Very small details:
The overmolded layer of TPU is only 0.4-1mm thick, and there are many small V-slots to further secure the overmolded layer from coming apart. Many small details need to be made precisely according to the design.
High precision of the molded parts:
To allow the parts function properly with the lens, these parts need to be made flat and with the minimum bend, warpage or distortion.
