230 Casting System Crowns and bridges Stand 1.9. 03 A 4

Preheating Crowns/Bridges

To achieve optimum expansion values and stable muffles,

we recommend 3–4 side-heated circulating air ovens with

program control (4 soaking stages) and temperature control

(5°C/41°F per min), e.g. Protherm circulating air preheating

oven (Ord.-No. 096-180-00).

There is a risk of cracking of the muffle if the oven does not

have sufficient insulation and the heating/cooling time is too

short. Do not fill the muffle space to capacity.

Overnight operation is recommended.

Holding times: 150°C / 302°F 90 minutes

250°C / 482°F 90 minutes

1000°C / 1832°F 60 minutes

Slow reduction of temperature to 430°C / 806°F = casting

temperature. Avoid temperature shock. Do not hold at final

temperature of 430°C / 806°F longer than 120 minutes.

Expansion control for Crowns/Bridges

The adjustment of the expansion for the rematitan

plus

investment is exclusively done by dilution of the mixing

liquid. (see chart below).

Attention!

The mixing liquid is a concentrate which normally must be

diluted:

Recommendation for dilution:

Crowns and bridges:

60% = 6 parts of liquid + 4 parts of distilled water.

Conical and telescopic crowns:

70–100% = dilution related to the desired friction and ways

of processing.
