A box-making machine, also known as a carton former, opens the folded corrugated fiberboard to make a box. The machine may shut down due to the variation of force to bend the score and the crease on the folded corrugated fiberboard. Thus, the management and testing of bending force of corrugated fiberboard is necessary. This video shows how to measure the maximum force when bending the corrugated fiberboard complying with JCS T0001: 2000, by using IMADA customized attachment and testing equipment. Moreover, By using the graphing software, the transition of the force to bend the corrugated fiberboard can be checked visually.

Parts like two sheets (plates) bonded with an adhesive are common in kinds of products in various industries. In any manufacturing industry, it is vital to make sure that the bonding strength is sufficient, as there is a potential risk of damage to the product or injury to the user if the two sheets are easily peeled off due to the weak bonding strength. There are various test methods such as shearing, peeling and bending to measure the bonding strength. This video introduces shearing test, which means that both ends of the two sheets are gripped and pulled until they are separated. The sample in the video is a bonded plastic sheet, so a flat chuck with rubber bonded claws (optional) is used to prevent the sample surface from scratches or damages during test. The optional graphing software shows the entire force transition until the bonded part separates, which helps you analyze the bonding strength. Shear bond strength tests are widely applied for kinds of samples in various industries for quality evaluation and quality control.

This is pullout test of a crimped connector of wire harness complying with the corresponding part of UL 486A-486B: Edition 3. In this test, our auto crimp tester keeps pulling crimped connector of wire harness for 60 sec with steady force at a constant pace to check if the connector breaks or not. If you change jigs to hold connectors, you can conduct this test for various shapes of wire connectors. This test is carried out by using "Keep mode" of our auto crimp tester which allows users to conduct durability tests easily. Also you can implement measurements complying with other standards. Please see "Related Applications" videos below.

Slide fasteners (zipper) are widely used for clothes such as jackets, trousers, and skirts, and play an important role in closing them. It is necessary to check the strength of each part of the slide fasteners for quality control and usability evaluation. The test methods are described in JIS S 3015: 2019. This video measures the strength of a fastener when its lateral box (bottom stop) is pulled to break using a method that conforms to JIS S 3015-7.6: 2019. With the optional graphing software, it is possible to visually analyze the transition of force until the opening is removed. IMADA also offer solutions for other tests that comform JIS S 3015: 2019.

Force measurement is widely used for safety and quality control in clothes manufacturing. Cloth button pull-off strength test is one of the typical application.
What if a button comes off from a customer's relatively new shirt? The customer would be disappointed, and maybe have bad image to the clothes and the brand. Moreover, it is extremely dangeous if a child accidentally swallowed the come-off button. Therefore, it is very important to manage the sewing strength of the cloth button. This video shows the cloth button pull-off strength test with manual test stand. Manual type features low-cost and easy-to-use compared to motorized type, thus it is adopted in many factories. For more precise and repeatable measurement, the motorized test stand is recommended.

This is pull test on crimped terminal of high-voltage wire harness complying with the corresponding part of JIS C2805:2010. The crimped terminal is continuously pulled at a certain force based on the sample size for 10 seconds. After the test, check if the connector part was NOT pulled apart. It is used for R&D and quality control.

There are 2 ways to measure the tension strength of crimped terminals, durability test and break test. The break test complying with the coresponding part of IEC 60512-16-4: 2008 requires you to determine the maximum force value when the terminal is pulled off. On the other hand, the durability test complying with the coresponding part of JIS C2805: 2010 requires you to pull the crimped terminal continuously at a certain force for 10 seconds, and check the connector part situation after the test. They are used for R&D and quality control.

Sealing strength of corrugated cardboard is measured by IMADA's force gauge and a dedicated hook. You just insert the hook into the gap and pull it up until the cardboard is unsealed, the force gauge captures the maximum force value, which is the cardboard's sealing strength. It is used for quality control.

Aluminum foil is used in a wide range of industries such as food, pharmaceutical, chemicals, electrical equipment and industry. In this video, the breaking strength (easiness of tearing) of aluminum foil for food is measured. Both ends of the aluminum foil are gripped and pulled until it breaks, then the peak force represents the breaking strength. To grip the thin and fragile aluminum foil firmly without tear, a flat chuck with parallel claws (optional) is used . In addition, the optional graphing software shows the entire force transition until the aluminum foil breaks, which helps you analyze the breaking strength. The breaking strength of aluminum foil for other industries can also be tested.
