Q: What approvals are needed for non-destructive testing?

We are certified and approved by Nadcap for NonDestructive Testing. This is a requirement to be able to process aerospace products. Note that many customers will have their own approval process outside of Nadcap. It is best to check with the OEM (original equipment manufacturer) before placing an order.

Q: How large of a part can I have processed?

We can accommodate nearly any size of part using various methods of penetrant inspection. We offer methods A, B, and C; each brings its own requirements. These may include various requirements for dryers, types of dyes, and types of developers. We have custom built our equipment to meet the needs of our customers for processing large products.

Q: Do you offer other types of testing beyond dye penetrant?

No. Various other types of non-destructive testing exist such as mag particle or ultrasonic testing. We only offer liquid dye penetrant testing at this time.

Q: How long does it take to for NDT?

We pride ourselves on fast turnaround times and multi-process convenience. Depending on the results, we typically process all parts through NDT in under a week. Then by using further processing capabilities with Pilkington, you can have heat treatment, NDT, chemical treatment, and finishing all done under one roof. This offers a huge time savings.
