A study on the displacement analysis in the injection moulding for the camera-phone

Smartphones are currently the most popular electronic devices with high volume production activities driven by high demand and requirements for rapid turnaround time. The changes of displacement were analysed according to a variable of the gate size and runner system. The radial type and gate with large size were shown that better results in displacement. While the design and production of lenses, the key component of a camera, still need to be improved, the current technology has run into its limit with regard to trends in size and weight reduction. In this study, an injection moulding analysis was performed on plastic lenses that are widely employed for smartphone cameras. Specifically, the displacement of lenses at the time of injection moulding was studied by varying the gate size and runner system.
