In recent years, China's plastic machinery industry has developed rapidly, and the domestic 7 layer co extrusion machine has made remarkable progress in technology and production capacity. As a high-end equipment widely used in food packaging, medical protection, agricultural covering and other fields, the 7 layer co extrusion machine has obvious cost advantages compared with similar foreign products, and its product performance is gradually approaching the international advanced level. However, to break through the technical and market barriers of foreign markets and gain a firm foothold in the global competition, domestic 7 layer co extrusion machine manufacturers must establish and improve information technology, which has become an indispensable key link in their internationalization process.

The 7 layer co extrusion machine is a complex high-tech equipment that integrates multiple technologies such as machinery, electronics and materials. It can extrude seven layers of different materials at the same time to form composite products with multi-functional characteristics, which are widely used in high-end packaging and industrial fields. In the domestic market, with the support of policies such as Made in China 2025 and the promotion of downstream industry demand, the production scale of domestic 7 layer co extrusion machine has been expanding, and some leading enterprises such as Jinming Precision Machinery and Huari Plastic Machinery have even achieved breakthroughs in core technologies such as seven-layer co extrusion die heads and intelligent control systems. However, when entering foreign markets, domestic manufacturers are often limited by the backwardness of information technology, resulting in difficulties in meeting the personalized needs of foreign customers, slow after-sales response and lack of competitiveness in international certification, which restricts the further expansion of the export market.

Establishing information technology can help domestic 7 layer co extrusion machine manufacturers break through the technical barriers of foreign markets. Foreign markets, especially European and American markets, have strict requirements on the precision, stability and intelligence of equipment. For example, Italian Colines' 7 layer co extrusion production line is equipped with an AI control system, which can realize automatic die mapping, automatic reel size change and real-time production monitoring through big data analysis, greatly improving production efficiency and product quality. In contrast, some domestic 7 layer co extrusion machines still use traditional manual operation and simple control systems, which cannot meet the high-precision and intelligent requirements of foreign customers. By establishing information technology, integrating Internet of Things, artificial intelligence and digital twin technologies, domestic manufacturers can realize real-time monitoring and automatic adjustment of equipment parameters, improve the precision and stability of the 7 layer co extrusion machine, and make the product performance meet the international standards, thus breaking through the technical barriers set by foreign markets.

Information technology is also an important guarantee for domestic 7 layer co extrusion machine to meet the personalized needs of foreign customers. Different countries and regions have different market demands for 7 layer co extrusion machine due to differences in downstream industries, technical standards and usage habits. For example, the European market pays more attention to the environmental protection and energy-saving performance of equipment, requiring the 7 layer co extrusion machine to use recyclable materials and reduce energy consumption; the North American market focuses on the efficiency and safety of equipment, and has high requirements for the production speed and fault self-diagnosis function of the equipment. Without a sound information system, domestic manufacturers are difficult to quickly collect and analyze the demand information of foreign markets, and it is even harder to customize the 7 layer co extrusion machine according to the specific needs of customers. By establishing a global information collection and analysis system, manufacturers can timely grasp the market demand dynamics of various countries, customize personalized equipment solutions, and improve customer satisfaction and market competitiveness.

In addition, information technology can effectively improve the after-sales service level of domestic 7 layer co extrusion machine in foreign markets, which is a key factor in winning the trust of foreign customers. The 7 layer co extrusion machine is a large-scale equipment with high technical content, and its after-sales service involves equipment installation, commissioning, maintenance and technical training. Foreign customers have high requirements for the timeliness and professionalism of after-sales service. At present, some domestic manufacturers have weak after-sales service capabilities in foreign markets, with slow response speed and insufficient professional technical personnel, which affects the market reputation of domestic 7 layer co extrusion machine. By establishing an information-based after-sales service system, using remote monitoring technology to realize real-time fault diagnosis of equipment, and setting up an online technical support platform, manufacturers can quickly respond to customer needs, solve equipment failures in a timely manner, and provide professional technical training, thus improving the after-sales service level and enhancing customer trust.

It should be noted that establishing information technology for domestic 7 layer co extrusion machine to enter foreign markets is not only about upgrading equipment technology, but also about building a complete information management system covering R&D, production, sales and after-sales. Manufacturers need to increase investment in information technology, introduce advanced information management tools, train professional information technology talents, and realize the integration of information technology and production and operation. At the same time, they should actively learn from the experience of foreign advanced enterprises, strengthen international cooperation and exchanges, and continuously improve the informationization level of the 7 layer co extrusion machine, so as to better adapt to the needs of foreign markets.

In conclusion, the domestic 7 layer co extrusion machine has great potential in the foreign market, but the establishment of information technology is an inevitable requirement for it to enter and expand the foreign market. Only by integrating information technology into all links of equipment R&D, production, sales and after-sales, improving product performance, meeting personalized customer needs and enhancing after-sales service level, can domestic 7 layer co extrusion machine break through international market barriers, gain a firm foothold in global competition, and promote the high-quality development of China's plastic machinery export industry.
