Extrusion Asia Edition 2-2022

47 Extrusion Asia Eidition 2/2022 ➠ battenfeld-cincinnati www.battenfeld-cincinnati.com K 2022: Hall 16, Stand B19, FG -CE12 2022K展：16号展厅，B19号展位 flatness and lowest thickness tolerances is created, which is perfect for flooring applications. Yet not only for floor cover- ings, but also for manufacturing refrige- rator panels or other surface panels made of PS or PP, the roll stack is in demand in- ternationally and already being used in many countries. At the K booth, a Multi- Touch roll stack will be exhibited, so that interested customers can exchange views with the relevant specialists about its wide range of applications, which even include the production of thin film smoothed on both sides. battenfeld-cincinnati also offers perfect extruders for the PVC industry. The most recent proof is the new pelletizing extru- der series aglomEX, available either with or without electrically driven shear gap adjustment (EMS). These extruders are suitable not only for virgin material, but also for PCR goods originating, for exam- ple, from the Rewindo collection system. The immediate eye-catcher on the model aglomEX 114 to be showcased at the booth is the processing unit lengthened by 6 D, with which all five models have been fitted. In this way, the extruders not only meet the demand of the PVC indus- try for capacity to process a range of raw materials as wide as possible, but they also achieve up to 20% higher output rates in response to the general call for high efficiency. On course towards fully automatic extrusion lines Automation and digitization not only fa- cilitate daily production processes, but also fulfill the requirements for high effi- ciency in production, reduced set-up times and low scrap rates. Impressive ex- amples are the systems developed by bat- tenfeld-cincinnati for pipe and sheet production and presented at this year’s K. Fast dimension change (FDC) is a system which enables changes of pipe dimen- sions within a wide range of diameters at the push of a button during production. Not only the melt gap on the pipe die, but also all downstream aggregates ad- just themselves simultaneously to the new pipe dimensions without any manual intervention. So, pipe manufacturers are able to fill even small-volume orders effi- ciently and to minimize the amount of scrap as well, which makes their produc- tion eco-friendlier. Similar helpers in daily production are on offer for sheet and board extrusion lines. For instance, com- bined operation of the extruder and the melt pump in sheet extrusion significantly facilitates start-up. This saves time and costs and minimizes start-up scrap. Auto- matic adjustment of the flat-sheet die and the roll stack, as well as the roll compen- sation system, also simplifies the opera- tion and increase the efficiency in production. At the K, battenfeld-cincinnati will also present Steady flow from its extensive range of individual modules, which is the solution to reduce pressure fluctuations in PVC extrusion. In the counter-rotating co- nical twin screw extruders frequently used in PVC extrusion, pressure fluctuations in- side the die are unavoidable, due to the chamber profile. Yet these fluctuations may degrade the quality of the semi-fi- nished product. Steady flow takes care of measuring the pressure at the screw tip, and on that basis constantly readjusts the screw speed. This minimizes pressure fluc- tuations and consequently pulsations in the melt flow, which in turn ensures si- gnificantly better semi-finished product quality and reduces the amount of scrap. Gerold Schley is confident: “With our trade fair presentation, we will impres- sively demonstrate that we have under- stood the needs of the industry and are offering solutions. These range from op- timized individual components to com- plete lines, including digitization tools as well to facilitate daily production and to enhance production efficiency in every aspect”. He is looking forward to many interesting and above all face-to-face conversations in Düsseldorf. BOPP和BOPET： 在BOPP和BOPET这两种最受欢迎的包 装薄膜的生产中，迄今为止，生产速度 的基准约为600m/min。在K展会2022， 布鲁克纳机械制造将展示具有显著更高 运行速度的新的生产线概念。 BOPA： 聚酰胺制成的BO薄膜特别适用于包装油 性、高脂肪食品和冷冻食品。对此的需 求不断增加，相应的薄膜拉伸线的需求 也随之增加。 在K展会，布鲁克纳机械制造将推出 新的生产线类型，产量将增加80%——生 产速度从220m/min提高到350m/min，生 产线的宽度从6.6m扩大到7.4m。 n 在对抗气候变化的过程中，在可预 见的未来，如果没有以节约资源的方式 生产的塑料包装，就不可能做到这一 点。这就是为什么布鲁克纳机械制造 （Brückner Maschinenbau）坚持其雄 心勃勃的目标，即除了发展快速发展的 循环经济之外，进一步提高薄膜生产效 率。这就意味着要减少原材料的使用， 将能源消耗降低和在薄膜生产中的“零浪 费”。 更快更宽的BO工厂 薄膜拉伸线的效率越高，产量越 高，单位能耗越低。这些参数主要受生 产线速度和宽度的影响。 在K展会2022上的技术创新—— 为可持续的薄膜生产提高工厂效率 电池隔板箔和电容器箔： 在这些部分中，之前（已经不包 括）5.5m的生产线宽度逐步增加到6m 以上，相关产量增幅超过20%。此外， 电容器薄膜的连续拉伸和同步拉伸技术 得到了进一步发展：重点是提高薄膜产 量和优化薄膜性能，特别是2µm范围内 的薄膜。 提高薄膜制作可持续性的技术创新 直接回收： 由于一种新型的“直接起绒”，生产 过程中产生的边角料和废料可以以更高 的百分比直接反馈到挤出过程中，而无 需任何再造粒过程。这节省了能源，节
