The standard feeding method is by dropping samples into a vertical channel which has an opening to release each sample onto the testing table. The required sample size should be 36-42 mm in diameter and 6 mm in thickness. The hardness tests are carriedout according to the standards that a distance of 12 mm is kept from any measuring point to the sample edges and a distance of 6 mm is kept from any measuring point to the next point. Each sample will be carried out 3 hardness tests.

• The feeding channel can accommodate maximum 50 pcs of samples per cycle and during the testing process, more samples can be fed into the column.
• The optional table-feeding system is available (HDA120).
• The testing environment should have temperature at around 20-25°C.
• Use of high performance components like FESTO pneumatic components, Schunk grippers and Balluff sensors.
• Optional sorting system (good bad classification) at exit.

• Hardness test conforms to ISO 7619 and ASTM D 2240.

•  Each sample is carried out for 3. The default measuring time for each test is 3 sec and the time is adjustable from 0 to 99 sec.

• Using the Bareiss “digitest II’ as the hardness testing system. The hardness accuracy is ±0.5 Shore A
• As the sample is dropped onto the testing table, it will get transported to the first testing position and the rest of the subsequent testing positions automatically. Each testing position is programmed to ensure the tests are done on the right locations of the sample.
• A hardness test will not be performed on a vacant slot of the testing table.
• Individual test model is available.
• Load sustainable testing table and all other mechanical component

• Density test conforms to ISO 2758 (Hydrostatic Method)

• Using KERN/Sartorius precision balance (upgradable to Mettler Toledo)
• Reading accuracy from 1.0 to 0.1 mg. The balance can be calibrated by dead weights
• Incorporating a damper system to counteract vibration
• Automatic water refill when empty
• Separate grippers to handle wet and dry operations to avoid water containminations
• Dry and wet tests in the ration of 1:2 to remove excessive bubbles attaching to the sample
• Discharging the samples according to the test results

•  Siemens SPS with large 9″ touch panel

•  Automatic data export through ethernet interface
•  The data from the HDA150 can be transmitted by a simple protocol and send to a data system
• Display of measurements on the touch panel
• Multi-languages

• Range of application

  Hardness and density measurements on soft rubber, natural rubber products, etc.
