In this week, we learn about molding and casting. We test different materials and evaluate them while following proper safety measures.

Objective of group assigenment

• review the safety data sheets for each of your molding and casting materials, then make and compare test casts with each of them
• compare mold making processes
We are used diffrent materials for molding and casting and we are comaping the properties of the diffrent materials and we are also campare the molding process for the diffrent materials.
Wax

Clear resin

Instamold

Hydrostone superx gypsum cement

Materials available in the lab for testing.

1) Crafty Nibbles
2) Instamold
3) Ecoflex
4) Epoxy resin
5) Easy mould Silicone Rubber
6) Machinable wax
All the materials are available in the lab and we can test them for molding and casting. some of the materials are use for molding and some of use for the casting. we can use the molding material to make the mold and then we can use the casting material to make the cast. we can also use the some material for both molding and casting. we can use the same maerial for both modling and casting.
