:43,635
A fan,
located underneath the coals
17
00:01:43,637 --> 00:01:45,804
blows air upward
to stoke the fire.
18
00:01:47,641 --> 00:01:49,808
Once the coals are hot,
19
00:01:49,810 --> 00:01:56,248
the craftsman immerses
the steel piece in the fire.
20
00:01:56,250 --> 00:01:58,283
Once the steel is
glowing bright red,
21
00:01:58,285 --> 00:02:02,454
he removes the piece with from
the fire with tongs.
22
00:02:02,456 --> 00:02:05,557
He begins striking it with a
mechanical forging hammer
23
00:02:05,559 --> 00:02:08,961
operated by a foot pedal.
24
00:02:08,963 --> 00:02:12,397
Throughout the forging process
the steel is reheated
25
00:02:12,399 --> 00:02:13,832
to keep it formable.
26
00:02:13,834 --> 00:02:15,434
The craftsman lowers the pedal,
27
00:02:15,436 --> 00:02:17,736
which activates
the machine's hammer.
28
00:02:17,738 --> 00:02:19,471
As the hammer strikes,
29
00:02:19,473 --> 00:02:22,641
the craftsman turns
the cylindrical piece of steel
30
00:02:22,643 --> 00:02:25,744
to flatten the sides
and shape it into a block.
31
00:02:29,350 --> 00:02:31,116
using a specialized tool,
32
00:02:31,118 --> 00:02:34,686
he makes a punch on
the block to form a channel.
33
00:02:34,688 --> 00:02:36,722
He flips the block
and punches out
34
00:02:36,724 --> 00:02:39,992
the compressed steel
to create a hole.
35
00:02:39,994 --> 00:02:44,830
This hole is
the eye of the hammer.
36
00:02:44,832 --> 00:02:48,967
Next, the craftsman uses a tool
called a spring swage
37
00:02:48,969 --> 00:02:50,569
to flatten one end of the block
38
00:02:50,571 --> 00:02:55,107
into the wedge-shaped end of
the hammer known as the peen.
39
00:02:55,109 --> 00:02:58,177
Each side of the peen is shaped
against the grinding wheel
40
00:02:58,179 --> 00:03:02,080
to even out the surface.
41
00:03:02,082 --> 00:03:03,649
Working on an anvil,
42
00:03:03,651 --> 00:03:06,518
the craftsman flattens the block
with a handheld hammer.
43
00:03:10,391 --> 00:03:12,257
then, with a tool
called a flatter.
44
00:03:20,100 --> 00:03:22,801
he uses an
oval eye-contouring tool
45
00:03:22,803 --> 00:03:25,170
to hammer a hole
to form the eye.
46
00:03:28,909 --> 00:03:33,412
now complete, the craftsman
polishes the hammerhead
47
00:03:33,414 --> 00:03:35,547
on a series of grinding belts.
48
00:03:38,719 --> 00:03:41,386
then the hammerhead is placed
back into the fire
49
00:03:41,388 --> 00:03:42,654
for more reheating.
50
00:03:46,427 --> 00:03:49,294
back on the anvil,
he uses a wire brush
51
00:03:49,296 --> 00:03:54,199
to remove scale
caused by oxidation.
52
00:03:54,201 --> 00:03:56,368
Then brands
the steel with his name.
53
00:04:00,574 --> 00:04:02,841
after heat treating both
ends of the hammerhead,
54
00:04:02,843 --> 00:04:05,944
to harden the steel at
the striking surfaces,
55
00:04:05,946 --> 00:04:09,147
he finishes off the metalwork
with a die grinder,
56
00:04:09,149 --> 00:04:11,583
smoothing the sharp
edges around the eye
57
00:04:11,585 --> 00:04:13,018
and forming a bevel.
58
00:04:18,158 --> 00:04:21,693
once complete, the craftsman
moves on to the wooden handle.
59
00:04:21,695 --> 00:04:23,228
He shapes a block of wood,
60
00:04:23,230 --> 00:04:25,998
often using hickory,
with an angle grinder.
61
00:04:29,003 --> 00:04:31,970
using the grinding wheel,
he shaves off the top
62
00:04:31,972 --> 00:04:33,939
to fit in
the eye of the hammerhead.
