Positioning

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.

Features

• Produces no acid-mist inhibitory residues during treatment and does not corrode the substrate, thoroughly solving the common problems of 'blackening' and 'over-etching' of die-cast aluminum parts in conventional cleaning. Exposes a uniform, active pure aluminum layer, providing a highly activated clean base for subsequent passivation, anodizing, and spray coating, significantly improving adhesion and film uniformity.
