The solution
CarnaudMetalBox successfully modernized its engineering documentation workflow, improving efficiency in equipment maintenance, manufacturing optimization, and service support. GTX solutions helped the company future-proof its technical archives, reinforcing its position as an industry leader in packaging innovation.

CarnaudMetalbox: Improving packaging production efficiency
CarnaudMetalbox, a leading packaging manufacturer, required better document management for 25,000+ mechanical drawings. GTXRasterCAD® introduced hybrid editing, automated raster enhancements, and standardized title blocks, enabling faster modifications and improved workflow integration.
CarnaudMetalBox Closures UK, part of the Crown Cork and Seal Company, operates one of Europe’s leading packaging plants. With a daily production of 5–7 million caps, their facility in Poole, UK relies on advanced engineering machinery to manufacture high-volume screw-top closures for food and beverage containers. Managing over 25,000 mechanical drawings, the company required an efficient digital archiving and editing system to streamline design updates and equipment modifications.
Challenge
CarnaudMetalBox faced challenges in maintaining thousands of technical drawings, many of which were paper-based and manually updated.
- Engineers needed a way to efficiently update machinery schematics as production equipment was frequently retooled and modified.
- Paper drawings made retrieval slow and modifications labor-intensive.
- A scalable digital archiving solution was necessary to ensure all drawings remained accessible and up to date.
Solution
CarnaudMetalBox digitized all 25,000 drawings, storing them in electronic archives for fast retrieval.
- Engineers leveraged GTXRasterCAD® hybrid raster and vector editing tools, allowing seamless modifications without full vector conversion.
- Raster drawings were image-enhanced, cleaned, cropped, and corrected using GTX's intelligent editing tools.
- The raster title block and border were replaced with CAD-based versions, ensuring consistency across documents.
- Updated drawings were made accessible via networked viewing stations and HP DesignJet plotters, simplifying collaboration.
Result
By adopting GTX technology, CarnaudMetalBox achieved:
- Faster drawing modifications—eliminating manual redrafting.
- Improved accessibility, allowing engineers to view and update schematics across multiple departments.
- Seamless AutoCAD® integration, ensuring engineering workflows remained efficient.
- Enhanced service delivery to key departments, including the Tool room and Spares purchasing divisions.
"The capability that the GTX products give us to keep our scanned drawings up to date will ensure that GTXRasterCAD® remains a fundamental part of our new systems."
