到证明，长期保护的特性令人印象深刻。极高的质量和长期测 试以及特殊的测试程序证实了其非凡的弹性。这种新一代产品 具有高弹性和一体化自粘边缘，是各种应用的完美解决方案。 它可以实现更高的能源效率和更高的生活舒适度，” 直观的操作-综合检测系统 SML软件应用工程师开发的SMILE控制系统是两条生产 线的核心要素。这使得生产线的操作非常直观，可以根据各自 的生产过程和相关功能进行定制。SML产品经理Johannes Danter指出：“综合检测系统和我们的数据管理工具BitWise， 确保对两套设施的整个工艺链进行全面监控。每个产品的生产 参数都可以完全追踪”。对于Dörken而言，要遵守最严格的质 量标准，特别是长期让产品满足市场的需求，这是一个巨大的 帮助。 现代化显著提高了效率 来自SML的两条生产线由于其较低的原材料消耗，使得 效率大幅提高。与以前可用的设施和工艺技术相比，新一代高 透气屋顶和立面膜材的生产只需一个生产步骤。此外，该生产 线的生产速度相对较高，可达120米/分钟。在节省大量时间的 同时，生产过程中产生的废料也减少到了最低限度。 SML的两条新生产线取代了现有的几家工厂，为Dörken 提供了生产创新膜材的机会。他们强调：Dörken的目标是尽 可能经济地制造、高效利用资源，并通过进一步的开发工作大 大改善产品性能。 W hen it comes to membranes for the construction industry, Dörken is European market leader. In autumn 2022, the company opened a new production site in Hagen-Vorhalle in North Rhine-Westphalia, where the two coextrusion coating and laminating lines from SML are now up and running. The tailor- made plants are setting new standards in terms of functionality, quality monitoring and the degree of automation involved. Previous product development at SML’s Technology Center "The remarkable thing about this project is that Dörken did not carry out substantial parts of the product development process at its own plants, but on an industrial scale FlexPack ® line loca- ted in our Technology Center," Dirk Beckendorff, Area Sales Ma- nager at SML, explains. The product development process at SML took several years: Among other things, it included basic tri- als with the SML DoubleCoat process, test series with the most important products of Dörken’s portfolio and several test runs for the development and sampling of new roofing membranes. Since it was possible to certify a number of products even before the lines were commissioned at Dörken, the over-all product de- velopment process was accelerated quite significantly. “It was important for us to benefit from the opportunity offered us by SML. In addition to confirming the known recipes and processes, we were able to use SML’s pilot plant for our innovations at a very early stage. In principle, we have actively integrated SML’s plant into our Stage Gate process,” Christian Harste, CTO at Dörken, clarifies. Immediately after the installation of the two lines, Dörken was able to start regular production. 63 Extrusion Asia Edition 1/2023 New standards for products One of the two multi-purpose coating and laminating lines at Dörken is equipped with SML's patented DoubleCoat techno- logy. This technology enables a combined adhesive and extru- sion coating process for the production of ultra-thin and highly breathable laminates. It allows the manufacturing of a wide va- riety of technical composites for the construction industry, such as vapor barriers or waterproofing membranes. The second production line is a combined line with two inte- grated adhesive roll coaters for the manufacturing of highly breathable roofing and facade membranes in one production step. The thickness of the TPU membranes can be considerably reduc- ed, compared to conventional products available on the market. Thanks to the innovative system technology, significantly im- proved water vapor permeability values can be achieved, with, at the same time, excellent product properties with regard to longevity. “Our new underlay membranes are impressive with their proven durability and thus long-term protection. Extreme quality and long-term tests as well as special test procedures confirm their extraordinary resilience. With a high elasticity and integrated self-adhesive edges, this new generation of products is the perfect solution for a wide variety of applications. It en- ables a higher energy efficiency and a raised living comfort,” Dörken-CTO, Christian Harste, states. Intuitive operation – integrated inspection systems A central element in both production lines is the SMILE control system developed by SML software application engineers. This enables the highly intuitive operation of the lines, tailored to the respective production process and the associated functionalities. "Integrated inspection systems and our data management tool, BitWise, ensure the comprehensive monitoring of the entire pro- cess chain at both plants. The production parameters of each product can be completely traced," SML product manager, Johannes Danter, points out. This is an enormous help to Dörken when complying with the strictest quality standards, especially regarding the long-term product guarantees the market de- mands. Modernisation with a significant increase in efficiency The two production lines from SML allow a massive increase in efficiency because of their lower raw material consumption. Compared to the plant and process technology previously avail- able, the production of the new generation of highly breathable roofing and facade membranes takes place in just a single pro- duction step. In addition, the lines operate at a comparatively high production speed of up to 120 m/min. Along with conside- rable time savings, the waste generated during production is re- duced to a minimum. The two new lines from SML replace several existing plants and give Dörken the opportunity to produce innovative membranes. They emphasize Dörken’s claim to manufacture as economically and resource-efficiently as possible – with greatly improved prod- uct properties achieved through further development work. ➠ SML Maschinengesellschaft mbH Gewerbepark Ost 32, 4846 Redlham, Austria www.sml.at
