Vision Inspection Systems

Automated vision inspection systems delivering accuracy, consistency, and traceability across modern manufacturing.

Vision Inspection Systems for Automated Quality Control

Curtis Assemble & Test Ltd has been designing and integrating vision inspection systems for over 25 years, supporting manufacturers across a wide range of industries. Vision inspection has become a vital tool in modern manufacturing, enabling automated inspection, quality control, and traceability at every stage of production.

Our experience allows us to deliver bespoke vision inspection solutions tailored to your specific requirements, whether as part of new automated machinery or retrofitted into existing equipment. By combining high-resolution cameras, intelligent software, and carefully engineered lighting, our systems help reduce manual inspection, improve consistency, and maintain high product quality in demanding production environments.

Automated Inspection & Quality Assurance

Vision inspection systems provide real-time inspection and verification as part of automated manufacturing and assembly processes. From presence and absence detection to dimensional measurement and defect identification, these systems support fast, accurate decision-making without interrupting production flow.

Typical applications include dynamic analysis of injection spray patterns, parts counting and verification, surface defect detection, and supporting leak detection processes. By automating inspection tasks, manufacturers can reduce operator dependency, improve repeatability, and achieve higher throughput while maintaining strict quality standards.

Lighting, Integration & System Expertise

Achieving reliable inspection results depends heavily on correct lighting, camera positioning, and system integration. Poor lighting is a common cause of inconsistent inspection performance, particularly when vision systems are retrofitted into existing machinery.

With decades of hands-on experience, CAT designs vision inspection systems with application-specific lighting and optics to ensure consistent image capture and repeatable results. Our systems integrate seamlessly with PLCs, HMIs, and existing control architectures, delivering dependable inspection performance within real-world manufacturing environments.

Traceability & Code Verification

Modern manufacturing increasingly relies on accurate part traceability to support quality control, process validation, and regulatory compliance. CAT vision inspection systems are designed to reliably read and verify a wide range of codes, including QR codes, Data Matrix codes, linear barcodes, and RFID tags, even on challenging surfaces or within demanding production environments.

By integrating code verification directly into the inspection process, our systems enable manufacturers to link individual components to inspection results, process data, assembly records, and full production history. Each scan can be logged within a central system, providing easy retrieval of manufacturing data for audits, troubleshooting, and quality investigations.

This ensures all required process steps are completed before components progress through production or into dispatch, reducing the risk of unidentified defects, preventing costly errors, minimising waste, and improving overall product quality.

Nozzle Opening Pressure Optimisation (NOPAT)

Precise control of nozzle opening pressure (NOP) is critical to injector performance, directly influencing atomisation quality, delivery rate, and overall combustion efficiency. CAT NOPAT systems accurately measure and optimise nozzle opening pressure under controlled test conditions, ensuring consistent spray characteristics and repeatable injector performance.

By integrating high-speed vision analysis with pressure and flow measurement, our systems evaluate plume orientation, radial spray angles, and delivery parameters in real time. Where required, nozzle settings can be fine-tuned to achieve defined pressure targets, ensuring compliance with performance specifications and reducing variability across production batches.

The result is a fully validated injector with optimised opening pressure, verified atomisation behaviour, and complete traceability of test data for quality assurance and audit requirements.
