„Chain reactions do not only take place in chemical bonds.” The single production steps could be described as chain reactions as well. Every step from drawing board to the finished product is only a small wheel in a huge machinery. The casting pretty much constitutes the centre of the production process. If the drawings were not made precisely enough by the customer or the mould construction team did not draw and mill accurate to a hundredth, the preparation of the production process was not planned exactly… well, then it is up to the casting team to react in time.
Hermann Ranftl stayed at asma after his apprenticeship to become a plastic shaper and has been working as a skilled worker at the casting team for two years now. “Over the years, I have got to know many different machines and various materials. I am fond of change and variation and if the worst comes to the worst, I can work anywhere,” Hermann Ranftl explains and adds, “I am happy to help my colleagues in word and deeds”.
Around 350 tons of polyurethane elastomers are processed at asma each year in various compositions. Every casting process has a special sequence. Casting by hand or with the help of a machine – demoulding with compressed air – subsequently, the parts are put in the annealing oven to postcure. Hermann Ranftl describes the special properties of Polyurethane as follows, “Every material has its own characteristics and reacts differently. Depending on the requirements, the formulations are mixed from very soft to extremely hard. Very often, this is can be quite a huge challenge”. Hermann Ranftl is specialized in the coating of various rolls and wheels for the application in elevators and lift systems.
