Extrusion International 3-2019

37 Extrusion International 3/2019 “When producing a perfect pipe not only our customers will be satisfied, but we will be too” Gerodur counts on inline millimeter wave technology from SIKORA for the measurement of plastic pipes Gerodur MPM Kunststoffverarbeitung GmbH & Co KG, a subsidiary of HakaGerodur AG (Gossau/ Switzerland), is a specialist in producing plastic products for piping systems and heating and sanitary. Since 2017, the company located in Neustadt/ Saxony, Germany has been using millimeter wave technology from SIKORA AG for the measurement of the wall thickness, diameter and sagging of plastic pipes during the extrusion process. The cooperation between the two companies is based on a future and also practice oriented solution for an automatic inline quality control in order to ensure the highest pipe quality and optimal processes Wherever reliability, wear resistance and corrosion resistance are required, plasticpipesarethebest choice.Wheth- er as piping systems for transporting water, sewage and gas, or for transfer- ring drinking water or for heating and sanitary facilities, quality requirements of the pipes are very high and deter- mined by standards. Since the founda- tion 26 years ago, Gerodur has been producing first-class plastic pipes with the focus on the highest product qual- ity, optimal processes and profitability. For the internationally operating man- ufacturer, the application of innovative measuring and control technology in extrusion lines is amatter of course. The first contact with SIKORA, manufac- turer of measuring and control devices from Bremen, was made several years ago. At that time, Gerodur was looking for measuring technology for smaller product dimensions in the area of heat- ing and sanitary facilities and found the MEASUREMENT TECHNOLOGY – CASE STUDY Gerodur produces, amongst others, piping systems with the highest precision
