Hochmuth explains: “It starts when the luminaires enter the frame. There is a one hundred percent check for weld strength testing. Then the geometry test up to a hundredth of a millimeter with hundred percent good-bad control. But even in the first step only geometrically flawless semi-finished product reaches the next processing step. ”
Monitors with microscope images hang everywhere
The giant clock keeps ticking. She turns, grabs and interlocks, she kicks in, sits up, she sweats, heats, squeezes, pinches and pumps, and she adjusts. All this with an accuracy that no clockwork ever achieved. And at each of these points is measured. There are measuring monitors everywhere. They show strongly magnified live-microscopic photos, snapshots of crucial moments of each individual process step.
No samples are measured here. With the tremendous speed dictated by the 4,000-meter cycle, a sophisticated and custom-developed system measures every single component that runs off the production line – in real time. From the filament to the frame to the glass body, not a single element remains unrivaled. More than 20 of these measuring points will be at the end. Before, no lamp leaves the factory.
vosla is a supplier to the automotive industry. Only in the aircraft industry are the quality requirements even stricter. And at vosla itself. Hochmuth is by no means overburdened with these requirements. His team surpasses the claims confidently – namely ten times.
“The industry sets tight tolerances. Such tolerance is, let’s say, plus-minus two tenths. Let’s assume that during production the tolerance has been exceeded or undershot by one hundredth. Then you have 0.21 now. As the plant says: The product falls out. No customer would see the difference, even you, not even with any tools. That can only be this automatic geometry check. That’s why we say: one-hundredth of a millimeter decides on good and bad. Within such tolerances we move. ”
