Meaning
Volatile protective additives release metal-stabilizing vapors to prevent rust and oxidation on metal surfaces within an enclosed space. The use of a vci corrosion inhibitor protects steel mold cavities, cores, and ejector mechanisms from moisture damage during storage. These compounds sublimate from a carrier material and deposit a microscopic protective layer on the steel.
This treatment eliminates the need for heavy grease.
Protective Vapor
Atmospheric moisture reacts with tool steel to form rust, which ruins polished cavity finishes. When a tool is enclosed with a vci corrosion inhibitor, the protective molecules fill the air space and reach hard-to-access recesses. This coverage prevents oxidation in complex slide tracks and cooling channels.
The protection remains active as long as the enclosure is sealed.
Molding Recovery
Anti-rust grease must be cleaned off before a mold can return to production to avoid contaminating the plastic parts. Using a vci corrosion inhibitor reduces startup times because there is no grease to remove. Technicians simply open the mold and begin the heating cycle.
This transition reduces mold-setting times.
Application Formats
Packaging films and impregnated papers provide convenient ways to deliver these active molecules to the mold. Placing these items inside the sealed mold box protects the tool throughout the off-season. This method ensures the mold is ready for the next run.
