This is 3-Point bending test of round bar shaped sample which used as material for construction and furniture manufacturing. It is for material safety evaluation and quality control.

This is spot welding bonding strength test for safety evaluation and quality control.

Safety of automatic sliding doors always need to be secured. In this test, dynamic and static forces of automatic sliding doors are measured to ensure their safety. This test requires an optional extension shaft whose length fits the distance between the wall and door, indicated by the standard, to comply with the corresponding part of JIS A4722:2017. When the sliding door hits the loadcell, the peak impact force value is measured and the software to draw a Force-Time graph allows the tester to confirm whether dynamic and static forces are withing the limits. Another optional item, our extension shaft handle, is recommendable to increase the accuracy of the test. This measurement unit is suitable for daily inspection of automatic sliding doors.

This is key turning force (torque) test. Using rotation support jig, the torque transition during one turn of the key is analyzed for evaluation and quality control.

This test is to measure closing force of a fire shutter for inspection.

This test is performed to measure closing force of a fire door according to the Building Standard Law of Japan for inspection.

This video is about measurement friction force of a pen, one factor of writing comfort, by using our variable weight reciprocating friction test jig. You can also generate vertical force like writing pressure by placing weight you prepared on the plate. The test result is easily graphed or calculated into coefficient of dynamic friction by supplied software. You can also overlay the graphs and compare test results of different types of pens.

Earthquake-proof mat is used to adhere the furniture on a floor to avoid its falling down during the earthquake. The adhesive force is important to the quality of earthquake-proof. This video shows how to measure the adhesive strength of the earthquake-proof mat by tack test. Tack test is performed like this: Compress the mat at a certain speed until it reaches at a certain force then return, then the force gauge indicates a maximum force of the return,　which is the earthquake-proof mat's adhesive strength. It is used for R&D and quality control.

This is clip retension test against paper. To measure the retension force, combine an IMADA's force gauge and a film chuck, grip the paper by the chuck and a clip, and pull the paper away from the clip by hand. Then, the force gauge indicates the maximum force, which is the clip's retension force. This test is used for R&D and quality control, and able to apply for different samples such as film.

Helmet shield is pressed up (opened) to test its operability. It is widely used in operability evaluation tests.

Grip/pinch the clip to the specialized attachment to measure gripping/pinch force for performance evaluation, quality control and R&D.
