Title:
INJECTION MOLDING METHOD FOR RESIN MOLDING AND METHOD FOR SPECIFYING MOLD-CLAMPING FORCE
Document Type and Number:
WIPO Patent Application WO/2015/186417
Kind Code:
A1
Abstract:
An injection molding method for a resin molding closes a stationary mold (201) with a movable mold (202) at a prescribed mold-clamping force and, after filling melted resin in a cavity (1) formed between the stationary mold (201) and the movable mold (202), performs pressure maintenance and cooling, and separates the stationary mold (201) from the movable mold (202). The injection molding method performs mold-clamping, filling, pressure maintenance, and cooling on the stationary mold (201) and the movable mold (202) using a previously specified mold-clamping force at which the pressure inside the cavity (1) during the cooling step is a minimum and which is based on a sample specified from among multiple samples (T1, T2, T3).
