About Power Micro International Co.

 Professionally engaged in metal processing, polishing, and surface modification technology, we are an industry-leading manufacturer known for our innovative highlights.

Since the introduction of sandblasting equipment in 2013, Lijingwei International, a professional metal processing manufacturer, has been dedicated to assisting customers in enhancing production quality and prolonging tool life. The company serves a variety of industries, including precision molds, semiconductor components, medical parts, optical molds, lithium battery tools, and carbon fiber molds.


In production environments where lubricants or release agents cannot be utilized, tools frequently adhere to materials such as tin, copper, aluminum, and plastic. This adhesion results in increased tool wear and higher defect rates.

The company employs micro-particle surface modification technology to effectively reduce the coefficient of friction between materials and metals, minimize adhesion, and significantly extend the service life of tools.



We adhere to the concept of "developing new possibilities, creating new demands," and through industry-leading sensitivity and unique core technology and equipment of new processing methods, we are based in Taiwan and serve the world.




Technical Advantages


 Our Advantage Ⅰ
Unique Mirror Jet Polishing Core Technology

As a manufacturer specializing in metal polishing, we utilize patented equipment that employs flexible diamond rubber high-pressure jet spraying. This technology enables sliding friction polishing on metal surfaces, resulting in uniform and rapid polishing effects.
