Aluminum Heat Sink

Die-Cast Heat Sinks

In lighting applications, heat sinks are typically made from materials with high thermal conductivity, which allows them to efficiently draw heat away from the light source and release it into the surrounding environment.

Benefits

1. High Thermal Conductivity

One of the most essential qualities of a heat sink is its ability to transfer heat efficiently. Aluminium boasts excellent thermal conductivity—roughly 205 W/m·K.

2. Corrosion Resistance

Aluminium naturally forms a protective oxide layer when exposed to the environment, which protects it from corrosion.

Aluminum Heat Sink

Gravity-cast radiator cooling fins are thin, heat-conductive components designed to improve heat dissipation in cooling systems.

Die-Cast Heat Sinks

Die-cast heat sinks are made by pouring molten aluminum into a mold, allowing for complex shapes with higher precision.
This method is commonly used for outdoor lighting fixtures, street lamps, and other heavy-duty applications requiring durability and precision.
When designing LED heat sinks, we focus on directing the flow of aluminium along the fins and grooves, optimising heat dissipation by minimising thermal resistance.

Shipping & Delivery in International Business

In the world of international trade, Incoterms (International Commercial Terms) play a vital role in defining the responsibilities of buyers and sellers regarding the delivery and shipping of goods. These terms govern various aspects of shipping, such as who pays for transportation, insurance, duties, and other costs associated with the shipment. At DSW, we understand the importance of these terms and ensure clarity in our shipping practices to facilitate smooth transactions for our business clients worldwide.

Shipping
  • EXW (Ex Works): Buyer covers all costs and risks from the seller’s premises, including shipping and customs.
  • FOB (Free On Board): The seller handles costs and risks until the goods are loaded; the buyer takes over from there.
  • CIF (Cost, Insurance, and Freight): The seller pays for shipping and insurance; the buyer takes responsibility at the destination port.
  • DDP (Delivered Duty Paid): Seller covers all costs, including shipping, customs, and delivery to the buyer’s premises.
  • CFR (Cost and Freight): The seller pays for transportation to the destination port; the buyer handles insurance and takes responsibility upon arrival.
These terms define shipping costs and responsibilities in international trade.

Customs Duties and International Shipping

Regarding international orders, customs duties, taxes, and import charges may apply. Under Incoterms, the seller and buyer share these responsibilities differently:

  • For EXW and FOB terms, the buyer is responsible for customs duties and taxes upon the goods' arrival in the destination country.
  • For CIF and DDP terms, the seller handles customs clearance and payment of any applicable duties and taxes.
Please note that DSW Industry is not responsible for customs duties or taxes that may apply to your order under international trade agreements. We recommend you check with your local customs office for further details regarding import fees, as these charges may vary.
