Apex Enterprises, Kandivli, Mumbai

We provide flex tester that is widely used in the rubber
industry. Rubber needs to be checked if it can withstand continuous flexing
without developing cracks, especially for products that are subjected to
repeated flexing. For this the process of flexing is faked in the laboratory
under standard conditions in terms of speed, mode, and degree of flexing, with
the help of our De - Mattia Flex Tester.
 
Our range of “HIROSHIMA”
De-Mattia Flex Tester comprise of a set of grips that can easily hold the test specimens
in two tiers. One end of the test specimens is held in a fixed grip and the
other end in a reciprocating grip in order to reciprocate the flexing and
unflexing actions. It is provided with two fixed grips and one large
reciprocating grip that are placed between them so that half of the test
specimens is flexed and the other half is unflexed at the same time. An
eccentric and linkage mechanism driven by an electric motor through V-belt and
pulleys is used to generate reciprocating motion. The counter indicates the
number of test cycles completed. We also provide Molding dies, jig and punch
assembly and other accessories.

We provide a huge assortment of
abrasion tester that is in compliance with DIN 53516, and ASTM D 5963. This
instrument is very useful in determining the resistance of elastomers with respect to the
loss of abrasion. This instrument can conduct abrasion tests of material prone
to wear and tear during their functioning such as tires, conveyor and drive
belts, shoe soles and others. These products are checked as per the DIN 53543
standard. In this test the abrasion is determined regarding the volumetric loss
of a cylindrical sample, which is
subjected to movement along an abrasion sheet under set pressure, distance and
a constant speed. This tester can conduct comparative measurements on plastics,
chalk, painted surfaces and other similar material.

Our range of Hiroshima
light fastness tester conforms to the Australian AS 2001.4.2 standard
and is appropriate for determining the colour fastness of the fabric
to light. This is done with the help of a 500 W Mercury Ballast
Tungsten Filament Lamp and internally phosphor coated. This light
fastness tester can be used for all types of textile textile with the
exception of photochromatic coloured textiles. To test the fabric or
textile the sample along with blue wool standards is bared in the
light coming from a MBTL fading Lamp. The fastness of the sample is
compared with that of 1 – 8 Blue Wool
Standards.

The Martindale Abrasion
Tester fabricated by us is perfect for determining of resistance of
any fabric to abrasion. This is done by abrading the fabric under
particular conditions against a standard abradant. For this both the
abrading surfaces are kept parallel to each other during the
operation. It provides a regulated abrasion between the fabric
surfaces in a constantly changing direction and at low pressure. For
abrading the circular specimen of fabric, it is kept in a known
pressure under two simple harmonic motions that are right angle to
each other. To inspect the fabric’s resistance to abrasion its
visual appearance or loss in mass of the
specimens is checked out.

Construction:
The tester consists of a
plate that is set into motion by combining two harmonic motions at
right angle by three rotations eccentric pegs. It has a specimen and
abradant holder to mount and abrade the specimen respectively. The
nylon discs supports the plate and its slots locates the eccentric
pegs in. An electric motor, worm reduction gear box, sprockets and
chain arrangements are provided to rotate the pegs, thereby causing
the movement of plates in SHM.
When the plate moves, it
causes the specimen holders to move with the plate in order to abrade
the specimen that is mounted on the metallic discs against the other
sample fixed below the specimen holder. Dead weights can be added or
removed from the specimen holder in order to alter the force on the
test sample. Its counter counts the number of rotation of outer pegs
and stops the motor after completion of the pre-set rotation numbers
automatically.

The package hardness tester is
perfect for evaluating the hardness for yarn bobbins, warp beams and allied
products. Its ball shaped indentation body eliminates the chances of any kind
of damage to bobbins and warp beams. The winding hardness is proportional to
the distance covered by the indentation ball, which is transmit by means of a
movement (r=55 mm). Its operation depends on the material to be tested and a
flat working face is recommended for bobbins with a diameter of more then 400mm.
Our clients can avail the package hardness tester with different indentation
balls of 2.5 Ø mm, 5 Ø mm or 10 Ø mm.
