Internal Inspection of Castings

Internal inspection of metal castings

Fresh metal castings often have internal passages, holes, and chambers that can contain a variety of defects that are difficult or impossible to see with the naked eye. The inspect these areas, quality control personnel require a Remote Visual Inspection (RVI) device. Defects found within metal castings may include:

  • Porosity and voids caused by trapped gas or shrinkage in the cooling process,
  • Cracks that may have formed due to thermal stress,
  • Trapped non-metallic foreign material,
  • Burrs and flash that may affect the parts function and fit
  • Surface finish defects that may affect function, e.g. fluid or airflow

The metal casting may require post machining or post repair verification as well as a thorough inspection before a costly pour ensuring they are free of debris.

Using Hawkeye borescopes for internal casting inspections

The Hawkeye borescopes provide the best choice of products, for a specific application depending on the casting’s geometry.

Rigid Borescopes: The Pro Hardy is ideal for straight line inspection paths offering superior image clarity and are very durable; suitable for factory use.

Flexible Borescopes: The Pro-Flexible is a flexible borescope available in different diameters with 4-way articulation; durable with very bright illumination. 

Video Borescopes: The Q2 Video Borescope is one of the most advanced systems and feature miniature camera(s) at the tip transmitting live video to a screen with the ability to capture and store images. 

Borescopes are part of the range of non-destructive testing (NDT) products that allow internal inspection of castings without damage or disassembly and provide a fast and direct way to visually inspect a metal casting.

Don’t let hidden defects compromise your quality. Contact us today for a consultation and a live demonstration to see how our Hawkeye non-destructive inspection tools can secure the integrity of your castings.

We need suppliers that can go the extra mile in looking specifically at our application and then providing a suitable and sometimes bespoke solution, and this is where Optimax have really made a difference

John Harris, Director, Nevo Developments

Optimax have an extensive product range that was very attractive to us. They took the time to understand my requirements and align a solution that fitted into my manufacturing processes. They were very knowledgeable and friendly, I found the virtual demonstration extremely helpful. The outcome of the project has been very successful and performs above expectations. I would definitely recommend Optimax.
