Metal casting, the process of pouring metal in molten form into a mold to create a casted part, is used in a variety of applications; from art to industrial parts. Because of the need for complete precision during the entire casting process, quality control is a must. Only through a visual inspection of the internal passageways can professionals be sure that there are no defects or foreign object debris (FOD) that could cause problems down the road. That is why using a video borescope during the casting process, and final inspection can save companies time and money.

Video borescopes are utilized for a significant amount of inspections during the casting process. Over the next few weeks, RF System Lab is going to provide an in-depth look into how videoscopes like the VJ-Advance articulating video borescope instill confidence in numerous casting quality checks.

We’re starting off this blog series with coating inspections.

Once a part is casted, it sometimes needs a secondary polishing, which is completed by precise methods such as electropolishing. These secondary polishings, made of thin films of material, finish off rough passageways and add protection to the surface of parts. This procedure is crucial for many industrial uses – especially when the parts are being used for food and drug industries, where a smooth surface free of FOD is essential in order to keep the final products clean and pure.

That being said, internally inspecting coated parts is a must in order to confidently confirm that they are free of burrs, cracks, drippage, and even corrosion further down the line. Video borescopes with extremely thin insertion tube diameters, like the 2.8mm VJ-Advance video borescope, are the ideal tool to inspect these coatings. Videoscopes enable NDT professionals to easily observe and take high-resolution photographic evidence of the internal condition of parts, which is a necessity when confirming condition. Quality checks with a video borescope greatly reduce the risk of defects in the coating of a casted part, which also reduces overall expenses by preventing contamination and cracking in coating.
