Reduce Taiwan's machinery exports
HC plastic mesh As ordinary Plastic Machinery Control is relatively simple, but mostly stand-alone operation of the machine, limited by the level of mechanical reliability, plastic machinery reliability requirements of the control system is not high, so a dedicated controller, the embedded product development to meet the vast majority of users demand, the price is great, and therefore, in the industry are widely used, especially in Injection molding machine The more common applications, blow molding equipment in the application of a relatively high proportion. In the extrusion equipment, as PLC's reliability, short development cycle and application of mature, PLC dominated applications. Currently in the industry to use more of PLC brands Siemens, Omron, Mitsubishi, NAIS, LG and so on. Siemens offers a series of plastic machinery based on PLC controllers.
With the development of plastic machinery technology, the controller is not a simple motor control, but including the melt temperature, injection pressure, injection speed, packing time, cooling and hydraulic circuits of the various parameters of the integrated control. The past, most with open-loop control, the current direction is to the closed-loop control. New equipment to control the control and responsiveness has been further requirements of the traditional controller based on embedded products can not meet these requirements, so new equipment and large equipment to the main PLC. This kind of high-end PLC and the use of large equipment, special controller used in the situation of low-end device in the next three years in the plastics machinery industry will not change. Competitive price to enter the largest number of General Plastics Machine controller market premise.
Characteristics of the production process of plastic machinery with very large energy saving potential to injection molding machine, for example, injection molding machine generally consists of clamping process, Injecting, melting, holding, cooling, mold and other stages , each stage requires a different pressure and flow. For the pump motor, the injection molding process is a changing load conditions, the quantitative pump hydraulic system, the pump motor at a constant speed to provide constant flow, the excess return of hydraulic oil through the relief valve, this process is called high-pressure section stream, this return will result in energy losses. Inverter Use to solve this problem by adjusting the pump speed, pump injection molding machine can produce different stages of the appropriate oil pressure, maximum energy loss reduction. The first inverter in the plastic machinery is used on a number of end users, system integrators, providing them with energy-saving plastic machinery conversion program with remarkable results, so more and more customers use plastic mechanical transducer transforming their equipment. Respond to this demand, plastic machinery manufacturers have begun to use the converter in the plastic machinery, plastic machinery, users can choose models with a frequency converter. To reduce the time investment, currently the majority of users still chose not to bring the inverter plastic machinery, they can use in the subsequent conversion process for energy saving.
