Injection molding is a highly efficient method for mass-producing plastic lenses with complex geometries and high precision. It involves melting plastic resin and injecting it under pressure into a mold, where it cools and solidifies into the desired lens shape. This process allows for the creation of lenses with various features like aspheric surfaces, freeform surfaces, and diffractive structures. These are used in critical applications in the automotive, defense, security systems and other commercial applications. Here is a peak at our injection molding facility:
