What are the standard payment terms and international shipping options for B2B procurement?

The sample lead time for a fully customized OEM duct design typically ranges from 7 to 15 days from design approval to sample completion. This timeline includes material sourcing, prototype fabrication, and initial quality inspection. For simpler customizations (such as color or length adjustments), samples can often be ready within 3 to 7 days. Complex designs involving new materials or structural features may require additional time for R&D and testing. Once the sample is approved, bulk production lead time is approximately 15 to 30 days depending on order volume. We recommend initiating the customization process well in advance of your project deadline.

Custom color and logo printing costs vary depending on order quantity, complexity of the design, and number of colors required. For standard custom colors (such as high-visibility yellow or military-grade camouflage), there is typically no additional cost for orders meeting our MOQ. For custom logo printing, we charge a modest setup fee for screen printing or heat transfer tooling, which is often waived for larger orders. We recommend contacting our sales team with your specific color and logo requirements for a detailed quote. All customizations are subject to our standard OEM/ODM process and quality control protocols.

NUOENWEI offers flexible air ducting systems in standard inner diameters of 8" (200mm), 10" (250mm), 12" (300mm), and 14" (350mm). Custom diameters are available upon request for specialized applications. For length, standard options include 1 meter, 1.5 meters, and 2 meters, with custom lengths available to meet specific project requirements. Our flexible ducts are available in diameters ranging from 100mm to 1500mm. Whether you need short sections for tight installations or extended lengths for large-scale infrastructure, we can accommodate your specifications. Please contact our sales team with your dimensional requirements for a custom quote.

Our R&D team follows a rigorous, customer-centric design process for aerospace PCA hoses applications. We begin by analyzing the specific operational requirements—including temperature range, pressure conditions, airflow volume, and installation constraints. For aerospace applications, we prioritize lightweight materials, flame retardancy (UL94 VTM-0 certified), durability under extreme conditions, and precision fit to aircraft connectors. Our design process incorporates computer-aided design (CAD) , material selection from our portfolio of high-grade PVC, Hypalon (CSM), and other specialized materials, prototyping, and rigorous testing for thermal performance, pressure resistance, and structural integrity. We collaborate closely with clients throughout the development cycle to ensure the final product meets all performance and certification requirements.

NUOENWEI has extensive experience in OEM (Original Equipment Manufacturer) and ODM (Original Design Manufacturer) services for specialized air conditioning insulation ducts. Our process begins with a consultation to understand your specifications, followed by design and prototyping by our R&D team. We offer 100% QC inspection before shipping and can accommodate custom requirements including diameter (100mm to 1500mm), thickness (starting from 3mm), thermal insulation performance, antibacterial coatings for hygiene-sensitive applications, and corrosion resistance. Our specialty air conditioning insulated ducts are used in medical, food processing, electronics, and industrial manufacturing sectors. With an annual production capacity of 200,000 meters for PCA hoses, we can handle both small-batch custom orders and large-volume production runs.
