The production of our tuning forks is based on more than 130 years of experience in this area of expertise.  We attach great importance to a high level of in-house production depth.  Most of our component parts  are produced in-house so that we can  guarantee a constantly high quality and longevity of our products.
We only use carefully selected,  first-class materials. All our tuning forks  are accurately cut and drilled out of massive blocks of metal using state-of-the-art CNC machines.
At a very early point in our production process we start measuring the tone pitch of our tuning forks, which enables us to continuously correct and fine-tune the  pitch in the further production process. By this, the frequency deviation of our tuning forks can be reduced to a minimum.
To this day, the final precision-tuning of our products is manual work. Of course in this process we are supported by state-of-the-art measuring technology. Each and every tuning-fork that leaves our premises has undergone a very careful final inspection and testing.
