Constant Volume Sample Cutter - Mooney
Volumetric die cutters for preparation of Constant Volume Specimens for Mooney Viscometer


Standards the instrument complies with:   
ASTM D1646;   ISO 289-1;   ISO 289-2;   ISO 289-4;    

Overview 
Preparation of specimens with constant volume for Mooney Viscosity tests ensures high repeatability of results and eliminates the manual preparation operation.

The machine produced by Gibitre Instruments allows for rapid preparation of specimens with standardized volume by also making the central hole for rotor insertion.

The new construction of the machines, with an open structure in the front side, makes it possible to place and cut pieces or strips of raw compound even of large size.
The front protection screen of the pneumatically activated machine automatically descends before the start of the cutting operation to ensure the safe operation of the machine in accordance with CE safety requirements.
The cutting mechanism adopts a double-action piston to press the compound to the required thickness and subsequently activate the cutting die to obtain specimens with the required volume even with compounds of high hardness.
The machine's construction methods do not require the use of cutting planes and ensure easy extraction of the specimen

The specimens produced have the volume required by ISO 289 and ASTM D1646 standards (adjustable from 12 to 13cm3).
The machine is supplied with the default setting that allows producing specimens with a volume of 12.5 cm3.
However, the machine can be adjusted to produce the desired volume between 2 and 15 cm3.


Key Features 
• Preparation of specimens in accordance with ISO 289 and ASTM D1646.
• Ease of use
• Pneumatic action safety door to ensure total operator safety
• Solid steel and aluminum mechanical structure and 1200 kg pneumatic piston to ensure perfect specimens even with hard compounds
- C-frame construction to allow cutting of even large rubber pieces without prior preparation
- Micrometric adjustment of piston displacement for adjusting specimen volume


Sample Volume for Mooney Viscometer 
According to ASTM D1646 : "The test specimen shall consist of two test pieces of the material being tested having a combined volume of 25 cm3. This volume is approximately 1.5 times the volume of the test cavity (1.45 times for small rotor, 1.67 times for large rotor) and will ensure that the cavity is completely filled."

The standard setup of Gibitre Volumetric cutter produces each sample for mooney test with 12.5 cm3.
At order time you can request a custom setup to produce samples with a volume between 12 and 13 cm3.



Puncher for Hole for Mooney Sample  
A puncher, incorporated in the instrument, permits the central hole to be made in the lower sample for the Mooney viscosity test.
The pneumatically-activated safety panel ensures the conformity of the instrument with CE safety requirements.


Safety devices 
The instrument is equipped with:
• Pneumatic activation of the safety protection screen
• Safety switch, which prevents the activation of the piston if the Safety Protection Screen is not closed.
• CE Labelling


Development and production 
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.
