Tube Fabrication and Bending Services
Tube fabrication is the process of bending a tube to a specified shape that meets customer functional and dimensional design specifications. We offer Laser Tube Cutting, Robotic Welding and Assembly.
This is particularly helpful in achieving prototyping changes; production flexibility and repeatability; higher overall quality; reduced costs and faster turnaround.
Value-Added Engineering
From materials to product design and development, our engineering group focuses on production processes that will optimize efficiency and ensure quality, on-time delivery and pricing parameters. For new programs, we routinely bring together dedicated resources along with formal APQP reviews.
