Winning new customers for its products costs a lot of money today. This makes it all the more attractive for companies to retain existing customers – and make them happy. Nothing convinces customers more than reliable quality. And vosla ensures this in the production of its lamps in a special way: creative, uncompromising and with “zero-defect tolerance”.
From a very short distance two gas jets with a temperature of more than 1400 degrees Celsius shoot at the rapidly rotating glass cylinder. It glows white and then tapers down to a diameter of 3.0 mm within 0.3 seconds – as though tied by an invisible hand. Metal arms seize him and transport him to the next level of production at lightning speed.
Here, the glass cylinder merges inseparably with its future inner life: a molybdenum frame, a precisely shaped wire construction and the helix fixed to it. Now a machine pumps through the upper, still open capillary oxygen from the glass bulb. Foreplay for the now following halogen gas filling: The gas is frozen in the ice-cold nitrogen bath and liquefied. So it can not escape, and the upper capillary can be airtight merge.
But cold and extreme heat put the glass under tension. Therefore, the entire burner is now “annealed”: After a warm-up phase, a precisely timed cooling takes place and the next production step – because, of course, the forming and filling of the glass cylinders is only one of many. Individual parts arise on a total of 5 burner and 6 processing lines.
