Meeting today's higher standards of Platinum Jewelry Designers and delivering "consistent" results every time.


01
Weigh Investment.
34ml water to 100g powder.
 02
Measure Water
Water Temperature:
70°F/21°C to
80°F/27°C
 03
Always add investment to water.
 04
Begin mixing by hand to avoid excessive
dusting.
0506
Mix approximately 12 minutes
  1. 1. Start at a slow speed (#1 on a Hobart™ Mixer, 2-1/2 hp motor recommended). The slurry will take on a granular appearance at about 2-1/2 minutes.
  2. At 5 minutes stop the mixer and remove residual powder from mixing blade and walls of bowl.
  3. Continue mixing for 7 minutes.
  4. At completion of mixing, the slurry should be very fluid and easy to pour.
07
Common Sprue Arrangement
  1. Pin Cusion
  2. Standard Sprue Tree
 08
Attach sprue tree directly to two sheets of heavy duty absorbent disposable paper towels
 09
Place flask over sprue tree. Ensure that there is at least 1 to 1/2" of investment above the top of the sprue tree (highest wax model)
 10
Wrap both paper towels around flask and secure with a rubber band or wax.
11
 Place a small piece of cardboard underneath flask to provide additional strength during investment pouring and vacuuming. Cardboard should be at least 1/8" wider than circumference of flask. 12
Place a collar extending 2-3" above the top of flask, using either tape or rubber sleeve.		 13
Pour the slurry down the side of the flask. Avoid pouring directly onto the sprue tree. Fill 1" (25mm) avove the sprue tree.
14
 Vacuum up to 90 seconds. Vibrate vigorously during vacuum procedure. Release the vacuum and add sufficient slurry to fill the collar to a height of 1 1/2" above the top of the flask (depending on the flask height) 15
Carefully slide invested flask off of cardboard base.		 16
Place on to 1" (25mm) stack of highly absorbent paper towels.
17
Let sit undisturbed for 16 hours. A small desk fan and bench lamp can be used to accelerate the evaporation process.
18
Decant any water from the top surface of the investment. Remove collar and paper towel wrapping.
 19
Carefully scrape excess investment fromtop and bottom of flask.
 20
Burnout Process
Hold 2 hours at 200°F / 93°C. Ramp to 1600°F / 871°C for 5 hours at 3°F / -16°C per minute. Hold 2 hours at 1600°F / 871°C. Bring to casting temperature and hold for a minimum of one hour. Cast as quickly as possible after removal fromthe burnout oven.
 21
Deflasking
The flask should be cooled at room temperature. This may be accomplished by water quenching once the metal has cooled below red hot, provided that the metal can tolerate quenching. The casting can then be pushed out by hand.
