Plast-Control: Energy Usage Considerations when Purchasing Automation System for Blown Film Lines
Film manufactures are increasingly seeing themselves exposed to rising production costs. Huge increases in raw material prices, higher demands on quality from the end user, shorter delivery times and the compulsion of material saving has left little elbow room.
Leading edge companies have already invested in extrusion automation with some 3rd or 4th generation systems with high levels of automation being specified as a standard for new equipment. However there is a need for many older machines to be upgraded with modern automation systems to bring them up to date. Very efficient measures can be carried out at only a fraction of the cost of a new machine in order
to increase productivity and quality.
Utilization of high performance air rings with integrated profile control not only increases the output of the line by up to 50% but also the film tolerance is improved significantly plus a measurable reduction in scrap. In total the effectiveness of production is improved through, additional production capacity, improved film tolerances, order change times are minimized and raw material savings due to reduced gauge tolerances and shorter setup times…
