I. progress of new products

1. New products to fill the domestic gap

① full sheet monochrome, two-color and four-color series of sheet fed lithography printing machines have been successfully developed by Beiren Printing Machinery Co., Ltd. and jiangsuchang Yi Machinery Co., Ltd. Henan Xinji Co., Ltd. also launched a full sheet two-color sheet fed lithography press. The maximum size of the sheet fed printer is expanded to '1020mmx1440mm and 1020mmxl420mm, and the printing speed is also 5000-7000 sheets/hour respectively, so as to meet the needs of packaging and printing

② for a long time, China has imported two kinds of products duty-free, namely, sheet fed offset multicolor lithographic printing machines and web newspaper printing machines. The main technical indicators of duty-free import are sheet fed lithographic printing machines with a speed of more than 15000 ·/h and web newspaper printing machines with a speed of more than 60000 ·/h. Through the efforts of the enterprise, beiren's beiren 300 folio multi-color lithography press has reached 15000 sheets/hour. The equipment not only passed the identification, but also began mass production. Shanghai Gauss printing equipment Co., Ltd. also produces 15000 pieces/hour of duty-free import line

the medium-sized Web newspaper printing machine produced by Shanghai Gauss printing equipment Co., Ltd. and Beiren Printing Machinery Co., Ltd. has reached the maximum printing speed of 70000 sheets/hour and 75000 sheets/hour respectively, exceeding the duty-free import line respectively. The above equipment has been exhibited at CHINApRINT2005 exhibition and has achieved good exhibition results

due to the introduction of domestic equipment (of course, it is also related to the market decline this year), the import of these two kinds of equipment began to decline. From January to May 2005, 385 sheet fed printing machines were imported, with an import volume of nearly 241million US dollars; 31 web printing machines were imported, with an import volume of 3744 million US dollars. In 2004, 1052 sheet fed printing machines were imported, with an import value of 631million US dollars; 106 web printing machines were imported, with an import volume of 169million US dollars. Compared with that, it is expected that the import volume this year will drop significantly. On the contrary, the export of these two printing machines has achieved good results over the years. According to the export statistics from January to May 2005, 215 sheet fed printing machines were exported, with an export value of 51... 26300 US dollars, which is close to the export value of 6.337 million US dollars in 2004. 52 web printing machines were exported, with an export volume of US $10.1447 million, which is close to half of the annual export volume in 2004. From the export situation of these two products, increasing exports and opening up foreign markets are one of the driving forces for the development of the printing machinery market

③ semi commercial and commercial web offset printing machines have grown from scratch, and the products have entered commercial operation in the printing plant, and the printing speed has increased from 35000 sheets/hour to 40000 sheets/hour. These printing machines are equipped with zero speed automatic paper feeder, secondary tension control, automatic registration device, drying system, cooling unit, silicon adding device and other connecting equipment, which can fully adapt to the commercial printing of coated paper

④ in the past, 520mm small offset multicolor printing machine was one of the varieties that all depended on imports. Since 2000, Weifang Huaguang precision equipment Co., Ltd., Weihai Printing Machinery Co., Ltd., Yingkou Guanhua offset printing machine Co., Ltd. and Beijing Duoyuan electric group have launched this series of products respectively. Among them, Weifang Huaguang has carried out mass production and assembly line assembly, and has reached a certain production scale since 2004. According to the figures published by the enterprise, so far, It has successively sold 76 multi-color small lithographic presses to the printing market, and achieved the excellent result of exporting 8 sets. From January to May 2005, the export volume of sheet fed printing machines increased rapidly, mainly due to the contribution of small offset printing machine manufacturers

⑤ books and periodicals online binding equipment has made rapid progress. During the Tenth Five Year Plan period, the automation level of post press binding equipment increased rapidly, and it has developed from a single sequence semi-automatic equipment for book binding to an on-line automatic equipment, breaking the pattern of being produced by Shanghai Ziguang alone for many years, and began to expand to beiren group company, Shenzhen Jingda machinery Co., Ltd., Henan Taifeng Printing Machinery Co., Ltd., Huainan Guanghua binding machinery factory. Horse riding binding linkage line, wireless Automatic equipment such as binding linkage line, automatic shell pasting machine, stacking and bundling machine, book seal folding front mouth machine, etc. have been mass produced. Another group of enterprises began to produce semi-automatic and automatic cartons, shell making and other series of equipment for the packaging and printing industry and book binding industry

⑥ flexographic printing machines have been produced by more than ten enterprises, and the main varieties and specifications are constantly expanding, including narrow width unit flexographic printing machines manufactured by Shanghai Ziguang Machinery Co., Ltd., beiren Fuji Printing Machinery Co., Ltd., Shaanxi Heiniu Machinery Co., Ltd., laminated flexographic printing machines produced by enterprises such as Wenzhou Donghai, and sheet fed flexographic printing machines produced by Shaanxi Xianyang Hefeng, The flexible self-adhesive printing machine (satellite type) and other varieties produced by Shanghai Sun have also expanded from 420mm to 460mm, 480mm and other larger specifications. The mass production of flexographic printing machine, on the one hand, blocks the influx of foreign equipment, on the other hand, provides an efficient and environmental protection process method for the packaging and printing industry, and gradually replaces the original web gravure printing machine printing, slitting machine slitting, die-cutting machine forming process in the field of mass production of packaging cartons

⑦ in order to meet the needs of large-scale gold, silver and field printing of cigarette, wine and other packaging cartons, sheet fed gravure printing machine products have developed rapidly during the "Tenth Five Year Plan". Beijing zhenhenri Printing Machinery Co., Ltd. has mass produced monochrome, two-color and four-color sheet fed gravure printing machines, Shanghai Ziming Machinery Co., Ltd. can also produce monochrome and two-color sheet fed gravure printing machines, and a number of sheet fed gravure printing machines developed by enterprises have formed a scale and replaced imports

⑧ from the end of the 20th century, the digital wave swept the printing equipment manufacturing industry. After nearly a decade of development, digital printing machines, digital plate making machines, digital proofing machines and other equipment have rapidly developed into new markets, showing a rapid growth trend. China's printing machinery manufacturing enterprises have also made some progress during the Tenth Five Year Plan period. Among them, beiren group and saiangel have launched large format inkjet printing machines in cooperation, Yingkou Guanhua offset printing machine Co., Ltd., Hangzhou Kelei, Beijing Duoyuan electric group and other enterprises have begun to mass produce digital plate making equipment, and the digital direct plate making equipment produced by Yingkou Guanhua has achieved mass export
