No. The primary function of die-casting release agents is to assist in demolding during die casting. Under normal circumstances, the requirements for release agents include
good lubrication,
excellent thermal stability,
easy demolding, and
simple cleaning. If molten metal fills the mold smoothly without issues like cold shuts or forming difficulties, the thermal retention of the release agent does not need to be excessively high. However, for molten metals with poor filling or low fluidity, improving the release agent’s thermal retention to enhance metal fluidity is actually beneficial. In summary, it is essential to select a die-casting release agent that suits specific needs.
