Experimental and simulated analysis of glass deformation and filling modes during partial-filling hot embossing process

In the partial-filling hot embossing process (PFHE), the stress distribution and geometry of a glass micro-lens influence its optical performance. The deformation behavior of glass is very complex during PFHE. In order to investigate the final shape and stress distribution of glass micro-lens during PFHE, both simulations and experiments were conducted. The experiment results revealed that different glass squeeze flow conditions gave rise to...
