外文资料（英文） high dynamic drive concept of the injection molding machinein an increasingly competitive market environment, the injection molding machine whether or not can best adapt to specific production of injection molding machine manufacturer is essential. when in the selection of a suitable injection molding machine, the consideration standard not only include size of plastic parts ,geometry shape as well as the size of injection molding machine ,but also the quality of plastic parts and production efficiency. concept-driven of injection molding machine have an important impact on performance of choice and in the field of complex applications of injection molding machine.based on the quality characteristics of injection molded parts, processors can often be drawn to the concept of injection molding machine and its drive requirements. however, given the size of the injection molding machine， through the concept of the driven idea can be used to measure the energy density in order to ensure maximum productivityin general，all netstal injection molding machine of high energy density can be applied to variety driven idea of any injection molded parts, thus limiting the choice of an established product categorywhen select the best products for a variety of injection molding machine, this important factor make netstal injection molding machine shown unique application advantages.synergy and elion series injection molding machine by right of theirselves functions, standards and high-efficient operating performance became the fast cycle injection molding of first-class equipmentthey have many advantages ,including the parallel exercise capacity，excellent performance of the measurement accuracy, as well as injection molding capabilityinjection axis and measurement axis both possess high dynamic regulatory function，can be extremely precise control of injection speed and injection-pressure switch pointtherefore，we can ensure that a higher injection speed and shorter braking distances to switch to the state of keeping pressure. in addition, the high reproducibility of the machine applicable to many complex applications. hydraulic drives of synergy series injection molding machine generally have a very high energy densityfrom today s point of viewthe assumption that the cost differences and the ability to run the same space would have required a lot of different size in the machine should be looking to ensure the best standardsdriven boundaries in addition, the hydraulic system can easily generate the energy for along time, especially in the injection device in the packing pressure and nozzle pressure contacts for long-term needs of the hydraulic system pressure to provide a guarantee. pressure in the injection pressure to the pressure of the process of conversion，from the pressure generated by the set injection pressure and pressure cycle of the pressure at the end of the rapid decline in pressure, which is the quality of plastic parts is absolutely vitalup to 40000 bar (1bar = 105pa) the decompression speed is very common and can be regulated through control of high dynamic valve to achieve .dynamic valve control system greatly slow up ，and so that the machine was excellent reproducibilityhydraulic injection molding machine with mold cavity and the need for a large number of highenergy density of the products have been really concerned about this is because the force for more than 3000kn mold injection molding machine，the use of hydraulic injection molding machine produced products required for the rapid injection of high energy density is quite easy，in many cases will be highly effective as a mixture of electronic measurement-driven solutions therefore ，the total energy consumption can be achieved with the current standards and efficient production system . electric injection molding machine mainly enhanced by virtue of their superior dynamic performance and leaves a deep impression ， which established the reproducibility of the process is especially obvious in many cases ，can be achieved 10 times in the injection molding machine hydraulic weight accuracy ， and reduce energy consumption by 70 electric braking energy recovery process， especially in the injection cycle， the total energy consumption can be an important part. and the other compared to allelectric injection molding machine， elion series injection molding machine to play that stretched to the limit: the energy generated by braking the process of transition directly into the circuitthis means that do not have the braking energy into heat，but is stored in the capacitor circuitfor example ，when plastics took place in the course of mold opening ,the energy generated by braking circuit can be learned from the transition of the energy required for rotating screw therefore, the energy is not from the power supply network, and generates a corresponding reduction in power consumption. flower production in relation to trials ，from the brake circuit of the transition process of the direct energy requirements account for 15of the energy cycle ，and resulted in the total energy consumption 0.25 kwhkgmelting plastic on the calculation of the energy required to show that: this is only required for each cycle is slightly less that the total energy similarly, the energy required to drive the machine almost all from the axis of the braking process ，not through the braking resistor into heatcompared with the hydrau
