Our R&D focus is centered on three pillars: Material Passivation, Atmospheric Control, and Ergonomic Integration.
Utilizing high-grade SUS304/316 stainless steel with advanced PVD vacuum coating. This ensures zero chemical reactivity with coffee oils and maximum corrosion resistance.
Integration of one-way CO2 degassing valves and precision-engineered silicone seals that maintain a negative pressure environment, halting oxidation in its tracks.
Our future roadmap includes IoT-enabled lids with humidity and temperature sensors, providing real-time freshness data to commercial users via mobile apps.
Our 13,000㎡ facility utilizes high-precision laser cutting to ensure every component of our airtight coffee jars and silos meets a tolerance of ±0.05mm.
Leveraging the same technology used in our ISO-certified floor drains, we employ automated welding to create seamless, leak-proof joints in our coffee silos.
Real-time tracking of raw materials and finished goods ensures that our OEM/ODM clients experience 0-risk collaboration and timely delivery schedules.
The global coffee market is evolving. Roasters are no longer just selling beans; they are selling an experience. This transition requires Macro-Industry Solutions that span the entire value chain. As a leading supplier, we provide more than just "jars." We provide branding tools. Our ODM services allow for deep customization—from laser-etched logos to bespoke color palettes that align with a brand's visual identity.
Furthermore, our products are engineered for Localization Support & Compliance. Whether it’s meeting FDA food-grade standards in North America, LFGB requirements in Germany, or CE certification in Australia, our products are pre-vetted for global entry. This reduces the legal and regulatory burden on our partners, allowing them to focus on market expansion.
For large-scale commercial hospitality and boutique roasteries, we offer Supply Chain Resilience. By diversifying our manufacturing processes and maintaining robust stock levels of raw 304 stainless steel, we buffer our clients against the volatility of global metal prices and shipping delays.
Ningbo Xianglong Metal Products Co., Ltd., with 26 years of deep expertise in the metal products sector, specializes in providing one-stop ODM/OEM customization services for global clients across categories including floor drains, wall niches, coffee bean storage bins, and metal office furniture.
Equipped with core processes including laser cutting, stamping and bending, precision welding, and automated assembly, the company ensures consistent quality through standardized production. It holds authoritative certifications such as German TUV, ISO 9001, and ISO 14001.
From 500 units to 50,000 units, our lines are optimized for rapid scale-up without quality degradation.
Direct-from-factory pricing combined with high-level automation reduces overhead, providing a competitive edge in retail pricing.
We don't just take orders; we act as a design partner, helping you iterate on product features like 360° rotating outlets or invisible rectangle drains.
Stainless steel (SUS304) offers superior thermal stability and zero UV penetration, which are the two biggest enemies of coffee freshness. Unlike plastic, our jars do not leach BPA or absorb odors over time.
Yes. Our facility is equipped for PVD vacuum coating, powder coating, and precision laser engraving, allowing for a wide range of finishes from matte black to rose gold.
We use a combination of automated precision welding and 100% pressure testing on all sealed components. Our ISO 9001 certification mandates a multi-stage QC process at every production step.
While we are a high-capacity factory, we maintain a dedicated prototype and small-batch line to support growing brands in their initial market entry phase.
