Quickly identify internal voids that could lead to strength and durability issues.

Porosity Analysis offers a comprehensive solution to visualizing pores and voids in your parts. Part of Voyager’s Integrity Analysis module, it enables users to quickly identify internal pitting that might lead to strength and durability issues. Engineering teams can automatically diagnose internal flaws to improve their manufacturing and optimize their quality control and assurance processes.

Analyze critical pores to prevent malfunctions

Problem: Internal pores can be difficult to spot without destructive testing. Here a Medical Hose Barb has a 20 mm pore that weakens the essential component and can lead to cracks and other failures, but would be missed by the naked eye without destructive testing. 

Solution: Users can adjust resolutions and thresholds to their inspection requirements and desired level of detail. Once parameters are set and the Porosity workflow is run, users can easily view, segment, download, and share data.

Quantify pitting to maintain structural integrity

Problem: Parts that may initially appear to have been manufactured to meet specifications could conceal voids that can have detrimental effects on the material's structural integrity, appearance, or functionality. In the food industry, voids can trap biological material leading to contamination. In structural parts, these pores can concentrate stress and become points of early failure. In ultrasonic welding, these are indicators of a poor or failing weld.

Solution: Porosity Analysis allows Voyager users to identify small, localized depressions or cavities within a manufactured part before shipped to a customer.

Improve process parameters in manufacturing

Problem: For plastic parts that are injection molded, voids can occur in threading, valves, or snap features, which compromises the load bearing capacity. When molding resin is not adequately dehydrated and pressurized, vaporized moisture can form pores and internal imperfections.

Solution: Porosity Analysis effectively pinpoints, visualizes, and quantifies the voids, enabling engineers to identify when process parameters need to be modified or dialed in.

Minimize recalls due to voids in Consumer Packaged Goods (CPG)

Problem: End consumers are vocal and demonstrative when their favorite and essential products do not perform as expected. Pores can also lead to unattractive as well as malfunctioning products. Recalls and other costly legal issues can arise when each part is not properly inspected before being shipped.

Solution: With Voyager’s newly expanded Integrity Analysis module, even the smallest pore is detectable to accelerate your quality and assurance processes.
