Magnetic card, magnetic recording medium card, made of high strength, high temperature resistant plastic or paper coated plastic, that can be moisture-proof, wear-resistant, and have certain flexibility, which is convenient to carry, use, more stable and reliable. So they are widely used in all aspects of daily life: banking, securities, transportation, food… Increasing needs for magnetic cards on people’s life force the international magnetic card manufacturers to develop more and more strict process standards. In addition, in addition to following the basic production standards, improving the comfort and convenience of magnetic card use have also become the focus of many production enterprises to highlight the encirclement, to win the favor of consumers. Labthink, according to ISO 7810 of magnetic card and combined with years of research and production experience of testing instruments, has launched some testing programs for magnetic card quality testing technology.

1, magnetic card thickness detection

According to ISO 7810, the international standard of magnetic card on the physical performance of the magnetic card, the thickness of the magnetic card should be 0.76±0.08mm. Therefore, the thickness detection of magnetic card is to detect and control the thickness of magnetic card. On the other hand, it can save the raw material input and increase the output value. Take Labthink C640 Thickness Tester as an example, the thickness tester adopts the principle of mechanical surface contact type measurement, and the resolution is up to 0.1 micron. In addition, the operation of the instrument is very simple. Due to the automatic feeding function, it only needs to set the measurement points, sample step distance/interval, test time and other parameters before the test, and click the Test to start the test. Labthink is continuous innovating, researching and developing while accumulating technologies, the tester uses ultra-high precision displacement sensor, scientific structure layout and professional control technology to achieve high test stability, repeatability and precision.

2, magnetic card film stripping testing

In the use of magnetic card, the magnetic card will be subject to the action of many external factors leading to the separation of the surface coating from the substrate. Although it does not affect the use of magnetic card, it will destroy the touch of consumers, reduce the use of feelings. In order to extend the close binding state of the film and the substrate and delay the separation time, in the production process, it is necessary to test magnetic card sample, including testing the stripping strength of the film and the substrate in advance, that is, the film will be separated from the substrate under much force, so as to improve the filming process. Labthink BLD-200N Stripping Tester have for models with different load ranges according to the customer’s detection requirements, i.e., 30N/50N/100N/200N, with an accuracy of level 1 and a minimum detectable tension of 0.06N. The instrument is controlled by a microcomputer, and has two major functions of stripping and stretching. The specific detection method is very simple: first of all, sample the magnetic card according to the requirements and peel off part of the film and substrate, and keep both firmly fixed on the fixture. Secondly, set the test parameters according to the standards or the experimental requirements. Finally, click on the start button to start the test. The whole test process will be completed automatically by the system control, and the test results are printed by the built-in microprinter.

The above several magnetic card detection items, in the actual production, are vital to adjust the production process and improve the product quality. Through the corresponding test instruments, to control and master a reasonable variety of technical parameters, the materials can be well used in the production of magnetic cards while control quality and control costs. Labthink is committed to helping customers deal with packaging problems through the improvement of packaging testing technology and the research and development of testing instruments, and helping the quality and safety of packaging related industries.
