How To

How to Calculate NeuSprue Button Size To Reduce Metal Loss

When you cast with NeuSprue, knowing how to calculate the precise amount of metal you will need for your sprue button helps to minimize metal loss and use your precious metals more effectively.

1 The button portion of the NeuSprue™ has been economically designed to conserve metal usage while still supplying a needed reservoir of metal for the solidification process.

2 Because the NeuSprue wax button is hollow, the cast button will only be 1/3 full of metal.

3 To control the size of the button after casting, take the overall weight of your NeuSprue wax tree and subtract 4.7 grams (this will cast the tree without a button).

4 Then, simply add back the wax gram weight, up to 7.6 grams, that you want your final button to be. The full 7.6 grams will result in a full button after casting.

How to Choose An Appropriate Gate Size for Your Ring Patterns

Know how to design effective feed gates for your master ring pattern. A well-designed gate helps streamline the flow of metal into the pattern and helps reduce defects caused when metal can't effectively reach all parts of your pattern.

1 The main feed sprue diameter should equal
the sum of the two connecting gates for
optimal flow of metal into the pattern.

2 Balance the thickness with a single sprue of equal thickness, and there should be equal thickness everywhere.
Please Note: Round gates are best, and
3mm round is the best for most patterns.

How To Determine Metal Weight for Wax Trees

Knowing how to determine the correct metal weight for each wax tree before you cast ensures that you melt the right amount of metal for your cast, making your casting process more cost-effective and more reliable.

SPECIFIC GRAVITIES:
24KY = 19.32
18KY = 15.58
14KY = 13.07
10KY = 11.57
Fine silver = 10.49
Sterling = 10.36
Platinum = 21.54
Caster's brass chunks = 8.4
Caster's white bronze chunks = 8.1
Ancient bronze = 8.8
Yellow bronze = 8.4
Manganese bronze = 8.3
Nickel silver = 8.8
Alpaca = 8.6

Step 1
First, weigh your wax models along with main and gate sprues. Then add an additional 10% to account for your button.

Step 2
Multiply that total by the specific gravity of the metal you're casting (see table above for a general guideline).

Step 3
Example: For a 5-gram wax model, add 0.5 (10% of 5g) to get a total wax weight of 5.5g. For a 14KY gold casting, multiply 5.5g x 13.07 s.g. The amount of 14KY gold needed for this tree is 71.89 grams.

How To Evaluate the Effectiveness of Shrink Bands

Here is a concise comparison to illustrate how to evaluate the effectiveness of covering perforated flasks with Shrink Bands vs. other methods (masking tape and rubber sleeves).

SHRINK BANDS:
• Easy and fast to apply
• Complete, waterproof, effective seal
• See-through
• Easy to remove

MASKING TAPE:
• Easy to apply

RUBBER SLEEVES:
• Difficult to apply smoothly to flask
• Effective seal once properly applied (must be completely wrinkle- and fold-free)
• Becomes progressively less effective over time as elasticity deteriorates
• Difficult to remove
• Must be cleaned prior to re-use
