Jinming helps the localization process of large and wide vacuum casting film

Recently, another five-layer co-extrusion vacuum casting film unit of Jinming Seiki successfully passed the start-up test. This unit has achieved a major breakthrough from a width of 12 meters to a width of 16 meters, and the maximum output has also increased from 1.3t/h to 2t /h, which marks a leapfrog breakthrough in product specifications and unit production capacity of domestically produced large and wide vacuum casting films.

The equipment adopts international advanced technology and involves multiple patented technologies independently innovated by Jinming Seiki. It can produce high-quality films and is mainly used in the production of wide-width multi-layer films for wind power and aviation.

【Vacuum casting film】

Wide-width multi-layer film for wind power and aviation, that is, vacuum casting film, can form a vacuum system, provide good coverage and sealing, and is the outermost coating material of the vacuum packaging system. Vacuum casting film has the characteristics of high strength and high elongation, and can directly contact resin. It is mainly used for high-temperature forming, vacuum injection and pre-compaction of composite materials. It is currently widely used in wind energy, shipbuilding and aviation industries.

[R&D Background]

In recent years, China's manufacturing industry is gradually moving from low-end to high-end industries. The manufacturing industry chain is deepening and the coverage of manufacturing industries is expanding. Energy conservation and environmental protection, cost reduction and efficiency increase have become important indicators for enterprise development.

In terms of the processing of new materials served by the plastic machine industry, lightweight composite materials such as carbon fiber, polyester, vinyl ester and epoxy resin are developing rapidly, and clean energy such as wind energy and solar energy is growing rapidly, which also drives 6-12 meters The demand for wide-width PA composite films for wind power and aviation shows double-digit growth.

In the first half of 2020, my country's wind power industry completed an investment of 85.4 billion yuan, a year-on-year increase of 152.2%. The market demand for wide-width films is increasing.

Due to the small number of vacuum casting film production equipment in my country, the narrow width, and low production capacity of a single machine, it is urgent to carry out industrial upgrading and technological innovation to meet the needs of social development.

In 2012, Jinming Seiki produced the wide-width multilayer film through the self-developed M5B-3200-C five-layer co-extrusion vacuum casting film equipment, which broke the situation that China relied on imports of high-temperature resistant films for precision casting in the early years. The developed equipment can only produce films with a width of less than 6 meters, and the wide multilayer films with a width of 6 to 12 meters still rely on imports. Most of the wide multilayer films with a width of 12 meters used in China are made of Produced by leading companies in the European and American industries, the price of wide-format films remains high.

The Jinming Seiki team successfully developed the M5B-12000-C equipment in 2017 through technological breakthroughs. This equipment has obtained a number of invention patents and successfully solved the problem of relying on imports for 12-meter-wide multilayer films.

Recently, the M5B-16000-C five-layer co-extrusion vacuum casting film unit of Jinming Seiki passed the start-up test. It adopts a high compression ratio screw design and deepens the screw depth of the screw feeding section to ensure that the screw delivery capacity meets the design output requirements; Through the structural design, the risk of material leakage between the die heads is reduced. On the premise of ensuring the output and the melt shear rate, the pressure of the die head is reduced, the quality of the melt is improved and the energy consumption is reduced. Successfully through multi-functional production, cracking The problem of short production cycle of wide-width production equipment.

Jinming Precision Machinery will continue to focus on scientific research and innovation, constantly break through technological shackles, and help the development of the plastic machinery industry.
