SEC 01 / PROFILE The Company
Since 2011, One Product
RUIAN RUIDI AUTO PARTS CO., LTD was established in 2011 in Rui'an, Zhejiang — the heart of China's auto-parts industry. We mainly produce dual mass flywheels (DMF) for passenger cars and pickups.
Our catalog covers DMF assemblies for European cars, Korean cars and Chinese cars. We hold complete design and development capabilities in-house: mold opening, stamping, heat treatment, assembly inspection, dynamic balance testing, durability testing, grease detection and road testing.
SEC 02 / PROCESS ROUTE Our Advantage
Eight Steps,
Zero Outsourcing
The full DMF development route runs inside our own plant — every unit is traceable from raw stamping to road test.
