eyeless needle hole
In 1976, five years after the start of research, we became the first in the world to produce eyeless needles using laser beam drilling technology. The bonding technique, whereby the suture thread is inserted and bonded to the needle hole, makes damage to the tissues less likely and enables exceptionally smooth penetration.
Metal Material Technology

Standard stainless steel

MANI hard -fiber stainless steel
We pursued opposing qualities such as toughness and hardness to create our original material, MANI hard-fiber stainless steel. By adding our original "seisen" process to 18-8 stainless steel, we were able to develop flexible and corrosion-resistant needles.
Testing and Evaluation Technology

We develop testing and evaluation machines in addition to forming machines in order to draw maximum benefit from the material characteristics and original technologies arising out of our accumulated research results. With this original testing and evaluation technology, we pursue "the best quality in the world".
