Abstract
A method is provided of producing a housing with two layers. The method includes casting an inner casting formed as an inner layer, and then casting an outer casting. The inner casting is used as a wall and the outer casting is formed as an outer layer. The inner layer is made of a more heat resistant material than the outer layer. Hooked formations are fitted on the inner casting in order to improve an integral bonding to the outer layer.
