Precision Plastic Optical Mold for Lens Base

What is Precision Plastic Optical Mold for Lens Base?

The plastic base mold is a specialized forming tool used exclusively for manufacturing plastic bases in optical lens accessories. Employing specific structural designs and manufacturing processes, this mold processes plastic materials into base components that meet the precision, dimensional, and aesthetic requirements of optical lenses through injection molding and other relevant techniques.

What is the precision requirements for Precision Plastic Optical Mold for Lens Base?

1. Dimensional Accuracy

● Dimensional accuracy of the mold itself: The dimensional accuracy of the mold directly impacts the dimensional accuracy of the produced plastic base. For molds requiring high precision, the dimensional accuracy may be controlled within 0.5um.

● Dimensional accuracy of the produced base component: Since the precision of the mold transfers to the product, the produced plastic base components will also exhibit high dimensional accuracy. Specific values depend on product design specifications and usage requirements, but generally, they are maintained within very low tolerance ranges.

2. Surface Finish

● Surface finish of the mold: The surface finish of the mold directly influences the surface quality of the plastic base. A mold with a high surface finish can produce a smooth, defect-free base component. For plastic base molds in optical lens accessories, the surface finish may reach an extremely high level of Ra0.2nm~0.3nm.

3. Shape Accuracy

● Shape accuracy of the mold: The shape accuracy of the mold is also crucial to ensure that the produced plastic base fully meets the design requirements. This includes the accuracy of all planes, curves, and interfaces of the base.

Application :

The plastic base mold plays a crucial role in the manufacturing of optical lens accessories. It directly impacts the precision, appearance, and performance of the base, which in turn affects the imaging quality and reliability of the entire optical lens. Therefore, designing and manufacturing high-quality plastic base molds is of great significance in enhancing the overall quality of optical lenses.
