The SPB melt filter from Star- linger, on the other hand, achieves a high melt throughput with excellent cleaning capacity even in the case of more heavily contaminated input materi- al. This way, a stable production process and high degree of efficiency are ensur- ed. Thanks to the hydraulic backflushing function of the filter, the respective filter screen is backflushed and thus cleaned when a defined degree of contamination is reached. The backflush cycles are rela- tively short due to the high pressure build-up in the filter, and the extrusion process is not interrupted – an important criterion that saves material and time. Depending on the degree of contamina- tion of the melt, the filter can achieve throughput rates of up to 720 kg/hour and allows for 50% and more of recyc- late in tape production. Know-how for a closed packaging cycle: “For optimum recyclate quality, our division Starlinger recycling techno- logy offers recycling plants that are tailo- red to the specific needs of bag manu- facturers,” adds Hermann Adrigan. “In principle, we at Starlinger combine the know-how and technology for “circular packaging” under one roof: From the manufacturing process and the packag- ing recycling process to reusing the recy- clate for the same product. And our cus- tomers benefit from this. With our equipment, it is a lot easier for packag- ➠ Guill Tool & Engineering Bill Conley: bconley@guill.com , www.guill.com Touch系统相结合，可消除聚 合物泄漏。 Guill还提供独特的 螺旋流量分配系统。 所有Guill工具都是通过使 用计算流体动力学（CFD）程 序对流动通道进行严格的计算 机模拟生成的，从而优化均匀 流动，而且没有焊接线。 Extrusion Tooling n Guill introduces the latest generation of its Series 800, the 2-to-6 layer extru- sion tooling designed to produce the highest quality, highest material-efficient 1/8” to 6” OD tubing for automotive, medical, appliance and industrial appli- cations. The redesigned Series 800 prod- uces flawlessly smooth extrusion and lay- er definition of Fluropolymer and other materials for all multi-layer, multi-lumen medical tubing, as well as fuel line con- structions, multi-layer PEX pipe and drip irrigation applications, among others. The Guill design further allows thin layer combinations of polymers and adhesives to .02mm or less. n Guill推出最新一代800系列产品， 这是一种2至6层挤压模具，旨在为汽 车、医疗、家电和工业应用生产高品 质、高材料效率的1/8至6英寸外径管 材。 经过重新设计的800系列可针对任 何多层、多腔医用管路以及燃料管路结 构、多层PEX管道和滴灌应用等生产完 美平滑挤压及具有层定义的氟聚合物和 其他材料。 Guill设计进一步允许薄层 （0.02毫米以下）组合聚合物和粘合 剂。 Guill提供各种十字头和内联管路模 具，具有固定或可调节中心，适用于单 挤压或共挤压应用。 该工具可用于加工 任何化合物，并具有公司的专利精密 Feather Touch同心度调节系统（即 Seal Right系统），该系统与Feather 挤出工具 ing manufacturers to use recycled mate- rial in the extrusion process because they can rely on the quality of the recycled pellets.” Design for Recycling is another impor- tant criterion for implementing a circular economy in the packaging sector. “In this respect, woven bags made of poly- propylene are the perfect example,” says Adrigan. “They are a mono-material packaging consisting of 99% PP – even if they are coated. Considering this, it is obvious that the bags should be collect- ed after usage and recycled. We want to promote and advance this process with our technologies.” Guill offers its extensive line of cross- heads and inline tubing dies in fixed and adjustable center, for single or co-extru- sion applications. The tooling is designed to process all compounds and features the company’s patented, precision Feath- er Touch Concentricity adjustment, the Seal Right System, which combines with the Feather Touch system to eliminate polymer leaking. Guill also offers its unique spiral flow distribution system. All Guill tooling is produced with rigor- ous computer simulation of the flow channels using Computational Fluid Dy- namics (CFD) programs, resulting in opti- mum uniform flow with no weld lines.
