METHOD OF RESIN MOLDING AND RESIN MOLDING APPARATUS

摘要

A technology for, in the instance of mold structure having an irregular configuration and having an internal structure with low cavity ratio, carrying out uniform injection of a resin in the mold and shaping thereof. There is provided an apparatus equipped with a container for placing of a resin in its interior, characterized in that the apparatus includes vacuum means for evacuating the interior, drying means for degasifying the interior and heating means for melting the resin and is adapted to sequentially carry out melting the resin at temperature higher than the melting point by the heating means, evacuating and degasifying the interiorby the vacuum means and drying means, thereafter restoring a reference pressure, disposing a mold on the surface of the resin, producing vacuum once more, causing the mold to fall in the resin, allowing the same to stand still for given period of time and restoring the reference pressure while maintaining the resin in molten form.
