It's also about understanding your customer and establishing expectations right from the start.

NPC has always been a family business. Brothers Dave and Greg Nelson endeavored to build a reputation for detailed, high-quality inspection and thorough reporting. Both have a passion for mathematics and problem solving, which are at the core of any good metrology. “Everyone we hire must possess this same passion, as ultimately it reflects in the work we provide to our customers.” says Greg Nelson (Owner-Operations Manager).  Dave, together with his wife Jennifer and brother Greg, are proud of the long history, the people who have worked for them over the years, and the reputation for high-quality metrology they achieved.

How we are different

Industrial CT Scanning
Our industrial CT specialists aren’t just tech’s, they’re physicists. They understand the science behind x-rays, how they behave, and how they interact with parts of different material types and densities. This gives them a unique perspective when it comes to obtaining the BEST scans possible and capturing part features that otherwise would not be picked up by an average scan. Because our CT specialists are highly qualified, they also understand statistical variability and data trends. This is key when performing the final data analysis. The same individual stays with the project from the start of the scan until the final data interrogation.

Design
Our designers are also metrologists. They understand 3D scanning and the uncertainties involved in data capture. This gives us the ability to obtain metrology grade scans where other scanning service providers cannot. This level of accuracy is crucial to providing high quality reverse-engineered CAD models and blueprints. Our designers are highly experienced and have provided services for many different industries. These industries include but are not limited to: medical, automotive, defense, and food packaging. You name it, we’ve done it!
Programming
Although each one of our staff members has unique talents, we are all highly skilled CMM programmers. This is the common thread or baseline that runs through our entire organization. This gives us the flexibility that we need to ALWAYS have a CMM programmer available for standard first article inspections, gage r&r, or capability studies.

Industrial CT Scanning
Excellent tool for helping customers detect part flaws, determine the cause of a product failure, reassemble an item, or reverse-engineer a part.
NPC offers structured light 3D scanning in the form of our newly acquired ATOS Q blue light scanner. This is an optical, non-contact technology that projects a fringe pattern across
Common Uses
  • Flaw Detection
  • Failure Analysis
  • Assembly Accuracy
  • Reverse Engineering Applications
  • Metrology

The Difference

Nel PreTech Corporation is the first A2LA accredited lab in the U.S. for industrial CT services. We operate the Metrotom 800 and 1500 computed tomography machines created by Carl Zeiss Corporation, a global leader and manufacturer of precision-measuring instruments. Beyond the scan, we offer post-scan engineering and measurement services as required.
NPC uses CT scanning technology to form 3D models that allow the user to examine the interior and exterior of the item being scanned.
