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.

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.

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.

To check the specific gravity of rubber and other elastomers, we offer technically advanced “HIROSHIMA” Specific Gravity Balance. Its faster and accurate readings can give results in about half a minute.  It is provided with an anodized scale with a balancing arm at center that stands vertical on the base plate and is printed with specific gravity (SG). To reduce friction, the scale is supported with two jewel bearings.  The short length of the yarn is attached to one pin of the arm and the long length of the yarn is attached to another. To immerse the second pin in water a tall transparent jar is used. The pointer that is attached to the other end of the arm indicates the specific gravity of the concerned sample. The tester is also provided with a sliding weight for balancing different weights of sample in initial stages. The specific gravity tester is available in different modals. 

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.

Construction:
The main part of the equipment is a metal based hollow cylinder having an internal diameter of 18” and length of 18” and is opened at both ends. To ensure that the light is distributed constantly around the circumference, the 500 W MBTL fading lamp is mounted in the centre. At the base an hour meter with buzzer and hour totalizer are fitted.
Moreover to regulate the temperature as it can rise up to 800 C, arrangement for continuous cooling is done along with water flow that is supplied via a horizontal pump and water tank.

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.

Our range of hardness testers conducts tests as per the IS 7888 – 1976 that is concerned with methods of tests for Flexible polyurethane Foam. To check the indentation hardness of the foam blocks, they are subjected to pressing by a circular indentor at a particular speed. Then the force that is required to press to a specified percentage of initial thickness is determined.      The load stand is made of premium quality cast aluminium and consist od numerous holes to ensure quick escape of air during compression. For perfect and corrosion resistant finish, the stand is coated with dark enamel painting and bright zinc or chrome plating.
