    FAQ<\/h2>\n

     <\/p>\n

    \n
    Q1: What is the MOQ for custom borosilicate glass double wall lampshade?<\/strong> A: Standard MOQ is 100pcs per shape for clear glass, 300pcs for colored or coated finishes. For trial orders, we offer 50pcs prototyping batch at 1.5\u00d7 unit price.<\/div>\n<\/blockquote>\n
    \n
    Q2: How to ensure the hand blown glass lampshade quality consistency?<\/strong> A: We maintain a master sample for each SKU. Every production batch is compared against the master using digital photogrammetry. Deviation >3% triggers automatic rework.<\/div>\n<\/blockquote>\n
    \n
    Q3: Can you manufacture lamp shades with integrated G9 ceramic socket?<\/strong> A: Yes, we provide G9 ceramic base integration service. The assembly is done in our ESD-protected workshop with dielectric strength testing (2kV\/1min).<\/div>\n<\/blockquote>\n
    \n
    Q4: What is the lead time for double wall glass shade sampling?<\/strong> A: Simple shapes: 7 working days. Complex custom shapes: 12-15 working days. Express shipping (DHL\/FedEx) takes 3-5 days globally.<\/div>\n<\/blockquote>\n
    \n
    Q5: Do you offer exclusive mold protection for custom designs?<\/strong> A: Absolutely. We sign NDA before receiving drawings, and exclusive molds are locked for 24 months minimum. Mold ownership can transfer to client after 10,000pcs cumulative order.<\/div>\n<\/blockquote>\n
