Caldera Heat Transfer Fluids ensure precise temperature control in die cast systems processing zinc, copper, aluminum, magnesium, lead, pewter and tin based alloys. The process involves injecting a molten metal under high pressure into a steel mold/die, which is in turn cooled by a heat transfer fluid running in cooling lines.
Controlling the temperature of a die casting die through the appropriate location of cooling lines is critical to performance and die life. Caldera Heat Transfer Fluids process the heat energy in the system and ensure that the die can be operated productively, resulting in the highest possible product quality. Their high temperature stability prevents thermal cracking and a resultant reduction in viscosity. Caldera Heat Transfer Fluids are also infused with anti-oxidative additives that prevent the formation of varnishes and deposits in the system.
