SIKORA AG

The focus is on innovative measuring, control, inspection, analysis and sorting devices: at the SIKORA booth, visitors can expect a comprehensive portfolio of systems for quality control, process optimization and cost savings in the pipe, hose and tube as well as plastics industries.

For online inspection and sorting of plastic material, SIKORA showcases the PURITY SCANNER ADVANCED. The system combines X-ray with optical technology and detects contamination inside plastic pellets as well as on their surface. Perfection in detection provides 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 discolorations as well as “black specks” inside transparent and on opaque pellets, whereas color deviations are detected by color cameras. Contaminated pellets are sorted out automatically.

For sample testing or incoming goods inspection and analysis of plastic material, SIKORA presents the PURITY CONCEPT V at CHINAPLAS. Material samples, placed on a sample tray, are moved through the inspection area. Within seconds, the material is inspected automatically by a color camera and a projector marks the contaminated material directly on the sample tray. By analyzing the recorded images, contamination on the surface of transparent, diffuse and colored material are automatically detected, visualized and evaluated. A clear allocation of the contamination and follow-up inspection are possible at any time. The system is more accurate, more reproducible and more reliable than human, eye and manual light table, determines the size of contamination, and thus, contributes significantly to quality control and process optimization.

Furthermore, SIKORA offers systems for offline inspection and analysis based on X-ray technology that detect and analyze metallic contamination inside of plastic materials. For a 100 % quality control during the extrusion of pipes, SIKORA exhibits the CENTERWAVE 6000. Millimeter wave technology precisely measures the diameter, ovality, wall thickness and the inner profile (sagging) of the product. The measuring principle does not require any coupling media, is not influenced by temperature or the plastic material and measures precisely without the need of any calibration. A presetting of the product parameters is not required. Easy operation and precision lead to the highest quality of the final product as well as cost savings and optimal efficiency.

The X-RAY 6000 PRO is a further highlight for measuring the wall thickness, eccentricity, the inner and outer diameter and the ovality of hoses and tubes. Hereby, the thickness of up to three different material layers is measured. Furthermore, SIKORA presents diameter measuring systems of the LASER Series 2000 as well as LASER Series 6000, which also offer lump detection in addition to diameter measurement. SIKORA’s presentation in Shenzen is completed by reliable lump detectors that detect irregularities on the product surface. Further reading
