Abstract

Abstract: The rapid development of plastic parts brought new challenges to precision injection mold design. The advantages and working principle of porous material in precision injection mold were reviewed in this paper. Currently, porous materials were employ in injection mold as vent system, cooling system, demolding system, vacuum system, and In Mold Labeling (IML) technology. The strength, porosity, pore size and distribution, surface topography control, and machinability constituted the hot topics. Low cost and mass production will be the development trend in the near future.

Key words: precision injection mold, porous material, vent, demolding, In Mold Labeling
