Three-stage compression test of a spring coil is shown in this video. The customized stand can program each stage by displacement and force value. For example, the test stand can temporary stops not only at three different depth from the contact point such as 3,8 and 15mm but also at certain force value, for instance, at 5,10 and 25N. The holding time for each stage can be also set individually. The transition of the force value can be shown according to the time or displacement. Hysteresis is depicted in the graph between force and displacement.

This video shows resilience test of a basketball by a customized dual-column test stand and a customized jig with 16mm-diameter. The compressing force becomes bigger if you continue to press the ball. Thus, you need to set up certain displacement value to reverse the motion of the force gauge and observe the relation between force and displacement. The graphing software allows you to graph that relationship and to confirm the transition visually.

In this video, pillow resilient force is measured by a test stand with large table. By setting Length limit, the force gauge automatically stops pressing and starts going back once the force gauge pushes pillow into that depth. The compression force and resilient force of pillow are expressed by a graph on the PC screen.

This is a break strength test of lip balm. By using a customized jig which can press the center of the lip balm accurately and a customized fixture to equip our versatile motorized stands with the stick holder for FRTS, our texture analyzer, this test is conducted easily and precisely. If you use graph drawing software, you can see not only the maximum value at which the lip balm breaks, but also transition of force by time.

The durability of cardboard is getting more important to protect products during distribution, which causes companies value its quality management. For instance, a box-making machine, also known as a carton former, opens the folded carton to make a carton box, however, the machine may shut down due to the variation of force to open folded cartons. Thus, the management and testing of opening force of flat-folded carton is necessary. This video shows how to measure the force when opening the flat folded carton by using IMADA customized attachment and testing equipment. Moreover, By using the graphing software, the transition of the force to open the flat-folded carton can be checked visually.

This is repulsion force test of cushioning material by using IMADA force-displacement analysis unit. The compressing force becomes bigger if you continue to press the cushioning material. Thus, you need to compare the compressing force at a certain compressing distance (displacement). IMADA's force-displaceemt analysis unit enables you to check the transition of the force graphically when the cushioning material is compressed or when it returns to its original shape. It is used for R&D and quality control.

This is simple way of compression test to determine repulsion force of packing material. The compressing force becomes bigger if you continue to press the packing material. Thus, you need to compare the compressing force at a certain compressing distance (displacement). IMADA's force testing system enables you to determine the repulsion force at a certain displacement. This test is used for R&D and quality control.

This is compression test to determine repulsion force of game ball by using IMADA force-displacement analysis unit. The compressing force becomes bigger if you continue to press the ball. Thus, you need to compare the compressing force at a certain compressing distance (displacement). IMADA's force-displacement unit enables you to analyze force transition visually based on a certain displacement when the ball is compressed or when it returns to its original shape. The analysis unit is widely used for R&D and quality control.

This is simple elasticity force test of ball. Elasticity is determined by compression test, however, you need to fix the compressing distance (displacement). This is because the compressing force becomes bigger if you continue to press the ball, thus, you need to compare the compressing force at a certain displacement. It is used for R&D and quality control.　

This is compression test for measuring the hardness of tablets (pharmaceutical tablets). In this video, a tablet is pushed until it breaks using IMADA force gauge and a flat attachment. This test determines the hardness of tablets by obtaining the maximum load value when fracture initiates. Watch the video for more details. Tablet hardness testing is used for R&D and quality control.

Cosmetic foundation is pressed to measure its hardness for quality control and R&D.

This is plastic bottle top-load testing for characteristic evaluation, and quality control.

This is shoe sole hardness test for comfort evaluation, quality control and R&D.

Operating force of a switch is measured with a manual test stand in this video. This type of measurement is also called switch feeling test and describes easiness of pressing switches or click feeling in numerical values. By setting Peak Drops(decreasing values) on the force gauge, the force at the moment when the switch gets on is recorded as the first peak value. Displacement value to turn the switch on can be measured using the test stand with displacement input function.

Force to operate motorcycle’s brake lever is measured by a dedicated load cell and amplifier. You just mount the load cell on a brake lever, grip them together, then the operating force is indicated. The tested data can be stored in the internal memory of the force gauge. You can also check the stored data directly on the force gauge's display easily. This test is used for inspection, safety evaluation and quality control.

IMADA's force-displacement tester determines click sensation (feeling) of tactile switches. In the video, the tester presses a switch, measuring the resistance force and graphing the measurement. In other words, to determine the click sensation, you need to measure displacement as well as force. Then, the tester graphs force transition with reference to displacement, helping identify the hysteresis (zero reversion). Thus, the force-displacement tester handles various characteristic evaluation other than click sensation of switches. The remarkable thing is that the tester automatically detects contact point of the sample and presses switches by pre-set displacement, which improves repeatability and test-efficiency.

Force to step foot brakes is measured by a dedicated load cell and amplifier. You just mount the load cell on a foot brake, step them together, then the stepping force is indicated. This test can also be applied to accelerator pedal. This test is used for inspection, safety evaluation and quality control.
