The production process and characteristics of resin lenses

The manufacturing of lenses is mainly divided into three modules: substrate, hardening, and coating. The production steps of substrates are the most complicated. Let's take a look at the process of lens production.

The first is the lens ingredients, mixing the ingredients with additives, and then degassing the mixture. Secondly, the substrate is assembled, and the qualified molds are combined in different ways with sealing rings or tapes. Then it is filled, and the configured raw materials are injected into the assembled mold from the sealing ring injection hole by manual or mechanical methods, and the sealing of the seal is checked to ensure that the quality meets the requirements. Then the filled mold is heated and cured, and the mold is separated from the substrate after curing, so that the blank lens is formed. After trimming the blank lens, it is cleaned with ultrasound, and finally secondary curing is performed to make the dents on the surface of the lens more flat, and then inspected and put into storage.

The above is the basic production process of lenses. The advantages of Resin Lenses are lightness, good impact resistance and not easy to break. Lenses can be colored and hardened according to the needs of the market and consumers. After hardening inspection, they are hardened and cured again to achieve the effect of matching with clothing and makeup, which is deeply loved by young people. Not only that, resin lenses also support the selection of a variety of lens film layers, such as anti-blue light, anti-fatigue, anti-ultraviolet, etc., which increases the practicality of the lenses and thus has a protective function .

Resin lenses are both beautiful and practical, but they also have unavoidable shortcomings. The surface wear resistance and chemical corrosion resistance of resin lenses are relatively weak, and scratches are easy to appear. The lens is easy to deform when it reaches 80 degrees Celsius, affecting the optical performance.

In general, the lens itself has a lifespan and needs to be replaced regularly. Under normal wear, resin lenses are a very cost-effective choice. If you have a need for lenses, please contact us.
