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 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.
IMPORTANT! 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.