63
00:04:39,713 --> 00:04:43,415
with a band saw, he makes
a 2-inch cut into the wood.
64
00:04:49,957 --> 00:04:52,457
he cuts a wedge out of
a softer type of wood,
65
00:04:52,459 --> 00:04:53,592
usually pine.
66
00:04:58,332 --> 00:05:01,800
he marks the diameter
of the eye on the wedge
67
00:05:01,802 --> 00:05:03,869
then sands off the excess wood
68
00:05:03,871 --> 00:05:05,804
so that the wedge
will fit in the eye.
69
00:05:09,410 --> 00:05:11,710
he inserts the split
end of the wood handle
70
00:05:11,712 --> 00:05:15,180
in the eye, forcing it through.
71
00:05:15,182 --> 00:05:17,983
Then he hammers
the wedge into the split.
72
00:05:17,985 --> 00:05:20,419
This pushes
the two sides of the split
73
00:05:20,421 --> 00:05:25,357
in opposite directions,
lodging the handle in the eye.
74
00:05:25,359 --> 00:05:28,160
Next, the craftsman hammers in
a hollow round steel wedge
75
00:05:28,162 --> 00:05:30,629
until it's flush
with the hammerhead.
76
00:05:30,631 --> 00:05:33,965
This wedge spreads the wood
in different directions,
77
00:05:33,967 --> 00:05:37,436
locking in the handle.
78
00:05:37,438 --> 00:05:40,172
He removes excess wood
with an angle grinder
79
00:05:40,174 --> 00:05:42,874
until the top of
the hammer is level and smooth.
80
00:05:46,447 --> 00:05:49,181
finally,
this handmade tool is ready
81
00:05:49,183 --> 00:05:52,517
to make it's contribution
to hand craftsmanship.
82
00:06:05,566 --> 00:06:08,967
narrator:
Gummy vitamins were invented
in the late the 20th century
83
00:06:08,969 --> 00:06:10,836
by an couple
looking for a way
84
00:06:10,838 --> 00:06:14,272
to entice their daughter
to take her vitamins.
85
00:06:14,274 --> 00:06:16,908
Infused into a gummy candy,
86
00:06:16,910 --> 00:06:19,878
vitamins are now a sweet
and chewy experience
87
00:06:19,880 --> 00:06:24,416
for both kids and adults.
88
00:06:26,620 --> 00:06:28,320
just like gummy candies,
89
00:06:28,322 --> 00:06:32,324
gummy vitamins come in a variety
of sweet, fruity flavors,
90
00:06:32,326 --> 00:06:36,194
making a vitamin
a less bitter pill to swallow.
91
00:06:37,131 --> 00:06:40,699
Each gummy vitamin starts
with a specific formula.
92
00:06:40,701 --> 00:06:43,969
First raw ingredients are
selected and weighed.
93
00:06:43,971 --> 00:06:48,039
Some are in liquid form
and others are solids.
94
00:06:48,041 --> 00:06:51,843
The nutritional ingredients
are blended with water.
95
00:06:51,845 --> 00:06:55,480
This particular batch is
a multivitamin preparation.
96
00:06:55,482 --> 00:06:58,817
It includes magnesium,
calcium, and other minerals.
97
00:07:02,256 --> 00:07:05,724
in a separate tank, technicians
prepare the gelatin base
98
00:07:05,726 --> 00:07:10,328
which gives the vitamins
a jelly-like consistency.
99
00:07:10,330 --> 00:07:14,432
Next, sugar and gelatin pre-mix
is poured into the tank.
100
00:07:17,938 --> 00:07:20,238
the technician
adds a sugar substitute
101
00:07:20,240 --> 00:07:22,941
to the other ingredients.
102
00:07:22,943 --> 00:07:26,077
Meanwhile, specific amounts of
water and glucose
103
00:07:26,079 --> 00:07:27,879
are dispensed into the tank.
104
00:07:30,217 --> 00:07:31,483
it takes about five minutes
105
00:07:31,485 --> 00:07:36,154
to blend the ingredients
for the gelatin base.
