【正文】 ucts, less postprocessing, processing characteristics of the plastic variety, since its inception has grown rapidly, the current full Over 80% of the world39。s hardware I / O channels in a single road, road, or dozens of way more than a decade as a unit module carried out dozens of pointtohundreds of thousands of pointpoint expansion and working. PCC in the industrial control powerful advantages, and demonstrate the programmable controllers and industrial control puters and DCS (Distributed Industrial Control System) technology, the development trend of convergence, although this is still a relatively young technology, but in its more e more and more application areas, it is increasingly demonstrating its potential for development can not be underestimated. For the injection molding machine, the current widespread application of the PLC control system, but as technology advances, personalized, customized products, growing demand for injection molding machine control requirements more plex, higher and higher precision, PCC as a more advanced control system, will gradually occupy a certain market share. On the other hand, for the future workbased production requirements, obviously, PCC control system more petitive edge, so we have reason to believe, PCC control system will be in the future take place in the field of injection molding machines.

Precise temperature control in precision injection molding that help improve product quality and availability of raw materials is a very important indicator. In the plastic processing, temperature control include barrel, nozzle and mold temperature control. Barrel temperature of the barrel surface heating temperature, due to relatively thick wall barrel, so the choice of thermocouple detection point is critical, and different test points on the temperature curve is a large difference. Therefore, parallel detection of doublepoint, namely, surface and deep in the barrel at the same time set the thermocouples, will be relatively stable temperature curve is conducive to temperature control accur
