A distinct differentiation is made between a slip former and an extruder as the production machine. Aside from these, there are also simple concrete distributors or auger dispensers which are used for the production of basic floor slabs, rail road ties, etc. on specially designed form beds.
Different products, as mentioned in the opening paragraph, can be made with the slip former, whereas the extruder lends itself only for the production of hollow core slabs.

The slip former consists of two components, the automatic feed unit and the so-called machinery insert. Both components are united for production. Due to its design features, individual machinery modules can be dismantled completely in a few manual steps. Different concrete elements can be made by exchanging the machinery insert. Different heights of the same concrete product, such as hollow core slabs, girders, lintels, can be produced by adjusting the machinery insert and exchanging some components, such as the tube sets for hollow core slabs.