106
00:07:36,156 --> 00:07:38,190
Then, the gummy vitamin base
107
00:07:38,192 --> 00:07:41,159
is transferred to
a large holding tank.
108
00:07:41,161 --> 00:07:44,596
In the lab, the nutritional
mixture is tested
109
00:07:44,598 --> 00:07:50,068
for contaminants such as
heavy metals and bacteria.
110
00:07:50,070 --> 00:07:54,172
An automated syringe injects
the solutions into test tubes
111
00:07:54,174 --> 00:07:59,344
rinsing inbetween injections.
112
00:07:59,346 --> 00:08:03,482
Now the samples in the test
tubes are ready to be analyzed.
113
00:08:03,484 --> 00:08:05,016
For heavy metal testing,
114
00:08:05,018 --> 00:08:10,121
the sample is injected into an
extremely hot vacuum chamber.
115
00:08:10,123 --> 00:08:13,992
The plasma flame turns the metal
contaminants into atoms,
116
00:08:13,994 --> 00:08:16,695
which the machine
reads as different colors.
117
00:08:16,697 --> 00:08:23,702
The machine also identifies
and quantifies contaminants.
118
00:08:23,704 --> 00:08:25,871
With the samples
cleared for processing,
119
00:08:25,873 --> 00:08:31,142
they're ready
for flavoring and colorant.
120
00:08:31,144 --> 00:08:33,278
More vitamins are added
in powder form
121
00:08:33,280 --> 00:08:37,449
to boost the formula's potency.
122
00:08:37,451 --> 00:08:41,152
The liquid vitamin preparation
and the gelatin base
123
00:08:41,154 --> 00:08:42,854
is piped into the mixing tank
124
00:08:42,856 --> 00:08:47,759
then, everything
is blended together.
125
00:08:47,761 --> 00:08:49,661
The batter is now ready
to be made
126
00:08:49,663 --> 00:08:53,598
into thousands of gummy
vitamins.
127
00:08:53,600 --> 00:08:56,635
A conveyor queues up
the vitamin molds.
128
00:08:56,637 --> 00:08:59,671
Multiple nozzles deposit
precise amounts of batter
129
00:08:59,673 --> 00:09:03,775
into small molds.
130
00:09:03,777 --> 00:09:06,044
The conveyor moves
the tray forward
131
00:09:06,046 --> 00:09:10,282
as the gummy vitamins
begin to solidify.
132
00:09:10,284 --> 00:09:14,786
A robotic arm stacks the mold
trays in a holding area.
133
00:09:14,788 --> 00:09:20,625
The arm gently lowers
the trays into place.
134
00:09:20,627 --> 00:09:22,260
For several hours,
135
00:09:22,262 --> 00:09:25,096
the pills continue to
harden in the molds.
136
00:09:25,098 --> 00:09:26,765
Once completely solidified,
137
00:09:26,767 --> 00:09:29,734
the gummy vitamins
are removed from the molds
138
00:09:29,736 --> 00:09:32,404
and transferred
into a revolving drum.
139
00:09:32,406 --> 00:09:34,906
The tumble in
the drum separates them.
140
00:09:34,908 --> 00:09:37,142
They exit onto
a perforated conveyor
141
00:09:37,144 --> 00:09:40,111
and any small bits
fall through the holes.
142
00:09:40,113 --> 00:09:42,547
The conveyor zigzags
back and forth,
143
00:09:42,549 --> 00:09:47,485
allowing the gummy vitamins
to cool and further solidify.
144
00:09:47,487 --> 00:09:50,789
The gummy vitamins have now
reached their final consistency.
145
00:09:54,061 --> 00:09:56,728
The gummy vitamins head into
a steam chamber.
146
00:09:56,730 --> 00:09:58,463
The humidity from the steam
147
00:09:58,465 --> 00:10:01,099
preps the vitamins
for sugarcoating.
148
00:10:01,101 --> 00:10:03,602
The sugar clings to
the gummy vitamins.
149
00:10:03,604 --> 00:10:07,739
And the revolving action of
the drum shakes off any excess,
150
00:10:07,741 --> 00:10:12,711
leaving just a dusting
on the surface.
