In mechanical processing, it is extremely difficult to pursue tact time and improve processing quality. The technology that solves such concerns is "Laser Microjet." Laser Microjet = Water Laser Processing is a method that guides a laser to the material using a water jet as thin as a human hair. 【Processing Target Materials】 - Ceramics (alumina, aluminum nitride, silicon carbide, etc.) - Silicon - Metals (copper, aluminum, stainless steel, alloys, etc.) - Diamond, etc. 【Processing Content】 - Holes - Grooves - Cutouts - Shape processing, etc. By utilizing the total reflection phenomenon at the interface of the layered water jet, the laser beam is irradiated onto the material. Since the water jet continuously strikes the target workpiece, the thermal effects of the laser are minimized to the extreme, preventing phenomena such as burn marks due to material melting and resulting in a high-quality processed surface finish. This innovative processing technology achieves high precision and high aspect ratio cutting, hole, and groove processing of materials such as metals and ceramics. *Laser Microjet is a trademark of the processing technology developed by SYNOVA.

1: World-class beam quality The fundamental single-mode fiber laser achieves the world's smallest core diameter (14 µm) and possesses the highest level of beam quality. Additionally, the multi-mode fiber laser maintains class-leading quality without significantly degrading the single-mode beam quality, thanks to its unique beam coupling technology. This high beam quality enables equivalent processing performance at lower optical output compared to conventional lasers. 2: High resistance to reflected light When processing highly reflective materials like copper, strong reflected light can return into the fiber, potentially leading to the failure of the oscillator. Our unique measures against reflected light have been experimentally confirmed to prevent damage to the oscillator even under vertical incidence. 3: Flexible beam shaping technology using an optical head with beam mode control function The greatest feature of the beam mode control technology is the freedom of mode design. It allows for the modification of the beam mode into any desired shape, achieving optimal patterns and intensity distributions for the processing material. 4: Sputtering suppression achieved through beam mode control Even under conditions where sputtering typically occurs, it is possible to reduce sputtering by using beam mode control technology.

In ceramics, traditional manufacturing methods have limitations on the shapes that can be produced, and molding methods using precision molds are costly and time-consuming, with similar restrictions on reproducible shapes. This time, we have achieved manufacturing using a 3D printer with light curing technology. We can create various complex shapes that are smaller than the size of a palm. For example, alumina particles smaller than 1 micron are mixed with UV-curable resin to create a slurry using a stirrer, and then shaped by irradiating UV light. The particle size is very fine, below 1 micron, and due to the advanced stirring technology used, the particles are distributed very uniformly, resulting in a very smooth finish and surface after firing. We not only offer proposals and sales of the equipment itself but also provide contract processing based on 3D data received. The materials include information on manufacturing methods and examples of shapes, so please check them as well. If you have any questions, please feel free to contact us.

Alumina ceramics, even as insulators, have inherent limits to their voltage endurance. However, the alumina ceramics N-9H and N-999S, proudly produced by Nishimura Ceramics, boast a high insulation resistance that prevents insulation breakdown even at over 6000V with a thickness of just 0.3mm. Additionally, their volume resistivity maintains high efficiency not only at room temperature but also at elevated temperatures exceeding 100°C. In high-temperature processes, the resistance of the base material has its limits, making these ceramics suitable for environments where insulation breakdown must be withstood at high temperatures, and where a higher voltage, safer, and higher purity insulator is required. Unlike regular alumina ceramics, which may have particle structures influenced by sintering aids or voids, resulting in a less dense particle arrangement, this high insulation resistance alumina ceramic features an ultra-dense particle structure that maximizes the inherent properties of alumina ceramics.

CFRP is broadly categorized into two types: "PAN-based" and "pitch-based." Our company recommends "pitch-based" CFRP. Compared to PAN-based CFRP, pitch-based CFRP excels in tensile modulus (stiffness) and is particularly suitable for stiffness design applications. (PAN-based CFRP excels in tensile strength and is often used for strength design applications.) 【Heat】 In terms of heat resistance, there are special grades ranging from 80°C to a maximum of 250°C, with a coefficient of thermal expansion lower than that of ceramics and high thermal conductivity grades exceeding 100W. 【Vibration】 It has excellent vibration damping properties, and significant effects can be expected for forks used to transport heavy objects compared to metal. It exhibits outstanding performance in both self-weight deflection and load deflection when carrying workpieces. Because deflection can be minimized to the extreme, it is also possible to transport forks into narrow openings. 【Stiffness】 Due to the high tensile strength of PAN-based CFRP, it is often used in passenger aircraft, wind power generation, and automotive parts. Pitch-based CFRP can control the modulus of elasticity over a wide range, achieving high stiffness, and is widely used in satellite components, antennas, and robotic hands. We can design based on the customer's usage conditions. Please feel free to contact us first.

This is an introduction to overseas fine ceramics through our Chinese subsidiary. In addition to oxide-based materials such as alumina and zirconia, we have recently expanded our offerings to include non-oxide ceramics such as silicon carbide and silicon nitride. In particular, our general-purpose alumina is available in a wide range of grades, from high-purity grades suitable for semiconductor applications with a purity of over 99.5% to general-purpose grades aimed at cost reduction with a purity of 96% or lower. We can propose purity and grade options tailored to your specifications. We also handle a variety of zirconia with a wealth of experience. Regarding manufacturing methods, we employ a low-pressure injection method that minimizes mold costs, and we excel at creating three-dimensional structures that can only be reproduced through molding, making it especially suitable for cost reduction in medium to large lots. We also offer post-sintering polishing, and mirror finishes are possible. Additionally, due to high demand, we produce a significant amount of non-oxide hard materials such as silicon carbide and silicon nitride. Depending on the application and needs, we can propose various purity and grade options, so please feel free to inquire.

Oxide-bonded SiC (silicon carbide) has a thermal conductivity that is more than twice that of silicon carbide, and its strength is more than five times greater, maintaining stable strength from room temperature up to 1600°C. This is high-performance SiC, specifically silicon carbide refractory. - Recrystallized SiC "R-SiC" Recrystallized SiC is formed by sintering silicon carbide particles at temperatures above 2000°C. It has a purity of 99%, making it highly pure and particularly suitable for firing processes that are sensitive to impurities. Its maximum operating temperature is extremely high at 1650°C. - Silicon-impregnated SiC "Si-SiC" Silicon-impregnated SiC is a dense material that fills the pores between silicon carbide particles with silicon, reducing the porosity to nearly zero. It has extremely high thermal conductivity and strength, maintaining stable strength up to 1350°C. It is used in beams, rollers, nozzles, and other applications. As a refractory material under high temperatures, SiC (silicon carbide) maintains its strength sufficiently compared to concerns about strength degradation with conventional cordierite and alumina. It is also optimal for firing heavy objects and for environments that require high purity, such as electronic devices and electrode materials that are sensitive to impurities.
