In recent years, China's plastic machinery has become one of the most rapidly developing industries in the traditional machinery manufacturing industry, according to relevant data, the annual demand for plastic machinery industry is 8.5 billion yuan. According to experts, at least in the next 15 years, China's plastic machinery industry will continue to maintain rapid growth.
In the rapid development of the plastics industry today, injection moulding machines occupy an important position both in terms of quantity and variety, and their total production accounts for 20%-30% of the entire plastic moulding equipment, becoming one of the fastest growing and most produced types of plastic machinery. Injection moulding machines can be subdivided into vertical injection moulding machines, horizontal injection moulding machines and electric injection moulding machines, etc. The all-electric injection moulding machine is the main type of electric injection moulding machine and is currently the most promising type of plastic machine.
The all-electric injection moulding machine was first published by Battenfeld in Germany and commercialised by Nissei Plastics. It is a type of injection moulding machine that is powered entirely by electricity and can inject thermoplastics into various moulds.
The all-electric injection moulding machine is fast, accurate, stable, quiet, energy efficient and clean, making it a new revolution in injection moulding machines. From general civil and industrial applications such as silicone products, PET containers, automotive parts, cosmetic containers, household containers, precision gears and the list goes on, the fast, stable and quiet advantages of all-electric injection moulding machines are used in the precision injection moulding market, such as semiconductor parts, information computer products, optical lenses, liquid crystal guide plates, IC cards, electronic material parts and much more. In the advanced micro-injection technology, the all-electric injection moulding machine will shine, such as biochemical, medical, micro-electro-mechanical, information, optoelectronic and precision measurement components.
Compared to other types of injection moulding machines, all-electric injection moulding machines have the following advantages.
Energy saving
Conventional hydraulic injection moulding machines have oil pressure control losses, pipe losses, valve resistance and other flow losses, as well as pump volumetric efficiency, friction losses, etc., which are particularly noticeable at high flow rates. The servo motor of an all-electric injection moulding machine does not rotate during standby, and there are no flow losses, no control losses and very low hysteresis losses during operation, so energy losses are low and not related to speed. Most all-electric injection moulding machines use ball screws to convert the rotational motion of the servo motor into linear motion, and the frictional resistance of the ball screw is much lower than that of the hydraulic cylinder, and there is no cooling system, so the overall efficiency is much higher than that of the hydraulic machinery.
High precision and repeatability
Compared to other types of injection moulding machines, all-electric injection moulding machines are characterised by high precision and repeatability, and high precision injection moulding can be easily achieved. The pressure during injection of all-electric injection moulding machines is fed back to the injection system through a high-precision pressure sensor, which is directly connected to the screw, reducing the errors caused by intermediate links and sensing fast and with high accuracy, which makes the back pressure control of all-electric injection moulding machines more accurate.
Intelligent
With the further maturation of the plastics processing industry, higher demands are being placed on the plastics machinery industry. In order to achieve the goals of high efficiency, precision and energy saving, intelligence has become the new direction for the development of the plastic machinery industry. All-electric injection moulding machine equipment unit automatic control, closed-loop control of parameters, process intermodal online feedback control and other electronic and computer technologies are widely used, especially PC-based open, modular control technology is increasingly favoured by plastic machine manufacturers. In particular, the PC operating platform, while greatly improving the ease of use of the operator, with the help of powerful network functions, manufacturers can achieve remote maintenance of the machines sold, which will have a significant effect on improving production efficiency and reducing production costs.
Conclusion
All-electric injection moulding machines have their shortcomings compared to traditional injection moulding machines, such as a lack of price advantage, and the wear and tear of the mechanical components of all-electric injection moulding machines will lead to a reduction in injection accuracy, inconvenience and high maintenance costs. However, as a high-end product in the plastic machine industry, all-electric injection moulding machines have gained more and more popularity among manufacturers for their excellent performance, cleanliness and control characteristics, and in recent years, the share of all-electric injection moulding machines in the international market has been increasing. With the common application of high-precision plastic parts and the reduction of production costs, the future development space of all-electric injection moulding machines is bound to be huge.
