  Zipper, according to size: # 3, # 4, # 5, # 7, # 8, the zipper size microphone teeth the size change.Because of its often used in jeans, jacket and backpack, so the size of its zipper; types are divided into zipper opening zipper (detachable), dual tail zipper closure (X-zipper with double slider two relatively or O-zipper with double slider two contrary), double open end zipper (inverse open spin-offs).
  In our daily clothing cleaning or processing when it is necessary to pay special attention to the wool knitwear after ironing zipper fully cooled before packaging to ensure that, otherwise, the metal zipper will react with water vapor, easy to change color; in the clothing merchandise processing, it is easy to residues of certain chemical agents, it is easy to react and metal zipper.The so before assembly metal zipper, the need to ensure that the leather has been fully cleaned and in and.
  Many a tensile machine tensile testing machine for zipper, not so special, of course, such as customer special requirements, we will make the greatest efforts to satisfy.Positive Bang Rak force tester control software can achieve automatic strike tensile strength, yield strength, breaking strength, elastic modulus, elongation, and other detection data, open Equation Editor can automatically calculate any one of the specified point in the testing process force, stress, displacement and deformation data results.The test process control and data processing complies with the requirements of the national standards of the corresponding metal materials and non-metallic materials.
  The Masakuni zipper tensile testing machine can set the pace, position shift, constant load, constant load growth rate, given stress, given the stress growth rate constant strain, constant strain growth rate, after the start of the test, the measurement system automatically zero; according to load size automatically switch to the appropriate range to ensure the accuracy of the measurement data; auto-save: automatically save test data and test conditions, eliminate data loss due to forget to save; specimens of the same parameters, a set sequentially complete a number of tests.
  Of course, positive the Bang Rak force test machine data with the curve of the test results with the test process dynamic display after the test is completed, the re-analysis of the curve to identify the data corresponding to the points on the test curve with the mouse; selectable stress - strain, force - displacement force - time, displacement - time curve display and print; forces units: (g, kg, N, lb), stress: (kg/mm2, N/mm2, Mpa, lbf/in2) Displacement Unit: ( m, mm, in), the same time according to the format required by the user for programming and printing of the test report, and can export the EXCEL file; achieve security protection more than 2 to 10% of the maximum load, automatically; can be automatically detected, the sample is calculated mechanical performance, can also be artificial intervention in the analysis process to be corrected in accordance with the requirements of the relevant standards for automatic analysis, in order to improve the accuracy of the data.
  Add that the shape of the metal zipper pull head more finished both small and delicate, and also can be rugged and majestic.But regardless of what the slider must be to feel comfortable whether, slider pull Kai zipper pull on the Bulong the phenomenon will occur.Slider now available on the market with a self-locking device, in zippered, was to test the zipper slid down the lock fixed.
