Radial Force & Hoop Force Testing - Blockwise Engineering

Blockwise offers complete radial force testing systems comprising a tensile testing machine and one or more low-friction radial compression stations, in various size ranges. Our radial force testing equipment is used and trusted at over 100 medical device companies, universities, and regulatory agencies. Our partner Zwick/Roell also offers complete systems based on Blockwise compression stations.

We also offer our radial compression stations as "fixtures" that you can attach to your tensile testing machine, such as Zwick, ADMET, Instron, Tinius-Olsen, MTS, etc.

Tensile Testing Machine for Radial Force - Model TTR2

The world’s easiest-to-use radial force testing machine has purpose-built software with all the features you need and none that you don’t need. Beginners and occasional users have no problem quickly getting results. Calibration is an easy 2-minute task. Various Blockwise radial compression stations may be mounted on the TTR2 to form a complete radial force testing machine. Compression stations may be easily removed and replaced, and are chosen based on the size of the device to be tested.

Compression Stations as “Fixtures” for Your Tensile Tester

Most types of Blockwise metal-die radial compression mechanisms can be attached to your tensile testing machine. Your choice will depend on the maximum diameter and length of your stents. To obtain the lowest friction and lowest purchase cost, choose the smallest mechanism that accommodates your size range. All of these mechanisms feature very low friction, linear relationship of stroke to diameter, and optional heating / temperature control.
