Sinop had to invest in new machines in order to satisfy the stringent requirements of the cooperation partners. The demand for laser welding work grew particularly quickly. The technology became obligatory for their own products. For example, in the case of Soda Stream, a real sales hit, which is a device that prepares soda water for gastronomy. High-quality weld seams are an absolute must in its piping system, otherwise germs could start to form along the protruding edges. "That is only possible with the laser," confirms Kriz. The welding process is only one of many sheet metal processing steps in the product's production chain. The draining rack must be deburred, the housing must be folded and the individual parts of the tap device must be cut. The majority of Sinop products have such a high vertical range of manufacture. That has a downside. "In recent years, it has become increasingly difficult to keep an overview in production control," says Kriz.
