How are zipper brakes used in many fields made?

First, the master polished the metal on the galvanized disc, and then he cut and positioned it on the metal. Then he applied adhesive to the polished place. Then, the master used a steel needle as a guide and put a magnet on the glue. This is a factory specializing in the production of slider brakes. Next, the master put a bearing in the center of the disc and punched it into the hole with a hydraulic press. The braking force of the brake comes from the rotation of these rotor walls in the magnetic field. The master installed the gear on the rotor wall and fixed it firmly with bolts. Then he put the rotor into the brake drum to test whether it can rotate freely.

Second, the next step, the master put a circle of magnets around the rotor. Then there is a ring with more gears. He knocked with a hammer and then bolted the neck. When the master rotates the assembly again to confirm that it can rotate freely, he installs the last two parts above the rotor, and the core parts of the brake are assembled. Next, another master sewed nylon on the synthetic belt. It will be used to start the brake, make the rotor B rotate and generate eddy current released into the power.

Third, then, the master put the equipment into a plastic box and installed a steel plate on the spindle. Then, he wound the ribbon around the equipment and put it in a round metal box. So, master. Put the contraction spring in a metal box and cover it with a metal cover. Then he turned the handle to let more woven bags roll into the equipment. Next, the master inserted the guide rail into the woven bag and fitted two plastic clips, and the circular metal was used to fix the clips. Then, the master installed a plastic plug-in on the brake top and fastened it with bolts. Finally, the whole device is covered by a plastic shell. So there is a stop-and-go slider brake. No matter how fast you land, you will land slowly.
