Who We Are

Nel PreTech Corporation is an A2LA accredited dimensional inspection laboratory providing dimensional inspection services on most first article manufactured parts.

Nel PreTech established in May of 1993.

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 technicians, 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. Our CT specialists 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.
Engineering
Our mechanical engineers don’t just make measurements to your print. They understand the way your part works, how it was designed, the forces applied to it, and how it fits within the context of an assembly or gage. This gives us a unique advantage when it comes to measurement and the interpretation of data. This allows our engineers to supply the most useful data possible to our customers, whether they are machinists, designers, or QC professionals.
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.
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 we need to ALWAYS have a CMM programmer available for standard first article inspections, gage r&r, or capability studies.
