Abstract
Precision glass molding (PGM) technology is a cost-effective manufacturing process for high precision optical elements with complex surfaces. With this processing technology, one or more pieces of lenses may be produced through one-step molding. Due to the high efficiency of the replicative process, PGM has found wide applications in high volume production of optical elements. At present, it has been well developed and widely used in mass industry production in Japan and South Korea, but in China PGM technology research is still in the elementary stage. To develop the PGM technology, we need to conquer several technical difficulties, such as the melting technology of low Tg glasses, highprecision mold design and the corresponding machining technology and the coating technology for the molds. In this paper, we discussed the PGM technology as a complete manufacturing process, focused on the technical difficulties mentioned above, and introduced the development directions for this technology in China.
