SINCO was founded in 1973 by Mr. Stanko Šinko (Gründer) as a tool shop under the name SINKO Alati, located in Jesenice na Dolenjskem, Slovenia. Initially, the company focused on the design and production of molds for plastic injection, primarily serving companies in the ex-Yugoslavia region.

In 1980, the company was renamed to Formtehnik. That same year, it acquired its first plastic injection molding machine, marking the start of its journey into serial plastic production—a business that grew rapidly over the following decades. The addition of the plastic injection department significantly enhanced SINCO’s expertise and experience in mold production, enabling a shift toward high-precision, challenging tools with a new focus largely on the German automotive sector.

With years of experience in mold production, SINCO has developed numerous technical solutions aimed at process optimization, focusing on manufacturing flexibility and the standardization of operations. By delivering hundreds of process optimization solutions, SINCO successfully addressed two major challenges that emerged in the European Mold & Die sector after 2000: the shortage of skilled labor through standardization and the increasing competitive pressure from Eastern markets by enhancing productivity and quality.

Since 2020, the company has effectively started tackling a new challenge by utilizing its longstanding expertise and started supplying the global market with clamping solutions designed for industries that demand flexibility and efficiency in workpiece handling, under the original name SINCO.
