The end of spiral fan development stage
Since the reform and opening-up of the spiral duct blower, the spiral duct machinery manufacturing industry has achieved unconventional development through large-scale introduction of foreign technology and equipment, and has completed the road of advanced countries for many years in a relatively short period of time.
One of the important reasons for spiral duct manufacturers is that they can make use of ready-made technology and management, give full play to the advantages of latecomers, and promote the rapid improvement of production factors. With the end of the catch-up development stage, the available foreign ready-made technology space is compressed, and the general level of technology and equipment can no longer meet the needs of the new stage, and the urgent need of technology often involves the competitive advantage of advanced countries, so it is more difficult to introduce technology and equipment.
