This classification is based on the specific optical components the molds produce, which directly determines the mold’s design standards and precision requirements.
- Lens Molds
Specialized for manufacturing various optical lenses, such as camera lenses, eyeglass lenses, microscope objective lenses, and automotive headlight lenses. These molds require ultra-high surface finish (Ra ≤ 0.001 μm) and strict dimensional tolerance control to ensure light transmittance and imaging quality.
- Prism Molds
Used for molding optical prisms applied in binoculars, spectrometers, and laser devices. The molds need precise angle machining (tolerance ±5″) to achieve light refraction, reflection, or dispersion functions.
- Optical Film Molds
Designed for producing thin optical films, including polarizing films, anti-reflective (AR) films, and light guide plates (LGP) for LCD screens. The mold cavity surface has micro-nano structures to realize light diffusion and uniform transmission.
