Pitch accuracy is below 1μm, surface roughness is below Ra 20nm, and it can accommodate sizes up to 65 inches! There are numerous achievements in molds for light guide plates such as micro lens arrays!
Toray Precision's ultra-fine groove processing has achieved nanometer-order machining by using ultra-high precision processing machines. The light guide plate mold processing and nanoimprint mold processing technology for shaping have realized sharp shapes with grooves and ridges both under 1μm by using processing machines with nanometer-order precision under appropriate environmental conditions of shock resistance, temperature, and humidity (23±0.05°C). The pitch accuracy is below 1μm, and the surface roughness is below Ra 20nm, making it possible to accommodate sizes from 2 to 65 inches, allowing for high-quality processing of various groove shapes. 【Features of Processing Technology】 ■ Shaping Processing → Achieves fine groove processing using high-precision tools ■ Milling Processing → Dimple processing ■ Fly Cutting Processing 【Production Examples】 ■ Light Guide Plate Molds There are achievements in various sizes for watch-type wearable devices, smartphones, tablets, monitors, TVs, etc. ■ Nanoimprint Molds → We accept thermal imprint processing onto films. ■ Micro Lens Arrays ■ Optical Component Molds ■ MEMS ■ Bio-related *For more details, please contact us or download and view the catalog.

Company information
Precision micro-machining technology is increasingly recognized as a common foundational technology that supports modern advanced industries. Since its establishment in 1955, Toray Precision Co., Ltd. has manufactured spinnerets, which are key technologies for synthetic fiber production, and has contributed to the development of the synthetic fiber industry by providing them to fiber manufacturers worldwide, including Japan and Europe and the United States. Meanwhile, the experience and technology gained during this time in precision micro-machining have been widely applied to other industrial sectors. Precision machined components are incorporated into critical parts of aircraft, industrial robots, measurement and control equipment, etc. Additionally, the specially developed and designed fluid nozzles have demonstrated their functionality as important components in various industrial machines. The ultra-precision micro-machining technology, boasting sub-micron precision, is also utilized in the optical communication field, which is essential for realizing a highly information-oriented society. We have also commercialized various optical devices, including optical components such as ferrules and adapters. As a pioneer in ultra-precision micro-machining technology, we will continue to contribute to society by delivering high-precision, high-quality products.
