The proportional valve is simple in structure, light in size, easy to install and disassemble, and is a direct-acting hydraulic control valve between ordinary hydraulic valves and electric hydraulic servo valves. It can make its output proportional to the control input, realize remote control of hydraulic parameters, and can also be used as a signal conversion and amplification component in a closed-loop control system.

1, product varieties and complete sets of small quantities. Most of the domestic production of single-machine, while most of the foreign production support, and rarely stand-alone sales. On the one hand, the variety of domestic equipment can not meet the needs of domestic food and packaging companies, on the other hand, machinery factory profit on the stand-alone production and sales meager, can not obtain the high efficiency of complete sets of equipment sales.
2, the level of technology is low. The main performance is poor product reliability, slow technology update, and less application of new technologies, new processes, and new materials. China's food and packaging machinery have more stand-alone machines, complete sets, fewer general-purpose models, special requirements, and less special equipment. There are many products with low technological content, and there are few products with high technology added value and high productivity. Intelligent equipment is also in the dry development stage. And foreign countries have applied many advanced technologies to packaging machinery, such as remote-distance remote control technology (including monitoring), stepper motor technology, automatic flexibility compensation technology, laser cutting technology, and information processing technology.
3, poor product quality. The quality gap between China's food and packaging machinery products is mainly reflected in poor stability and reliability, backward modeling, rough appearance, short life of basic parts and accessories, short failure-free operation time, short overhaul period, and the vast majority of products have not yet been formulated. Reliability standards. The international packaging industry attaches great importance to improving the general capacity of packaging machinery processing and the entire packaging system. Therefore, the specialization of packaging machinery parts production is an inevitable trend of development. Many parts and components are no longer produced by the packaging machinery factory, but by some common standard parts. Factory production, some of the special components produced by highly specialized manufacturers, the truly famous packaging machinery factory may be an assembly plant. The product develops into multi-functional and single, high-speed polarization. The ultimate role of packaging machinery is to improve production efficiency and product diversity.
4, lack of development capabilities. China's food and packaging machinery is still mainly imitation, mapping, a little localization improvements, not to mention development research. Product development lacks innovation and is difficult to achieve. Most of the production methods are backward, using the old general-purpose equipment. New product development is not only small but also has a long development cycle. In enterprise management, often heavy production and processing, light research and development, and innovation are not enough, and products cannot be provided in time to meet market demands.
UnionPay analysis:
In response to the above risks, UnionPay has made the following suggestions for the industry:
1. Combine the characteristics of regional layout to promote overall coordinated development
In order to study the development strategy of food and packaging machinery in line with national conditions, it is necessary to study the regional differences that affect the number of food machinery and the development of varieties, and to study and formulate food machinery divisions. In terms of quantity, in addition to sugar in North China and the lower reaches of the Yangtze River, other foods can be adjusted; while in South China, on the other hand, besides sugar, other foods need to be transferred into and refrigerated equipment, which needs to be slaughtered, transported, refrigerated, sheared in pastoral areas. And other mechanical equipment. How to objectively describe the long-term development trend of food and packaging machinery, estimate the quantity and variety of requirements, and reasonably implement the layout of food processing and food machinery manufacturing enterprises are strategic technical and economic issues that are worthy of serious study. Research on food machinery zoning, systems and rational allocation , is the basic technical work for the fixed-item research.
2. Actively develop large-scale enterprise groups
China's food and packaging companies are mostly small and medium-sized enterprises, lacking technical strength, and lacking in self-development capabilities. It is difficult to achieve technology-intensive scale production and it is difficult to meet the ever-changing market demands. Therefore, our country's food and packaging machinery should take the path of corporate grouping, break some boundaries, organize different types of enterprise groups, research institutes, and institutions of higher learning. We must strengthen our integration with enterprises, and we must have the conditions to enter enterprise groups and become enterprise groups. Development center and personnel training base. According to the characteristics of the industry, relevant government departments should proceed from reality and adopt flexible measures to support the rapid development of enterprise groups in the industry.
