INJECTION MOLDING METHOD

摘要

In an injection moulding method, during filling of a cavity with molten resin, molten resin is filled in a way that a resin pressure in a mould is gradually increased within a range in which a resin pressure in a mould is lower than a max. value required during dwell after filling. After that, the resin pressure in a mould is further increased from the increased resin pressure mentioned above to effect the dwell.
