IATF 16949 CERTIFIED CAST MANUFACTURING AND CNC MACHINING FOR HEATSINK PARTS

Strictly speaking, heat is not a kind of energy, but just a way of transferring energy. From a microscopic point of view, after the molecules in the region are impacted by external energy, they are transferred from the molecules in the region with high energy to the molecules in the region with low energy. Therefore, it is generally believed that the transfer of energy is heat. Of course, the most important process or form of heat is heat transfer.

With the enhancement of PC computing power, power consumption and heat dissipation issues have increasingly become unavoidable issues. The operating temperature of an electronic device directly determines its service life and stability. To keep the working temperature of each component within a reasonable range, in addition to ensuring that the temperature of the working environment is within a reasonable range, it must also be treated with heat dissipation. Especially for the PC's CPU, if the user has overclocked, to ensure its stable work, it must effectively dissipate heat. In another area of ​​heat dissipation, the heat dissipation performance of LEDs also deeply affects the life of the lamps.

There are three main ways of heat transfer: conduction/convection/radiation. Any radiator will also use the above three heat transfer methods at the same time, but the emphasis is different. Take the CPU heat dissipation as an example. The heat is continuously emitted by the CPU work, and is transferred to the heat sink by conduction through the heat sink base that is in close contact with the core. Then, the heat reaching the heat sink is transferred by other means such as fan blowing. The heat is sent away.

For the radiator, the most important thing is that its base can absorb as much heat as possible from the CPU in a short time, that is, the ability to absorb heat instantly. Only metals with high thermal conductivity can be competent. Among them, the die-cast radiator has gradually become a leader in the radiator industry because of its cost advantage and sufficient weight.

Combine all this with a complete selection of high volume die casting equipment and the personal attention of a team of manufacturing and engineering experts, and you have the casting industry equivalent of muscle heat sink performance. Heat Sink Die Casting by Minghe Casting is designed to meet the most demanding standards of the Cooler. To Minghe this is more than a specification; it is a mission we accomplish with components that are precisely on spec, delivered exactly when you need them.

We Provide Casting Services Include:

Minghe Casting services working with sand casting、metal casting 、investment casting lost foam casting, and more.

china minghe sand casting

Sand Casting

Sand Casting is a traditional casting process that uses sand as the main modeling material to make molds. Gravity casting is generally used for sand molds, and low-pressure casting, centrifugal casting and other processes can also be used when there are special requirements. Sand casting has a wide range of adaptability, small pieces, large pieces, simple pieces, complex pieces, single pieces, and large quantities can be used.
China Minghe metal casting

Permanent Mold Casting

Permanent Mold Casting have a long life and high production efficiency, not only have good dimensional accuracy and smooth surface, but also have higher strength than sand castings and are less likely to be damaged when the same molten metal is poured. Therefore, in the mass production of medium and small non-ferrous metal castings, as long as the melting point of the casting material is not too high, metal casting is generally preferred.

 

China  investment- Casting

Investment Casting

The biggest advantage of investment casting is that because investment castings have high dimensional accuracy and surface finish, they can reduce machining work, but leave a little machining allowance on the parts with higher requirements. It can be seen that the use of investment casting method can save a lot of machine tool equipment and processing man-hours, and greatly save metal raw materials.
China MINGHE Lost Foam Casting

Lost Foam Casting

Lost foam casting is to combine paraffin wax or foam models similar to the casting size and shape into model clusters. After brushing and drying refractory coatings, they are buried in dry quartz sand for vibration modeling, and poured under negative pressure to gasify the model. , The liquid metal occupies the position of the model and forms a new casting method after solidification and cooling.

 

china minghe die casting process

Die Casting

Die casting is a metal casting process, which is characterized by applying high pressure to the molten metal using the cavity of the mold. Molds are usually made of higher-strength alloys, and this process is somewhat similar to injection molding. Most die castings are iron-free, such as zinc, copper, aluminum, magnesium, lead, tin, and lead-tin alloys and their alloys. Minghe has been China's top die casting service since 1995.
China Minghe Centrifugal Casting

Centrifugal Casting

Centrifugal Casting is a technique and method of injecting liquid metal into a high-speed rotating mold, so that the liquid metal is centrifugal motion to fill the mold and form a casting. Due to the centrifugal movement, the liquid metal can fill the mold well in the radial direction and form the free surface of the casting; it affects the crystallization process of the metal, thereby improving the mechanical and physical properties of the casting.

 

China Low Pressure Casting

Low Pressure Casting

Low Pressure Casting means that the mold is generally placed above a sealed crucible, and compressed air is introduced into the crucible to cause a low pressure (0.06~0.15MPa) on the surface of the molten metal, so that the molten metal rises from the riser pipe to fill the mold and control Solidified casting method. This casting method has good feeding and dense structure, easy to cast large thin-walled complex castings, no risers, and a metal recovery rate of 95%. No pollution, easy to realize automation.
China MINGHE Vacuum Casting

Vacuum Casting

Vacuum Casting is a casting process in which metal is smelted, poured and crystallized in a vacuum chamber. Vacuum casting can minimize the gas content in the metal and prevent metal oxidation. This method can produce very demanding special alloy steel castings and extremely easily oxidized titanium alloy castings. Minghe Casting has a vacuum casting sub-factory, which is enough to solve all the problems related to vacuum casting
