Hanatek Advanced Coefficient of Friction Tester (AFT)

As well as displaying the dynamic and static friction values for the material, the instrument also allows for the frictional profiles to be stored and referenced against new tests. This industry leading feature greatly assists in relating the feed and running speeds to a products surface coefficient of friction.

Optional extras are available to measure peel strength, blocking of films / coated cartons and tear strength.

Friction Measurement

is the initial force required to make two surfaces move interdependently of each other.

Dynamic Friction:

The force required to maintain the movement between two pieces of material

How is friction measured?

A sample typically 63.5mm² with a known mass typically 200 grams, acting over the test sample is run across another sample at a pre determined speed.

Normally this is a face to face test, however a test against another material such as aluminium is sometimes done.

The test parameters are specified in ASTM D2534,  ASTM D1894, ISO 8295, ISO 15359, and TAPPI T549.

Hanatek Advanced Coefficient of Friction Tester (AFT)

• Automated sled lowering with adjustable dwell time which gives much more accurate & repeatable static slip results
• Fixed link between the sled and the load cell, intimating the errors in friction from pulley wheels or cords associated with many other friction measuring instruments
• Statistical & graphical analysis of test results which can be printed or saved as PDF for easy reporting
• Create & store electronic references for future comparison
• Easy loading sled for measuring films or the standard sled for thicker materials such as carton board
• Pre-loaded with ASTM / ISO / TAPPI slip test methods

Touch Screen User Interface

The Hanatek Advanced Coefficient of Friction Tester (AFT) uses an intuitive touchscreen making it easily accessible.

Research and Development tool or Quality Assurance instrument

This flexible instrument can be configured for quality or research use.

Other tests possible with the Advanced Friction Tester

Measure the forces required to close filled cartons.

This test ensures that carton based packages can be stacked and displayed correctly. Cartons must also be properly closed to ensure that any secondary process such as film wrapping can be performed.

During storage, films, labels or cartons can inadvertently block together making them difficult to separate and feed into finishing or packing lines.

• Measure the force required to separate blocked samples
• Full testing and sample conditioning instructions
• Test to international standards

Optional attachments transform the AFT into a precision peel test instrument, accurately measuring the force required to separate glued or laminated films, tapes, labels etc.

• All tests are to FINAT international standards
• T-Peel, 180º peel or 90º peel tests
• Graphical on-screen instructions
• Force curves and statistical analysis

Optional tear strength attachment allows the user to measure and control tear strength to international standards.

• Trouser Tear method
• Full graphical instructions and sample templates

Additional attachment to remove uncertainty in measurement of paper and board.

• Utilises the unique Hanatek sled lowering system to remove placement errors
• Guidance system ensures that the sled is kept parallel with the measuring plate
• Sample preparation system eliminates errors caused by sample contamination

Detachable heated bed can be added to test frictional characteristics at elevated temperatures up to 110º C.
