1.General Description
Read thismanualcarefullybeforeoperationtopreventdamageofthe
machine orpersonalinjuries.
STM-HTserieshightemperatureoil heaterareusedtoheatup the mouldand
maintaintemperature,althoughtheycanbeused inothersimilarapplications.
Hightemperatureoil fromthe mouldisreturned tothecoolingtankand cooledby
indirect cooling. It isthen pressurised bythe high-pressurepump,sent tothe
heatingtankandfinallytothe mouldwithaconstant temperature.Withour
optimised design, Itcanreachamaximumof300andthe HANYOUNG
temperaturecontrollercan maintainanaccuracyof 1.
