Method for supervision of injection molding by use of waveform of internal die pressure |
摘要 |
A method for the supervision of injection molding including monitoring an internal die pressure of molten resin flowing through a resin passageway in a mold to form a monitored waveform; displaying the monitored wavefrom together with a predetermined reference waveform on a display unit such as a CRT, and comparing the monitored waveform with an allowable value of the reference waveform to determine any abnormality caused in a molding process. The injection molding can be supervised with accuracy on the basis of the reference waveform representing the optimum internal die pressure, thereby increasing the quality of molded articles.
