Hanatek AFT Advanced Friction Tester

Advanced Friction Tester (AFT)

  • Static and dynamic coefficients of friction
  • ‘T’ peel test
  • Tear strength test
  • Blocking tests
     
Description

The Hanatek Advanced Friction Tester is the most comprehensive tool available for measuring the coefficient of friction of plastic film, printed cartons, packaging substrates or paper.
This flexible instrument can also be used to measure and display the frictional values of any flat surface including plastics textile, coated metals and leather.

In addition to providing static and dynamic slip values for a surface, the instrument allows the full friction force output to be displayed, stored and compared. This unique ability helps a manufacturer to relate the feeding and running speeds of a product to its surface characteristics.
The friction tester is available with optional extras to measure peel strength of adhesives, tear strength of substrates and the blocking of plastic films and coated cartons.

Measuring Friction

The Hanatek Advanced Friction Tester measures both static and dynamic coefficient of friction.

Static Friction:
The initial force required to make two surfaces slip against each other.

Dynamic Friction:
The ongoing force required to maintain movement between two surfaces.

How is friction measured?
A sample of 63.5mm² with a weight acting over the entire surface area is run over another sample at a given speed.

This is typically a face to face test.

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

Advanced Friction Tester Features:

Automatic sled placement with variable dwell times give more repeatable static slip results

Sled is positioned on lift pins

sled-on-pins-down

Lift pins retract into the instrument and the sled is place in the same position each time

Fixed link between the sled and the load cell means that there are no errors in friction from pulley wheels or cords associated with other measuring instruments
Full graphical & statistical analysis of test results can be printed to PDF for easy reporting

Box Closing Force

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.

Block Testing - Flims, Labels & Cartons

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
