Custom Specimens and Mock-Ups

For specific NDE training, procedure development, personnel training and qualification, specialist training and performance demonstration.

Our custom specimens are manufactured to your design, our team will work with you to make your concept become reality. We will use precision machining and our in-house expertise to create your chosen part, giving you a flawed specimen which suits your needs exactly.

This could be to simulate worst-case flaws which can occur during part construction or to replicate particular in-service flaws as seen in the field.
