FAQ
Q1: What is the MOQ for custom borosilicate glass double wall lampshade? 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× unit price.
Q2: How to ensure the hand blown glass lampshade quality consistency? 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.
Q3: Can you manufacture lamp shades with integrated G9 ceramic socket? A: Yes, we provide G9 ceramic base integration service. The assembly is done in our ESD-protected workshop with dielectric strength testing (2kV/1min).
Q4: What is the lead time for double wall glass shade sampling? A: Simple shapes: 7 working days. Complex custom shapes: 12-15 working days. Express shipping (DHL/FedEx) takes 3-5 days globally.
Q5: Do you offer exclusive mold protection for custom designs? 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.
