Product Description
Die cast heat sink
The characteristics of die casting type heat sink is a use of high pressure, mandatory to molten metal hydraulic into the shape of a complex metal mould precision casting process, is a kind of pour molten alloy into indoor, filling at high speed steel mould cavity, and the liquid alloy solidification under pressure to form a casting casting method, the main characteristics of die casting is distinguished from other casting method is of high pressure and high speed.
advantages of die casting type radiator thermal conductivity, high thermal efficiency. Die casting is a precision casting method, through the die casting and become part of a smaller size tolerance of high precision surface, hydraulic fin die casting technology can produce complex structures of products, under the most affection in die casting does not need too much turning processing can assembly applications, low production cost.
shortcomings:
Restrictions on die-casting alloys: At present, there are only six die-casting alloys such as zinc, tin, lead, copper, magnesium, aluminum, among which copper alloy has the highest melting point.
The cost of equipment is high, and the cost and operating expenses of the equipment required by the die casting production, such as die casting machine, melting furnace, insulation furnace and die casting mold, are quite high.
Due to poor air tightness of castings, leaching treatment is usually required for large castings
The process capacity is 1250T, and the maximum length of the product can be about 1000mm. For small products, zinc alloy is the most suitable, and the minimum length of zinc alloy is about 2cm.
