Chalcogenide glass is widely used in infrared area for its cheap and good performance of infrared transmittance. Compare with the traditional material signal crystal germanium, zinc sulfide, zinc selenide etc. Chalcogenide glass is suit for precision molding for the low soften temperature which is suit for large mass industry production. And precision glass molding(PGM) is a kind of technology involving the molding machine, mold material, the glass, molding parameters etc. So the researches on the forming characteristic of precision glass molding are necessary. In this paper, the FEM simulation is used to assist research of the forming characteristic, especially the friction coefficient effect on the forming. At the last the surface profile compensation and micro-replication of molding is discussed.
