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.

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.

Yes. NUOENWEI specializes in providing fully customized air ducting solutions tailored to your specific industrial ventilation requirements. Customization options include: inner diameter (standard sizes 8", 10", 12", 14" with custom diameters available upon request), length (standard 1m, 1.5m, 2m, with custom lengths available), material composition (PVC, Hypalon/CSM, high-temperature resistant materials, lightweight materials), color (high-visibility yellow, military-grade camouflage, custom colors), insulation type (single-layer non-insulated or multi-layer insulated), and structural features (wire-reinforced retractable, foldable with wear strips, webbing-bound foldable). Our R&D team works closely with clients to develop solutions for aerospace, mining, construction, and HVAC applications.

Shipping costs are calculated based on order volume, weight, destination country, and chosen shipping method (sea freight, air freight, or express delivery). We provide FOB pricing from various locations, with shipping costs quoted separately based on current freight rates. For logistics efficiency, sea freight typically takes 20-40 days depending on destination, while air freight and express delivery can arrive within 3-10 days. We work with multiple freight forwarders to secure competitive rates and reliable service. For urgent infrastructure project deadlines, we recommend air freight or expedited sea freight options.

To request a technical consultation or product sample, simply fill out the inquiry form on our website with your project requirements, or contact our sales team directly via email or phone. For sample requests, we typically prepare and ship samples within 3 days for standard products. Custom sample production may take 7 to 15 days. Our technical team is available to provide detailed product specifications, application guidance, and custom solution recommendations at no cost.

Every shipment includes comprehensive documentation to facilitate smooth customs clearance and project inspection, including: Commercial Invoice, Packing List, Bill of Lading (for sea freight) or Air Waybill (for air freight), Certificate of Origin, ISO9001 quality certification, and UL94 flame retardancy certification. Upon request, we can also provide third-party testing reports from accredited laboratories, material safety data sheets (MSDS) , and product-specific test certificates verifying antistatic performance, tensile strength, and other technical parameters

Our standard MOQ for custom-branded flexible ducts is 6 meters for PCA hose products and 5 meters for air conditioning insulated ducts. For first-time buyers looking to test samples, we can often accommodate smaller quantities—please inquire with our sales team. Volume discounts are available for annual supply contracts and large-scale infrastructure projects. Our supply capacity reaches 500,000 meters per year for ordinary air ducts and 200,000 meters per year for PCA hoses

We accept Telegraphic Transfer (T/T), Western Union, and PayPal as standard payment methods. Regarding international shipping, we offer options such as FOB (Free On Board) and CIF (Cost, Insurance, and Freight) with departures from various ports. We partner with major freight forwarders to provide a range of shipping services—including sea freight, air freight, and express delivery—tailored to your timeline and budget.
