Micro hole processing is possible up to an inner diameter of Φ15μm! We offer a wide range of custom solutions, including high aspect ratio precision nozzles and irregular nozzles! We can accommodate from single units to mass production!
Orbray Co., Ltd. provides precision nozzles and needles made from appropriate materials tailored to specifications, applications, and prices. In particular, our single crystal ruby nozzles are our unique products, boasting a smooth inner surface. We can process fine holes with an inner diameter of up to Φ15 microns. Additionally, by controlling the machining accuracy at the micron level, we minimize variations in coaxiality and straightness to the utmost limit. Our ceramic materials undergo HIP treatment, resulting in uniform, high-quality materials with extremely few defects such as pores. HIP-treated materials can achieve an inner diameter surface roughness of Ra 0.01 microns. We also offer extensive custom options for precision nozzles and irregular nozzles with high aspect ratios for both inner and outer diameters. We cater to a wide range of needs, from single units to mass production. ■ Materials Used - Alumina - Reinforced Alumina - Zirconia - Ruby - Sapphire - Carbide - SUS - Bespel, etc.

■Dispenser Nozzle, Liquid Injection Nozzle, Special Nozzle When dispensing low-viscosity liquids, dispenser nozzles and liquid injection nozzles often encounter issues with liquid climbing. However, Orbray's nozzles offer solutions through their design, materials, and surface specifications near the tip to address these problems. Additionally, we propose special types of nozzles, including multi-hole structures with 2 or 3 holes and single-hole 12-channel assemblies, primarily designed with ceramic materials.

■Suction nozzles, suction collets, transport tools We handle key parts such as suction nozzles, suction collets, and work positioning parts that are essential for achieving stable production of manufacturing equipment for semiconductors, industrial machinery, and medical devices. At Orbray, we respond to customer needs by using a variety of materials including reinforced alumina, zirconia, alumina, silicon nitride, aluminum nitride, sapphire, ruby, and cemented carbide, all of which offer wear resistance and high precision.

■Winding Nozzle It excels in wear resistance, and the ruby applied at the tip has low friction resistance and is processed into a smooth R shape from the inner diameter of the nozzle to the tip, allowing for smooth movement during winding operations without damaging the wire. Additionally, the ruby at the tip is highly durable due to its hardness, second only to diamond, making it suitable for continuous use. The winding nozzle is designed and manufactured to match the specified shapes of the R shape and surface roughness at both ends of the nozzle entrance and exit as per customer requirements.
