General testing method for tensile strength and elongation of footwear outsole. Tensile strength: the tensile stress at the maximum force value. Elongation at break: The ratio of the length increased by the test length to the original length when the sample is broken. Stress at specified elongation: The stress required when the sample reaches the specified elongation. Test equipment and auxiliary devices: 1. Tensile testing Machine for footwear 2. Die and cutter: Die for dumbbell-shaped specimens. The parallelism of the narrow part of the die should not exceed 0.05mm. 3. The thickness gauge has a stable platform, and its presser foot has a fixed weight load, which can apply a pressure of 10kPa ± 3 kPa. The diameter of the circular flat presser foot of the thickness gauge is 10.0mm soil 0.1mm. 4. The scale of the thickness gauge scale is 0.01mm Universal Material Tensile Testing Machine: 1. The moving speed is constant at 100mmmin, the accuracy is level 2, and the force value can be automatically recorded. Sample preparation: 2. The sample thickness is: ———High-density outsole made of polymer and elastic materials, with a thickness of 2.0mm 土0.2mm  ———Foamed microporous outsole, with a thickness of 4.0mm 土0.2mm. ———Leather outsole: thickness is outer sole thickness. 3. The number of samples for each test is at least 3, and a suitable layering machine should be used to obtain a uniform thickness. If feasible, the original smooth "skin" of the sample should be retained. Electronic universal testing machine Test Method: Mark the sample: If a non-contact star detector is used, use a suitable scribe to draw two reference marks on the sample to determine the test length of the sample, and mark two on the narrow part of the sample The reference mark that is equidistant from the center of the sample and perpendicular to the axis of the sample, as shown in Figure 2. When marking, the sample should be in an untensioned state.

What is the Carton Compression Tester This computer control Carton Compression Tester uses high-precision force sensor to test the resistance value of pressure and display it directly. The most direct equipment for testing the pressure resistance of containers made of cardboard or other materials. It is used to determine the cargo capacity and stacking height of the carton. It is suitable for the compression and holding test of various packages and cartons. The test results can be used as an important reference for the stacking height of the finished packaging box or an important basis for packaging box designing. How to maintain the box compression testing machine The Box Compression Tester will rust, precision error and other problems after a long time of use, which belong to the reason for not doing a good job of maintenance of the instrument. Therefore, GESTER sort out some of the carton compression testing machine maintenance methods for your reference. Maintenance : 1. LCD Model Box Compression Strength Tester must use the specified power supply and correct grounding. 2. Use the fuse within the specified limit. 3. failure, the operator to check and eliminate, can not run with disease. 4. Lubricate all moving parts from time to time. 5. if the printing paper roll is used up or the handwriting is not clear, replace the printing paper roll or ribbon. 6. Properly add oil to the transmission chain. The oil should not be too much. 7. The two drive screw to maintain proper lubrication, lubricating oil with specified mechanical oil, refueling must be removed from the two columns at the opening of the dust cover. 8. The working environment is kept clean and hygienic. 9. In order to keep the machine in good technical condition, periodic verification is carried out. GESTER Since our foundation, we have been concentrated on the research and development of physical testing instruments. As a result, our products are compliant with ISO, ASTM, DIN, EN, BS, GB, JIS, ANSI, UL, TAPPI, AATCC, IEC, VDE, CSA as well as other standards, and they are preferred by both domestic and overseas customers due to their high accuracy, excellent.

Users in the use of universal material testing machine, sometimes there will be some failures.  If the user can deal with the failure in time, it can improve the work efficiency of the enterprise, which is especially important when the project is on schedule. So Gester provides users with some common troubleshooting methods, hoping to help everyone. Solution to the failure of material tensile testing machine: 1. The power supply has electricity but the tensile testing machine can not move up and down. Check whether the power supply voltage of the access material tension tester is normal, check whether the upper and lower limit is in the appropriate position, etc. 2. After the tensile testing machine is online, a prompt box appears indicating overload. Check whether the on-line selection sensor is selected correctly, whether the sensor has been hit by accident, whether the communication line of the tensile testing machine has fallen off, check whether the calibration value has been manually changed, etc. 3. Plug it in and use it for a while, and suddenly there is no reaction. Check whether there is any problem with the wiring, whether the socket is plugged in, or the cable is almost cut off by a mouse, and check whether the power supply voltage connected to the tensile tester is normal.