151
00:10:12,713 --> 00:10:16,381
At the packaging station,
the vitamins funnel into chutes
152
00:10:16,383 --> 00:10:23,054
where sensors count and release
the pills into bottles.
153
00:10:23,056 --> 00:10:28,660
As the bottles move forward,
caps land on the rims.
154
00:10:28,662 --> 00:10:32,831
And spinning rubber mechanisms
screw the caps on tightly.
155
00:10:32,833 --> 00:10:35,634
Down the line,
labels with product information
156
00:10:35,636 --> 00:10:42,207
are placed onto each bottle.
157
00:10:42,209 --> 00:10:45,443
Depending on the formulation,
it can take up to three weeks
158
00:10:45,445 --> 00:10:48,913
to produce gummy vitamin pills
and the result?
159
00:10:48,915 --> 00:10:52,050
Nutritious gumdrops
that are a real treat.
160
00:11:08,001 --> 00:11:10,435
Before you can take
a boat out on the water,
161
00:11:10,437 --> 00:11:14,205
you have to transport it
to the water.
162
00:11:14,207 --> 00:11:17,008
A boat trailer attaches to
the rear of your vehicle
163
00:11:17,010 --> 00:11:18,977
with a trailer hitch.
164
00:11:18,979 --> 00:11:21,012
You back the trailer
into the water
165
00:11:21,014 --> 00:11:24,215
then release the boat
and let it float away freely.
166
00:11:27,587 --> 00:11:31,056
a boat trailer has either
a quick-release latch system
167
00:11:31,058 --> 00:11:34,826
or a winch, a wheel you crank
to wind or unwind a strap
168
00:11:34,828 --> 00:11:36,828
that hooks onto the boat.
169
00:11:36,830 --> 00:11:39,097
Boat trailers back up into water
170
00:11:39,099 --> 00:11:42,867
so using corrosion-resistant
materials is vital.
171
00:11:42,869 --> 00:11:44,536
This trailer is aluminum
172
00:11:44,538 --> 00:11:47,839
with torsion axles made
of galvanized steel.
173
00:11:47,841 --> 00:11:51,710
Torsion axles contain
shock-absorbing rubber cores.
174
00:11:51,712 --> 00:11:55,747
On each axle,
a machinist greases the spindle,
175
00:11:55,749 --> 00:11:59,250
and installs a mounting
bracket for the brake caliper.
176
00:11:59,252 --> 00:12:02,387
All the nuts and bolts holding
the trailer's parts together
177
00:12:02,389 --> 00:12:05,523
are stainless steel.
178
00:12:05,525 --> 00:12:08,393
The machinist mounts the wheel
hub on the spindle.
179
00:12:08,395 --> 00:12:12,497
The brake rotor is built
right into the hub.
180
00:12:12,499 --> 00:12:15,066
He secures the hub
with a castle nut
181
00:12:15,068 --> 00:12:19,537
and adjusts the tension.
182
00:12:19,539 --> 00:12:22,273
He inserts a cotter pin
to lock the castle nut,
183
00:12:22,275 --> 00:12:27,412
bending the pin with
a few taps of a hammer.
184
00:12:27,414 --> 00:12:30,682
He pumps grease into
the hub for lubrication
185
00:12:30,684 --> 00:12:35,386
then taps in a dust cap
to seal in the grease.
186
00:12:35,388 --> 00:12:38,823
He installs the brake caliper
on the mounting bracket.
187
00:12:38,825 --> 00:12:41,126
He hooks up the brake
line to the caliper
188
00:12:41,128 --> 00:12:42,827
and mounts the tire to the hub.
189
00:12:46,867 --> 00:12:48,366
on the back of the tire,
190
00:12:48,368 --> 00:12:53,738
there's a small brass elbow
for connecting the brake line.
191
00:12:53,740 --> 00:12:57,208
The frame that sits on
the axles is made of aluminum.
192
00:12:57,210 --> 00:13:00,145
Aluminum is strong
and corrosion-resistant
193
00:13:00,147 --> 00:13:03,348
but also lightweight.
194
00:13:03,350 --> 00:13:06,918
The frame has two main
front-to-back beams.