3. Actively introduce technology and enhance independent development capabilities
The introduction of technology should be combined with technical research and experimental research. It should arrange sufficient absorption and absorption of funds. Through technical research and experimental research, we must master foreign advanced technologies and design ideas, design methods, test methods, and key design data and manufacturing techniques. , Gradually develop self-development capabilities and improve innovation capabilities. The introduction of technology must be combined with the technological improvement of the enterprise, and the corresponding funds for technological transformation should be arranged so that the imported technology can be quickly formed into production capacity and transformed into commodities for market access. Efforts should be made to expand channels and adopt various methods to actively carry out international cooperation, including cooperative development, cooperative manufacturing, talent introduction, and personnel training, etc., to take advantage of others and make up short.
4, strengthen the quality of work to ensure product quality improvement
Under the situation of great development, the food and packaging machinery industry must firmly grasp the link of product quality. Only in this way can it withstand the severe challenges from the market after joining the World Trade Organization. Domestic food and packaging machinery should establish a product quality index system that is compatible with international standards or industrial developed countries standards, and implement the entire process of design, manufacture, inspection, installation, commissioning, and service, and implement a wide range of key products. With license production, companies must strengthen quality awareness and quality management. The relevant government departments shall further support and perfect the existing food and packaging machinery product quality supervision and inspection agencies, and gradually form a national-level product quality supervision and monitoring center, which is responsible for the quality certification of export products in addition to daily quality supervision.
Bank credit tips
Although China's food and packaging machinery industry faces many problems, it also faces huge domestic and foreign markets and better development opportunities. Therefore, banks should focus on industry investment opportunities while avoiding risks. UnionPay believes that banks should focus on the following aspects:
1. In terms of products, China's food packaging machinery focuses on the development of 13 categories of products: 1, oil processing technology and equipment; 2, fruit and vegetable processing technology and equipment; 3, meat processing technology and equipment; 4, dairy processing technology and equipment; 5, convenience foods Technical equipment; 6, beer and beverage technical equipment; 7, ultrafine grinding technology and equipment; 8, extrusion molding technology and equipment; 9, sterilization and curing technology and equipment; 10, microencapsulation technology and equipment; 11, vacuum refrigeration technology and equipment; Fresh-keeping packaging technology and equipment; 13, agricultural products (32.30, 1.30, 4.19%, bar) deep processing of complete sets of technical equipment, such as soybean, rice, corn, potatoes and other deep-processing and comprehensive utilization of equipment. Banks should actively grant credit to such packaging companies in order to obtain the benefits of the development of the industry.
2. In the aspect of enterprises, key enterprises should be supported so that they can develop and grow as quickly as possible. At the same time pay close attention to the adjustment of product structure, and resolutely eliminate the need to provide loans for enterprises with low productivity, high energy consumption, and lagging products. Take the beverage packaging industry as an example. In the next 3-5 years, the beverage market will develop low-sugar or sugar-free beverages while developing existing juices, teas, bottled drinking water, functional beverages, and carbonated beverages. As well as the development of natural and dairy-based health drinks. The development trend of the products will further promote the development of differentiated packaging, such as PET aseptic cold filling packaging, HDPE (barrier layer middle) milk packaging, and aseptic carton packaging. The diversity of beverage product development will ultimately drive innovation in beverage packaging materials and structures. By then, companies that produce differentiated packaging products will benefit, and banks should actively give credit to these companies.
The industry will develop into a distinctive packaging machinery industry with green environmental protection, profit reduction, brand sales, and high quality and high energy. How to better develop the packaging machinery industry based on the tenet of “safety, health, and environmental protection†is an issue that companies urgently need to consider. Enterprises that deviate from the mainstream will eventually be eliminated by a gradually sound market competition system. In this regard, banks should Actively guide the development of industry enterprises to the mainstream of the industry to reduce credit risk and obtain substantial profits.

Four factors intensify the risk of small and medium-sized food packaging machinery companies in China
The current product level of the food packaging machinery manufacturing industry in China is a pagoda. At the bottom is a large number of low-level repetitive products. There are fewer high-end products. According to statistics, there are nearly 6,000 food and packaging machinery manufacturers in the country, of which more than 2,000 are not stable enough. Nearly 15% of the companies convert or close down each year. Only about a dozen companies have output value and sales of more than 100 million yuan, and only 50 companies have annual sales of more than 30 million yuan. 75% of the industry's export products are produced by these 50 companies. Industry insiders believe that the industry is inevitably reshuffled, and small businesses will be phased out and merged in the competition. There are many reasons leading to this situation, including the following four aspects:
