manufacturer exporters of all type of scientific instruments

We provide fatigue testing machines which is used to test the fatigue strength of materials and to draw S-N diagram by research institutes, laboratories, material manufacturers and various industries. Fatigue testing machine is a rotating beam type machine in which load is applied in reversed bending fashion. The standard 8 mm dia specimen is held in special holders at its ends and loaded such that is experiences a uniform bending moment. The specimen is rotated at 4200 rpm by a motor.

A complete cycle of reversed stresses in all fibers of the specimen is produced during each revolution. The bending moment is applied with a lever system and can be easily changed by moving a weight over the lever. Total number of revolutions at which the specimen fails is recorded by a Digital counter. An interlocking system puts off the motor at specimen failure. Our machine complies with the requirements of IS 5075-1969 Light weight, compact size, simple design.

Some of the salient features of our model are as follows:
• Simple lever system of changing load
• Accurately calibrated as per IS 5075 Calibration in Nm available on request

It is designed to perform tensile, compression, bending and shear tests on most widely varying materials, both in form of test pieces and as finished products. Hardness test on metals can also be performed. The equipment is calibrated in accordance with B.S. 1610 and I.S. 1828-1993. UTM comply with grade ‘A’ of B.S. 1610: 1964 and grade 1.0 of I.S. 1928-1993

The machine consists of Straining Unit, Control panel (Power pack, complete with drive motor and an oil tank, control valve, a pendulum dynamometer, a load indicator system and an autographic recorder

We offer tensile testing machines for extensive applications. Our machines are available in two column construction and are especially designed for conducting tensile tests and elongation of materials like wires, cables conductors, plywood, ferrous & non-ferrous material as per various standards like IS, BS, DIN, ASTM etc. The specimens in shapes of wires, cables, dumbbell, and strips can be tested by selection of appropriate grips. Our machines are capable of giving accurate date on the physical properties of materials in a rapid and simple manner.

Salient Features:
* High accuracy of ±1% as per IS 1828
* Three measuring ranges for accurate testing
* Robust, easy to operate and less maintenance
* Load and elongation recorders
* Varied straining speeds on selection
* Attachments for conducting compression, bending shear tests
* Digital display with data recording printer
* Different range of grips for various materials and shapes
* Incorporate with requisite safety devices

We offer torsion testing machines which are designed for conducting torsion and twist tests on various metal wires, tubes and steel materials. Torque measurement is conducted by Pendulum Dynamometer System. The Torque ranges can be adjusted and can be applied to specimen by geared motor through gear box. Our machines can be customized as per the requirement of customers and are available in three models.

Salient Features:
* Number of twist can be determined rapidly
* Wires from 1 to 10 mm can be tested
* Electrically operated suitable for operate on 400-440 volts, 3 phase, AC supply.
* Available in two models: For testing wires in the range of 1-5 mm range and other 4-10 mm.

Accessories:
* Gear box
* Motor (output of 30, 60 or 90rpm)
* Revolution counter: indicates total twists, and stops counting when the sample fails

Bend Testing Machine
* Bend test on steel wires of major dimensions from 0.8 mm to 5 mm
* Repeat bending of test piece, rupture over a cylindrical surface of specified radius through 90 deg
* Designed with reference to the essential elements given in 1716-1971
* Fixed base plate for conducting bend test on wires
* Machine dispatched in a complete assembled form
* Two Allenkeys for frightening of cylindrical formers carried in the block while a spanner used for frightening    the bolt of the guide arm which slides in the slot, marked in millimeters for adjusting the height.

Torsion testing machine for wires as per IS: 1717

* The wires from 1 to 10 mm can be tested.
* Electrically operated suitable for operation on 400/440 volts, 3 Phase, A.C. supply.
* Available in two models: For testing wires in the range of 1-5 mm and the other 4-10 mm.

Accessories:
* Gear box
* Motor (output of either 30, 60 or 90 rpm).
* Revolution counter: indicates the total twists and stops counting when the sample fails

Torsion Testing Machine for Rods
We offer torsion testing machine for rods by conducting torsion and twist test on various metals, wires, tubes, sheet materials, torque measurement is by pendulum dynamometer system. The torque range can be adjusted and applied to specimen by geared motor through gear box. The autographic recorder detects the relation between torque and an angle of twist on request.

It is designed for conducting Izod and Charpy test. The Test method confirms to IS: 1598-1997, 1757-1973, 1499-1977, 3766-1977 as well as BS: 131-Part 1,2,3 & 4 - 1972. The pendulum is mounted on antifriction bearings. It has two starting positions, the upper one for Charpy and the lower one for Izod testing. One release, the pendulum swings down to break the specimen and the energy absorbed in doing so is measured as the difference between the height of drop before rupture and the height of rise after rupture of the test specimen and is read from the position of maximum pointer on the dial scale.
