Our Products Fuel Injection Technology


As a medium-sized special machine manufacturer, Sonplas has been contributing to ever more efficient injection systems with numerous innovative and patented solutions since its foundation in 1993. The typical processes such as micro adjustment, laser welding, calibration and flow testing with AFM, valve closing time measurement, leak testing, beam image testing, system testing or shot-to-shot testing are mainly used in the automotive, aerospace, marine and stationary sectors – both as R&D laboratory systems and as highly automated production lines.

Through early involvement in the product development process, our development departments always find the optimum solution for each individual customer requirement.

Today, Sonplas is a leading manufacturer of assembly and testing systems – also thanks to worldwide service: Worldwide, several Sonplas injectors come off the production line every second, and every second high-pressure gasoline pump also runs a Sonplas end-of-line test.
