Molding & Casting
Molding
Luciano explained the good practices to be followed while molding and casting. He introduced us to different kind of materials used for making molds. Taught us the difference between a positive and a negative mold, what is a counter mold etc.
The design should give 5mm clearance in all directions for forming a sturdy mold also the walls of the should have 5-10 degree slope.
After discussing all these we started the actual mold making process. We took the chemical for mixing, weighed them and mixed them properly. But as the humidity is very high their were chances of having the chemicals turn unusable.
We also used a color die for learning the process. Then we poured it into the milled wax and left it for setting.
all set for moulding
mixing the chemicals
Note: Even after 3 days it didn't set properly !! So the chemicals have gone bad for sure. And we did the moulding again the very next day with a model and mold designed by Luciano.
