In-Depth Partnership Stories: How We Create Value for Our Partners
A Classic Legacy: A Trusted Partnership with Ford for Over 20 Years
Customer Challenge: To provide highly consistent and durable chassis damping components for multiple classic fuel-powered models that could withstand long-term, rigorous testing.
Our Role & Contribution: Since becoming a supplier to JMC Ford in 1999, we have done more than just manufacture to print. We get deeply involved in their development process, applying our profound understanding of rubber materials and bonding processes to the continuous optimization of their products. This ensures that every bushing and mount we deliver perfectly meets Ford’s strict global quality and durability standards.
Partnership Outcome: Over two decades of stable collaboration with zero major quality incidents. We have become a stable, reliable, and trustworthy part of Ford’s supply chain.


Innovating in Sync: Writing the Next Chapter in New Energy with BYD
Customer Challenge: To develop damping solutions for leading new energy vehicles that could meet brand-new requirements for extreme quietness and lightweighting.
Our Role & Contribution: As a technical partner to BYD, we get involved in the collaboration from the project’s earliest stages. We leverage our deep expertise in core rubber formulas and our CAE simulation and analysis capabilities to provide customized damping solutions for many of their new energy models, successfully tackling new NVH challenges like suppressing high-frequency motor noise.
Partnership Outcome: We helped BYD successfully create multiple bestselling models with an exceptionally quiet and comfortable driving experience, which have won high recognition in the market.
