Due to the increased time and speed shear, the melt temperature is raised, it may play a shadow color deviation, the need for toning if necessary. When using the above approach can not solve the problem, only to die or transferred to a larger or better quality to produce a newer machine, injection molding machine is too small or too old are the major cause of the problem is difficult to solve mixing. It can not solve the problem of mold monitor mixing, only use the last resort mold injection machine vision surveillance system, pre-mixed with the raw material and the toner good injection molding machine mold protection, then the pre-plastic pull tablets machine will pull them grain. After pulling raw grain after almost blending will not have problems, but still need to pay attention to changes in color. Machine vision inspection is characterized by flexibility and increase the degree of automation of production. In some not suitable for manual operation of hazardous work environment or the artificial vision can not meet the requirements of the occasion mold, commonly used to replace the artificial vision machine vision; at the same time large quantities of industrial processes, using artificial vision inspection efficiency is low and the product quality precision high, machine vision detection method can greatly improve production efficiency and automation of production. Machine Vision and easy to implement information integration, is the foundation technology for computer integrated manufacturing.
