＜Pharmaceutical dispenser nozzles＞
Pharmaceuticals are often expensive, so unnecessary dispensing can significantly increase costs.
Applicable to a wide variety of materials
We can make dispensing nozzles and picking nozzles from diamond, tempered alumina, zirconia, ruby, sapphire, tungsten carbide, stainless steel, vespel, and other materials best suited to your equipment and solvent. Ruby nozzles, in particular, are our original product.
Ceramics are turned into high-density materials through HIP (Hot Isostatic Pressing).
The HIP treatment densifies (shrinks) the material while maintaining its shape.

Dispensing nozzles and fluid injection nozzles often have a crawling problem when dispensing low viscosity fluids.
Orbray's dispensing nozzles can solve this problem by proposing a shape, material, and surface specification near the tip of the nozzle.
For example, during the production of precision parts or semiconductor-related parts, if a small amount of adhesive is used in a small area, the low viscosity of the fluid can cause crawling on the side of the nozzle tip. Our proprietary microfabrication technology allows us to improve the tip shape and surface roughness.

These dispensing nozzles are for inkjet printers, semiconductor manufacturing, and medical equipment. Monocrystalline ruby and sapphire have better surface roughness and wettability than polycrystalline materials, and therefore, the liquid flow is more stable. For example, a metal nozzle may not be able to apply the liquid straightly due to minute machining striations, scratches, or burrs.
In such cases, single-crystal ruby and sapphire, which have high hardness (Hv2000), have good straightness of hole processing by our processing technology, and by polishing the inside diameter, it is possible to dispense the coating material straight without any striations or burrs as with metal dispensing nozzles.

Picking nozzles are used for semiconductor products (resistors, IC chips, LEDs, sensors, etc.), inspection equipment, substrate mounting, precision parts, and microchip transfer.
In recent years, the miniaturization of device products has led to the miniaturization of mounted parts such as semiconductor chips and sensors. We produce suction and transfer nozzles and collets for various industries, and can also manufacture picking nozzles and collets for extremely small chips (chip size 0201).
We can also manufacture nozzles with a shape that meets the user's application by making full use of our precision machining capabilities.
For example, if there is a sensor in the center of the workpiece to be conveyed and the user does not want to touch it, we can manufacture picking nozzles(adsorption nozzles) with a concave shape only in the center to minimize the surface to be touched.
Pharmaceutical and reagent dispensing nozzles
Application: Discharge of medicines and reagents during production of medical products

*Please contact us if you require single crystal ruby or single crystal sapphire.
*Please contact us for the dimensions and shape you require.
These dispensing nozzles are used in the process of discharging drugs and reagents when producing medical products.
Since the components of drugs and reagents are not allowed to change, it is often impossible to use metal nozzles, which are prone to corrosion.
Therefore, Orbray can manufacture dispensing nozzles made of high-purity ceramics, ruby, or sapphire, monocrystalline materials that are highly resistant to chemicals.
The reagent is expensive and cannot be wasted, so it is important to apply the right amount at the right time, and by machining the tip finely, it is possible to apply the reagent as close as possible to the area to be dispensed.
Also, single crystals of ruby and sapphire can be seen inside by shining light through them, making it possible to check the state of inflow.
Problem Solving
Problem solving of dispensing nozzles （Precision nozzles)
Enabling high-precision control of dispensing volume
Unstable dispensing conditions caused by the viscosity of the fluid to be dispensed can lead to low productivity if the fluid cannot be dispensed precisely (in the right amount) to the targeted location. Our dispensing nozzles improve fluidity by devising fluid flow paths in the nozzle bore, which prevents clogging and bending of the fluid, thereby improving dispensing accuracy.
Our ceramic nozzles also have an extremely smooth fluid path surface, which improves fluidity, shortens tact time, and improves yield.
Prevents interference with a variety of workpieces in fine dispensing
When dispensing in a narrow area, the tip of the precision nozzle may come into contact with the workpiece, causing the fluid to stick or string outside of the targeted area. To solve such problems, we offer nozzles that are as close as possible to the application position by making the nozzle tip as sharp as possible and machining a clearance so that it does not contact the workpiece, enabling precise application even in narrow spaces.
Problem Solving of Picking nozzles (Collets)
Proposal of picking nozzles suited to the workpiece is possible
We can design an adsorbed surface that matches your workpiece. From the selection of material, we can propose a collet tip shape design suitable for a wide variety of workpieces.
Example,
With metal nozzles, the nozzle tip wears out or bends, preventing accurate application.
Wear-resistant measures can be taken using ruby, sapphire, and ceramic, which are resistant to wear
Do not want to touch the surface of the workpiece to be adsorbed.
The nozzle tip can be processed into a concave shape so that it does not touch the workpiece surface and can be applied to only a corner of the workpiece as much as possible.
Heat is generated during suction.
Proposal of Vespel, a heat-resistant resin, is possible.
Long life is realized with high wear-resistant material
For the problem of tip wear of picking collets, hard materials such as single-crystal ruby, reinforced alumina, and zirconia are used to achieve long life with excellent wear resistance.
In addition, the low wear of the tip allows workpiece positional accuracy to be maintained over a long period of time, contributing to overall productivity improvement.
Problem Solution Examples
Precision machining significantly improves productivity of LCD panels by controlling the amount and reproducibility of minute (liquid crystal) coating.
Our core technologies of "cutting, grinding, and polishing" are used in various fields such as semiconductors, industrial equipments, medical parts manufacturing, and laboratories. As the size of LCD panels increases, more precise control of coating volume is required, and our monocrystalline ruby nozzles, which enable stable and precise control of coating volume with long life, are useful in the field. Especially in the manufacturing process of LCD panels for flat-screen TVs and PCs, adhesives are applied to a wide range of areas with dispensing nozzles and needles. Orbray contributes to the improvement of dispensing accuracy through precision machining of nozzle shape, hole size, and bore diameter, as well as surface roughness to meet the customer's requirements.

Notes
*A two-pronged screw is a screw with two screw spirals. The distance that a screw with one helix (one-way screw) advances in one rotation is called the lead, but a two-way screw has twice the lead of a regular screw in the same one rotation, enabling quick mounting with fewer rotations.
There are differences in the mounting part depending on the equipment manufacturer and model. Generally, the two-joint screw type is the mainstream, but please confirm this when considering the product.
*What is a luer lock: A threaded, more pull-resistant type of fixture system that prevents fluid leakage in syringes and other medical devices.
