Nanshin Micropipe Technology

Nanshin Micropipe Technology

Micropipe is a surprisingly tiny and extremely precise metal pipe, which is manufactured by electroforming.

Electroforming process is operated by these three basic steps;

  • A mandrel is put into plating bath and coated with single or multiple materials.
  • The mandrel is released from the material once it has gained enough plating thickness.
  • The separated plating layer is cut into any desired length.

Micropipe can reach the level that machining or swaging pipes would not!
