Due to the continuously increasing level of demand, the plastics industry has developed into a dynamic, highly-specialized industry. The extrusion of blown or cast films places equally high requirements on production systems as on coating or lamination processes. Constant material thicknesses, independent of the number of layers or web widths, are the precondition for perfect product properties. As a specialist for system solutions and automation technology on moving webs, Erhardt+Leimer can support its customers from the plastics industry in meeting these requirements with innovative, efficient systems.
Coatings and the lamination of highly-complex products in the converting industry involve the smallest coatings and tension-controlled material combinations. Only when everything is perfectly matched – from the substrate through control to quality assurance – is it possible to create state of the art product properties.
Besides high-accuracy production machines, multi-layer extrusion, as well as coating and laminating processes require checking. For this, Erhardt+Leimer can offer systems for surface analysis, which detect the smallest defects immediately. Our systems can even detect deviations in the coating application using a measurement accuracy down to the µm range and, if so required, can leave no area unmonitored. In lamination processes, our web tension load cells with networkable measuring and control amplifiers can ensure that the web tension in the converting industry is always sensitively controlled, depending on the material. Thus extraordinary combinations can fulfil their tasks over a long period of time.
