The majority of packaging in the bottle and container industry is mono-layer in design, i.e. made from a single layer of material. For this purpose, we usually provide so-called “spider-type” heads, whose technical design ensures uniform material distribution even with varying throughput requirements and the shortest material and color changeover periods. Our spider-type heads are used around the world. A wide range of plastic raw materials are processed using this style of extrusion heads. As with all of our products, high performance, user friendliness, and low maintenance are at the forefront of our planning and development objectives. Our product portfolio offers numerous head sizes with parison diameters from 25 mm to 650 mm as well as multiple extrusion heads with up to 24 parisons for multi cavity molding machines.
The special requirements placed on the product characteristics demand particular expertise in extrusion technologies and materials, including the extrusion head. Examples of these product characteristics are:
Refi ned surface fi nish for a high-quality appearance or as pre-treatment for special printing techniques Material cost savings due to the application of expensive pigments in a thin outer layer Material cost savings due to the integration of recycled resin or the integration of a material mixed with calcium carbonate (chalk) in a separate layer Utilization of bio-plastics in a separate layer Barrier properties to protect the product against oxidation or to protect the environment against the migration of aggressive products Insertion of a conductive layer to prevent electrostatic discharges if the container is intended for explosive products
We offer proven solutions with multi-layer extrusion heads for up to seven material layers for every area of application. Needless to say, all extrusion heads are also available for multi cavity molding systems. For many applications it is also possible to integrate a transparent section in the layer structure, without impairing the product properties at this specific point.
