Slider Assembly: Slider Assembly (拉头组装)
The step in which the slider body, bridge or pawl, spring and puller are put together and adjusted. Correct spring tension, pawl height and puller freedom determine locking reliability and pull feel. Automated assembly lines feed parts, rivet or crimp the puller and test function. Faulty assembly causes self-opening, a stiff puller or a detached tab. Finished sliders are sampled for locking force, pull-off force and smooth travel.
