Case Study – Petrochemical Products stored outside Of 1000 stacked packs outside, no one shall leak. www.moellersgroup.com [email protected] Manufacturers of petrochemical materials are especially anxious regarding the load security of their products which tolerate no leakage. A new developed film feed welding device. Of 1000 stacked packs outside, no one shall leak. For perfect stacking, potentially disruptive edges on the film roof should be reduced to a minimum size. The roof tension is decisive for the formation of protruding film edges – the higher this tension the flatter the roof. Flat roofs however ensure secure stacking during transport and transfer in warehouses and outdoors – saving customers valuable time and prevents transport damage such as leaks. These two requirements are contradictory. Perfect tightness requires low stress on the weld-seam. A flat film roof and optimum appearance can be achieved by, among others, high weld-seam stress. Perfect load securing for outside-storage. Conclusion – safer storage outside at all locations – best possible protection for the product against external elements – perfect appearance for t

The tests were performed in a test series on the HSA-Vario coordinate machine of the Möllers Group Academy, at the customer’s premises and in collaboration with original film manufacturer. The machine settings were specifically examined, adjusted and optimized with regard to the three main influencing parameters pressure, time and temperature on the seal-seam strength. 2. Optimized process flow As part of the optimized process, quality is enhanced by active cooling immediately after the welding process - with simultaneous maximum welding tightness.
