Frequently Asked Questions
Q1: What is the minimum order quantity (MOQ) for this grille?
A: Our MOQ is typically 500 pieces for standard designs. For custom patterns, MOQ may be 1000 pieces. However, we can discuss smaller trial orders for first-time customers.
Q2: Can you achieve a tolerance better than ±0.05mm?
A: Yes, for specific requirements we can achieve tolerances down to ±0.02mm, subject to design complexity and material thickness. Please consult our technical team.
Q3: How does the dustproof performance compare to mesh or foam grilles?
A: Our etched aluminum grille provides a rigid barrier that is more durable than foam and offers better airflow than dense mesh. It is tested to IP5X dust protection, suitable for most consumer electronics.
Q4: What surface treatments are available?
A: We offer matte, brushed, and anodized finishes. Anodizing adds extra hardness and color options (black, silver, gold, etc.). All treatments are available upon request.
Q5: Can you produce grilles with curved or complex shapes?
A: Yes, our etching process can handle 2D flat patterns easily. For 3D curved shapes, additional forming steps may be required. We can discuss feasibility based on your design.
Q6: How long is the lead time for a custom order?
A: Typical lead time is 15-25 days after sample approval, depending on order quantity and complexity. Rush orders can be accommodated with prior arrangement.
Q7: Do you provide free samples?
A: Yes, we offer free samples for existing designs (customer pays shipping). For custom samples, a nominal tooling fee may apply, refundable with mass production orders.
Q8: Are your grilles compatible with Bluetooth speakers that have internal antennas?
A: Aluminum can affect wireless signals if placed directly over antennas. We recommend designing the grille pattern with sufficient open area or using a non-metallic insert in the antenna region. Our engineering team can advise on optimal designs.
