Release Agents for Die Casting: Function and Benefits

Release agents for die casting are essential products in metal casting processes—particularly for aluminum, zinc, and magnesium—to ensure both the quality of the part and the durability of the mold. Their main function is to create a barrier between the molten metal and the mold surface, preventing adhesion and facilitating the extraction of the casting.

Key Features

High-temperature resistance:
They must withstand contact with molten metals at temperatures above 600 °C.

Lubrication:
They reduce mold wear and improve the surface finish of the part.

Mold protection:
They prevent corrosion and the buildup of residues.

Types of Release Agents

Water-based:
More environmentally friendly and safer, reducing emissions and fire risks.

Solvent-based:
Used in specific applications where rapid evaporation is required.

Concentrated or ready-to-use products:
Chosen based on production needs and mold characteristics.

Operational Benefits

• Improved casting quality.
• Reduced cycle times thanks to quick and clean release.
• Extended mold life, with a consequent reduction in maintenance costs.

The choice of the correct release agent depends on factors such as alloy type, mold complexity, and operating conditions. Uniform and controlled application is essential to achieve optimal results.
