TENSILE TESTING MACHINE

/in /by

DESCRIPTION : Tensile Testing Machine is designed for conducting Tensile & compression test on various products like Wires, Tubes, Sheet material, Textile material, Rubber, Plastic, Cables, Conductors, leather, asbestos paper, Plywood, Metals etc. The force measurement is by pendulum dynamometer system. Force can be applied to specimen by electric motor through gear box and pulleys. The safety control devices are incorporated

RANGE OF EXPERIMENTS :
1. To Perform Tensile Test
TECHNICAL DESCRIPTION :
Test Range : 10 N to 500 N
Elongation Scale Least count : 1 mm
Grip Separation : 25 mm Minimum , 1000 mm Maximum
Load measurement : With the help of a load cell and a digital display
having arrangement to display the maximum load exerted during the test
Elongation measurement : Measured between grips on a scale from 0 to
1000 x 1 mm.
Electric controls : Push button controls for up and down movement and
stopping with The help of contactors. Micro-switches for over-travel
protection, over-load protection. Automatic stopping of motor on failure of
test specimen

ERICHSEN CUPPING MACHINE

/in /by

DESCRIPTION : The Erichsen cupping test is a ductility test , which is used to evaluate the ability of metallic sheets and strips to under go plastic deformation in stretch forming. The test consists of forming an indentation by pressing a punch with spherical end against a test piece clamped between a blank holder and die , until a through crack appears. The depth of cup is measured.
RANGE OF EXPERIMENTS :
1. To Perform Cupping Test
TECHNICAL DESCRIPTION :
Width of sample mm : 70-90
Thickness of sample mm : 0.1-2
Least count mm : 0.01
Overall dimension ( approx.) mm : 450 x 500 x 500
Net Weight ( approx.) Kg : 20
SERVICE REQUIRED : Power Supply : 230v , Single Phase , 50 hz
Foundation As Per Drawing
SPACE REQUIRED : 1 m. ( L) x 1.0 m (W) X 1.0m (H).
WEIGHT : @ 30 Kg

SPRING TESTING MACHINE

/in /by

DESCRIPTION : The spring testing machine has two uprights fixed to a rigid base and three cross heads. The upper and lower cross heads are rigidly attached to the uprights while the middle one is made to move on finely finished gunmetal bearings over the uprights. To the middle cross head is attached the loading cradle where tire weights for loading the spring during the test are placed. The spring for tension test is held on hooks between the upper and middle cross heads while that for compression test is placed on collar between the middle and lower cross heads .Clutch mechanisms are provided to help holding the middle cross heads for fixing the spring

RANGE OF EXPERIMENTS :
1. To determine the modulus of rigidity (Shear modulus) of
the material of the spring.
TECHNICAL DESCRIPTION :
The unit consists of,
Microprocessor based unit
Quick and accurate measurement
Maximum capacity : 20 Kg
Width between columns : 160 mm
Maximum cross head travel : 160 mm
Force measuring resolution 0.01 Kg.
SERVICE REQUIRED : Power Supply : 230v , Single Phase , 50 hz
Foundation As Per Drawing
SPACE REQUIRED : 1.5 m. ( L) x 1.0 m (W) X 1.7 m (H).
WEIGHT : @ 70 Kg

POLDI HARDNESS TESTER

/in /by

DESCRIPTION : Poldi hardness test is a dynamic hardness test and can be used at any stage of processing of metals. The instrument consists of a hardened steel ball of 10mm diameter fixed to a hollow cylindrical casing; a movable plunger is fixed rigidly in the casing by means of spring. A standard test bar is inserted in the gap provided between the plunger bottom and the steel ball. The test bar is hardened for a predetermined value and is tapered for easy insertion RANGE OF EXPERIMENTS : 1. To determine the hardness of a given sample by using poldi hardness tester TECHNICAL DESCRIPTION : Material : ALLOY STEEL EN-8 OR EN-9 Dia : 30 mm Length :85 mm TUNGSTEN CARBIDE BALL : 10mm SERVICE REQUIRED : SPACE REQUIRED : 0.3 m. ( L) x 0.3 m (W) X 0.3 m (H). WEIGHT : @ 3 Kg
