• Mold Design

We would like to introduce Nittoh Co., Ltd.'s "Injection Molding Technology." In the molding division, we are advancing into new fields by leveraging our high-precision optical element technology, such as optical lenses and reflective mirrors. The development of automotive half-mirror products, wearable component parts, and micro-machined parts is a prime example of this, and we provide a unified response from mold manufacturing to injection molding, hard coating, anti-reflective films, and surface treatments such as high-reflective mirrors and half-mirrors. 【Features】 ■ Unified response from mold manufacturing to injection molding, hard coating, anti-reflective films, and surface treatments such as high-reflective mirrors and half-mirrors ■ Support for production from large lots to small lots ■ Detailed responses made possible through collaboration between mold manufacturing and injection molding *For more details, please refer to the PDF materials or feel free to contact us.

• Injection Molding Machine

We refine our core technology, "optical technology," every day, responding to diverse needs from ultra-high-resolution lenses used in high-end precision equipment to DSC lens units capable of producing millions of units per month. We have established a comprehensive system not only for the manufacturing process but also for quality control. Equipped with new inspection devices such as a resolution measurement room with a 200-inch screen, X-ray analysis equipment, drop and vibration testing devices, anechoic chambers, pressure (hydrostatic) testing machines, and temperature testing machines, we deliver high-quality products. **Features** - High-quality product creation that excels in optical technology - A consistent system from research and development to manufacturing - Flexible response to small-scale research and development, such as unique lenses crafted by masters, as well as large-scale projects *For more details, please refer to the PDF document or feel free to contact us.*

We would like to introduce Nittoh's "Vacuum Deposition," which is involved in the development and manufacturing of optical lenses. The "Anti-Reflection Coating for Resin Products" provides stable low-reflection AR coatings and high-durability coatings such as aluminum enhanced reflection mirror coatings for acrylic, Zeonex, and polycarbonate. The "Aluminum Coating for PC-based Resins" can form protective films using CVD on complexly shaped PC-based resin substrates and can apply high-durability aluminum reflection mirror coatings. 【Performance Examples (Excerpt)】 <Anti-Reflection Coating for Resin Products> ■ Wavelength: Transmittance of 95% or more at 450nm to 650nm ■ Adhesion: No peeling when rapidly pulling off Nichiban CT18 ■ High Temperature and Humidity Test: 60℃ × 90% × 1000H ■ High Temperature Test: 80℃ for 50H ■ Low Temperature Test: -30℃ × 1000H *For more details, please refer to the PDF document or feel free to contact us.

• Surface treatment contract service

We have further developed the technology cultivated through the development and manufacturing process of high-performance lenses and are providing it as a technology that can be utilized in various industries, including mold manufacturing. To maximize the mirror surface precision of molds, we have established an electroless Ni-P thick film plating process in-house. You can trust us with complex-shaped molds, including one-of-a-kind original lenses and freeform lenses. [Achievements] ■ Aspherical lens molds ■ Various prism molds ■ Cylindrical lens molds ■ Lens molds with toric surfaces ■ Mirror components, ultra-hard components, etc. *For more details, please contact us.
