  • Japan’s Sodick will exhibit the GL30 electrichydraulic hybrid machine, targeted at the micro medical, E&E and telecoms sectors. Whereas conventional machines melt, meter and inject the polymer using a reciprocating screw and check valve, Sodick says it uses the V-Line injection method to prepare the polymer shot by weight, allowing for more accurate filling and pressurisation of the component. In addition, the machine is capable of linear injection speeds in excess of 1,300 mm/s and can maintain this speed within a 5 mm shot size whilst accelerating and decelerating within 1 mm of plunger movement.

Auxiliaries/Controls

  • Arburg will showcase the filling assistant, developed together with partner Simcon, on its newest Gestica controller on an all-electric Allrounder 570A model. The simulation model created offline and part geometry are read directly into the control system, where the degree of part filling, relative to the current screw position, is animated in real time as a 3D graphic. The machine operator can compare the results of the simulation created offline with the actual filling performance in the last cycle on the screen monitor. This helps to optimise the filling profile. Also new is the plasticising assistant for material processing and maintenance of the screw, and the control system simulator. Meanwhile, the new Arburg Turnkey Control Module (ACTM), a SCADA (supervisory control and data acquisition) system for complex turnkey cells, visualises the complete process, captures relevant data, and transmits job-specific data sets to an evaluation system for archiving or analysis.

  • Arburg will also exhibit the arburgXworld customer portal, featuring free functions such as the main Machine Center, Service Center, Shop and Calendar apps, with additional fee-based functions to be introduced. These include the Self Service dashboard for machine status, control system simulator, collection of process data, and details of machine design.

  • In screws, Engel will present the PFS (Physical Foaming Screw) developed for structural-foam moulding with direct gas injection, with better homogenisation of the gas-loaded melt and longer life with glass-fibre resins. It will be demonstrated with US firm Trexel’s MuCell microcellular foam process. The LFS (Long Glass Fibre Screw) is for increased use of long-glass fibre PP and nylon in automotive applications. It allows for uniform distribution of the fibre, maximising plasticising consistency when processing rod granules, and reduces fibre breakage, with optimised screw geometry.

  • Engel will also show its iQ melt control that automatically adjusts plasticising time to minimise screw/barrel wear, and the iQ process observer with artificial intelligence. The observer analyses several hundred process parameters in plasticising, injection, cooling and demoulding, making it easy to spot changes at an early stage.

  • Italy’s Sacmi will showcase the PVS10L, equipped with its new, patented control system. With the PVS10L, the preform line is transformed into a system that can “self-learn” all the required checks. This simplifies QC procedures and improves working conditions for operators, who can work directly on the line without having to manually set inspection recipes, the complexity of which reflects the growing sophistication of the products and customers’ changing needs.

  • Trexel’s latest developments for MuCell include an expanded TecoCell line of chemical foaming products, the P-Series gas-metering unit, suitable for fast cycle packaging applications, and the new Tip Dosing Module (TDM). The latter eliminates the need for a special screw/barrel, can be retrofitted on standard screws, is gentle on fibre-filled resins, and boosts outputs.

  • Wittmann Battenfeld will demonstrate its HiQMetering for positive closing of the check valve prior to injection. Another new element of the Wittmann 4.0 is the electronic mould data sheet, which stores settings for both the injection machine and parent company Wittmann’s auxiliaries to permit setup of an entire cell in a single stroke. Having bought a stake in Italian MES software supplier Ice-Flex, it will also exhibit the TEMI+, said to be an entry-level datacollection system integrated with the machine’s Unilog B8 controls.

  • Having set up the Digital & Service Solutions (DSS) business unit, KraussMaffei offers a retrofit programme to equip all its machines with webenabled networking and data-exchange capabilities for Industry 4.0. Offered will be condition monitoring for predictive maintenance and data analysis as a service under its Social Production app. This patent-pending function identifies process disturbances autonomously, based on underlying data, without any user configuration, and provides tips on possible solutions.

  • Japan’s Nissei will present its new TACT5 controller equipped as standard with both the OPC UA communication protocol and the Euromap 77 (basic) MES communication protocol. This allows the machine controller to be the core of a network of auxiliary equipment like a robot and material feeder. Wireless networks minimise wires and cables and permit remote maintenance. Nissei says it is also developing its N-Constellation concept for an IoT-based automatic quality inspection system.
