Hey,I would appricate if someone could tell me, How Rubber Duckies are made!thanks?
I need to know the process.
Answers:
The basic process is called molding.
This process starts with a mold, which is two pieces of steel which have been carved out such that what will be the OUTSIDE of the duckie is the INSIDE of the pieces of steel -- one piece of steel contains the image of the left half of the duckie and the other piece of steel contains the image of the right half, so that when the two pieces of steel are pressed together there is a hole in the middle shaped like the outer surface of the duckie.
Now, if you filled that ENTIRE hole up with "rubber" (actually a soft version of PVC plastic is used these days) and let it cool then pulled the two steel pieces apart, out would pop a SOLID rubber duckie. That would (A) not float, and (B) waste a lot of expensive rubber.
To get a HOLLOW rubber duckie, you modify the process a bit and use either "roto-molding" or "blow-molding" (depending on the manufacturer).
In Roto-molding (rotational molding), you pour the hot rubber into the mold and then rotate the mold, so that the rubber sticks to the insides of the mold as it cools -- soon you have a thin (if somewhat uneven) layer of rubber coating the inside of the mold, so when you pull the mold halves apart out pops a hollow duckie.
In blow-molding (usually used for hard-plastic duckies rather than soft rubber ones), there is an opening where a little "baloon" of warm plastic is inserted on the end of a tube, and that balloon is then inflated with air through the tube -- it expands until it hits the walls of the mold, where it conforms to the mold and cools in that shape. Then again you pull the two mold halves apart and out pops a hollow duckie.
Finally the outside of the duckie is painted, and when the pain is dry the whole thing is boxed up and sent to a warehouse where it eventually is shipped to a store, put on the shelves, and sold to take home to your bathtub!

Rubber ducks aren't actually made of rubber anymore - there's your first point. And a mould will be used at some point. And some ducks are made from two halves, so mass produce the two halves and stick them together.
Of course, you could always go and research it yourself.
First you get a crate of live ducks and a big vat of hot gooey rubber. Dip the ducks in the hot gooey rubber. Allow to cool. Poke a small hole in the bottom of the left foot of each rubberized duck and suck out the duck. Tadaaaaaaa: You now have a rubber duck. Paint to suit you taste and you have a lifelong bathing buddy.
Rubber duck is a bit of a misnomer.
Molten plastic is poured over a small live duckling to attain the perfect shape then it is hung up to set hard. A hole is then made in the bottom through which the duckling is siphoned through at high pressure. The ducks are then tested on a small pond and the ones which fail to float properly are then turned into British Cabinet ministers.
Injection Moulding. Ie a metal shape of a duck and then under high presure, plastic is poured into a mould, cooled and then you have a rubber or should I say, plastic duckie.

Make your own Rubber Duckies (not the bath kind)
http://www.arrl.org/tis/info/pdf/9803037.
In as early as 200 BC, toy bath ducks were made in China and were highly thought of. The traditional Chinese ducks were bottom-heavy, resulting in a very bouyant upright duck which increased in popularity rapidly. However, they were not made of rubber until the introduction of rubber in the industrial world (1839). Now, they are almost always made out of vinyl plastic.
The introduction of the rubber duck to North America has had a serious effect on their bouyancy and performance. This is because the heads were made bigger (because of an emphasis on using brains) and so they capsized more easily. Another western addition was to change the colours of the duck, sometimes looking like celebrities, others red or blue, you can even get glow in the dark, colour changing or vibrating ones - but the yellow ducks are losing out.
