Grippers

Mechanical Gripping System for Tensile Testing

Mechanical Gripping System for Tensile Testing
Mechanical grips for flat and/or round specimens operating on the screw-clamping principle, made of quenched and tempered 39NiCrMo3 steel, with a burnished surface finish suitable for fatigue testing with loads up to 20 kN and a knurled clamping system.

Maximum grip width: 30 mm.

Equipped with:

– 2 pairs of knurled plates for flat specimens from 0 mm to 8 mm;
– 2 pairs of knurled plates for round specimens from 6 mm to 12 mm.

These clamps are suitable for use in a climate chamber and for performing tensile tests on polymer or elastomer specimens.

We have developed systems for flexural testing up to 100 kN.

Hydraulic Gripping System for Tensile Testing

Self-centering hydraulic wedge grips, constructed from a single piece of steel, suitable for tensile and compressive loads and for load cycles around zero with forces up to 100 kN.

Equipped with:
– 2 pairs of wedges for flat specimens from 0 mm to 10 mm;
– 2 pairs of wedges for cylindrical specimens from 10 mm to 25 mm.

Fatigue Testing System for Hip Prostheses

A system designed to perform static and fatigue tests on hip prostheses, consisting of:
– a lower mounting element onto which the prosthesis stem will be cemented;
– an upper loading element with two orthogonal, low-friction slides;
– a thermostated liquid chamber into which the entire system is inserted: this allows tests to be performed in physiological solutions or other liquids, ensuring that the temperature remains within ranges close to ambient and body temperature.

Three- and Four-Point Bending Test System

A system that allows for three- and four-point bending tests with adjustable supports and punches.
Made of high-strength steel, it features a graduated scale on the sliding bases that allows for the positioning of the supports and punches. The rollers are interchangeable and made of high-hardness steel.

Key features:
– Maximum applicable static and dynamic forces: 10 kN;
– Center-to-center distance for punch adjustment range: 40 to 200 mm;
– Contact roller width: 50 mm.

We have developed bending test systems capable of withstanding forces up to 500 kN.

Compression Plate System

Circular compression plate system made of 38NiCrM3 steel, complete with a spherical joint to compensate for minor misalignments.
The upper plate with the spherical joint is directly connected to the cylinder rod.
Four spring rings hold the joint assembly in place.
The lower plate is connected to the load cell, which in turn is mounted on the base of the frame.
The diameter of the compression plates is 125 mm.

Gripping Device for Connecting Rod Tests

The equipment consists of a force-closing frame and two mechanical grips that replicate the operating conditions of the connecting rod, ensuring proper mating during service.

A forced lubrication system is therefore provided at the connecting rod head; lubrication at the connecting rod foot, on the other hand, will be by gravity.

Italsigma designs and manufactures custom testing systems to support companies, research centers, and laboratories in the development and validation of their products.

Every industrial sector has specific requirements for testing, simulation, and performance verification. That is why Italsigma develops customized testing machines,
