Direct Sprue Wax for the Magicast ring system is a specialized wax component used in the lost-wax casting process — particularly in dental and jewelry casting — to create a direct channel (sprue) between the wax pattern and the casting reservoir.

Here’s how to use it and where in the process it fits:

Where to Use (Purpose):

The Direct Sprue Wax acts as a pathway for molten metal to flow into the mold cavity created by your wax pattern after burnout. In the Magicast ring system, it is designed to fit precisely into the system’s layout and provide consistent, bubble-free flow during casting.

How to Use:

1. Attach the Wax Pattern:

Carve or use a pre-made wax pattern (e.g., ring, crown).

Use a heated instrument to join the Direct Sprue Wax to your pattern — ensuring smooth joints to prevent turbulence during casting.



2. Position into the Magicast Ring Base:

The other end of the Direct Sprue Wax should be fitted directly into the Magicast base or crucible former. This ensures alignment with the ring system and keeps the wax securely in place.



3. Inspect for Clean Connections:

Ensure the sprue is attached at a 45-degree angle or as recommended, to allow optimal flow and reduce turbulence or air bubbles.



4. Invest the Assembly:

Place the assembled unit (pattern + sprue) into the casting ring.

Pour investment material to cover the pattern and sprue — this forms your mold after burnout.



5. Burnout:

The wax melts out during the burnout process, leaving a channel (sprue hole) in the mold.



6. Casting:

Pour or centrifuge molten metal into the mold — it flows through the former sprue channel into the cavity.

Tips:

Ensure the sprue is not too long or too thin, as that can cause incomplete fills or shrinkage.

Avoid sharp corners in wax connections — they can cause turbulence and trap gas.

The Direct Sprue Wax should match the Magicast system’s dimensions for a secure fit.
