May 10, 2026 — Hubei Zhengye Factory, a professional rubber material manufacturing factory based in Hubei, China, held its grand 5th anniversary celebration and full-staff team-building activity. As the core upstream rubber material production base serving S&L and KAL, the factory has supported stable and standardized raw material manufacturing for both brands over the past five years. Rooted in China’s Hubei manufacturing hub, Zhengye Factory acts as a crucial quality pillar for S&L’s global product layout. This five-year milestone recognizes consistent manufacturing excellence, laying a solid foundation for S&L’s continuous quality upgrading and reliable global product delivery.

For global B2B custom desk accessory brands, stable and premium product quality stems from strict raw material source control. Backed by the professional manufacturing strength of KAL’s vertical supply chain system, S&L shares the high-quality upstream resources of Hubei Zhengye Factory. Different from brands that rely on unstable third-party outsourcing, S&L benefits from the factory’s in-house full-process production, including independent rubber formula R&D, precise raw material proportioning, standardized batch production and rigorous performance testing. This localized whole-process quality management effectively avoids quality fluctuations from external suppliers, greatly improving the durability, anti-slip performance and environmental adaptability of S&L custom mouse pads and desk mats.

With five years of standardized and stable operation, Hubei Zhengye Factory has built mature production and quality systems that fully comply with RoHS, REACH and international ESG procurement standards. Serving as the unified raw material supply base for S&L and KAL, the factory meets strict market access requirements for Europe, North America, Southeast Asia and other global regions. Leveraging superior manufacturing resources in Hubei, China, it continuously optimizes material formulas and production accuracy based on global market demands. Relying on this high-standard shared supply chain, S&L delivers stable, high-quality customized products to global B2B customers with stronger credibility and guaranteed quality.

The 5th anniversary of Hubei Zhengye Factory marks a new milestone for quality upgrading. In the next five-year development cycle, this China-based professional rubber factory will further leverage regional manufacturing advantages, upgrade automated production equipment, and refine raw material source management. It will continue to provide high-performance, eco-friendly and stable rubber raw materials for S&L and KAL, empowering both brands with more reliable upstream manufacturing support and consolidating S&L’s global product quality competitiveness.

S&L always adheres to the philosophy of “Source Control Determines Product Quality”. By sharing the self-controlled upstream manufacturing resources of KAL’s Hubei production base, S&L realizes full-link quality traceability from raw material production to finished product delivery. Eliminating intermediate outsourcing links and relying on standardized localized manufacturing, S&L effectively controls product quality risks, providing global buyers with highly reliable custom desk accessories and professional B2B customization services with the strong backing of KAL’s mature supply chain strength.
