Perfect Surface Worldwide

CThe great success of OTEC’s machine technology is at least in part due to a revolution in areas previously dominated by manual finishing processes. OTEC enables a perfect surface finish to be achieved through a mechanized process – with greater precision and more consistent quality than can be obtained through hand polishing.



OTEC Präzisionsfinish GmbH was founded in 1996 in Straubenhardt near Pforzheim in the Southern German state of Baden-Württemberg. Over the past 20 years, OTEC has grown from a small manufacturer of polishing machines for the local jewelry and watchmaking industry to become a truly global player.






New way of finishing

1st Class German Casting Technology, the trusted name in the Jewelry world.


The great success of OTEC’s machine technology is at least in part due to a revolution in areas previously dominated by manual finishing processes. OTEC enables a perfect surface finish to be achieved through a mechanized process – with greater precision and more consistent quality than can be obtained through hand polishing. Such smooth surfaces, defined edge rounding and perfect, mirror-finish surfaces have become more important than ever in many branches of industry. This process enables friction to be reduced which in turn saves energy or dramatically increases the service life of tools. In order to meet the most stringent requirements of its customers.
