- mold tubes made of copper or a copper alloy are usually cold drawn to a Solidification, which gives the mold tube the required strength gives.
- the mold tube is provided in the mold cavity with a casting cone and is provided on the outside with a smooth wall or with smooth walls.
- the mold cavity is in many cases with electroplated coatings made of chrome and nickel.

- the stability of a mold tube is still determined by his ability to withstand the mechanical stresses to withstand casting.
- the mold according to the invention has the freedom to meet the requirements in terms of the heat dissipation and the stability of the mold cavity forming inner body to optimize independently by choosing appropriate Materials for the coating carrier on the one hand and the coating on the other hand.
- the coating carrier can be designed so that it provides a high mechanical strength of the inner body and thus ensures the desired stability of the inner body, while the coating in terms of thermal properties and the Thickness suitable can be chosen to heat dissipation of the inner body to optimize.
- a coating carrier made of a material with increased mechanical Strength is made, may have a reduced wall thickness and therefore allow an increase in the thermal output of the mold.

- the coating carrier and for the coating are the same or even higher heat outputs than the classic, achievable in the prior art mold, even if the thermal conductivity of the coating carrier is lower than the thermal conductivity of Coating.
- the decisive for the heat transfer wall thickness, in particular of the coating carrier, can be made relatively thin.
- the coating carrier on the mold cavity turned away side be provided with cooling fins.
- the cooling parameter may be a distance between the cooling fins of, for example 5 - 8 mm can be selected.
- the wall thickness of the coating carrier can in such constructions between the cooling fins 2 - 10 mm, preferably 5 - 8 mm, amount. A coating carrier with such thin wall thicknesses guaranteed together with a copper coating of, for example, 3 mm a high heat output.
- Coating carrier for Molds with a polygonal mold cavity cross-section for example be composed of several flat or curved plates, respectively form one of the mold cavity bounding side walls of the mold.
- inventive mold With optimal material selection of the coating carrier can in comparison to known molds with a identical stirrer, an increased stirring power can be achieved or to achieve the same stirring effect a weaker-conductor stirrer can be used.
- the inventive mold Because of the use of aluminum or an aluminum alloy for the Coating carrier is the inventive mold relatively easy in comparison to a corresponding mold of copper or a copper alloy. Because of the lower weight can be the Kokillenoszillation necessary in the casting operation in the inventive mold - in comparison with a corresponding Mold made of copper or a copper alloy - carried out with simplified means become.
