2 General Notes

2.1 General Safety Instructions

•Operating instructions must be read and followed by all personnel who use this device

•Furthermore, personnel should follow all local safety rules.

•To avoid injury, appropriate protective clothing, noise absorption, protective eyewear and

other tools have to be used.

•If the machine is defective or working improperly it must be taken out of service. Call your

dealer immediately then.

•This device has been designated to be used only for its intended purpose. All other

applications must be prohibited for safety reasons.

•In case of danger turn off the machine and call your dealer or manufacturer for help.

•This device should not be left running while unattended.

•Turn all power sources off after having finished work.

•Repairs may be carried out only by experts. Persons doing repairs take over responsibility

for proper work and adherence to accident-prevention regulations (UVV).

•Use original spare parts only.

•Modifications may only be made after consultation with, and by permission of the

manufacturer. In case of modifications without permission all warranty and liability claims

will expire.

•The machine should be operated in a clean, air-conditioned room with a temperature of 18

to 35° C.

•Danger of fire: Respect the fire regulations. Leave enough space around.

•Don’t use mobiles near the machine since they may lead to disturbances.

•Don’t place anything on top of the machine.

•REITEL GmbH assumes no liability for damages to surfaces caused by equipment

supports/feet.

2.2 Special Instructions for this device

•Never store explosive, highly inflammable or burnable material in the working area.

•The hot crucibles, pestles and muffles may only be deposited on a heat-resistant and fire-

proof base, like crucible support.

•Make sure to use the device only for melting metals and alloys in the crucibles meant for

this purpose.

•Don’t melt any material, generating toxic gas.

•The generator (function „melting material“) may only be switched on if the melting material

is already in the device.

•When the heating is on, don’t touch the inductor chamber with your hands or other things.

•Use pliers when inserting or taking out the muffle, mould or handling the thermoelement

because of danger of being burnt.

•Only open the casting chambers when there’s no excess pressure or under pressure.

•Be careful regarding handling gas bottles. Secure against falling down, don’t heat, handle

with care.

•The heating process incl. casting process may only last max. 3 minutes.

Alloys with a longer melting time are inadmissible.

•The rest time between a casting and starting a new heating process has to be at least 6

minutes. There may be no hot crucible in the device during this time. The muffle chamber

as well as inductor chamber have to be open for cooling reasons during this time.

•Entering the casting temperature for non-precious metals generally corresponds to

recommendation of the metal-suppliers. These recommendations are without engagement.

•Tip: several (approx. 5 castings) should be performed visually, possibly with different

temperatures, and in case of a good casting result the casting temperature should be

adopted results-oriented as a set value for a casting program.

•Regarding temperature measurement small metal quantities below 15 g are not

precise due to a lack of quantity and are difficult to cast. If false castings are

produced, often default imbedding or a wrong temperature assessment of the

metal melting is the reason.

•When processing non-precious metals and palladium-containing alloy in the

ceramics crucible, temperature measurement is only possible with the „Longlife -

pestle“.

Generally noble metal (NM) is molten in the graphite crucible, if applicable in the ceramics

crucible with the graphite seal pestle.

•When melting thin and few split noble metal pls. pay attention that they don’t

position vertically as there’s no coupling possible and the metal consequently

won’t melt. Therefore push together split metal, put old sprue onto the new

material or weld split metal together or spot-weld.

•Pls. pay attention to the maximum percentage part of old material and crush

sufficiently! The parts have to be positioned on the crucible’s base, otherwise

there will be no or only partly metal melting.

3 Installation

•In order to minimize casting time, the INDURET-COMPACT should be installed very near to

the preheating furnace.

•Don’t install the device in a dusty room, e.g. near a sandblaster.

•The INDURET-COMPACT is a benchtop unit. Ensure a stable placement on the benchtop

and leave enough space around the machine.

•Pls. check connectivity with type plate indications.

•In case of differences of power requirements in your location, we recommend the usage of

the following devices:

The gas cylinder is connected via a pressure minimizer.

Warning: This machine must not be operated by persons who wear a pacemaker.

Caution: handling gas bottles. Secure against tilting, don’t throw, don’t heat and pls.

control metal press pressure at the device’s gauge (3 bar at delivery).

Alternatively air can be used instead of argon. Pls. follow the manufacturer’s instructions

regarding connection of the pressure unit to the bottle.

The casting result is mainly effected by speed of building up air pressure.

Reference speed range fom –0,8 bar to 3.0 bar in 1-2 sec.

Therefore:

a) Ensure a short distance to the compressor

b) Flow opening of all connections and hoses: minimum 8 mm

c) Minimum air pressure: 6 bar (admissible pressure drop of the device: max. 0,5 bar)

d) Minimum tank volume 80 l or free compressor performance / permanent

compressed air supply 50 l/min.

e) Don’t bend the supply hoses

f) Keep compressed air supply free from water, dust and oil (normally a water

separator is installed, that has to be looked after regularly (see chapter “Maintenance”)