195
00:13:06,920 --> 00:13:09,554
Using a template
for accurate positioning,
196
00:13:09,556 --> 00:13:11,723
another machinist
punches boltholes
197
00:13:11,725 --> 00:13:14,726
into the beams
with a hydraulic tool.
198
00:13:14,728 --> 00:13:17,228
He uses a bending press
to curve the beams
199
00:13:17,230 --> 00:13:19,564
to the specified angle.
200
00:13:19,566 --> 00:13:21,466
This type of
aluminum can be bent
201
00:13:21,468 --> 00:13:24,669
without compromising
its strength.
202
00:13:24,671 --> 00:13:26,504
Next, an anti-corrosion coating
203
00:13:26,506 --> 00:13:29,874
is brushed onto the axle's
mounting plates.
204
00:13:29,876 --> 00:13:33,044
Technicians position the beams
on the axle plates,
205
00:13:33,046 --> 00:13:37,515
aligning the matching boltholes.
206
00:13:37,517 --> 00:13:40,084
They bolt the beams
to the plates,
207
00:13:40,086 --> 00:13:44,556
then bolt a rear crossmember
underneath the two main beams.
208
00:13:44,558 --> 00:13:47,091
This gives the frame
side-to-side strength
209
00:13:47,093 --> 00:13:49,594
and stability
in addition to helping
210
00:13:49,596 --> 00:13:52,330
support the load of the boat.
211
00:13:52,332 --> 00:13:55,700
A pair of mounts are bolted
onto the rear crossmember
212
00:13:55,702 --> 00:13:58,203
and on each of the two axles.
213
00:13:58,205 --> 00:14:00,839
The bunk, the part
that supports the boat,
214
00:14:00,841 --> 00:14:05,710
slots into the gap between
each pair of mounts.
215
00:14:05,712 --> 00:14:08,012
The bunk has a wood cap
that's carpeted
216
00:14:08,014 --> 00:14:11,516
to protect the boat's hull.
217
00:14:11,518 --> 00:14:12,884
To reinforce the bunk,
218
00:14:12,886 --> 00:14:15,553
punch holes are made
in aluminum plates
219
00:14:15,555 --> 00:14:19,924
and bent with a press.
220
00:14:19,926 --> 00:14:22,126
Sway braces are bolted
to the mounts
221
00:14:22,128 --> 00:14:23,428
for additional support.
222
00:14:27,834 --> 00:14:30,735
this company makes
a patented pivoting bunk
223
00:14:30,737 --> 00:14:34,038
that adjusts to boat hulls
of varying shapes.
224
00:14:35,575 --> 00:14:39,344
at the front of the frame,
machinists install the tongue.
225
00:14:39,346 --> 00:14:42,380
The tongue unites the two main
beams with the coupler
226
00:14:42,382 --> 00:14:45,283
that hooks up to the toe hitch
at the rear of the vehicle.
227
00:14:47,387 --> 00:14:49,053
for trailers with a winch,
228
00:14:49,055 --> 00:14:54,092
aluminum parts are cut
for the winch stand.
229
00:14:54,094 --> 00:14:57,428
A technician places the parts
in an assembly jig
230
00:14:57,430 --> 00:14:59,030
which aligns them correctly.
231
00:15:03,136 --> 00:15:05,470
then, the parts
are tack welded together.
232
00:15:10,543 --> 00:15:12,377
once welding is complete,
233
00:15:12,379 --> 00:15:15,313
the technician removes them
from the jig,
234
00:15:15,315 --> 00:15:17,882
tack welds one additional part,
235
00:15:17,884 --> 00:15:20,485
then welds
all the parts together.
236
00:15:24,291 --> 00:15:27,025
he removes any debris
from the welded seams
237
00:15:27,027 --> 00:15:28,393
with a cleaning solution.
238
00:15:32,065 --> 00:15:35,300
next, the winch stand
is bolted to the tongue
239
00:15:35,302 --> 00:15:37,302
and the winch is installed.
240
00:15:37,304 --> 00:15:40,071
Then, the brake line
and the electrical cable
241
00:15:40,073 --> 00:15:42,840
for the trailer's l.E.D. Lights
are connected.
242
00:15:42,842 --> 00:15:46,544
Guides are also installed, which
center the boat on the trailer.
