50 TRADE SHOW PREVIEW PET planet Insider Vol. 19 No. 04/18 www.petpla.net Mixing and dosing In the field of auxiliary equip- ment, Eisbär ma- nufactures sys- tems to improve quality and pro- ductivity for the plastics industry focusing on sys- t ems t o av o i d condensation on moulds, cap cool- ing, drying of plas- tic resin, process- ing PET flakes, crystallisation as well as mixing and dosing. The E i sbä r mixing and dosing unit for high mate- rial throughputs is a tailor-made system solution for accurate mixing and dosing of materials and additives. Amongst the many features of the system is a high throughput (up to several tons per hour), high accuracy, since each component has its own weighing system. Hot material can be processed and mixed simultaneously. Stored recipes allow reproducibility. The unit has 100% network connectivity and a final feature is that no pre-mixer is required. How the unit operates The principal materials and additives are supplied and filtered using optional grating filters. The weighing and dosing hoppers are filled accurately by means of screw conveyors, and can be continuously discharged for further processing. The unit is capable of accurately mixing and dosing differ- ent materials and additives, and offers a visual and graphic overview of the various dosing units and the set recipes. www.eisbaer.at Mould making, refurbishing and conversion services The advantage of mould conversion over buying a brand new mould lies in the lower capital investment involved. SIPA’s mould refurbishing and conversion services in China are an important element of its PET preform and bottle mould offering.The existing mould shoe is reused, and return of investment is faster. Customers can choose which is best for them by having a mould audit carried out by SIPA experts. The state of wear of mould components can be assessed in their own plant, and different options on refurbishing or conversion can be proposed. The mould refurbishing and conversion services comple- ment SIPA’s in-house capability to develop and produce high performance moulds and hot runners in-house. The hot half of each SIPA mould requires maintenance only after five mil- lion cycles, and it is possible to maintain components such as piston, flange O-rings and pin valves without opening the whole mould. The company’s range of solutions benefits from SIPA’s special focus on reducing energy consumption. With better distribution flow and a higher water temperature (14-15°C instead of 8°C), water consumption is minimised and per- formance in terms of condensation reduction is improved. The smooth, polished, rounded profiles on SIPA hot run- ners reduce stress on material, resulting in better preform quality and a reduced acetaldehyde (AA) level. Mould sys- tems also exhibit enhanced cooling performance, resulting in high quality preforms, maximum productivity and reduced production costs. SIPA’s service center in Hangzhou, China, in operation since 2004, complements two others in Italy and the USA. www.sipa.it Hall 2 Booth B51 Hall 4.1 Booth C71 inject 4.0 With intelligent assistance systems such as iQ weight control, Engel makes it easy for its customers to ensure consistently high product quality, even without specialist knowledge. The iQ systems continually analyse critical process parameters and readjust them automatically, shot for shot. The result is a self-optimising injection moulding machine. The growing intelligence of the machine control is a key feature of the smart factory, the goal of Industry 4.0. Networking of production systems and systematic use of machine, process and production data additionally help to raise the productiv- ity, quality and flexibility of manufacturing. Under the name of inject 4.0, Engel already offers a series of mature products and solutions for digitalising and networking injection mould- ing production that have proven themselves in practice many times. These generate considerable benefits both in isolation and as part of a digitalisation strategy encompassing the entire production operation. Engel is demonstrating the potential of the inject 4.0 solutions in the production of inject 4.0 logos on a tie-bar-less and fully electric e-motion 80 TL injection moulding machine. The CC300 machine control is capable of simulating process fluctuations so that the automatic readjustments by the intelligent assis- tance systems can be tracked on the display. While iQ weight control maintains consistent injected melt volume throughout the injection moulding process, iQ clamp control monitors the mould breathing in order to calculate and automatically adjust the optimal clamping force. www.engelglobal.com Hall 5.1 Booth E71
