Retrofit solutions for blown film machinery
Increased Productivity through Modernization
In addition to supplying new blown film lines, Windmöller & Hölscher (W&H), Lengerich, Germany, also modernizes older W&H blown film machinery as well as other makes of blown film equipment. The focus of W&H’s retrofit programs with modern components is on improving output rates, film quality, plant availability and flexibility and reducing waste and material usage. Retrofit solutions offered for this purpose range from material supply to controlled gravimetric metering, plasticizing units, dies, sizing cages and haul-offs and also encompass the winder and the entire process automation concept. One important production factor, e.g. in order to increase the output rate of a blown film line, is optimum cooling of the film bubble. By retrofitting W&H’s modern Multicool air ring, output can be increased by up to 30 %, while film tolerances can be significantly improved at the same time.
