Application of ESTUN AC Servo System in Computer Flat Knitting Machine
Servo analysis in the development of fully automatic computerized flat knitting machine market
China's knitting industry is known as the world's factory. In this huge factory, it is conservatively estimated that there are more than 40,000 computerized flat knitting machines, more than 120,000 electric flat knitting machines, and the number of hand flat knitting machines is over one million. In the past three years, China's average annual import of computerized flat knitting machines has remained at 4,000 to 5,000 units. From these figures, it can be clearly seen that the market potential of fully automatic computerized flat knitting machines is very large.
In China, there are more than 50,000 processing plants engaged in the production of sweaters. From this figure, there is less than one computerized flat knitting machine per factory. The processing plant with the largest number of computerized flat knitting machines has nearly 1,500 computerized flat knitting machines. From these figures, we can see that the popularity of computerized flat knitting machines is not high. Many sweater factories have not used computerized flat knitting machines, but now they are developing from hand-held flat knitting machines to computerized flat knitting machines. The tide has come, and under this trend, the market space of computerized flat knitting machines has been greatly expanded. Driven by market demand, more factories will start using fully automatic computerized flat knitting machines.
From the perspective of the demand of the international market, in the context of the continuous appreciation of the renminbi and the increasing trade barriers, it is difficult to obtain low-value-added processing through cheap labor, only from the quality of products. Improving competitiveness is the real channel for profit. The computerized flat knitting machine can achieve a level of craftsmanship that is difficult to achieve than a hand flat knitting machine. Therefore, the use of computerized flat knitting machines can produce higher value-added sweaters, so that manufacturers can make greater profits.
In summary, we can clearly determine that the market space of computerized flat knitting machines is huge, and the demand for computerized flat knitting machines in the domestic market will become larger and larger. At present, the single (dual) system in the domestic computerized flat knitting machine industry is equipped with two sets of AC servos, the main servo is used for the head drive system, and the shaker servo is used for the needle bed shifting system. With the increasing demand for computerized flat knitting machines, servo as a major precision transmission accessory component will usher in a vast and huge market space.
