It was a great contrast to visit a traditional 22-karat gold
jewelry manufacturer and then to visit a modern jewelry
manufacturing company that incorporated more
mass production techniques such as wax carving, mold
making, and casting, along with traditional hand-fabrication
techniques, but using more modern tools
and modern benches, as well as incorporating much more stone
setting with a variety of gem materials.
This is the design.
She already supplied this design that according to this design,
he'll make the master piece.
He has done this design.
He is doing filing.
Now he's soldering that.
Then they may make a sprue of this soldering.
After that, it is ready for mold cutting.
It's the master piece.
This is the first process.
This is the silver.
And this is the copper because the cost
is a little lower with silver.
Compared to gold, the silver is slightly lower.
And here is pack one rubber.
This is the rubber they are using-- imported castable
rubber.
Four layers.
How long does it take?
35 minutes for 77 Celsius-- 158-- 158 Celsius-- 35 minutes
to burn-- baking this rubber.
After cutting, we get waxes from here.
Every day she takes 600 pieces.
That's 600 pieces.
She gets the wax every day.
We have to adjust this pressure in the vacuum-- the auto-clamp.
So depending on the mold-- when the mold is-- the rubber
product is very thick, we have both
increase the pressure in the vacuum.
The small particles reduce the pressure in the vacuum.
She's doing repairs.
We have some repairs on wax pieces.
So that's what we're doing.
And after treeing, she's doing on that job.
It's like a quality check.
Then she's doing a third tree.
Prepare the investment.
Now it's ready to investment mixing.
So first we put water then the powder.
Investment mix powder.
It's ready to mix in.
Now, it's the machine on.
He's closing the chamber so that it creates vacuum.
Then the motor is working.
Now it's mixing the investment.
So get four minutes to mix it and pouring.
Then three minutes for vacuuming.
Seven minutes cycling.
Actually, the top chamber-- four minutes
and the down chamber-- three minutes vacuuming.
This is the process of vacuuming and mixing.
After four minutes, they pour to the flask.
And after the flask, three minutes of vacuuming.
After one hour, we remove the tape and cover.
Keeping that hour.
Full program controller for this one.
It was cycling-- we've done this-- for this one flask.
After this burnout cycling is finished, then
casting of this machine-- casting.
This is the flask size-- one kilo
flask-- the melting flask possible.
This is for one kilo capacity.
This is the vacuum casting machine.
We're pouring.
Now it's metal pouring in the flask.
They have finished the casting.
Now it's to water.
[VIBRATING SOUND]
Now he's cutting the sprues.
[SAWING SOUND]
After sprue cutting-- filing.
[FILING SOUND]
Making a loop hook.
We have two soldering processes.
One is manual and the other one is laser.
This is where we use the laser.
The surface finish in some solution.
That's a polishing solution that they
import from India-- this vibrating machine.
This is also working with steel shot.
[VIBRATING SOUND]
Colored stones and gems-- natural stones--
synthetic stones.
They have a lot of selection.
Take amethyst color.
To set stone, this is called shellac
that we're using for setting like a glue compound.
It's setting the stones.
Make the prongs neat.
Clean with-- this is called the ultrasonic cleaner.
Wash with water.
Then now we're going to polish it.
Now, it's polishing with the bristle drill
with rouge-- white rouge.
That's for cutting the surface to high polish.
The ultrasonic cleaner.
Wash with water.
Steam with a steam cleaner.
Gold plating.
It's doing plating for 22-karat.
With the steam cleaner there is now going to quality check.
She is now checking the setting and the plating
using the OptiVisor.
She's checking.
She's checking quality.
The quality-checking is finished.
Now, we make a weight and all the things.
For this order we have to send to the showroom.
So it's past the entry to the showroom.
It's internal entries.
So past the entry to showroom.
And finish there.
Make a printout and send to our retail showroom.
