Automated Tensile Tests on Plastic Films

roboTest F robotic testing system for tensile tests on films

Quality control is imperative in the manufacturing of plastic products, such as films. In order to make materials testing in the manufacturing process efficient and safe, ZwickRoell developed the roboTest F robotic testing system.

  • The testing system is comprised of an AllroundLine testing machine with extended test area.
  • Specimens for tensile testing are fed into the system by a specimen magazine that holds up to 200 specimens.
  • The magazine consists of a base and a revolving chain with grippers for gripping the specimen.
  • These grippers vary depending on the specimen type and shape. This means that films and textiles of various dimensions can be tested by the same system.

In addition to a medium-term reduction in testing costs, this system offers other benefits, which include error-free testing.

"Test results are highly reproducible because operator influence is eliminated. The entire test is logged by the software and the test results are transferred automatically and accurately to the database,"

explains Robert Kaifler, Product Manager at ZwickRoell. Furthermore, the system is compact, requiring little space and is therefore an ideal way to upgrade an existing ZwickRoell testing machine.

Manual tests can be run at any time by simply removing the handling system. The system can also automatically determine the specimen thickness of the film, for example, and identify the specimen using a unique barcode. The test results can then be sent by SMS or email. ZwickRoell is an expert in robotic testing systems with over 25 years of experience in this field and has installed more than 350 systems in a wide variety of industries across the globe.
