Raydiance pioneered the application of femtosecond laser technology for production of gasoline direct injection (GDi) fuel injectors. We deliver ready-to-integrate manufacturing solutions for precision hole drilling with unmatched part-to-part consistency and lowest cost per part.
GDi technologies make powerful engines possible, emitting up to 30% less greenhouse gases and other pollutants while maintaining engine performance. Many teams on the Formula 1 and Indy Racing Circuits have turned to GDi. A growing number of passenger car models are available today, complying with European and U.S. emissions standards (EU6, US Tier III).
The key to successful use of GDi technology is tight control over the nozzle hole size that impacts the spray pattern of fuel and fuel droplet distribution into the combustion chamber.
Unlike Electric Discharge Machining (EDM), the Raydiance R-Drill™ all-laser solution delivers unmatched part-to-part consistency as measured by flow consistency and spray pattern analysis. Raydiance’s customers have used the R-Drill to produce over 6.8 million GDi nozzles to date. Our expertise enables customers to pioneer radical new GDi concepts and designs.
The R-Drill process creates square holes, elliptical holes, and highly customizable shapes, patterns and tapers proprietary to global auto parts producers. Prototyping of these new concepts can now be completed in a matter of days versus the months it can take with EDM methods.
