Quality / Metrology Capabilities

In 2017, FSI made the decision to strengthen and reinforce our Quality program. Investing in a (coordinate measuring machine) and 3D imaging device to solve dimensional metrology problems. This decision allows us to not only perform in process Quality Control inspections but also reverse engineering of components that would take hours of hand measurements to validate and complete.

Technology from the portable CMM permits high-precision 3D measurement, imaging and comparison of parts and compound structures within production and quality assurance processes. The Portable CMM is used for inspecting components and assemblies, production planning, documenting small and large volume spaces or structures in 3D, and more. This measurement technology allows our company to maximize efficiencies and improve processes. This addition of technology sets FSI apart from other manufacturers in becoming a resource to our customers not just a supplier.

FSI as a company has company recognized that there is a need for collaborative partnerships with our customers. FSI works closely with our customers to provide onsite services to assist with Engineering and Quality. We strive to build and strengthen our relationships by better understanding the design intent and application of the end product. This helps drive product repeatability and throughput.

Gas Gun Project

Great job from all involved to keep on task!!!

Latest redesign / reverse engineered project completed at FSI. Customer request to take a cast part that did not have a existing TDP.   Reverse Engineer the cast sample using our FARO arm with laser scanning capabilities we were able to provide the customer with (3) option to produce the final assembly. One week sooner than project deadline. Option 1 source a cast part – pricey and long lead times. Option 2 machine out of billet- long machine times due to multiple set ups and contour machining. Option 3 Weldment- breaking down the part into (4) piece part that could be welded together in complete assembly.

From cast part to weldment within the quoted time frame!
