Preheating / holding times

Starting temperature

850 °C / 1562 °F

(Switch on the preheating furnace in time)

100-g investment ring – min. 45 min

Holding time after reaching

200-g investment ring – min. 60 min

the final temperature of 850 °C / 1562 °F

300-g investment ring – min. 90 min

If more than 2 investment rings are preheated at the same time, the holding time at the final temperature

has to be prolonged by 15 minutes per additional investment ring.

Note

If several Speed investments are to be conducted, they should be invested consecutively and placed into the

preheating furnace at an interval of approx. 20 minutes.

When placing the investment rings in the preheating furnace, make sure that the furnace temperature does

not drop substantially. The stipulated holding time counts from the point when the preheating temperature

has been reached again.

Important information

– Do not use a debubblizer (tenside). Reactions with the investment material may occur.

– Consistent results can only be achieved under consistent conditions and if the Instructions for Use are

observed.

– Dilute the liquid exclusively with distilled or de-ionized water.

– Liquid concentration: The more distilled or de-ionized water is added to the mixing liquid, the lower the

setting expansion. Additionally, the strength of the investment material is reduced. Do not dilute the

liquid to below 40%.

– Use only dry, clean instruments to process the investment material. Do not use plaster mixing cups.

– Carefully cut open the powder bags and remove the entire contents of the bags.

– Do not invest under pressure, since this changes the product properties.

– The setting time must be closely observed, since it decisively influences the expansion.

To ensure thorough heating of the investment rings in the preheating furnace, the following points

have to be observed:

– Load the preheating furnace to maximally half of the available utility space.

– Always place the investment rings in the rear part of the preheating furnace.

– Place the investment rings as quickly as possible in the preheating furnace. Make sure that the furnace

temperature does not drop substantially.

– Always remove pressed investment rings from the press furnace immediately after the end of the program

and place them on a grid for cooling.

– Always place the investment rings in the preheating furnace with the opening facing down.

– If more than two 200-g investment rings have to be preheated in the preheating furnace, we recommend

investing them consecutively and placing them in the preheating furnace at an interval of approximately

20 minutes.

– Do not place the investment rings in direct contact with each other. Allow air circulation.

Safety notes

– Do not open the furnace during the first 20 minutes of preheating: Burn hazard caused by wax fumes that

might ignite in the air!

– This material contains quartz, which may cause lung diseases (silicosis or cancer) when inhaled. Prevent

the inhalation of dust and wear a suitable dust mask.
