Shihuiming
Focuses on deep activation of mold release agents, silica ash (black ash), and natural oxide films on die-cast and extruded aluminum surfaces. Removes all types of oil stains and natural oxide layers generated during machining, stamping, and storage of aluminum and aluminum alloy parts in a single step.

Uses a chromium-free environmentally friendly formula to construct a uniform and dense conversion film on the aluminum surface through chemical reaction. This passivation film significantly improves the salt-spray resistance and rust prevention level of aluminum alloys, while serving as an excellent base for organic coatings, enhancing spray coating adhesion by one grade. Suitable for functional protection of aluminum profiles, die-cast parts, and aluminum castings in demanding environments.

Includes chemical polishing and electrolytic polishing process solutions that flatten microscopic peaks and valleys on the aluminum surface through selective dissolution, achieving a smooth, refined, and lustrous appearance. After polishing, aluminum parts have significantly improved reflectivity and smooth tactile feel, with fine burrs eliminated.
