Control of the temperature distribution of a mould and of cast or moulded parts produced
thereby |
(57) In order to control the temperature distribution of a permanent mould (and optionally
of the casting or moulding itself), one or more optical pyrometers scan the surface
areas of the mould and, if necessary, also the surface of a casting or moulding after
its removal from the mould, and operate a blowing system that will cool or heat those
areas so that desired temperatures are obtained according to the temperature readings
at each area.
