Temperature and packing pressure are the major parameters that affect the replication characteristics of micro injection molding technique using a demolding mold. the principle is that the mold in order to control temperature by heating patterned stamper was applied to obtain better pattern replication characteristic. in this study, using a nickel stamper which has micro pattern, release force were measured in the process of injection molding. in conclusion, the more packing pressure rises, the more release force increases. in addition, increasing the cooling time cause larger shrinkage rate and smaller release force.
