Ningbo Xianglong Metal Products Co., Ltd.: Driving Innovation in Metal Preservation for 26 Years.
Established in 2000, Ningbo Xianglong has evolved from a local workshop to a global leader in high-end metal fabrication. Our 13,000 sqm facility houses advanced CNC machinery and a workforce of 100+ skilled artisans dedicated to ODM/OEM excellence.
Our commitment to E-E-A-T is backed by German TUV, ISO 9001, and ISO 14001 certifications. We hold 16+ patents in sealing technology and structural design, ensuring every air-tight coffee container meets stringent international standards for food safety and shelf-life extension.
We are the trusted manufacturing backbone for world-renowned brands such as AOB (USA), ASTERM & WIRQUIN (Europe), and DELTA (Australia). Our products are exported to North America, Europe, and Asia, proving our reliability in high-volume, precision-driven markets.
How our OEM coffee containers optimize the "Degassing Period" of specialty coffee beans.
We use high-grade SUS304 stainless steel, ensuring zero corrosion and chemical leaching. Our materials are tested for food-grade compliance with FDA/LFGB standards.
Our containers feature specialized one-way valves that allow harmful CO2 to escape while blocking oxygen ingress, preventing oxidation and flavor degradation.
Utilizing CNC laser cutting and precision stamping, we achieve tolerances within 0.05mm, ensuring a perfect 360° seal with our BPA-free silicone gaskets.
For luxury finishes (Gold, Rose Gold, Matte Black), we use Physical Vapor Deposition, providing a durable, scratch-resistant surface that won't peel or fade.
Located in the heart of Ningbo's industrial cluster, we leverage a hyper-efficient supply chain. From raw material procurement to advanced logistics via the Ningbo-Zhoushan port, our turnaround times for OEM orders are 30% faster than the industry average. Our vertical integration—design, R&D, stamping, welding, and assembly—minimizes middleman costs, passing the "Information Gain" and "Value Gain" directly to our global partners.
Bridging the gap between industrial storage and consumer aesthetic expectations.
Mass-scale canisters for bulk bean resting periods. Our 10L+ silos feature vertical mounting for space optimization in roasting facilities.
Visual merchandising canisters with clear lids or date trackers, helping baristas maintain FIFO (First In, First Out) inventory management.
High-end consumer canisters (1kg - 3kg) designed for home baristas in the US and EU who demand professional-grade freshness at home.
As we move toward 2025, Ningbo Xianglong is integrating IoT technology into our storage solutions. Future prototypes include Bluetooth-enabled humidity and pressure sensors that alert roasters to seal integrity via smartphone apps. We are also transitioning to 100% recyclable packaging and explore bioplastic gaskets to align with global sustainability trends (ESG compliance).
A: Our containers use a proprietary silicone gasket and a reinforced latch mechanism that exerts uniform pressure. Unlike cheap plastic variants, our 304 SS construction doesn't warp over time, maintaining a hermetic seal for years.
A: Yes, we provide full OEM support including laser engraving, PVD custom colors, and bespoke packaging. We serve both high-volume retailers and boutique brands with flexible MOQ requirements.
A: Freshly roasted coffee releases CO2. If sealed without a valve, the pressure can compromise the container or accelerate bean aging. Our one-way valve releases this gas while preventing oxygen from entering, keeping the "bloom" potential high.
A: Absolutely. Our facility is ISO certified, and our products undergo regular testing for FDA (USA) and LFGB (Germany) compliance, ensuring zero migration of heavy metals or harmful chemicals.
