PEM Technologies

Precise Electrochemical Machining (PEM) is a powerful, non-contact metal shaping process that pairs a PEM Machine with an electrolyte processing unit, power generator, and operator control station. Using electric current and an oscillating tool bathed in a conductive electrolyte (salt water), PEM dissolves metal by liquefaction.



For more than 30 years, the name SITEC has been standing for distinct technological orientation as well as high innovation power in mechanical and plant engineering as well as series production of sub-assemblies and components. Our strengths include the optimization of technological sequences and reacting flexibly to the challenges of a dynamic market.


SST Americas

Founded in early 2005, SST targets the middle-market stamping industry as the exclusive distributor of INGYU products in the Americas. In addition, SST offers a full compliment of press service and spare parts coverage. The line of INGYU products includes the Apex, Civic, IHD and the Saga Series.
