Presion Plastic Optical Mold for Lens Barrel

What is Presion Plastic Optical Mold for Lens Barrel?

The plastic lens barrel mold is a specialized tool used exclusively for the production of plastic lens barrels, which are components of optical lens accessories. This mold, through its specific structural design, employs injection molding, compression molding, or other forming processes to transform plastic materials into lens barrel components that meet the precision and aesthetic requirements necessary for optical lenses.

What is the precision requirements for plastic lens barrel molds ?

The precision requirements for plastic lens barrel molds are typically dictated by the specific needs and specifications of the optical lenses they are intended to produce. Generally speaking, due to the extremely high demands on imaging quality of optical lenses, their accessories such as plastic lens barrels also necessitate considerable precision. Below are some detailed specifications regarding the precision requirements for plastic lens barrel molds:

1. Dimensional Accuracy

● Mold Dimensional Accuracy:  The dimensional accuracy of the mold itself is of utmost importance to ensure that the produced lens barrels conform to design standards. The dimensional accuracy of the mold may reach micrometer-level precision (μm), with the mold core's dimensional accuracy often controlled within 0.5μm or less.

● Produced Lens Barrel Dimensional Accuracy: The dimensional accuracy of the molded lens barrels is equally crucial, often requiring exceptional levels of dimensional accuracy and eccentricity, with eccentricity possibly requiring less than 2μm.

2. Surface Quality

● Surface Finish: The surface finish of the mold directly impacts the surface quality of the produced lens barrels. The mold's surface finish can achieve nanometer-level smoothness, with the mold core's surface finish reaching up to Ra0.2nm~0.3nm, ensuring a flawless, highly polished surface on the lens barrels.

3. Other Precision Requirements

● Mold Processing Evaluation

● Mold Materials and Heat Treatment

Application :

The plastic lens barrel mold plays a vital role in the manufacturing of optical lens accessories. It directly impacts the precision, appearance, and performance of the lens barrel, which subsequently influences the imaging quality and reliability of the entire optical lens. As such, designing and manufacturing high-quality plastic lens barrel molds is of great significance in enhancing the overall quality of optical lenses.
