For over 35 years , HoKa GmbH has been your partner for plastic ventilation moldings. All plastic molded parts are manufactured by us according to DIN EN ISO 9001. Not only molded parts such as Bends, Damper valves, Reducers, Double sockets and T-pieces, but also ventilation pipes  and exhaust pipes you get from us from a single source. 

Everything began in the mid-eighties in Karl-Josef-Schäfer's home kitchen: To manufacture a bend for a ventilation made of plastic, he heated a PVC tube in the oven and then formed it with a bicycle tube. The result was impressive, and so Karl-Josef proudly demonstrated it to his former boss Horst Severyns. Both men quickly realized the necessity of founding a company which would develop machines for the production of bends - this was foundation date of HoKa (Horst & Karl).

The developed blow pipe procedure was patented and is the central component of HoKa's manufacturing process to date. Today, the company is equipped with the latest in technology and markets its ventilation fittings of thermoplastics throughout the world.
