How To Carve Wax For Casting
Creating faceted edges in wax.
How to carve wax for casting. Once I have it cast normally in silver that is mixed in a 97 alloy because it casts easy and is easy to engrave I will then re-sprue and vulcanize for mass production should that be the need. Now I sprue up the carved purple wax by joining the blue sprue wax with heat then into the investment powder and cast it using a centrifugal caster. Inspired by a Wax Modelling book Id received here I have a go at carving a high doom ring out of carving wax.
Now it needs to sit for about 10 - 15 undisturbed until it sets up then it needs to sit for about 15 - 2 hours before you can start the burnout process in the kiln. We switch to finer hand tools and carve much slower to refine the final shape. You can even rub your fingers across it fast creating friction and causing it to get soft.
The top of the ring is trimmed down into a rough hexagon shape. To do this the wax model is sprued to a wax tree put into a special container and then filled with investment plaster. With vacuum casting you need to leave at least 18 of an inch at the top to aid in the suction during the casting.
Carving out a designed shape in your wax. There are a few steps you can take to make sure there are no unwanted rough edges on your wax carving before going through the lost wax casting process. Once you have made the original wax piece you take itsend it to your local casters to be cast into the metal of your choice.
This board is dedicated to wax modeling and carving. Move the file on the wax in a direction so as to not cut grooves in the wax from the file. First enlarge one aspect then turn the sample or tube over to trim the opposite side.
Use 1000 grit wet sandpaper to smooth the wax. This gives the basic instruction about using tools discussed in the carving steps. Then outline the pattern on the ring with a scribe to provide a guidance on where the first cuts are going to be.
