Comprehensive testing
for high-quality serial production


Several automatic or manual tests and inspections are carried out. To secure the quality of our products, 100% of our coils & linear drives are tested with high-voltage, inductance, resistance, magnetic field direction, water pressure and flow testing. Complex mechanical parts are tested in an early stage on our automated 3D measuring machine.

Serial production

For serial production SFC has its own production facility in Cluj-Napoca, Romania. With highly skilled and trained people, the Cluj factory delivers coils & linear drive products in quantities from 10 to 10,000 units a year.
SFC Cluj strives to be one of the most flexible coils suppliers in the industry with an ability to manage rapid design changes, schedule adjustments and use inventory management programs to achieve best-in-class cost and capacity management.
SFC has dedicated in-house teams to manage all aspects of service, engineering and manufacturing requests for a fast and accurate response to customer requests.
