Labpress 40 Automatic Mounting Press
Embedding materials in a range of thermosetting
resins.

Features

Cut materials and irregular samples need to be
mounted in a plastic material so that surface can be ground and polished
to reveal surface structure or to produce a flat parallel surface for
hardness measurement. The two usual methods of mounting samples are to
use cold mounting resins or to use resins which can be moulded at
elevated temperature and pressure. The hot compression mounting process
can be carried out with the Labpress 40. It is preferred to cold
mounting for the following reasons :
(i) The method produces parallel sided block which is necessary for hardness measurement
(ii) A moulded block is produced in a rapid time of say 10-15 minutes
as compared to cold mounting
(iii) Hot compression mounting does not need to be done in a
fume cupboard.
(iv) The generally used phenolic mounting resins are very economically priced as compared to many cold curing resins
The Labpress 40 is an advanced Mounting Press with automatic pressure
and temperature cycle for compression mounting of samples in a range of
thermosetting plastics. It is a compact bench top unit with integral
hydraulic pump. It is only necessary to set the temperature & time
(pressure is factory set ) and then START CYCLE to produce an embedded
sample.
Construction
The hydraulic system comprises a compact integral pump acting on a 50mm
cylinder which is used to amplify the pressure being applied to the
lower piston in the mould. A pressure adjuster is located inside the
cabinet. It is factory set and generally does not require adjustment for
moulding full range of thermosetting resins. The lower piston is shaped
so that the mould (containing the sample) has bevelled edges to avoid
tearing the polishing cloths. The upper piston in the mould is removable
so that the samples and thermosetting resin can be introduced.
The moulding time and temperature are set on the timer and temperature controller. Both parameters can be set for the required auto moulding cycle. A water inlet and drain is located on the rear panel so that the mould can be rapidly cooled after the cycle. The moulding cycle is activated with the START CYCLE button.
 |
The moulds are interchangeable and this machine can be rapidly converted
to produce a different block diameter. Three metric mould sizes 25, 30,
40mm diameter and three inch mould sizes 1in, 1 1/4in, 1 1/2in diameter
are available. The moulds are supplied complete with matching pistons
and locate in a surrounding conducting block. 4/250 Watt cartridge
heaters and cooling water channels are embedded in this block for rapid
heating or cooling of the mould.
 |
|
A wide range of thermosetting resins can be used with the press. The
most commonly used resins are phenolics and epoxies. In general the
moulding pressure does not need to be altered for the different resins;
it is only necessary to change the moulding time.
