After cutting the specimen, the next step is mounting. The aim of mounting is to handle small or odd shaped specimens and to protect fragile materials, thin layers or coating during preparation as well as to provide good edge retention. Mounting produces specimens with uniform size so that it is easier to handle in automatic holders for further preparation steps.
Basically, two methods are available: Hot Mounting, Cold
Mounting
In hot mounting, the specimen is mounted under heat and pressure
with a hot mounting press.
Cold mounting is preferred for samples which are sensitive to
damage from heat and pressure (like coatings, PCB, etc.) Cold
mounting resins are easy to use and require mixing which is then
poured into a mould and allowed to set.
Automatic Hot Mounting Press, fully automatic
microprocessor controlled operation, touch pad front panel controls and
digital display of heating time, molding temperature, cooling temperature,
ram up/down, auto/manual cooling, cycle start/stop and a direct reading
pressure gauge. Molding pressure up to 310 Bar, molding temperature up to
240°C, thermostatically controlled heating power of 850 W, automatic
cooling cycle and an audible signal for end of cycle. Last molding
parameter settings retained in memory. Supplied with all necessary hoses,
fittings, power cord and instruction manual, selectable mould sizes from
25 to 50mm.
Semi-automatic Hot Mounting Press, 5 ton capacity.
Touch pad front panel controls and digital display of heating time,
molding temperature, cooling temperature, ram up/down, auto/manual
cooling, cycle start/stop and a direct reading pressure gauge. Self
contained bench design, integral heating and cooling unit,
thermostatically controlled heating power of 850 W, automatic cooling
cycle, with audible warning signal and ready for operation , selectable
mould sizes from 25 to 50mm.
Programmable Hot Automatic Mounting Press, microprocessor controlled,
program based mounting sequences, electro hydraulic pressure and drive
system(requires no air), programmable pressure up to 310 bar, programmable
temperature up to 240°C and programmable operation time up to 59:99
minutes, thermostatically controlled heating power of 850 W, automatic
cooling cycle with two modes of cooling rates(fast cooling and slow
cooling), programmable preheating and preloading, selectable mould sizes
from 25 mm to 50 mm, audible warning signal, large LCD screen and
touch-pad front panel.
Vacuum Impregnation Unit for cold mounting. Especially designed for
embedding and impregnation of porous materials under vacuum. In addition,
gluing of specimens to glass slides for thin section analysis is possible.
Vacumet is very simple to operate and ensures efficient impregnation.
