Method of controlling holding pressure in injection molding and apparatus therefor |
摘要 |
A method of controlling holding pressure in an injection molding operation and an apparatus therefor, wherein the quality of molded products can be controlled with a high accuracy without the need for a pressure sensor in a mold and without requiring any additional data such as the thickness of a molded product, the effective heat diffusion rate, and so on. Further, a method for estimating resin temperature in injection molding and an appartus therefor, wherein in-mold resin temperature in a holding pressure and cooling stage is estimated during injection at a high speed and with a high accuracy.
