The Gibitre Instruments machine, manufactured in accordance with international standards, performs cyclic stress resistance tests on vulcanized rubber specimens at a controlled temperature.
The instrument allows for tensile fatigue testing and flexural fatigue or crack propagation testing using a De Mattia specimen, in accordance with ISO 132, ISO 6943, ASTM D430-B, and ASTM D813 standards.
Why buy it: the climate chamber with integrated refrigeration unit allows testing from -40 to +200 °C; the window with LED lighting facilitates sample inspection during testing; the 12-position specimen holder supports full test sessions; the counter-rotating specimen holders minimize noise and vibration; CE marking.
Parameters are fully adjustable according to the method: frequency 60–300 rpm, stroke 0–60 mm, distance between clamps up to 100 mm, and number of cycles up to 1,000,000 with automatic stop. Dedicated accessories include a specimen notching device and molds for preparing standard-compliant specimens. A solid choice for those seeking reliable instruments for measuring vulcanized rubber materials to verify fatigue resistance and crack propagation under controlled conditions.
The instrument is built according to International Standards about fatigue, which describe test methods for the determination of the resistance of vulcanized rubbers under repeated deformations. This instrument permits to perform:
• Flex cracking/crack growth test
• Tension fatigue test.
According to test specification, the instrument can be easily adjusted by setting
• Test frequency (60 to 300 rpm)
• Test stroke (0 to 60 mm)
• The distance of the grips (up to 100 mm)
• The number of cycles before automatic stop can be set (up to 1.000.000)
The sample holding system is located in a Environmental chamber which permits to set the temperature between -40°C and 200 °C.
The environmental chamber is fitted with inspection window and internal led lighting which permit to inspect the sample without opening the chamber.
The instrument produced by Gibitre uses a Refrigeration Unit to reduce the temperature.
The use of the refrigeration unit, compared to cooling by liquid nitrogen, allows to:
• heck the test temperature perfectly, avoiding oscillations that may alter the results.
• Carry out long-term tests without risking to end the liquid nitrogen supply before finishing the test
• Eliminate the hazards related with manipulation of nitrogen
The instrument is controlled using a touch screen display which permits to set the oscillation frequency, the number of cycles and the test temperature.
The sample holder permits to test 12 samples simultaneously.
The exclusive movement system with both sample holders moving in opposite directions ensures extremely low levels of noise and vibrations.
According to test specification, the instrument can be easily adjusted by setting
• Test frequency (60 to 300 rpm)
• Test stroke (0 to 60 mm)
• The distance of the grips (up to 100 mm)
• The number of cycles before automatic stop can be set (up to 1.000.000)
Mould for De Mattia dynamic tester according to ISO 132, ASTM D 430-method B, DIN 53 522 standards.
The piercing tool allows to realize the standard notch to carry out crack-growth tests.
The instrument is totally developed and produced in the plant of Gibitre Instruments in Italy.
All the mechanical parts are produced in the company workshop using modern CNC machines.
Components and sensors from well-known brands are selected in order to ensure the maximum reliability in the measures
Internal trained personnel takes care of all the production stages: assembly, start-up, calibration, packing, shipment and installation.
The calibration is performed with reference to the requirements of ISO 132 standard.
The service includes:
• Ordinary maintenance of the instrument
• Calibration of the oscillation speed.
• Calibration of the dimension of the templates.
• Calibration of the temperature inside the environmental chamber at 4 temperatures (for flexometers with environmental Chamber)
• Issue and e-mail shipment of the Calibration Certificate with traceability to primary standards.
• Safety protection doors fitted with safety switch.
• Safety Push-button
• Digital Motor controller with torque overload control.
• CE labelling
