Tube inspection & testing technology

Measuring, control, inspection and analysis at Chinaplas 2019

Themeasuring principle does not require any coupling media, is not influenced by temperature or the plastic material, and measures precisely without the need for calibration. Pre-setting of the product parameters is not required. Sikora AG – Germany

technology that detect and analyse metallic contamination inside plastic materials. For 100 per cent quality control during the extrusion of pipes, Sikora exhibited the Centerwave 6000. Millimetre wave technology precisely measures the diameter, ovality, wall thickness and the inner profile (sagging) of the product.

The focus of Sikora’s appearance at this year’s Chinaplas in May was on innovative measuring, control, inspection, analysis and sorting devices. At the company’s booth, visitors saw a portfolio of systems for quality control, process optimisation and cost savings in the pipe, hose, tube and plastics industries. For online inspection and sorting of plastic material, Sikora showcased the Purity Scanner Advanced, which combines X-ray and optical technology to detect contamination inside plastic pellets as well as on their surface. Detection is enhanced by the adaptive camera concept, where up to three optical cameras are used, depending on the expected contamination and application. For example, an X-ray camera detects metallic contamination inside pellets, optical cameras identify yellow discoloration and “black specks” inside transparent and opaque pellets, while colour deviations are detected by colour cameras. Contaminated pellets are sorted out automatically. For sample testing or incoming goods inspection and analysis of plastic material, Sikora presented the Purity Concept V at Chinaplas. Material samples, placed on a sample tray, are moved through the inspection area. Within seconds, a colour camera automatically inspects the material and a projector marks the contaminated material directly on the sample tray. By analysing the recorded images, contamination on the surface of transparent, diffuse and coloured material is automatically detected, visualised and evaluated. A clear allocation of the contamination and follow-up inspection are possible at any time. The system is claimed to be accurate and more reliable than the human eye and manual light table, determining the size of contamination and contributing significantly to quality control and process optimisation. Sikora also offers systems for offline inspection and analysis based on X-ray