243
00:15:48,682 --> 00:15:52,383
an aluminum fender is mounted
over each pair of tires
244
00:15:52,385 --> 00:15:54,919
and reinforce it with
a support bracket
245
00:15:54,921 --> 00:15:56,621
which they bolt to the frame.
246
00:15:59,659 --> 00:16:02,093
latch system trailers
have an aluminum bar
247
00:16:02,095 --> 00:16:03,828
which stops the bow,
248
00:16:03,830 --> 00:16:07,332
securing the boat at
just the right position.
249
00:16:07,334 --> 00:16:11,302
Finally, this tow trailer is
ready for smooth sailing.
250
00:16:25,118 --> 00:16:28,252
narrator: There's a lot more to
candles than lights the eye.
251
00:16:28,254 --> 00:16:31,122
Before they were invented,
people relied on candles
252
00:16:31,124 --> 00:16:34,926
made with wicks floating
in flammable, spillable oil.
253
00:16:34,928 --> 00:16:38,763
In the past, candles weren't
just used for illumination.
254
00:16:38,765 --> 00:16:41,132
Since they burn
at such a steady rate,
255
00:16:41,134 --> 00:16:44,369
people have even
used them as clocks.
256
00:16:46,539 --> 00:16:47,805
thanks to electricity,
257
00:16:47,807 --> 00:16:51,009
candles no longer have
to illuminate our homes.
258
00:16:51,011 --> 00:16:53,077
They can simply
brighten our evenings
259
00:16:53,079 --> 00:16:56,347
with atmospheric lighting.
260
00:16:56,349 --> 00:16:59,717
This wax has been made into
a powder with a rotating bar
261
00:16:59,719 --> 00:17:03,554
that sprays drops of
hot wax into the air.
262
00:17:03,556 --> 00:17:09,193
As the drops fall, they cool
and become solid wax particles.
263
00:17:09,195 --> 00:17:11,896
A specialized machine
called a core press
264
00:17:11,898 --> 00:17:16,034
vacuums the powder and begins a
multi-step process.
265
00:17:16,036 --> 00:17:20,271
A series of small
tube-shaped holes with powder
266
00:17:20,273 --> 00:17:23,107
then hydraulic pistons
compress the powder
267
00:17:23,109 --> 00:17:25,810
into short cylinders.
268
00:17:25,812 --> 00:17:31,082
Transport units move
them to the next station.
269
00:17:31,084 --> 00:17:34,919
The compressed wax cylinder
will form the core of the candle
270
00:17:34,921 --> 00:17:36,621
and prevent the burning wick
271
00:17:36,623 --> 00:17:39,490
from touching
the edges of the glass.
272
00:17:39,492 --> 00:17:42,593
First, it needs
a wick and a sustainer.
273
00:17:42,595 --> 00:17:45,930
The metal sustainer
is the wick's base.
274
00:17:45,932 --> 00:17:49,100
This machine shoots wicks
into the sustainers,
275
00:17:49,102 --> 00:17:51,235
crimps them,
and inserts the components
276
00:17:51,237 --> 00:17:53,004
into the candle core.
277
00:17:56,176 --> 00:17:59,010
a machine places drops of glue
278
00:17:59,012 --> 00:18:02,447
in the bottom of a series
of small glass containers
279
00:18:02,449 --> 00:18:05,817
before placing
the candle cores inside.
280
00:18:05,819 --> 00:18:08,319
The glue holds
the sustainers in place
281
00:18:08,321 --> 00:18:11,522
to prevent them from
sliding around when hot.
282
00:18:20,967 --> 00:18:23,401
onto the next phase
of production,
283
00:18:23,403 --> 00:18:27,138
liquefied wax is poured
into a mixing tank.
284
00:18:27,140 --> 00:18:30,141
A technician pours in
a series of additives.
285
00:18:30,143 --> 00:18:33,411
They include plasticizers
to help solidify the wax
286
00:18:33,413 --> 00:18:35,346
and prevent crystallization,
287
00:18:35,348 --> 00:18:37,281
as well as uv light inhibitors
288
00:18:37,283 --> 00:18:41,853
that can protect
the wax from color fading.
