Surface texturing applied on key components in the eco/bio industry or product and technology for surface texturing application


Client / Market

  • Friction reduction transportation field, machine lubrication field, Solar cell luminance efficiency improvement field, hospital’s anti-virus biofilm and selfcleaning field, display industry


Necessity of this Technology

  • Relying on the shape and material of components processed using existing technology has limits regarding friction reduction and pro-/anti-cell increase technology, and to create a surface with additional function, smart surface texturing technology with surface pattern with the size up to several hundred microns needs to be applied.
  • Relying on the shape and material of existing components has limits regarding friction reduction and pro-/anti-cell increase technology-this technology can be considered very original as it is an eco-friendly process-based high-precision machining technology that replaces existing chemical etching or MEMS method.
  • Need friction reduction, pro-cell functional effect realization, and various converged machining


Technical Differentiation

  • Using a component with fine patterns created on the surface, a functional component can be created. Obtainable effects include friction reduction, cell and virus-related characteristics improvement, and enhancement of optical function.
  • Analyzing and simulating the smart textured surface in nature require pattern shape measuring technology, computer simulation technology to copy the pattern and estimate the function of the pattern, high-precision machining and control technology to process pattern, and chemical process for post-processing of surface; its technological ripple effect throughout the field of engineering is great.
  • Based on realization of the eco-friendly method, this technology grants detailed surface texturing using a method other than chemical treatment-partially applied in the industry, and in particular, the technology goes beyond the limitations of material as it can even be applied on metal surface.
  • This technology includes technologies for various ripple effects regarding surface texturing module, applicable eco/bio-related products, and machine for module application.
  • As machining realizes uniform function, it is favorable for creating consistency in function between products.


Excellence of Technology

  • For dimple and riblet machining, lubrication friction and air/fluid friction is reduced by up to 8 to 10%, which has been proven with theory and experiment.
  • High-precision machining method for surface texturing can be directly applied on hard material.
  • Surface texturing shape research, machining process development and shape measurement/function evaluation technology is a leading advanced technology growing globally.
  • Has 3 international patents and 34 other patents Received multiple awards including Award Certificate of Director of Patent and Trademark Office (No. 7487, 2009) and Order of Science and Technological Merit (Jinbo Medal) (No. 94, 2011)
