Technical Review for Special Molding System

The focus of discussion is on an investigation regarding special molding and the environment that was conducted for 4 years starting 1999. The main reference literatures used by the author are: molding technology, lecture collections on molding engineering, JACT news, AFS Transactions, Foundry Management and Technology etc. in regard to environment issues, the new air conditioning technique proposed by Scholz et al is discussed. In this system, air mass balance, real time forms of atmospheric pollutants, area sampling and trace gas simulation for pollutant dispersion etc are reviewed. The effective performance of FISA ultrasonic mold cleaning that was developed by automotive die cast manufacturer; Erlau Company of Germany is reviewed. Additional topics of discussion include, organic self-hardening molds and gas hardening resin molds as well as evaporative pattern casting techniques.
