Gentex - Manufacturing Versatility

Manufacturing Versatility

Gentex can produce a wide range of optical formats to meet your specific application needs. Regardless of mold size or type, our automated production environment provides precise cycle time control and a stable thermal environment that results in excellent part-to-part uniformity and high manufacturing yields. A self-contained clean environment is used for resin transport to ensure extremely low levels of contamination and for application of anti-scratch hard coatings or other specialty coatings. Flow coating of individual surfaces is also available.   For embedded absorptive dyes, Gentex mixes and compounds these powders and resins in both a laboratory scale or at industrial scale.
