Automatic Optical Geometry Inspection

Geometry inspection detects even the smallest deviations that are critical for function, safety and quality.

Glastellersystem zur Geometrieprüfung

Precision down to the smallest detail.

In geometry inspection, highly precise dimensional measurements of components are taken and reliably compared with the nominal values specified in technical drawings.

Highest measurement accuracy and process reliability: Measurement accuracies of up to ± 1 µm enable stable, reproducible results well within the drawing tolerances.

Maximum throughput and efficiency: Reliable geometry inspection of up to 100,000 parts per hour. Consistent, fatigue-free and without production interruptions.

Objective quality assurance and documentation: 100% inspection with automatic data capture, statistical evaluation and standards-compliant documentation of all measurement results.

Automated geometry inspection: Precision according to specification.

Dimensional deviations determine function and safety, regardless of how complex a component may be. Automated geometry inspection precisely captures relevant dimensions and directly compares them with the specifications defined in the technical drawing. The result is clear measurement data that reliably verifies quality in a reproducible manner and enables dependable evaluation of every single part.

Metal processing

Precise measurement for turned, milled and stamped parts

In metal processing, tight tolerances meet high production volumes. Geometry inspection ensures that turning, milling and stamping processes are reliably monitored and deviations are detected at an early stage.

Inner and outer diameters, radii, and form deviations

Inner and outer diameters, radii, as well as form deviations such as ovality or out-of-roundness are measured precisely and evaluated objectively, ensuring that even the smallest tolerance deviations are reliably detected.

Component height, length and material thickness

Component height, length and material thickness are captured without contact and continuously monitored to ensure consistent dimensional accuracy even at high production volumes.

Geometric tolerances (form and position)

Geometric tolerances such as flatness, perpendicularity, coaxiality, or complex contours are analyzed reproducibly to ensure that demanding drawing specifications are reliably met.

Function-critical dimensions

Function-critical dimensions on fastening elements are automatically inspected, generating clear measurement data that eliminates ambiguity and ensures assembly capability.

Elastomers

Geometry inspection for flexible materials

Elastomer components such as O-rings or seals are flexible, compliant and sensitive to handling and mechanical stress. Automated geometry inspection ensures that relevant dimensions are reliably captured despite these material properties and evaluated within the specified tolerances.

Inner and outer diameters

Inner and outer diameters as well as wall thickness and cross-section thickness are measured with high precision, as in elastomers these parameters directly determine the sealing performance and the component’s suitability for its intended application.

Component height and contours

Component height and contours are captured without contact to ensure reproducible measurement results even for soft or unstable parts.

Form deviations

Form deviations such as misalignment, irregular contours or deviations from the nominal geometry are reliably detected, even if the material deforms slightly during handling.

Plastics

Reliable geometry inspection for functional requirements

Plastic parts place specific demands on geometry inspection, as material properties such as transparency, reflectivity or flexibility can influence optical measurement. Automated geometry inspection precisely captures relevant dimensions and ensures that plastic series parts remain within defined tolerances.

Inner and outer diameters, geometric openings

Inner and outer diameters as well as geometric openings are reliably measured to ensure the dimensional fit and functionality of plastic components.

Component height, wall thickness and material thickness

Component height, wall thickness and material thickness are captured without contact, enabling reproducible inspection even for delicate or lightweight plastic parts.

Complex contours and form deviations

Complex contours and form deviations on injection-molded or precision-turned parts are analyzed with high precision, even in the case of demanding geometries or varying material properties.

Geometric tolerances

Geometric tolerances such as flatness, roundness, or concentricity are evaluated objectively to ensure dimensional accuracy and functional reliability in subsequent use.

Sintered parts 

Geometry inspection for porous and brittle materials

Geometry inspection of sintered parts enables reliable evaluation of critical dimensions and contours without misinterpreting permissible porosity as a defect. This prevents misclassification, unnecessary scrap and potential functional issues at a later stage.

Contours and topological features

Contours and topological features are measured reliably, even in complex-shaped sintered parts whose material structure requires a clear distinction between permissible porosity and geometric deviations.

Gentle handling and controlled sorting

Gentle handling and controlled sorting ensure that delicate sintered parts are not damaged during geometry inspection and remain reliably processed even at high production volumes.

Geometric deviations at edges and transitions

Geometric deviations at edges and transitions are reliably detected, enabling clear identification of form defects or impermissible changes in the component geometry.

Dimensional accuracy and key contour features

Dimensional accuracy and key contour features are precisely inspected to ensure that post-processed outer surfaces comply with the specifications defined in the technical drawing.

Electronic components & connectors 

Dimensional accuracy for reliable connections 

Geometry inspection ensures that electronic components are suitable for assembly and can be processed reliably in automated manufacturing processes.

Pins and connectors

Pins and connectors are precisely measured and checked for correct positioning to ensure a reliable mechanical and electrical connection within the assembly.

Assembled printed circuit boards

Assembled printed circuit boards are geometrically inspected to verify the completeness and correct placement of components before they are transferred to downstream processes or assemblies.

Micro-components

Micro-components such as fine screws or small turned parts are reliably detected, even at very small dimensions where handling and measurement place particular demands on the process.

Complex geometries and hybrid materials

Complex geometries and hybrid materials are analyzed from multiple views, enabling reliable evaluation of features such as coaxiality or concentricity even on combined material surfaces.

Precise measurement for consistent quality

Manual measurements and sampling are no longer sufficient given today’s tolerances, production volumes and liability requirements. Automated geometry inspection is therefore not merely a technical measure, but a strategic decision for stable processes, reliable quality and long-term trust.

  • Glastellersystem

    100% inspection and process reliability

    Geometry allows no exceptions.  

    Every component is measured completely, objectively and reproducibly. Automated geometry inspection systems from NELA eliminate human factors and ensure that only dimensionally accurate parts proceed to the next stage of the process. This reduces the number of non-compliant parts that pass as good, prevents downstream damage and creates true process reliability.

  • Glastellersystem

    All measurement results are automatically documented and remain fully traceable at all times. Geometry inspection provides reliable data both for internal process optimization and for audits, customer requirements and compliance with standards. Quality becomes measurable and verifiable.

  • Verbindungselemente

    Protection for brand, product & end users

    Avoid errors and their consequences.

    Geometric deviations are often invisible, yet their consequences can be severe. Automated geometry inspection detects critical deviations at an early stage and prevents defective components from entering assemblies or end products. This protects not only functionality and users, but also brand reputation and trust.
