10/2018 Version 4.0en Operating Manual Tabeo Sintering Oven Metal Page 11
Technical description
Function
The Tabeo sintering oven is used to re 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 nished product can be removed from the oven.
Heating chamber
The product is sintered in the heating chamber. This consists of two di󰀨er-
ent 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 tem-
perature 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.
Program controller
The program controller has a nishing-time setting that can be used to spec-
ify a day and time for the program to nish. 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.

Sintering with argon
The sintering of NEM is possible only in an oxygen-reduced atmosphere.
This is attained by using argon. Argon is an inert gas in a compressed gas
bottle. Always use argon bottles with a pressure gauge as well as a pressure
reducer. The purity of the argon must be at least 4.6= 99.996 % vol. During
the sintering process the argon ow is 1 l/min.

The lling level of the compressed gas can be determined at the pressure
gauge. A new argon compressed gas bottle is lled with 200 bar.

A 50 litre compressed gas bottle of argon with a lling pressure of 200 bar
contains approx. 10,000 litres of argon.
At a ow of 1 l/min, the consumption per sintering process is approx. 270
litres.
With a 50 litre compressed gas bottle, approx. 35 NEM sintering processes
are possible.

Connecting the argon supply
$Danger
Danger due to escaping gas!
Potential risk of explosion or re as well as su󰀨ocation.
hDuring all work on the Tabeo-2/M/Metal-120, the argon and voltage
supply must be shut o󰀨 (pull out mains plug) and the gas bottle must
be closed.
hWhen working with argon, observe the national safety regulations
TRGS526 (Chapter 5.2.11 “Compressed gas bottles and ttings”).
1. Close the connecting hose (included in the delivery) at the sintering
oven (A) and the argon supply (gas bottle).
Abb. 2: Argon connection Tabeo Metal (illustrative example)
2. Set the outlet pressure of the gas bottle to 6-7 bar (optimal pressure!).
Maximum pressure: 10 bar!
Notice
If the outlet pressure of the gas bottle is higher or lower than 6-7 bar, too
much/too little argon will enter the sintering dish and the sintering process
will fail!
3. Check the gas lines and connected couplings for leaks and a secure
t.
ÂIn the event of a malfunction the volume of an argon bottle is su󰀩-
cient to ood the entire room.
A ventilation in the oor area is recommended (argon is heavier than
air and settles on the oor).
4. Protect the ducts and shafts against penetration by gas.
