Tension Fixtures

Tension fixturesTension testing methods involve pulling, extending or stretching the sample. In most cases it is quite difficult, if not impossible, to consistently grip a food sample during a pure pull-type tension test without causing a false failure point. This is sometimes overcome by forming the samples into a “dog bone” shape so that the cross sectional area in the middle of the sample, is smaller than the cross sectional area of the part that is being gripped.

Tension Fixtures

Some products such a stick chewing gum, restructured deli meats and cheeses, can be successfully tested for their elasticity with tensile testing and sensitive fixtures.

Extrusion and extensibility testing fixtures use the machine in compression mode, but the fixture stretches the sample to put it in tension. These fixtures are often used for bakery industry tests, measuring burst strength or adhesion and stickiness.
FTC also has a range of dough and bakery industry fixtures specifically for this type of texture analysis.

FTC offers several tensile grip designs to accommodate the applications of our customers. It is not uncommon that a food texture system, or universal testing machine (UTM) will find good use in the food packaging arena when it comes to tensile testing (e.g. peel).

My first contact with FTC was through buying texture analyzer equipment as my area of interest is Rheology. We faced a problem operating the appliance. The company tried hard to help us through the internet, but the University thought it was better to send me to the company branch located in England. I received a highly advanced training course for 10 days free of charge. They provided me with programs that operate the equipment along with the information needed.

It was a great effort and outstanding support. I would like to thank Shirl Lakeway and FTC for providing me with this opportunity and for his continuous help. Finally, I encourage researchers who are interested in the physical properties of foods and dairy to choose FTC as it is a respectable and dependable company and offers the best deals concerning prices and training with different languages, such as Arabic for the Middle East.

I have found FTC to be an excellent partner for our company. In particular, it has been especially gratifying to work with Shirl Lakeway. Both creative and accommodating, he worked very hard with us to develop our projects.

I appreciate his commitment to our joint efforts and his open-minded approach. He and FTC have been exceptionally helpful.

I have been using the TMS-Pro mechanical tester in our undergraduate biological materials property course for the past 3 years. The simple setup and operation of the TMS-Pro allows my students to focus on learning the theoretical underpinnings of mechanical properties instead of fighting with a finicky test system.

An added bonus is working with Shirl and his amazing team at Food Technology Corporation. They respond almost immediately to questions and inquiries and are always friendly and helpful.
