Introduction
imess GmbH, located in Witten, Germany, specializes in developing and manufacturing advanced optical measurement and test systems for industrial quality assurance. Established in 1998, the company serves a global clientele across various demanding sectors, including the spring, metal, medical, and plastics industries. imess is certified according to DIN ISO 9001:2015, reflecting its commitment to quality standards.
Core Offerings and Technology
imess provides a diverse portfolio of tailor-made optical inspection solutions utilizing camera and laser technologies. For the spring industry, key systems include the F435 for 3D compression and valve spring geometry, even under load (up to 2000 Newton force), the F881 for complex suspension spring geometries (measuring up to 300 mm diameter and 600 mm length), and the F610 for inline arc spring measurement, capturing all dimensions including flatness with high precision using telecentric lenses. The F210 system tests wire samples for contour and tolerances, reliably measuring complex convex contours.
For the metal industry, imess offers the SW series for highly accurate strip width measurement (up to 2400 mm, ± 0.01 mm accuracy), the S-TM for laser-based thickness measurement (µm accuracy via differential principle), and the S25 for circular knife analysis, detecting cracks and wear in seconds. The company also supplies measurement tables (SQ series) for 2D geometry of sheets and blanks, and systems like S28 for tactile burr height determination (1 μm resolution) and S30 for coil set and twist measurement. The S4 system automates quality control in cross-cut lines, measuring sheet geometry (up to 2100 mm width, 8000 mm length) at speeds up to 240 meters per minute.
Beyond these, imess caters to the medical and plastics industries with solutions for stent control, black spot detection, spout control, sealing tests, and in-mould-labeling (IML) inspection. Recent innovations extend to optical inspection systems for the glass industry, detecting minute defects, and modules for the wood industry, such as paint chamfer detection and automated stapling/de-stapling of panels.
Client-Centric Approach and Support
A distinguishing factor for imess is its comprehensive project management, which begins with individual in-depth consultation to clarify specific customer requirements and on-site assessments. The company emphasizes selecting technically suitable and cost-effective components, leading to bespoke, future-oriented systems. Post-installation support is extensive, offering services like 24-hour on-call duty, operator training, and maintenance contracts, ensuring long-term customer satisfaction and efficient system operation. Systems are designed for seamless integration into existing production lines, providing 100% inline control and operator-independent measurement results.
