The OKAY PLUS is equipped with a universal flask cradle i.e. with an easy movement of the lever it is possible to adjust the flask support and any sprue button in the flask will be easily centered with the crucible exit hole. This universal cradle is particularly suitable when using the technique of the free expansion withou metal casting rings. The sloping position of the crucible is very important because it allows the melted alloy to smoothly flow out of the crucible during spinning and it also ensures a complete and smooth flow of those alloys with a low specific weight. The highly efficient heating power output is capable of melting up to 100 grams chrome-cobalt-molybdenum. With 60-80 grams it is possible to cast two skeletons in one flask. For example 50 seconds are sufficient to melt 40 grams chrome-cobalt-molybdenum. The low power supply is 2,5 kW singlephase and it suits the small laboratories as well.
