Actually, a wiper assembly that refuses to move might have a simple blown fuse. But usually fuses don't blow on their own. Even at full stall, the current draw of the motor should be well below the fuse's rating. If the fuse is blown, odds are there's something else wrong, like a shorted wiper-motor armature or faulty wiring anywhere along the harness between the motor and the switch. Even a mechanical problem like a seized bushing can make a fuse eventually fail.
The fuse is okay, or you've replaced it with one that has the appropriate amp rating. There's still no action? With the wipers and ignition on, whack the motor assembly with the handle of a screwdriver or a rubber mallet. If that gets things moving, you've got a bad commutator or an open winding on the armature. When the motor parks, if the brushes are sitting on the bad segment, no current flows. Whacking the whole business smartly can sometimes jolt things into motion. Because there are often a dozen windings on the armature, the motor runs fine until the next time it comes to rest on the bad spot.

Perhaps 10 years of arguments are too conservative, because China is undergoing an accelerated development process. As a free and open market, the international door has been open to Chinese packaging companies. The question is only when and how Chinese packaging companies enter and succeed.
Open China continues to create miracles that make the world wonder.
Whether Chinese particle packaging machines can open up the international market is related to the technological level of Chinese particle packaging machines on the one hand, and the shape of the international particle packaging machine market on the other.
Through imitation, the introduction of technology and capital, and global procurement, the level of manufacturing and the level of industrial design of particle packaging machines in China have been rapidly developed. Today, China's particle packaging machine manufacturers can easily acquire some key components through global procurement, thus rapidly improving the technical level and reliability of the equipment. If machines made in China cannot compete with German, Italian and Japanese products on high-speed fillers, labelers, case packers, robots and other equipment, then in some products with lower technological content, China’s current production Many of the pellet packaging machines have already met the requirements of the international market and are likely to make breakthroughs in the short term. In particular, some general-purpose particle packaging machines, such as heat shrink packaging machines, sealing machines, filling machines, labeling machines, sealing machines, vacuum packaging machines, weighing/filling/granule packaging machines, etc. Less than half of international products, with strong competitiveness. The low price is a good step for China's pellet packaging machines entering the international market.
As a highly-developed liberalization market, the phenomenon of “polarization†of international particle packaging machine makers is evident. The small and exquisite electronic products represented by test preparation and coding devices are flourishing in the international market, and general-purpose particle packaging machines based on heat-shrinking packaging machines, sealing machines and sealing machines also occupy a considerable proportion; Large-scale particle packaging machine production lines, including machine, labeling machine and capping machine, have basically no production in the international market. The market is almost entirely occupied by imported equipment, especially equipment manufactured by German and Italian manufacturers.

China's particle packaging machines compete for the international market
30 years ago, who would believe that Chinese-made granulator packaging products can occupy an important position in the international market, and even determine the global price of the particle packaging machine market? Today, who would doubt that in 10 years, the international packaging market will use a large number of particle packaging machines made in China?
