Process mechanic specialising in semi-finished products

As a process mechanic apprentice, you will learn how to work safely with plastics. In our extrusion department you will learn how plastic pipes and profiles in different sizes/dimensions, from 16 mm to 630 mm, are produced on the many different pipe lines (extrusion lines). The main task of the process mechanics is to set up the extrusion machines. This includes the selection of the right machines, the required material and the necessary tools. Only if no mistakes are made here will the finished tube meet the specifications of our international customers and can be delivered on the desired date. As a process mechanic, you are also responsible for ensuring the required quality.

During your training you will be taught these tasks step by step by experienced setters on the early shift. If you were to be taken on as an employee after completing your training, you would then work for us as a setter and be responsible for the various extrusion lines in shift operation.
