How to Buy

Welcome to CHNSIGN! We specialize in manufacturing high-quality, custom advertising lightboxes and Signs for global clients. Ordering is simple and streamlined. This guide walks you through every step, especially focusing on providing your design – the key to your perfect display products.

Step 1: Explore Our Products & Capabilities

  • Confirm Types: Review our standard lightbox types (e.g., Front-Lit, Back-Lit, Slim, Outdoor, Double-Sided), common sizes, materials (aluminum, acrylic, steel), lighting options (LED types, brightness), and finishes.
  • Understand Customization: We excel at custom manufacturing. Don’t see your exact size, shape, or feature? No problem! We can build it based on your specifications and design.
  • Key Considerations: Think about:
    • Usage: Indoor or Outdoor (IP Rating needed)?
    • Size & Thickness: Desired dimensions (Width x Height x Depth).
    • Materials: Frame (e.g., aluminum alloy), graphic panel (e.g., opal acrylic), backing.
    • Lighting: LED type (SMD, COB), color temperature (e.g., 4000K, 6500K), brightness (lumens), dimmable?
    • Installation: Wall-mounted, freestanding, hanging? Any special brackets?
    • Graphics: How will the graphic be applied (printed vinyl, direct print, removable face)? Note: We typically manufacture the lightbox structure; you or your printer usually handle the final graphic overlay, unless we offer full service.
  • Pro Tip: Note down product codes or descriptions of items close to your needs as a starting point.

Step 2: Prepare Your Design (The Most Important Step!)

Providing a clear, accurate design drawing is essential for getting an exact quote and ensuring your lightbox is manufactured perfectly.

  • What We NEED in Your Design Drawing:
    • Detailed Dimensions: All critical measurements in millimeters (mm) or inches (in). Include overall width, height, depth, material thicknesses, cut-out sizes, hole positions (for mounting, wiring, vents), and radii for curves.
    • Clear Views: Ideally, provide multiple views: Front, Side (Profile), Top (Plan), and any relevant cross-sections. Isometric views can also be helpful for complex shapes.
    • Material Specifications: Clearly label each component’s material (e.g., “3mm White Opal Acrylic”, “1.5mm Aluminum Ally Frame”, “1.0mm Galvanized Steel Back Panel”).
    • Construction Details: Indicate assembly methods (e.g., screw types, rivet positions, adhesive bonding), layer stack-up (order of materials), and any internal structures or supports.
    • Lighting Layout: Show the position, type, and quantity of LED modules/strips. Specify wiring paths and driver location if known.
    • Mounting & Access: Detail mounting bracket types, positions, and hole sizes. Show access points for graphic changing or maintenance.
    • Electrical Specifications: Voltage (e.g., 100-240V AC, 12V/24V DC), plug type required, IP rating for outdoor units.
    • Finishes: Specify colors or finishes (e.g., “Powder Coat RAL 9010 Pure White”, “Brushed Aluminum”).
  • Accepted File Formats (Preferred):
    • Vector Formats: .CDR (Coreldraw), .DWG (AutoCAD), .AI (Adobe Illustrator – outline paths only), These are best for precise manufacturing.
    • Detailed PDFs: High-resolution PDFs with all dimensions clearly marked and scalable. Ensure layers are flattened.
  • What We CANNOT Use Effectively:
    • Raster images only (.JPG, .PNG, .BMP) – unless accompanied by VERY detailed dimensioned drawings.
    • Hand-drawn sketches without precise, unambiguous measurements.
    • Rough concept drawings without technical details.
  • Pro Tips for Design Submission:
    • Use Layers: If using CAD/AI, keep dimensions, outlines, and notes on separate layers.
    • Include a Title Block: List your company name, project name/number, date, scale, and units (mm/in).
    • Call Out Critical Tolerances: If specific dimensions are extra critical, note the tolerance (e.g., “500mm +/- 0.5mm”).
    • Simplify: Remove unnecessary background elements or clutter.
    • Annotate Clearly: Use text notes to explain anything not immediately obvious from the drawing.

Step 3: Request Your Quote

  • Contact Us: Use our website’s Contact form, email us directly at [sales@chnsign.com], or message us via WhatsApp [+86 176 8820 3368].
  • Provide Essential Information:
    • Your company name and contact details.
    • Project name/reference.
    • Quantity required.
    • Intended use (Indoor/Outdoor? Specific environment?).
    • Any product codes or descriptions from Step 1 that are relevant.
    • CRUCIALLY: Attach your complete Design Drawing(s) in an acceptable format.
    • Any additional notes or special requirements (e.g., urgent deadline, specific certifications).
  • What Happens Next: Our engineering team will review your design for manufacturability and may ask clarifying questions. We’ll then calculate the cost based on materials, labor, complexity, and quantity.

Step 4: Review & Confirm Your Quotation

  • You’ll receive a detailed Proforma Invoice (PI) including:
    • Itemized description of the lightbox based on your design.
    • Unit price and total price.
    • Payment terms (e.g., T/T 50% deposit, 50% before shipment).
    • Incoterm (e.g., FOB, EXW, CIF).
    • Production lead time.
    • Validity period of the quote.
  • Carefully Review: Ensure all details, specifications, and pricing match your expectations. Ask questions if anything is unclear.
  • Place Your Order: Once satisfied, approve the PI and make the required deposit payment. Send us the payment receipt. This officially starts your order!

Step 5: Production & Quality Control

  • Design Finalization (If needed): We might create final production drawings based on your design and share them for your approval before cutting metal.
  • Manufacturing: Our skilled team builds your lightboxes using quality materials and precise techniques.
  • Quality Checks: Your order undergoes rigorous inspections throughout production and a final check before packing. We can provide photos/videos upon request.

Step 6: Shipping & Delivery

  • Packaging: We pack your lightboxes securely in export-worthy crates or cartons to withstand international shipping.
  • Documentation: We prepare all necessary shipping documents (Commercial Invoice, Packing List, Bill of Lading/Air Waybill, Certificate of Origin if needed).
  • Shipping: We coordinate shipment via your chosen freight forwarder or arrange it based on the agreed Incoterm. We provide tracking information.
  • Delivery: Your lightboxes arrive at your designated port or warehouse!
