Founded on January 1, 1993 with just three machines in a 100m² workshop, ZLR was founded on the ethos of 'Honest Work, Family-Built' championed by Yuezhong Wang from day one. The Wang family's hands-on approach prioritized two non-negotiables: premium craftsmanship and customer-centric service.
1993-2008: Forging Legacy Through Adversity
Within the first five years, the fledgling enterprise faced its ultimate test when Mr. Wang's father succumbed to cancer after exhaustive treatment efforts. Turning grief into determination, the founder stayed true to his father's vision, achieving key milestones:
• 1999: Established in-house material R&D lab
• 2003: Pioneered digital sales in China's early e-commerce era
• 2008: Expanded to 1,500m² facility in Zhejiang
2012-Present: Institutionalizing Excellence
The second-generation leadership under Andong Wang (joined 2016 after completing his studies in the US.) propelled strategic modernization:
• 2012: Earned ISO 9001 certification
• 2016: Launched plastics division with 15% annual capacity growth
• 2024: Achieved IATF 16949 for automotive-grade manufacturing
After 30 years, five locations, and three generations of hard work, ZLR successfully maintained the core values established in 1993 with a full commitment to employees, customers, and the community.
