Parallel Sides for Clamping and Bridging
Our U shaped copper busbar has a cross-section shaped like the letter U. Two parallel sides connect through a flat bottom. This shape solves a common installation challenge. It can clamp onto a busbar or make a bridge connection. The two parallel sides touch two conductive surfaces simultaneously. This doubles the contact area compared to a single flat bar. More contact area means lower resistance and less heating. Our team focuses on the parallelism of the two sides. If the sides are not parallel, the piece will not fit. We use special fixtures during bending to maintain parallelism. Every piece gets checked for width and side alignment.
Parallelism Control and Dimensional Accuracy
Our bending fixtures hold the material securely during forming. This prevents side-to-side variation. The fixtures also control the distance between sides. This dimension is critical for proper fit. We measure the width and side alignment on every piece. Any deviation beyond tolerance triggers a process review. The bend quality also matters. The bottom corner must have the correct radius. Too tight and the material may crack. Too loose and the shape may not fit. Our workers have developed a reliable process for U-shaped bends. They adjust the settings based on material thickness. The result is consistent quality across all orders.
