Micro-IRHD Laser Revolution

Micro-IRHD Hardness tester with laser centring device and rotating sample holder for the automatic serial measure of O-ring and small rubber parts




 
Description 
The instruments is supplied with laser centring device and motor-controlled sample holding disk for the displacement of the parts to be measured.
The sample holding disk moves each test piece under the laser centring tool and then places the optimal test point of the part under the micro-irhd testing unit.
The positioning and hardness measuring operations are performed automatically for all the parts placed on the sample holding disk across the laser reading line without intervention of the operator.

Applications of the instrument 
The instrument permits to perform the serial measure of micro-irhd hardness of O-rings and small parts eliminating the human influence in the sample positioning.
The instrument is useful for:
• Product approval or Quality Control tests which require the repeating of the tests on statistical basis
• Mold approval tests
• Process capability analysis
• Testing of small parts difficult to be centered manually
O-rings or small parts with a thickness between 1 and 20 mm can be tested.
The laser testing process can be stopped to perform tests with standard samples.

Management of Test Results 
The results and test curves of all the tests carried out are saved in the Gibitre SQL database and are available through the Datagest program.

Datagest is the Laboratory Information Management System (LIMS) which is always installed in combination with all Gibitre instrument-control programs.
The program is the collector for all the test result produced with the instruments connected and permits to manage the common Archives used by the instruments (Product List, Customer List, Tolerance limits, Order List, etc)

Industry 4.0 integration 
The instrument and the software have been specifically developed to optimize integration with other environments.
The database in SQL format and the Gibitre_Company_Connect program allows you synchronize your company management software with Gibitre database and to speed up the identification of the tests and to use bar-code readers or similar devices.
The automatic logging service permits to send alarm information to the cloud-service platform of Gibitre Instruments in order to optimize the reaction times of the Service Support.

Test report 
Can be printed or saved to pdf in one of the available languages. The format of the Test Report can be customized by the user.

Example of Test Report (Micro IRHD)

Example of Test Report: IRHD+Hysteresis
Tolerance Limits 
The Datagest program allows you to define specific tolerance limits for each Product, Customer, Test Procedure and Aging Treatment.
For each result to be calculated, tolerance limits and alarm limits can be defined.
The comparison between the results and the tolerance limits is carried out automatically at the end of each test: the test results are colored (Green, Yellow or Red) based on the outcome of the comparison with the limits.
The outcome of the check is saved in the database together with the results.

Statistics of ongoing tests 
The programs automatically process the statistical analysis of the tests in progress by calculating:
• Maximum
• Minimum
• Average
• Median
• Standard deviation
• Cp
• Cpk
In addition, the Gaussian curve relative to the results is shown together with the tolerance limits to immediately highlight the progress of the tests in progress.
The Datagest program allows you to process more detailed statistics related to the saved results and to represent X and R Charts by grouping data by order, batch, batch, date, etc.
Technology of Micro-IRHD device  
The micro-irhd testing units produced by Gibitre measure the force applied to the sample using a load cell.
This technology, widely used for the hardness testers for metals, permits to eliminate the effect of friction in the application of the force and improves the test repeatability.

Characteristics of the laser centering device and of the sample-positioning system 
The laser sensor used is class 2 type and has 0.002 mm reading resolution.
The sample positioning disk permits to set the position of the test piece with 0.005 mm accuracy.
The combination of accurate measuring and sample positioning devices ensures a very high repeatability of the results obtained even when very small parts are tested.

Safety devices 
The instrument includes safety devices to eliminate potential risks during the automatic working.
• Test stops in case of incorrect sample centring
• Test stops in case of overload of the indentor
• Test stops in case of missing laser reading or sample positioning reading.

The instrument is supplied with CE Labelling

Which is the difference between Shore A and IRHD Hardness test results?
Test results of tests performed with IRHD (ISO 48-2) are are similar to the ones obtained with Shore A test (ISO 48-4), especially for low hardness. However, they are not strictly the same. Indeed, depending on the shape of the part, we can regularly notice 2 to 5 points hardness difference between Shore A and IRHD measurement done on the part. This difference can even be extended to 10 points difference in extreme cases. In general, IRHD results are lower to Shore A results. That is why it is common to use “75 Shore A compounds” to obtain “70 IRHD part”. For example, parts moulded with a “70 Shore A compound” can give finished parts with a hardness from 62 to 65 IRHD, and therefore out of the 70±5 IRHD tolerance.
?
How should I correct the Shore A hardness of the compound to obtain the requested IRHD Hardness of my finished part?
The correct method to obtain the expected result in terms of IRHD hardness is to measure the result obtained at the end of the transformation process, compare it with the tolerance limits and correct the compound formulation by the number of points necessary to 'center' the result. This operation must be carried out for each mixing recipe and for each transformation process.
