6%+ on R&D
Dongtan has always seen quality as the management foundation, investing over 6% of annual revenue in R&D.
Stage-Gated Development Protocol
Implemented a structured supplier integration protocol embedded within the APQP framework. This leverages joint FMEA workshops, co-development of critical performance parameters (e.g., material specs, fatigue life targets), and real-time digital thread connectivity for seamless data exchange (CAD, test results, quality metrics).
APQP Management
Established a standardized APQP (Advanced Product Quality Planning) management process, which runs through all project development, to ensures standardization, effectiveness, professionalism, and reliability of the development
FEMA Management
Continuous FMEA library management with knowledge-based repositories, leveraging accumulated domain-specific suspension expertise to proactively mitigate design risks and elevate development success rates through statistically validated patterns.
Supply Management
Established a proactive supplier collaboration framework. Through joint development of critical performance parameters (e.g., material specs, fatigue life targets), shared digital platforms for real-time data visibility (CAD, quality metrics).
R&D TEAM
Zhong Xiang Dongtan has a group of 26 professional, stable, and experienced R&D staffs; continuously investing in laboratory and R&D to ensure company can offer rapid and efficient solutions for customers.
