Injection mold machine works in place, the output signal to trigger mold protection, the latter taking the mold cavity as mold continuous monitor, monitor whether thimble piece molded top out and whereabouts. When the workpiece is completely monitored whereabouts, mold protection a confirmation signal back to the injection molding machine to begin the next cycle. If a piece does not fall within the set time or debris between the mold, mold protection abnormal signal is issued mold injection machine vision surveillance system, and the police action to stop the injection molding machine. Due to the increased time and speed shearing mold protection monitors, 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 mixing, only use the last resort, pre-mixed with the raw material and the toner, and then use 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.
