Rheocheck Profile Moving Die - PC


Gibitre MD Rheometer measures the cure characteristics of a rubber compound in conformity with the international standards.
The measure of the vulcanisation is carried our by measuring the change in the mechanical characteristics of the sample. The instrument permits to apply a cyclic strain to a test piece and to measure the associated force. The test is carried out at a constant temperature and the measure of stiffness recorded continuously as a function of time.

Instrument Characteristics

Pressurized Testing chamber
Torque measurement reaction transducer positioned in the upper test chamber to minimize the influence of friction and vibrations.
Easily accessible test area with transparent safety panel and safety lock. Test chamber in compliance with international standards.
Direct test chamber heating controlled by thermoregulators with PID microprocessor with O.1 °C accuracy. Easy change of oscillation angle of lower die.
Control system for compressed air pressure, cleaning and lubrication. Designed for eventual application of a fume aspiration system.

Volumetric die cutter.
Polyester or Polyamide film for test execution

Gibitre-RheoCheck Software

Graphic representation of the following curves: Elastic (S’), Viscous (S’’), Complex (S*), storage shear Modulus (G’), loss shear Modulus
(G’’), Curing Speed, Tan-Delta, upper and lower test chamber temperatures.
Display and printing in different colours of the relative test curves for rapid test identification. Customizable test procedure with possibility of selecting up to 20 test results to be stored and printed (see table).
Checking of whether results comply with tolerance limits and relative statistical analysis (Mean, St. Dev., Max, Min, Cp, Cpk, X-Chart, Gaussian Distribution).
Automatic generation of tolerance limits from statistical analysis (mean and standard deviation) of stored results.

Instrument Characteristics

Double screw structure with recycling of ball-bearings designed for the application of load cells up to 20 kN. A wide range of Load cells, operating in traction and compression, can be installed on the instrument.
Auto-detection of the load cell installed.
Measurement of the crosshead displacement with 0.0025 mm resolution.
Advance speed can be adjusted from
0.1 to 1000 mm/min.
Safety limit switch for adjustment of the slide stroke and automatic return on termination of the test.

Gibitre-TensorCheck software

The software includes a wide range of predefined test procedures in compliance with international standards (traction, compression, peeling, hysteresis, flexion, etc.) and the possibility of creating fully customized test procedures for non-standard tests.
Direct sample thickness acquisition from digital centesimal thickness meter connected with the instrument (optional) and automatic calculation of the cross-section depending on the type of sample selected.
Display and printing in different colours of the relative test curves for rapid test identification.
Checking of whether results comply with tolerance limits and relative statistical analysis (Mean, median,, Max, Min, Cp, Cpk). Compari- son of test results with the tolerance limits set for the product under test.


Stretch gauge for differential extension measurement with resolution 0.01 mm.
Wide range of load cells operating in traction and compression up to 20 kN full scale.
Thickness meter for direct acquistion of sample thickness in compliance with ISO 4648 and ASTM D 3767 standards.
Pneumatics grips with regulation of closure pressure.
Wide range of grips for traction, compression, peeling, stress relaxa- tion tests for standard or customer-defined tests.
Thermal Chamber for the performance of tests with controlled temperature (between -35°C and +250°C).
Protection hatch.

Multi-Unit Automatic hardness testing system


Multi-Unit Automatic hardness testing system has been designed for labs, which need to perform hardness tests according to different hardness scales.
The hardness testing unit to be used must be placed in the front position by rotating the top part of the support. The rotating system permits to interchange the test unit within a few seconds. No dismounting or re- placement of delicate parts and no specific training are required to per- form with full safety this operation. This solid technical solution is ideal even in the case that the change of unit must be done many times in the same day.
The solid construction of the instrument, the high quality sensors and the lifting system with ball screw makes it ideal both for research purposes and for heavy-duty production control.

Instrument Characteristics

The instrument can be configured according to the needs of the customer: up to 4 units can be mounted on the same support. The available hardness testing units are:
Shore A, Shore D,
Shore A0, Shore 00, IRHD-Micro,
IRHD-Normal, IRHD-Hard, IRHD-Low.
The support of the unit is configured for the further installation of units in case free positions are available.
The Multi-Unit Automatic hardness testing system is composed by the following parts: mechanical structure, Rotating hardness testing unit support, Hardness testing units, Sample Holder with motor- controlled rotation , motor-controlled-Lifting System with ball screw, Electronic card.
All the parts, which compose the instrument, have been specifically designed for easy interchange in case of failure.

Instrument Control

The Multi-Unit Automatic hardness testing system can be controller both with Gibitre Hardness Software and with Gibitre Electronic Console.

About us

Company details

Gibitre was founded in 1979 and as a company dealing with a wide range of activities in the rubber industry including rubber compounding, rubber moulding and rubber control instruments production. Gibitre Instruments was created as a separate company in 2001.

The aim of Gibitre Instruments S.r.l. is the development, production and marketing on world scale of a wide range of instruments for laboratory rubber and plastic testing. The company provides maintenance and calibration after-sell services for the complete range of instruments produced.

The goal that the company wants to achieve is to improve the position of recognized technological partner for all issues related with control of rubber and polymers.
The tools for the persecution of the goal are:
Development of internal know-how by means of:
- Cooperation agreements with key-customers
- Participation to International test programs
- Participation to technical commission for the development of international test standards.

Improvement of the products by means of:
- Progressive increase of the range of instruments and options offered
- Continuous upgrade of the products to incorporate technological improvements and standard developments
- Progressive production costs reduction to keep the present optimal ratio cost/ performance

Continuous improvement of the service by means of:
- Progressive reduction of the delivery time for instruments and spare parts
- Progressive reduction of the technical intervention time
- Improvement of instrument construction to simplify maintenance
- Development of innovative forms for technical assistance/calibration
- Increase of the number of products included in the list of official ACCREDIA calibration
