4. Technical description
4.1 Function
The FINOSINT KOMPAKT High-Temperature Sinter Furnace is used to fire sinterable ceramics.
The product to be sintered is placed in the sintering dish and set on the support pins in the combustion
chamber.The heat-up process starts after entering the heating parameters and pressing the Start button.
Once the heating program has ended and the sintering oven has cooled down, the finished product can be
removed from the oven.
Heating chamber
The product is sintered in the heating chamber. This consists of two different ceramic insulation layers and is
operated using four heating elements connected in series. The outer insulating layer is designed for temperatures up to 1200 °C; the inner layer for temperatures up to 1650 °C.
Oven door
The oven door consists of a two-part ceramic door panel. A safety switch disconnects the heating current as
soon as the oven door is opened.
The oven door has an electronic lock and can be opened only if the temperature is below 300 °C.
Oven housing
The oven housing consists of steel plate coated with plastic on both the inside and the outside and is cooled
by a permanent ventilation system.

NOTICE
The protection of persons can no longer be ensured and no liability can be assu-
Program controller
The program controller has a finishing-time setting that can be used to specify a day and time for the program
to finish. The switch-on time is calculated automatically so that the heating process is stopped at the required
time and the sintered item can be removed.
Operating parameters and heating programs are stored in a non-volatile memory and are retained even if the
power supply fails.
The set target temperature is maintained within an accuracy of ± 1 °C. A temperature sensor integrated into
the heating chamber measures the temperature of the chamber close to the product.
A thermocouple fail-safe prevents the sintering oven from overheating if the temperature sensor becomes
defective.
4.2 Intended use
The FINOSINT KOMPAKT High-Temperature Sinter Furnace is a high-temperature oven for commercial
application in dental laboratories and may be used only for sintering sinterable ceramics using original spare
parts.
At a total output >1kW, no limit values for the harmonics apply.
med for damage that is caused by misuse, incorrect operation, incorrect connections or improper maintenance/repair work carried out by untrained personnel. All
warranty services are also excluded in such cases.
The use of spare and wearing parts that have not been procured from the manufacturer will render the approval and guarantee of the sintering oven null and
void.
4.3 Potential misuse
• Operation by untrained and insufficiently qualified personnel.
• Use of products that have not been approved by the manufacturer.
• Use of replacement parts that have not been approved by the manufacturer.
