Thanks to the modular system from Koch, various drying containers with capacities of 20-600 litres can be integrated into Ekon. Safe operation of the dryer is ensured by micro

filters, overload protection, air check and tempera- ture limiter. The drying process is constantly monitored via sensors. Dry air with a dew point of -55°C can be produced to absorb moisture from the granulated plastic and to achieve the required residual moisture content of the dried material. Using an Ethernet connection, the device can be connected to a corporate network to control the drying centrally. The new dryers are also equipped with the OPC-UA open interface standard, allowing data exchange between production machines and peripherals independent of the manufacturer. �

Maillefer presented a number of its technologies at K2019 – including a range of coilers, and machinery to make irrigation pipe. Its KWA coiler is for medical applications. Its main value is in the mechanisms and precision machined parts of its two stainless steel turrets. The knowhow programmed into the traversing process overcomes the challenges of planetary rotation during transfers and tube acceleration dynamics, says the company. The unit keeps pace with lines running at speeds over 300 m/min. It can wind medical tube into coils of 620mm in diameter. It also offers the KWD, for reeling blown fibre

microduct and some automotive tubes. A new multi-axis traversing system guides the tube to form highly regular lays, even on irregular wooden reels. Along with a redesigned dancer, the travers- ing system maintains full control even at line speeds of up to 300 m/min. The KWI, for thin-wall micro-drip irrigation, has a

smart traversing process that anticipates and compensates for the effect of reversing lay direc- tions. This eliminates gaps between the wound tube and the reel flange – to give a perfectly full reel from edge to edge. The reeler reaches up to 400 m/min and is available in rear or lateral reel unloading versions. Maillefer also presented information on two new

extrusion lines in the micro-drip irrigation portfolio. The first produces thin-wall laterals with mini-flat emitters that is already in the field. The second is for thin-wall continuous labyrinth tape that is undergoing final proof tests before customer delivery. Both are complete systems. “These lines broaden our portfolio, giving us the

responsiveness needed to meet varying customer demands,” said Ernst Geider, sales director for pipe

Metravib, a specialist in dynamic mechanical analysis, has improved DMA and fatigue testing by extending the capabilities of its DMA+ series. Fully automated DMA testing in shear, compres- sion and tension

Xpander is an automated specimen handling system that is designed to boost the productivity of the DMA+ series and can provide tests round the clock in compression, tension and shear. The DMA+ series testing capabilities are

extending with a brand new Multitest crack growth software module coupled to a motorised video camera. Using specimens up to 80mm wide, it is possible to follow up to four cracks in one single test. The crack length measurement can be performed with a resolution better than 2 microns. “Xpander and the new DMA+ series have been designed taking account of industrial expectations in terms of accuracy, performance, productivity and ergonomics, as expressed by worldwide leaders in the rubber and polymers sector. With 50 years of experience in the field, we are the ideal partner,” said Hugues Baurier, worldwide sales manager. �

Pixargus has developed a device that combines dimension measurement with surface inspection. Its iProfilControl (iPC) can be used to check a variety of products, including window profiles, cable conduits and skirting boards – at high extrusion throughput rates. Flaws occurring during production can be detected early and corrected in real time. This saves feed material and reduces out-of-spec
