Frequently Asked Questions (FAQ)
-
Q: What is the typical lead time for custom heat sink extrusions?
A: Lead time depends on order quantity and profile complexity. Standard designs typically take 15-20 days after sample approval. For custom profiles, allow 25-30 days for tooling and production. -
Q: Can you provide samples before mass production?
A: Yes, we offer samples for evaluation. Sample costs are negotiable and can be deducted from the final order. Please contact our sales team for details. -
Q: What surface treatments are available for the heat sink?
A: We offer anodizing (clear, black, or custom colors) and powder coating. Anodizing enhances corrosion resistance and thermal emissivity, while powder coating provides additional durability and aesthetic options. -
Q: How do I determine the correct heat sink size for my LED power supply?
A: We recommend providing the power dissipation (watts), ambient temperature, and maximum allowable junction temperature. Our engineering team can perform thermal calculations and suggest an optimized profile. -
Q: Do you offer machining services (drilling, tapping, cutting)?
A: Yes, we provide secondary machining services to meet your mounting requirements. This includes hole drilling, tapping, slotting, and cutting to precise lengths. -
Q: What are the minimum order quantities (MOQ)?
A: For standard profiles, MOQ is typically 500 kg. For custom dies, MOQ is 1000 kg. Smaller quantities may be possible for sample orders. Please inquire. -
Q: Is the 6063 aluminum alloy suitable for outdoor LED lighting?
A: Yes, 6063 alloy has excellent corrosion resistance, especially when anodized. It is widely used in outdoor LED lighting applications such as street lights, floodlights, and garden lights. -
Q: How do you ensure the heat sink's thermal performance?
A: We use thermal simulation software during design and verify performance through prototype testing. Our production follows strict quality control, including thermal conductivity checks on raw materials.
