http://www.ComposiMold.com Master how to Mould and Forged Rubber Ducks into a Plastic Duck applying ComposiMold and Urethane Resin
This is a simple just one part mildew of a rubber duck. To cease the rubber duck from floating when the ComposiMold is poured around it, clay and sand was set inside of the rubber duck. It also could have been glued down with very hot glue to the bottom of the container.
The part was then coated with Bubble Buster to lessen bubbles from adhering to the part. We dip it into the Bubble Buster, but we could also have sprayed it on. Be positive to get it into any crevices.
The duck is placed inside of a mildew box. We utilised a PVC pipe, but any container that can handle a very little heat will do. You can also use legos to create a box or aluminum foil that has been sprayed with a mildew launch also functions well.
Soften the ComposiMold and pour around your part. To soften the ComposiMold, adhere to the path on the label. Soften in brief intervals until eventually you are at ease with how it melts in your microwave. You can also use a double boiler or a chocolate melter.

We don’t display it in this movie, but the ComposiMold is cooled promptly by inserting it in the freezer. It took around 30 minutes to amazing, but to guarantee it was really cold right before pouring in the urethane resin, we remaining the mildew in the freezer for 2 hours.
You then get rid of the duck from the mildew and spray the inside of of the mildew with a mildew launch that is intended for urethane resin.
The ProtoCast urethane resin is a vibrant white plastic with a demold time of 15 to 20 minutes.
Even though the mildew is nonetheless cold, pour in a PrototCast Urethane resin. The urethane is mixed 1:1 by quantity.
If necessary, location ComposiMold back into the freezer to preserve the mildew cold though the urethane is curing. This assists lessen any melting of the ComposiMold from the exothermic response from the Urethane. Lengthier get rid of time resins have a lot less of this heat.
At this time, the plastic duck is made. You can remelt the mildew to make a new mildew, or you can make yet another casting with the ComposiMold mildew.
Below we also display the plastic duck made with ComposiCast urethane resin. It functions the exact same way. Be positive to preserve the mildew amazing if necessary throughout the approach.
The keys to results for a urethane casting is to use Bubble Buster when creating your mildew
-Maintain the ComposiMold cold throughout the approach
-Use a mildew launch intended for urethane resin and make positive it is completely dry.
-And if achievable, use lengthier get rid of time resin units.
