Taking charge: developments in static control technology
Efficient removal of static charge from plastic products – from shopping bags to in-mould labels – can boost production speed and product quality. Lou Reade reports
Manufacturers of plastics products spend plenty of time and effort trying to shrink their electricity bills, in order to cut costs. At the same time, extrusion companies – especially those that make film – are trying to reduce another type of electricity: static charge. Removing static charge from plastic surfaces has many benefits – which can include higher production speeds, less downtime and better quality products. At K2016, Eltex of Germay introduced two new
systems that it says boost efficiency and perfor- mance in the removal of static charges from plastics.
Its R60 is a patented AC discharge bar with a
freestanding air-supported spring tip, which the company says achieves a very high passive discharge effect. This enables active operation even at a low level of high voltage AC.
A small amount of air can be blown through the spring tip to increase the range. This is also used to clean the emission tips continuously. The bar’s aluminium profile is equipped with a highly insulating, mechanically robust layer that – in combination with the freestanding spring tip – causes a large increase of ion production. Eltex cites a number of benefits, including: superior
discharge performance at close range; high ranges at the lowest possible level of high voltage; and, flexible use in narrow and grounded machine environments. At the same time, it is now offering its SDS Smart
Discharging System – a fully integrated 24V discharge technology for mid-size distance and speed areas – with Connected Control, for convenient, intelligent monitor- ing control. Here, all control data from the process – such as
system status, actual values, current/voltage, error messages, conductivity and pollution of the bar – can be

called up and configured directly using a touchscreen. Feature of the new system
include: casing in 7 or 12.1in; depiction of all relevant system states; and, input/saving of electrode process data.
The company’s systems are applied across the
plastics industry, with a focus on converting and laminating, as well as printing, packaging and finishing production environments. Eltex says that its systems enable higher production speeds, more efficient work, increased quality, reduced energy consumption, fewer faults and less downtime and spoilage.
Ready for 4.0 Simco-Ion says that its IQ Easy platform, which it showcased at K2016, is fully prepared for the new environment of Industry 4.0. IQ Easy connects up to 30 anti-static devices into a
network. It allows all parameters to be controlled centrally, by the Manager IQ Easy, while allowing devices to interact with one another in order to optimise efficiency. Up to 32 static control devices can be controlled by one Manager IQ Easy. Warnings and alarms give the operator insight in the status of all devices. Advance notice of a problem – such as if an anti-static bar needs
