SUS Pipes Copper Alloy Pipes Nanshin’s Technology
Accuracy ◎Standard of ± 0.003 or less △About ± 0.01 △About ± 0.01 It is possible to control accuracy in mass production to a degree that cannot be achieved through machining or other construction methods.
Hardness adjustment ◎Adjustable ×Not adjustable ×Not adjustable It can be made harder than quench-hardened material or as soft as brass material.
Inner surface roughness ◎Ra of 0.1 or less ×Seams and wrinkles occur. Polishing required △About ± 0.01 It can be manufactured with a very smooth inner surface without any scratches or seams.
Multi-layer technology ◎Uniform plating on the inner surface is possible ×Difficult to achieve uniform plating on the inner surface △Flexibility difficult to achieve for cladding (laminating) support This versatile multi-layer technology is made possible by electroforming technology. For example, it is possible to thicken the inner surface with gold plating (2μm or more). Depending on the material, insulating material can be electroformed as well.
Wall thickness
(plate thickness)
◎Supports flexible control ×Difficult in making adjustments to meet or exceed JIS standards ×Difficult to adjust Through the unique current and voltage adjustments of electroforming technology, we have achieved flexible wall thickness control that enables adjustments of between 0.01mm and 3mm or more.
Aspect ratio ◎Fine and uniform long pipes are possible ×Extremely thick and thin walls are not supported △Difficult to maintain accuracy in thick and thin walls Unlike machining, bending, and semi-seamless pipes, it is possible to manufacture pipes that exceed the processing limiting value generally known as the aspect ratio.

In-house integrated production

We have developed an electroforming plant in-house and handle the entire manufacturing process, from material production to shipping.

Full support from trial development to mass production

We handle everything from single trial orders to mass production of over 100,000 pieces.

Support for a wide variety of products

We accept customer specifications by classifying them in 0.001mm increments or based on differences in tolerance.
We consider this abundance of variety the natural state of things.

ISO-compliant

We provide peace of mind with manufacturing and management systems that comply with ISO 9001/ISO 14001.
