centrifugal casting:
Single-layer:
The products we manufacture using centrifugal casting come in 37 graded sizes and lengths – according to the customers´ wishes. Besides the traditional areas of use, we recommend these products as suitable for use as semi-finished products for cylindrically shaped parts. The most common reason for choosing a centrifugally cast semi-finished product is the unavailability of the required material or the large savings in tooling the internal diameter. Thanks to its cleanliness and homogeneity, centrifugally cast tubing is the same standard as compression moulded materials.
Double-layer:
The use of centrifugal castings as an effective manufacturing technology for cylindrical shapes is enriched by the possibility of casting multi-layer materials. The result is a product with the properties of its external layer differing markedly from its inner layer. The divergent properties of these so-called ‘bi-metallic’ materials are used in special cases.
