Features of very high-precision fine pipes

  Very high-precision fine pipes SUS pipes Copper alloy pipes Nanshin's technology
Precision ◎
±0.003 or less as standard
△
About ±0.01
△
About ±0.01
A level of precision not possible using machine tools and other methods can be controlled with mass production.
Adjusting hardness ◎
Can be adjusted
×
Cannot be adjusted
×
Cannot be adjusted
It can be made harder than hardened metals or as soft as brass.
Internal roughness ◎
Ra0.1 or less
×
Occurrence of joints and lines. Needs to be polished.
△
Ra0.1 or more
Can be made with a very smooth inner surface and no tool marks or seams (joints).
Multilayer technology ◎
The inner surface can be evenly plated.
×
The inner surface is difficult to plate evenly.
△
Difficult to clad (laminate) or handle flexibly.
This is a diverse multilayer technology made possible by electroforming. For example, the inner surface can be thickly plated with gold (2 μm or more). Depending on the material, electroforming can even be performed on insulating materials.
Wall thickness
(Sheet thickness)
◎
Flexible control is possible.
×
Difficult to adjust above JIS standards.
×
Difficult to adjust.
We have managed to control the wall thickness from 0.01 mm to more than 3 mm by taking advantage of electroforming and adjusting the voltage and current.
Aspect ratio ◎
A long and even fine pipe is possible.
×
Extremely thick and thin walls are not possible.
△
Difficult to maintain precision of thick and thin walls.
As opposed to machine-tool processing, bending and semi-seamless pipes, pipes that exceed the normal limits of aspect ratio can be made.

What are very high-precision fine pipes?

As indicated by their name, they are very precise, very small metal pipes.
They have several small dimensions such as their outer diameter, inner diameter, wall thickness (sheet thickness), etc., but this is a surprising technology that achieves precisions that are not possible with machine-tool processing and drawing processes.
Also, it is not just that they are small, the ability to control the wall thickness (sheet thickness) is also a feature.

Basic specifications

Material composition Nickel, copper, platinum, etc.
Thin film materials (multilayer electroforming) Nickel, copper, gold, platinum, etc.
Outer diameter 0.06 ~ 10.00mm
Inner diameter 0.04 ~ 9.00mm
Total length 0.5 ~ 500mm
Wall thickness(Sheet thickness) 0.010 ~ 3.0mm
Outer diameter precision ±0.003 mm as standard. ※ ±0.0005 mm is possible depending on the size.
Inner diameter precision ±0.003 mm as standard. ※ ±0.00025 mm is possible depending on the size.
Hardness (for nickel products) Hv.200~700 ※Can be controlled in accordance with customer's request.
Pipe internal roughness
Ra:0.1 or less as standard. ※ About Ra:0.03 is possible depending on the size.
  • In-house integrated production: We have our own electroforming plant and an integrated production system from production of materials to shipping.
  • Prototype development to mass production: We can handle orders from a single prototype to mass production exceeding 100,000 units.
  • High-variety capability: We accept orders from customers and separate them according to their specifications at the 0.001 mm level and according to their tolerance. We think of high-variety orders as being a matter of course.
  • Conforming to ISO: We deliver reassurance with monozukuri and a management system conforming to ISO9001 and ISO14001.
