Producing Geometry You Can Trust
QC provided an engineer for our project who did a great job of collecting the dimensional data for the parts to be reverse engineered, creating the CAD models, and producing prints for manufacturing. He kept in regular contact with me throughout the project, allowing us to quickly resolve issues as they arose. He was also very responsive when asked to make changes to the prints. Overall, a superior job.

Precisely Mapping Sinks and Shrink
Localized shrink in a cast or molded component is very accurately defined with the right laser scanning equipment. This method is often used to troubleshoot tooling by developing surfaces of the sink area and using the new CAD geometry to modify the tooling insert.
On small parts, the organic-shaped sink can be replicated to 2 or 3 ten-thousandths of an inch. Miniature sinks can be replicated to less than a micron.
This is a very precise method of obtaining results when qualifying tooling. A typical turn-time to receive new CAD data is 24-48 hours, allowing inserts to be accurately modified quickly.
The process has been successfully applied to sealing surfaces, bearing areas, and any application where the shape is critical and when wall thickness or process modifications cannot adequately compensate for sinks.
