光学塑料元件低压注射成型技术的应用

Applied of low pressure inject molding technology in optical plastics

光学塑料元件低压注射成型技术是相对于传统注射技术的一大改进。它包括压缩注射成型、低压高速成型、注入气体注射成型和降低模内压力成型。它的主要优点是降低压力、降低能源消耗、降低成本、提高工效、提高光学塑料元件质量。

The progresses made in the classical injection technology by low pressure injection molding technology of optic plastics are mainly discusses. It involves presuure injection molding; low pressure high speed molding; inject gas injection molding and lowering mold in pressure molding. The advantages of the technology are lowering pressure and lowering cost, raising productivity and quality. It is great advantage for development of optical plastic aspherical lens in China.
