Metal Testing Machines{Strength of Material (SOM) Lab Eqp's}

Our Torsion Testing Machine for Wires & Cables promptly determines the number of twists required to fracture a wire sample. The machine is available in two models, one for testing wires in the range of 1-5mm and the other for 4-10mm length. The machine generates an output of 30, 60 or 90 rpm with the help of gear box connected with a motor. The revolution counter shows the number of twists and stops when the sample fails. The wire is held between a rotating and a non-rotating chuck whose distance lounge between 1-500mm in length. Operated on 400/440 volts, 3 phase A.C supply, this machine can test wires ranging from 1-10 mm in length.

We are offering Erichsen Cupping Testing Machines, which are manufactured to undertake Erichsen cupping tests on metals. These machines works faster as they are manually operated and quick clamps help in their smooth working. Other technical specifications are:

• Width of sample: 70-90 mm
• Thickness of sample: 0.1-2 mm
• Least count: 0.01 mm
• Overall Dimensions ( approx): 450x500x500 mm
• Net weight (approx): 20 kg

We provide Rotating Cantilever Fatigue Testing Machines, which are used to ascertain the fatigue strength under reversed bending stresses. The machine helps to check the fatigue life & location of fatigue failure of metal specimens, subjected to alternating stress cycles. Our range of Fatigue Testing Machines is well-known for its features like reliability, durability and effective performances. We ensure that our machines support as a cantilever, where dead weights at the free ends through self aligned bearings allow vertical loading and rotation of the specimen. Furthermore, we use a counter balancing balancing lever system to balance the dead weight of the loading assembly. There is an induction motor to rotate the specimen and a cut off switch is used to stop the machine when it fails. A counter which is attached to the extension of the motor shaft through reduction gear, records the total counts of cycles to failure.

TECHNICAL SPECIFICATIONS:

We manufacture Rockwell hardness testers & Rockwell Cum Brinell hardness testers that are used for measuring hardness of all kinds of alloys and metals, whether hard or soft, round or flat or irregular in shapes. These machines are as per IS:1586- 2000 standards and are also available in motorized versions. Such products find their applications in tool rooms, laboratories, Heat treatment shops, inspection departments, research & development departments, educational institutions and foundries.

Following are some of the specifications of this range of machines:

• Automatic weight selection with automatic zero setting dial gauge
• Test height x Throat is – 215 x 132 mm
• Rockwell test minor load is 10 KGF & major loads are 60,100,150 KGF
• Extra test height & throat of 295 x 148 mm
• Rockwell hardness scales such as HRB, HRA,HRC, etc. is obtained by
  using different types of indentors ( Diamond / Ball ).

We manufacture Pendulum Impact Testing Machines, which are used for conducting 1Z0D, CHARPY and IMPACT TENSION tests. These test methods adheres to IS 1499-959, IS 1757-1961 and BS 131 part 2 % 3, IS 1598-1960, BS 131 (Part 1) and ASTM E 32-47T. The difference between the height of the drop before rupture and height of the rise after rupture shows the impact energy absorbed by the specimen and is reflected on the dial scale.

SALIENT FEATURES :

• Safety guards for Protection
• Release of Pendulum by Hand operation
• Braking Arrangement provided to arrest the swing of pendulum after specimen rupture

CAPACITY 30 KgM / 300 Joules

We manufacture Universal Testing Machines, which are fabricated for testing metals and other materials under compression bending, transverse, tension and shear loads. The testing of standards specimens and structure is possible due to large effective clearance between columns. Other specifications of these machines are as follows:

• Loading Accuracy as high as (+) 1%
• Straining at variable speeds to suit a wide range of materials.
• Robust staining frame of an extremely rigid construction
• High reading accuracy due to large size and design of dial.
• Wide range of standard and special accessories, including load stabilizer
• Easy change from plain to threaded and screwed specimens.
• Motor driven threaded columns for quick effortless adjustment of lower
  cross-head-to facilitate rapid fixing of test specimen.
• Ease of operation by simple controls.
• Safe operation ensured by means of safety devices
