FP1: Lost Wax & Margination
After applying ___________ to grasp die in skinny layers, observe die spacer within ____mm of
marked margin on master dies
die hardner/sealer
1mm
wax sample fabrication: steps after shifting wax coping to working solid
1. Add wax cones for fxl cusps
2. Upload marginal ridge define
three. Wax up F and L contours into occlusion
4. Wax up triangular ridges
surrounding the wax pattern with a cloth that could appropriately reproduction its form and
anatomic capabilities
making an investment
elimination of the wax pattern in order that a mould is created into which the molten alloy may
be located
burn out
introducing the molten alloy into the previously prepared mold
casting
what must you attach the sprue former to?
Thick non-practical cusp (ML of #30)
what reasons fins on casting?
-pattern too near quit of ring
-dropped ring
-heating too rapidly
-liner flush with stop of ring
-excessive casting pressure
