After decades of development of generator muffler, the color printing and packaging industry in Ehu town has formed an industrial belt. As the "hometown of color printing", there are still low-grade products, backward packaging design, narrow packaging surface, and most of the liquor packaging is of medium and low-grade. Because of the small flow of local talents, there is an urgent need for professional talents in graphic design and printing technology, as well as the technical support of colleges and universities. Only in this way can the local printing equipment, technology, design and process realize the transformation of "pre press digitization, networking, multi-color and high efficiency, post printing diversification, automation and high-quality serialization". The proposed project is injection molding automation and spraying automation; the technical problems to be solved are that the injection molding production is changed from manual operation to robot operation, and the spraying on the upper cover of Siemens washing machine is changed from semi-automatic to full-automatic; the main technical index is that the injection molding automation is determined by the specific design (the installation of injection molding machines with different mufflers is quite different), so as to realize automation as much as possible Standard. In order to meet the needs of power industry technology development, Wuxi Huatong Power Equipment Co., Ltd. plans to introduce and develop htgl-25 automatic quantitative feeder.
