SIKORA

SIKORA is a leading manufacturer of measuring and control technology as well as inspection, analysis, and sorting systems for industrial manufacturing. SIKORA solutions ensure the highest level of quality control and process optimization in the production of wires and cables, hoses and tubes, plastic sheets and films, optical fibers, and in the plastics industry. The company is headquartered in Bremen (Germany) and has been developing “Technology to Perfection” for more than 50 years.

What SIKORA addresses in practice

In continuous production, small deviations drive quality and cost – diameter, wall thickness, eccentricity, ovality, “sagging,” process stability, and the cleanliness of the incoming material. SIKORA delivers non-contact inline measurement and automated inspection to make production more stable, more efficient, and with lower waste.

  • Real-time quality control (inline) without stopping the line
  • Process optimization and reduced scrap / costs
  • Inspection and sorting of materials (e.g., pellets, flakes, tapes/films)

Portfolio: measurement, inspection, analysis, and sorting

SIKORA covers both inline measurement (e.g., diameter, wall thickness, ovality/eccentricity) and inspection and sorting – including X-ray solutions, optical methods, infrared analysis, and specialized systems for the wire & cable and plastics industries.

Wire & Cable – insulation and sheath quality

Solutions for wire and cable manufacturing: non-contact diameter measurement, wall thickness and eccentricity measurement (including X-ray), defect detection (e.g., “lumps/neckdowns”), and support for stable processes on insulation and sheathing lines.

Hose / Tube / Sheet – pipe and sheet extrusion

For hoses, tubes, and plastic sheets: measurement of thickness, ovality, and other parameters during extrusion, including solutions for large diameters and demanding applications (inline control without damaging the product).

Optical Fiber – consistent fiber quality

Systems for optical fibers and cables: measurement and control of critical parameters during manufacturing for higher yield and consistent quality.

Plastics – PURITY: inspection, analysis, and sorting

The PURITY series focuses on assessing the cleanliness of plastics materials (e.g., pellets, flakes, tapes/films) using X-ray, infrared, or optical technology – to minimize contamination and increase the quality of the final product.

Development, technology, and capabilities

SIKORA is a family-owned company with a global network and a team of 400+ employees. A significant share of its efforts is dedicated to development and innovation: the company states it invests around 10% of annual revenue in R&D, and that the Technology Center employs 30+ specialists. For X-ray measurement, SIKORA emphasizes radiation safety and compliance with international guidelines.
