Machining an Injection Mold for Acrylic Lenses - Benchtop Molding Process

Watch a 21-minute video demonstrating the process of machining an injection mold for acrylic lenses. Learn about the challenges of injection molding as the presenter tackles a "simple" double convex singlet lens project using a benchtop injection molding machine. Explore the intricacies of machining, injection molding theory, and the practical aspects of molding acrylic lenses. Discover how to analyze stress concentrations in the molded lenses using polarized light and birefringence. Get insights into using a new polycrystalline diamond (PCD) end mill and learn about the capabilities of the Proto-Ject 150HP injection molding machine, including its injection pressure, shot size, and hydraulic clamp specifications.
