Product Type

HIP-processed ceramic nozzles and needles

• High density achieved with HIP processing means less chance of chipping
• Use of injection molding means no variation of inner surface shape
• Shape can be produced to meet the needs of the customer
• Excellent cost performance
• High quality and long service life
• Disposer type also available

Single crystal ruby nozzles and needles

• Low resistance due to single crystal
• Internal surface mirror polishing makes the flow of coating solution smooth and less likely to clog
• Diameter of the opening ranges from φ30 μm down to φ15 μm (for semiconductive fine hole nozzle)
• Even and stable application, high reliability, and long service life

All nozzles are compatible with double threaded screw and luer lock.

Problem solving

Problem solving of dispenser nozzles

Control of application amount

Application accuracy can be improved by devising the liquid flow path in the nozzle and the pressure control according to the purpose.
The fluid passage of the ceramic nozzle has a very smooth surface, which can reduce the loss of discharge pressure.

Interference in precision application

In cases where a minute coating is being applied to a very narrow area, the workpiece and precision nozzle may come in contact.
At Orbray, we sharpen the tip of the nozzle as much as possible for a precise application that doesn't leave residual material on the tip.

Problem Solving of Pick-up Collet (Nozzle)

We can design a pick-up surface (pick-up collet) suited for your work.
We can propose the design of a collet tip shape according to a wide variety of workpieces, starting from the selection of materials.

Long service life thanks to highly wear-resistant material

To address the problem of tip wear of the pick-up collet, wear-resistant hard materials such as single crystal ruby, reinforced alumina, and zirconia are used to improve service life.
With less wear on the tip, workpiece position accuracy can also be maintained for a long period of time, contributing to overall productivity improvement.

Precision processing significantly improves the productivity of liquid crystal panels through control and repeatability of minute application amounts.

Our long-life nozzles are adopted as a liquid material discharge device requiring highly accurate coating amount control. Particularly, with the expansion of panel size, further improvements in accuracy are required, surface abrasion technology of the nozzle tip and precision machining of the inner and outer diameters are utilized, enabling stable and accurate control of coating amount, single crystal ruby Nozzles are useful in the field. In the manufacturing process of LCD panels for flat-screen TVs and PCs, the adhesive is applied to a wide range of locations with a precision nozzle and needle. The failure of a single coating makes the whole unusable, so application control directly affects production yield.
Orbray contributes to the improvement of application accuracy through precise processing of nozzle shape, hole diameter size, inner diameter shape, and surface roughness based on customer's request.
