It all began in the mid-eighties in Karl-Josef Schäfer's kitchen at home: to make a pipe bend for plastic ventilation, he heated a PVC pipe in the oven and then deformed it with a bicycle tube.
The result was impressive and Karl-Josef proudly demonstrated it to his boss at the time, Horst Severyns. It quickly became clear that the two wanted to found a company that would develop machines for the production of pipe bends - the birth of HoKa ( Ho rst & Karl ).
The blowpipe process that was developed was patented and is still a central part of HoKa's manufacturing process today. Today, the company is equipped with the latest technology and sells molded plastic ventilation parts worldwide.
