|From welder to hidden champion|
After the war, the father of the current managing director founded the first company. The trained welder built fire trucks, wagons, and potato peeling machines. Hirsch painted handles for the garden tool manufacturer Wolf PVS. Then a manufacturer of teacups came up with the idea of painting the handles. For this there was a huge tub in which up to 400,000 glasses could have been painted. The cleaning of these tubs was laborious and Hirsch began to varnish the paints with spray guns. 35 years ago, the founder built his own fully automatic spraying machines, as there was no plant constructor for them. Today, Hirsch produces up to 200,000 glasses a day in its two factories with seven ovens.
Silicate paints chemically create a layer of glass. Like glass itself, they contain silicon. Colorants are embedded in the liquid substance-- the silicon dioxide molecules. As soon as a thin layer of color is applied to the glass, the air humidity ensures that the molecules crosslink to form a gel. This finally becomes solid. The result is a glass-like structure. And the colour layer bonds with the underlying glass. After application, the paint is baked in the oven between 140 and 200 degrees for about 20 minutes. This creates a chemical bond with the glass surface. Today, such paints are solvent-free and non-toxic.
|Cloud of Things|
The Cloud of Things is Telekom’s IoT cloud platform, which customers can use to remotely monitor, manage and control networked devices and machines. The Cloud of Things collects and stores the sensor data and status messages of all connected devices, evaluates them and prepares them clearly for the user, who can display them via the Internet. The collected information is evaluated approximately in real time. If limit values for individual sensors or complex events are exceeded, a message is triggered. Maintenance technicians can then see the reason for the error message via the online user interface and react as quickly as possible.
