Micro-injection molding applied to production of optical products-example of lens

Abstract Injection moulding is essential for the mass production of plastic products. This study focuses on the application of micro-injection moulding to produce optical products using self-designed moulds and core structure processing techniques. The chosen material for injection is acrylic PMMA, renowned for its excellent finish, weather resistance, heat resistance, transparency, and gloss. Post-injection, the products were evaluated for their optical properties. The TRIZ analysis provided insights into problem-solving directions and cost reduction strategies. The implementation of a one-mould, four-cavity design enabled mass production, significantly enhancing production efficiency.
