Injection molding of optical products requires extremely high transmittance, strong light diffusion performance, and no light shadow, no illusory light, and dimensional stability. And it has a positive ignition level from UL94V2-V0, which means that the hot runner must have uniform heat distribution and ensure consistency in each injection molding. Plating hot runner can reduce the residence time of materials during the process, ensuring optimal melting control and producing clear and stable optical components.
