NVision’s CT Inspection Helps Bottler Eliminate Sealing Flaws

April 30, 2016

(Southlake, TX; April 2016) – CT inspection and reverse engineering from NVision, Inc. helped a major beverage manufacturer resolve sealing flaws in its larger-sized bottles.  NVision, a leader in U.S. reengineering services and technology, utilized  its advanced computed tomography (CT) scanning technology to inspect the sealing surfaces of the bottles and reverse-engineer them so that the sealing problems could be isolated and resolved.

The beverage-maker, which produces soft drinks and other beverages, was producing bottles with perfect seals. However, when certain bottle sizes were scaled up in size, sealing flaws began appearing. The manufacturer’s engineers examined the bottles and the manufacturing process but were unable to find the cause of the problems. The manufacturer then brought in NVision, nationally known for its highly accurate scanning and reverse engineering services. NVision was tasked with reverse-engineering a bottle and lid so that the manufacturer could then perform computer simulations to pinpoint the source of the problems.

NVision technicians decided that CT inspection offered the most accurate solution for solving the sealing problem. CT scanning is a non-destructive process that uses x-ray equipment and a detector array to produce computerized representations of both an object’s internal and external components. With CT scanning, design and manufacturing requirements for components are quickly confirmed with the highest degree of accuracy – from 0 .0002 inches / 0.005 mm. The dataset produced from the scan is an STL (stereo lithography) file, which is opened in specialized software and can be used for rapid part-to-part inspection, part-to-CAD inspection, or reverse engineering to a native CAD file. “CT scanning is typically utilized when a customer’s needs exceed the capabilities of laser scanning. It’s particularly useful for inspecting the internal geometry of transparent materials – such as glass bottles – and discovering flaws that might not be detected by other forms of scanning,” said Steve Kersen, VP of Sales and Marketing at NVision. CT scan of bottle top with a proper seal

NVision technicians first CT-scanned a regular-size bottle and lid separately, then scanned the assembled bottle and lid, and performed an inspection of sealing surfaces. In less than one day, the scanning and inspection were completed and the sealing surfaces on the assembled bottle and lid were confirmed to be working. “Another reason why CT scanning is ideal for inspecting sealing surfaces is that bottle leakage involves a natural contrast agent – air – that may not be seen in other scanning but which stands out in a CT computerized image. In this case, if the surfaces had not been sealing properly we would have seen the air as a distinctly black color on the CT image, indicating where seepage was occurring,” said Kersen.

After NVision confirmed that the bottle and lid surfaces were sealing correctly, the manufacturer was able to utilize the CAD information from the CT scanning to find, isolate, and resolve the sealing issues of the larger bottles through re-design.

NVision was also recently asked to use its CT inspection technology to aid a major manufacturer with a project involving composite insulation. The pore size of the composite material was critical. There was a maximum size the pores could be to meet quality standards. “This was another project ideal for CT scanning, which can clearly identify internal porosity and cracks where 2D x-rays show inconclusive or no results,” said Kersen. “In addition, because internal components can also be scanned, we didn’t need to cut up the material to locate internal porosity.”

NVision technicians were able to detect density changes greater than .25 g/cc from the base material. With scan oversampling, voids as small as 1/10 the scan resolution could be found and quantified.

NVision met the manufacturer’s tight inspection deadline, scanning and returning the material within two days. The results showed that all pores in the composite insulation were significantly smaller than the maximum allowed tolerance and the project was green-lighted to proceed. “Continued improvements in processing speed, coupled with the capability to find and identify small details that would be undetectable to other forms of scanning, are moving CT scanning to the forefront of essential technologies for industrial inspection,” said Kersen.