289
00:18:41,855 --> 00:18:45,857
He pours a premeasured quantity
of dye into the container.
290
00:18:45,859 --> 00:18:48,626
An agitator begins
the mixing process
291
00:18:48,628 --> 00:18:50,761
which takes 20 to 30 minutes
292
00:18:50,763 --> 00:18:55,266
to ensure that everything
is thoroughly combined.
293
00:18:55,268 --> 00:18:59,804
The wax is maintained
at 185 degrees fahrenheit
294
00:18:59,806 --> 00:19:05,076
so the liquid is kept in
its liquid state.
295
00:19:05,078 --> 00:19:07,879
Then, the liquid wax
travels through tubing
296
00:19:07,881 --> 00:19:10,648
to a computerized
filling station.
297
00:19:10,650 --> 00:19:12,950
A set of nozzles fill the jars,
298
00:19:12,952 --> 00:19:15,353
surrounding
and covering the cores.
299
00:19:15,355 --> 00:19:17,755
Once filled,
the jars move slowly
300
00:19:17,757 --> 00:19:21,826
through two separate
cooling chambers.
301
00:19:21,828 --> 00:19:25,296
The candles undergo extensive
quality control testing
302
00:19:25,298 --> 00:19:26,664
for flame height
303
00:19:26,666 --> 00:19:31,903
and the temperature on
the exterior of the container.
304
00:19:31,905 --> 00:19:35,907
This facility also
manufactures tea light candles.
305
00:19:35,909 --> 00:19:38,276
The containers are
made of aluminum alloy
306
00:19:38,278 --> 00:19:42,046
pressed into a cup shape with
small panels at the bottom
307
00:19:42,048 --> 00:19:46,117
designed to direct
melted wax to the center.
308
00:19:46,119 --> 00:19:49,487
Moved by air, the containers
fall into a sorter
309
00:19:49,489 --> 00:19:52,290
which spins them into
an upright position
310
00:19:52,292 --> 00:19:54,926
and onto a conveyor
that offloads them
311
00:19:54,928 --> 00:19:57,261
to the next stations.
312
00:19:57,263 --> 00:20:00,765
Like candles, tea lights require
sustainers and glue
313
00:20:00,767 --> 00:20:02,733
to hold the wick in place.
314
00:20:02,735 --> 00:20:07,305
The steel discs drop into
a vibrating sorting device.
315
00:20:07,307 --> 00:20:12,210
A giant spool of waxed thread
is fed into the wicking machine
316
00:20:12,212 --> 00:20:15,580
the machine cuts, and inserts it
into the sustainer clip,
317
00:20:15,582 --> 00:20:19,250
and glues the assembly
into a tea light container,
318
00:20:19,252 --> 00:20:22,253
the containers, with
sustainers and wicks in place,
319
00:20:22,255 --> 00:20:24,488
move to a circular
buffering table
320
00:20:24,490 --> 00:20:28,359
which disperses
into three channels.
321
00:20:28,361 --> 00:20:31,262
A multi-prong device
advances the containers
322
00:20:31,264 --> 00:20:36,200
onto the filling machine's
conveyor system.
323
00:20:36,202 --> 00:20:39,704
The machine fills the containers
in a two-step process,
324
00:20:39,706 --> 00:20:42,473
filling them halfway,
letting them cool,
325
00:20:42,475 --> 00:20:46,277
then topping them up and cooling
the completed product.
326
00:20:46,279 --> 00:20:49,847
The two-step filling process
ensures a consistent product
327
00:20:49,849 --> 00:20:53,217
at a faster manufacturing rate.
328
00:20:53,219 --> 00:20:56,187
The cooling chamber circulates
air through the space
329
00:20:56,189 --> 00:20:57,855
at a specific temperature
330
00:20:57,857 --> 00:20:59,991
to cool the candles
at a calibrated rate.
331
00:21:02,996 --> 00:21:04,395
from start to finish,
332
00:21:04,397 --> 00:21:08,466
it takes just 45 minutes to
produce and package a tea light.
333
00:21:10,737 --> 00:21:13,437
there's a lot more to
that cozy candle glow
334
00:21:13,439 --> 00:21:15,439
than just wax and wicks.
