Surfaces as if polished by hand In the field of high-quality jewelry and watches, the most stringent demands are placed on surface quality. OTEC has amassed a wealth or experience with intricate working parts and supplies virtually all top manufacturers throughout the world with innovative machines bearing the seal "made in Germany". The very best surface quality and the absolute reliability of the processes and advanced technologies used ensure OTEC's leading position in this sector. The right choice of media and machine technology enables OTEC's machines to achieve a surface quality that is equivalent to hand polishing. OTEC offers you the expertise needed to ensure the best results when finishing stainless steel, platinum, gold or ceramic materials.
The usage of jewellery goes back to the beginnings of humankind. And the development and manufacturing of devices for jewellery making and jewellery cleaning also goes back to the founding years of Elma.Shiny metal or bright and colourful precious stones - fascinating materials, which are often crafted into small artworks, using great skill and artistic talent. What is particularly important here is that every little stone fits into its mount, and all residues of the manufacturing process are cleaned off, so that the gem can shine.
Fastly developing 3D printing technology also provides different opportunities for jewellery manufacturers which makes it possible to produce some kind of jewellery much cheaper and faster which was not possible with the traditional production methods. 3D printing technology is changing the traditional production method. In traditional way, a master mold has to be produced which is followed by rubber mold making and wax injection processes which is really costly. 3D technology gives the advantage to make directly casting and eliminates the costly operation of the master mold making process. With the foresight that 3D printing will replace the wax injection in the near future, Uniway Optronix is developing 3D printers for different sized manufacturers around the world with high speed , printing quality and precision specifications. Uniway 3D printers is strengthening its leader position worldwide about speed, surface quality, precision of weight and dimension and productivity with new developments.
For over 60 years at the forefront in the electronic fusion of metals for jewelry.We have an articulated range of melting machines with process technologies differentiated according to the raw material to be treated and the desired final product to allow the operator to obtain a qualitatively superior jewel in the constant objective of containing costs and paying attention to environmental problems. The electronic induction casting machine is the qualifying machine of the entire casting process, we are in any case able to propose the complete line of jewel creation from the rubber model to the water cleaning cabin.
