EXHIBITION PREVIEW | K2019 – MACHINERY
Elmet is showing its technology for LSR moulding at K2019, with a particular focus on its enhanced TOP 5000 P pneumatically driven dosing system which has a smaller footprint than its predecessor. It is also preparing for the commercial introduction of a TOP dosing system with a fully electric dosing pump which is driven by a torque- and current- controlled servomotor. The focus is on minimizing dosing fluctuations and maximizing efficiency and simplicity of operation. Both versions are intended for the mass production of high quality parts with tight tolerances. They cover shot weights from less than 0.1 g up to several kilogrammes and viscosi- ties ranging from 9,000 mPas to 3,000,000 mPas even when the viscosities of the two components differ greatly. �

Engel is making the Circular Economy one of its major themes at K2019, in common with a number of other machinery (and materials) companies. It says one of the priority
Above: Engel will use roll-to-roll IMD injection moulding to produce three-dimen- sional sample parts with different decor
tasks on the way to the Circular Economy is to open up a broader range of applications for processed plastic waste. The intelligent iQ weight control assistance system is being used at Engel’s stand to process fully recycled ABS. The software from Engel’s Inject 4.0 program ensures a constant melt volume during injection to ensure consistently high product quality, even with strongly fluctuating raw material quality. Engel is also showing transport boxes using recycled material in a sandwich- moulded structure. The boxes are made using the Engel Skinmelt process. In automotive, Engel is putting the spotlight at K
on its Foilmelt and Clearmelt processes. A demon- stration of Foilmelt’s roll-to-roll IMD process will produce three-dimensional sample parts with different decor on a Victory 1060/300 moulding machine with an integrated Viper 20 linear robot. An all-electric and tie-bar-less E-motion

310/120 TL machine will be used in a demonstration of PMMA processing for LED lighting. Engel’s hot runner partners INglass and HRSflow are involved with this application, as are Volvo and Arkema. A novel approach to
producing thick-walled hous- ings of medical devices in shorter cycle times is also being shown. A
INJECTION WORLD | September 2019
two-component process is made possible with an 8-cavity Vario Spinstack mould from Hack Formen- bau used on the cleanroom version of an all-electric E-motion 310H/170W/160 combi injection mould- ing machine. The machine is equipped with a vertical indexing shaft with four positions: the first for injection moulding the bodies, using a transpar- ent polypropylene from Borealis; the second for cooling; the third for applying a second layer of PP to the pre-moulded parts; and the fourth for a Viper 20 speed robot to step in and remove the parts. Engel has a number of other demonstrations for
applications in lightweight overmoulding of organosheet, packaging and other focus areas. �

Frigel says it will bring to the K show its complete portfolio of advanced cooling solutions for the plastics industry. On its stand will be the latest upgrade of its patented Ecodry System. This adiabatic cooling technology will be presented in its glycol-free, self-draining configuration, with an inverter driven pumping station and new digital control panel. It will also show its traditional ranges of Microgel portable chillers for injection mould- ing: RCM/D Series for throughputs from 10 to 900 kg/hr, and Microgel for Packaging, RCP Series, from 100 to 2,000 kg/hr, both with new digital technology and touch screen control. For engineering resin moulders Frigel has four
new Thermogel temperature control units. The TBD Series – up to 90°C – is for general moulding applications. The TDK Series – up to 120°C – and TPK Series – up to 180°C – are pressurised water TCUs for high temperature applications. The new Thermogel Heat&Cool THC Series are process synchronized alternating heating and cooling units that work with pressurised water up to 180˚C. These units are designed specifically for high quality surface finishing of moulded parts. �

Fu Chun Shin (FCS) is showing a new injection moulding machine on the stand of its German partner Windsor. The FA-160 is a servo-hydraulic toggle machine with 1,600 kN clamping force. In the K2016 demonstration, the machine works with a robot system from Wemo to mould PP
snack boxes from Miraplast, Austria, 82 g in weight.
The FA series from FCS is the succes- sor to its SD series in the clamping force
