The current competitive landscape of the inverter and servo industry is dominated by foreign capital, each occupying about 80% of the market share. From the megatrends, ZTE's editors believe that the best domestic industrial automation companies will lead the overall share of domestic brands in the future. The low-voltage frequency conversion and servo industry will grow at a rate of 10% in the next 10 years (slightly over GDP). By 2020, the market size will be 41.7 billion yuan and 13.8 billion yuan respectively. The country's major vacant market needs a large number of plastic machinery and accessories manufacturers. Continuous research and development and innovation. At present, the technology of Huichuan is one of the largest, which does not want to match the domestic competitive environment.
China is a big country in the injection molding machine industry. Each year, 80,000 to 90,000 injection molding machine equipments are added. The power of injection molding machine servo drives is generally relatively large. It is expected that the company's servo system business revenue in 2011 will still be expected to double. The development of China's inverter is even more twists and turns:
First, foreign brands monopolized the market. In the 1990s, China's imported high-voltage frequency converters were mainly supporting key projects. At this time, domestic customers did not realize the energy-saving effect and the product price was relatively high.
Second, domestic companies have discovered the high-voltage frequency conversion market and sought technical breakthroughs. However, they face two major challenges: customer distrust and product instability. Although the selling price is less than half that of foreign brands, due to performance problems, domestic companies can only be small. Customers get orders.
Thirdly, domestic companies have made breakthroughs. First, after accumulating, technically it is no longer a problem. Reliability has met customer requirements and the brand is gradually established. Foreign brands generally lag behind local companies in service, giving domestic companies a good opportunity for development. German domestic brands, such as DFW, have become market leaders.
Fourth, domestic enterprises are fully blooming. When large-scale customers realize that foreign brands do not monopolize the market, they will invest more in domestic enterprises and accelerate the process of localization.
The development trend of the frequency converter in China is: the exchange of the drive, the high frequency of the power converter, the control of the digital, intelligent and networked so our country would like to have a bigger role in the injection molding machine, the development of the inverter And technology updates are indispensable!
For the plastics industry, electricity consumption is a major part of its production costs, and injection molding machines are one of the main energy-consuming equipments of plastics production plants: the vast majority of injection molding machines currently belong to hydraulic-driven injection molding machines and hydraulic transmission systems. The power is provided by the motor driven by the motor. During the injection molding production cycle, the injection molding machine needs different flow and pressure in different processes, and must rely on flow valves and pressure valves to regulate the flow and pressure required for different processes. The load on the hydraulic system varies greatly. Due to the non-adjustable output power of the metering pump, excess energy can only be consumed in the baffle, leakage of the oil circuit, and temperature rise of the oil. The collection of plastics summarizes the fact that this not only exacerbates the wear and tear of various valves, but also causes the phenomenon of high oil temperature, excessive motor noise, and shortened mechanical life. And usually in the design, the capacity of the user's oil pump motor design is much higher than the actual needs, there is a phenomenon of "big horse-drawn cars," resulting in a lot of energy wasted. Therefore, the promotion of the application of AC variable frequency speed control devices in injection molding machines is of great significance for reducing energy waste and reducing production costs.
The advantage of the inverter in the energy-saving transformation of the injection molding machine is even stronger. When the frequency conversion of the injection molding machine is connected, the original computer control system of the injection molding machine and the hydraulic circuit of the hydraulic drive system and the Y step-down start-up circuit of the motor are not Change, using frequency conversion energy-saving/commercial-frequency operation conversion control method, to avoid affecting the normal production in the event of a failure: when changing the mold only need to change the working procedure of the injection molding machine computer board, without any adjustment to the inverter.
