【OEM/Custom Made】No post-processing is performed; fine shapes can be achieved only through injection molding! It is also possible to manufacture fine needles with a tip diameter of several tens of micrometers, thinner than human hair.

★【Download the Catalog】Those who download will be entered into a lottery to win a novelty item (see image for reference)★ We have established "ultra-fine injection molding technology using plastic injection molding." We are able to create fine shapes that were said to be impossible with conventional molding, all through injection molding without any laser processing or post-processing. For example, we can produce fine needles with a tip diameter of several tens of microns, which is thinner than a human hair (80μm). 【Ultra-fine processing through injection molding】 ■ With advanced mold development technology using synchrotron X-rays, we can: - Mass-produce products with stable quality at low cost - Achieve surface precision superior to cutting or laser processing *For more details, please refer to the related links or feel free to contact us.
