RF System Lab’s Video Borescopes for the Casting Industry series continues this week; starting with residue reduction. We’ve previously provided insight on coating inspections, weld inspections, and slag inspections, and also want to provide a short metal casting process recap:

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 absolutely sure that there are no defects or foreign object debris (FOD) that could cause problems down the road.

Overview of residue:
Residue is, put simply, unwanted material left behind during the casting process. Residue can be made of liquid non-metallic components, which are an outcome of alloying and oxidation. For this reason, the reduction of residue is a must; it can quickly contaminate any liquids flowing through internal passageways.

Contamination is obviously something that any company works extremely hard to avoid. Video borescopes are an ideal tool for internally inspecting critical passageways and other parts of casted materials to check for residue of any kind. Videoscopes have time-stamped camera and video capture functions, which gives quality control technicians the ability to document the exact location, date, and time of the residue discovered. Quality Checks with a video borescope greatly reduce the quantity of new metallic residue components and give companies confidence that their finished casted parts are free of foreign object debris (FOD).

The next edition of our Video Borescopes for the Casting Industry series will be on the blog soon! In the meantime, you can find out more about how the VJ-Advance video borescope is the perfect tool for reducing residue in casted parts by visiting the RF System Lab website or by calling (231) 943-1171.
