Pipe processing
~ drawing

パイプ圧延加工

Pipes are manufactured using a special pipe machine using precision piping technology not available from other companies. Pipes are made small in diameter by drawing.

Pipe linearization

We use our proprietary technology to straighten the pipe.

Pipe bore polishing

Pipe bore polishing

This eliminates unevenness on the inner surface of the pipe and improves the liquid run-out. Finish to a surface roughness Ra0 of.05.
It is possible to develop in-house equipment and adjust the surface roughness with an inner diameter tolerance of ±0.02 or less.

Nozzle tip can be narrowed down. The upper pipe is long tapered. The lower pipe is PTFE coated.

Internal diameter polishing

Internal diameter polishing

As the skin of the narrowed internal radius will be rough, we will polish it with an internal radius polishing machine.

» Inner diameter polishing

Pipe inner surface roughness inspection

パイプ内面粗さ検査

Inner surface roughness can be measured with a proprietary Non-destructive inner-surface roughness inspector for small-diameter pipes device (Arasameal).

Needle tip processing

針先加工

Needle tip machining is performed with a dedicated cutting machine or a proprietary cutting robot.

» Nozzle/needle tip machining

Junction

接合

Laser processing is performed from various angles by tilting or rotating the nozzle. It is fixed by laser welding, adhesion, and brazing.

» Laser welding

Bending

曲げ加工

Secure the flow path by suppressing pipe flatness due to bending.
The bending radius may be applicable depending on the outside diameter and wall thickness of the nozzle.

» Option additional work

Buffing

バフ仕上げ

If there is a concern about liquid leakage at the point of connection with the partner’s components, the machining spot can be removed.
Also, the appearance of the nozzle product is finished to the specified surface roughness.

Surface treatment

Surface treatment

Possible to introduce water-repellent coating to control the amount of liquid to be applied, creeping up, and liquid run out. FC180 thin-film fluorine coatings are available on the internal and external diameters.
The fluorine coated state of non-contact roughness measurement and transparency can be inspected by a high-precision measuring instrument.
