Muffle System

To avoid gas entrapment during casting, the sprue cone

must be of a certain shape. Use only the muffle bases

belonging to the system with sprue formers.

Muffle base with sprue former:

Size 3 1 piece Ord.-No. 106-850-01

Size 6 1 piece Ord.-No. 106-851-01

Size 9 1 piece Ord.-No. 106-852-01

The base plate must be completely clean.

Distance between wax frame and investment surface:

max. 6 mm.

Wax-Up

To achieve a clean and rapid melt flow, joints of the sprue

cone and onto the pattern should be smooth and round.

Align the pattern horizontally.

Keep the distance from the edge of the muffle approx. 6 mm.

The pattern should lie with its upper edge 6 mm below the

edge of the muffle rings. Consequently the length of the

main supply sprue will be 15–20 mm.

Wax: Reducing Tension

Before pressing the silicone rings over the base plate spray

the wax patterns with Lubrofilm

(Ord.-No.112-050-00) and

blow dry.

Muffle rings, flexible

Size 3 1 piece Ord.-No. 106-840-00

Size 6 1 piece Ord.-No. 106-841-00

Size 9 1 piece Ord.-No. 106-842-00

Use the muffle rings corresponding to the size of the muffle

base.

instructions for rematitan

followed.

Plus investment:

For muffle size 3 1 x 250 g

For muffle size 6 2 x 250 g

For muffle size 9 3 x 250 g

rematitan

Plus investment should only be mixed with the

special mixing liquid Ord.-no. 107-602-00.

Store the mixing liquid in the refrigerator at about 8–10°C/

46–50°F (not in the freezer compartment).
