What, it can be this transparent with a 30μm hole!! Achieving a high aperture ratio of 30%!
Traditionally, porous materials have primarily been associated with meshes and porous substances, but there are challenges such as uneven pore sizes and clogging, which become even more pronounced with fine pores. Therefore, Toray Precision Co., Ltd. has utilized laser processing technology to achieve narrow pitch processing by making the pore cross-sectional shape approach straight, instead of the usual tapered shape in the depth direction, on metal plates (t0.1mm) such as Ti and SUS. 【Features】 ● High open area ratio: 30% at φ30μm ● High precision: Pore diameter accuracy (σ) is approximately ±1μm ● Reverse washing is possible due to aligned straight pores ● Reasonably priced as a high open area porous plate with fine pores For more details, please contact us or download 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.
