About Us

About Us

In 2001, the year of our foundation by two brothers in a small workshop, we provided outsourced services such as deburring and polishing.

In our research, we discovered that the methods to fill the casting cavities emerging during the casting of parts produced by means of casting and injection are deficient. In 2002, we expanded our workshop by incorporating an impregnation (resin impregnation) facility and entered the industry sector.

In the light of the technical training our executives received in Switzerland and their experiences, we started service and production in a confined space of 800 m2 after adding CNC processing machinery to our machine park in 2013.

We increased the capital of our growing company and continued to improve our machine park and provide various services to meet the needs of the sector. In our company which also provides mass production (transfer machinery) in addition to outsourced services, we incorporated processes of sandblasting and vibration, extended our area of production and provided more employment.

Today, we provide our services with the technological machine parks installed at our 1000m2 facility in Tuzla, Orhanlı.
