Inner coating for small products
Germany’s Institute for Plastics Processing (IKV) – part of RWTH Aachen University – will exhibit a range of its technologies during K2019.
As well as showcasing projects in injection moulding and additive manufacturing, IKV’s team of plasma scientists will show a modular,
scalable plasma unit that they have developed. It can be used to coat the inside of small hollow articles, such as medical syringes and ampoules, says the team. Possible uses include increasing the barrier effect against gases and aromas, reducing friction or improv- ing chemical resistance.
The DTA 160 can be installed as an individual component or as part of a new overall system, and can also be retrofitted to existing pipe extrusion systems. One major pipe manufacturer has already incorporated a prototype of the new cutting unit into its day-to-day production activities.
High cut rates UK-based Gillard will exhibit its new extrusion servo rotary cutter at K2019. The Servo-Torq Plus extrusion cutter is designed for plastics, rubbers and many non-polymeric materials. It combines Lenze brushless AC servo motors with a digital multi-axis control system to activate the rotating knife blade. Gillard says very high cut rates are possible, with precise cut length accuracy. At the same time, Siemens widescreen touch panels allow easy operator control of the machine. The cutter is available with maximum diameter

cutting capacities of up to 150mm. All types of plastic and rubber extruded material can be cut with the machine. Integral twin-belt Accra-
Feed caterpillar infeeder/ puller machines are provided to match every cutter model. These feature direct drive AC motors and planetary gearboxes, which improve speed control at high extrusion speeds. The machine has a high
level of connectivity: ProfiNet allows networking with the rest of the extrusion line, while remote service is
available via the Internet using the built-in VPN router.
44 PIPE & PROFILE EXTRUSION | September 2019
At the show, the scientists will demonstrate the automatic coating of plastic syringes, including the handling of specimens. Visitors will be able to compare the friction-reducing effect on coated syringes with that of uncoated ones. IKV scientists will be on hand to demonstrate the machines in operation and explain the processes.
Dimension measurement Zumbach of Switzerland will showcase a range of its technologies that measure pipe and tube dimensions quickly and accurately. Its Wallmaster is a based on ultrasonics, while its
Rayex system uses X-rays to measure wall thick- ness, eccentricity, diameter and ovality. The optimal technology can be selected for every application and specific requirement, it said. In addition of gaining control over the produc-
tion process and product quality, full data acquisi- tion and production transparency helps customers as they move towards Industry 4.0 implementation, the company added.
Other devices such as its Odac laser diameter
gauges, KW lump-neckdown detectors and non-contact length measurement systems further improve process control, and provide full transpar- ency of the production process – including for complex multi-layer products. The Odac laser diameter gauge can make up to 9000 calibrated measurements per second. A per- manent, precise diameter and ovality measurement in combination with flaw detec- tion – all in one unit – makes it ideal for tube and hose extrusion lines. Tailored to the applica-
tion, a selection of 1-, 2- or 3-axis Odac laser diameter gauges are available. These can be supplied in combina- tion with powerful Usys display and control systems, which offer statistics, process control and data archiving. At the same time, its
Profilemaster systems offer full cross-section measure-
ment of plastic and rubber pipe
