Jiasite, a Tianjin-based listed manufacturer of bicycle and electric vehicle components, has installed five Zhongrui iSLM420TN metal LPBF systems for production applications. The 2026 deployment targets three distinct workflows: integrated molds for EV seat cushion lidding, conformal cooling channels in bicycle mold inserts, and one-piece Ti-6Al-4V saddle bases for premium bicycles. Jiasite reports that the mold lidding line reduced manual labor by approximately 75% post-automation, while the conformal cooling molds shave 25 to 30 seconds per cycle. The titanium saddle bases achieve 30-40% weight reduction over conventional aluminum or steel via lattice and topology-optimized designs. Jiasite states a 98%+ yield on these core components and a sub-one-year payback on the molding application alone.
This deployment illustrates how metal AM is entering mid-volume tooling and serial-part production in the automotive-adjacent two-wheeler vertical, a segment that has largely remained a press-release gap compared to aerospace or consumer electronics. Jiasite’s economics - measurable labor reduction, cycle-time compression, and rapid payback - mirror the industrial-tooling logic that has quietly become one of AM’s most repeatable business cases. The company did not select a Western or export-oriented Chinese OEM; it chose Zhongrui, a mid-tier domestic LPBF builder. This signals that Chinese metal PBF-LB vendors are now competing on reliability and service responsiveness at scale, not only on machine price. The titanium saddle application, while currently a low-volume premium product, creates a referenceable design-to-production path for consumer hard goods that could pull through further adoption in adjacent categories like e-bike frames or medical mobility aids.
For AM industry observers, this is a grounded data point rather than a headline shift. The practical takeaway is that Zhongrui’s installed-base service model and the iSLM420TN’s batch stability are now validated at a production-reliant customer with clear unit economics. The next test is whether Jiasite expands beyond the current five machines toward a dozen or more - a move that would confirm the tooling use case is repeatable and the titanium saddle line is scaling toward genuine serial production.
