Slpformer or extruder?

If you are planning to make small hollow-core and other products on the same bed, you need a slipformer for its versatility. Especially in a small plant, slipforming would be the most viable choice. In a larger factory, it can be more economical to make the hollow-core slabs, at least the thicker ones, with an extruder and the other products with a slipformer. The maintenance costs for a slipformer are lower than for an extruder, but then again an extruded slab is 10 percent lighter than a slab of the same thickness made by slipforming. Naturally, the heavier slipformed slab requires more concrete and occasionally one or two more strands to achieve the same span as with an extruded slab.

You may well want to think about acquiring both a slipformer and an extruder, to combine the advantages of both.
