Sikora shows range of tube products at NPE SIKORA, a manufacturer of innovative measuring, control and sorting

enables fast centering of the extrusion tools and automatic control of the minimum wall thickness for optimum material usage and overall sustainability as well as cost saving. With the X-Ray 6000 Pro, Sikora presented a system based on X-ray technology that continuously provides measuring data on wall thickness, eccentricity and inner and outer diameter of hoses and tubes in extrusion lines. These are clearly displayed on the monitor of the Ecocontrol 6000 processor system. The X-Ray 6000 Pro can be used either after the extruder, between two vacuum tanks/cooling sections, or at the end of the line for cold measurement. From the first day of commissioning, the system enables the wall thickness to be reduced to the smallest permissible value. This results in significant material and cost savings for the user. At NPE Sikora also exhibited the Purity Scanner Advanced that is used for inspection and sorting of plastic pellets. Even the smallest, critical contamination are reliably detected and sorted out by the system. Thanks to the modular concept, different camera types can be used depending on the inspected material. In addition to optical 25µm high-resolution cameras, which detect black specks and discolorations, an X-ray camera can be installed to detect metallic contamination down to 50µm in the pellet. Common systems on the market have a maximum of two optical cameras. However, these quickly reach their limits due to relatively low coverage as soon as the contamination are outside the cameras’ field of view. The Purity Scanner Advanced automatically sorts out detected contamination via a blow-out unit. For optimising the by catch, Sikora has also developed a ‘hybrid blow-out’ feature. In the area of plastics, visitors were able to bring small quantities of opaque and amorphous pellets, flakes or plates to be inspected and analysed for impurities with the inspection and analysis system Purity Concept V during the exhibition. The system is suitable for reproducible laboratory applications and detects black and coloured contaminants from a size of 50µm as well as discolorations.

technologies, recently exhibited its wide range of technology for quality control and cost optimisation in hose, pipe and tube extrusion and material production and processing at NPE 2024 earlier this month in Orlando, USA. At NPE 2024, Sikora presented new measuring devices that aim to redefine the segment of measuring technology for hose and tube extrusion lines. “Our customers can look forward to reliable, future-oriented products that continue to offer excellent performance and make a significant contribution to increasing productivity and cost efficiency in production,” said Katja Giersch, head of corporate communications at Sikora. Visitors were able to see the benefits of the systems for themselves live at the exhibition stand. For measuring tubes and pipes with a diameter from 32mm to 1,600mm, Sikora showcased the Centerwave 6000 at NPE. All models of the Centerwave 6000 device series are characterised

by their innovative measuring principle based on millimeter wave technology. Operation is intuitive at the push of a button. Once activated, the operator immediately receives continuous and precise measured values – without pre setting the product parameters, without the influence of a coupling medium (water) and without any calibration. Right after the first vacuum tank, the system provides all product dimensions. A continuously rotating transceiver measures the diameter and wall thickness in 360 degrees across the entire product circumference. The extensive and precise measuring data

When you´ve got no second try, it´s all in your hands.
