When turning aluminum, it is important to open the aluminum profile drawing die. The die casting radiator requires to open the die casting die. The cold forging radiator requires opening the forging die. If the mold price of items with the same form is split into high, medium, and cheap, the price of die-casting mold is high, the price of forging mold is moderate, and the price of profile drawing mold is low. If the processing cost of goods with the same form is split into high, medium, and low, the price of profile machining is high, the price of die casting is moderate, and the price of forging is comparatively cheap.
Material cost: ADC12 for die casting is reasonably inexpensive, and a6063 for machining and forging. The cost will rise accordingly. Led radiators (often in the form of sunflowers) are made from a6063 aluminum profile machining (car metal). The benefits are: the heat dissipation effect of the product is reasonably excellent, and the surface treatment of the completed product, such as anodic oxidation, is relatively straightforward. The mold production cycle is quick, generally takes 10 ~ 15 days, and the mold pricing is inexpensive. The downside is that the subsequent machining cost is expensive and the output is poor.
The LED radiator is created by die casting, and the material is ADC12.
The benefits are: cheap processing cost and great manufacturing capacity. If the mold is permitted, it may create radiators of different forms. Molds are expensive, and the production process takes 30 to 45 days on average.
Cold-forged LED radiators may theoretically be built of any material.
The benefits are: cheap processing cost and great manufacturing capacity. The mold production cycle is quick, generally takes 10 ~ 15 days, and the mold pricing is inexpensive.
Forging has the drawback of not allowing for the creation of objects with intricate aesthetics due to its inherent limitations. If the product consumption is minimal, it is advisable to employ machine processing. It is advised to employ die casting because of big product consumption and complicated form. Because of its high consumption and straightforward design, the device has a devoted following. It is advised to employ cold forging.
Foremost, let’s discuss the cast zinc alloy shell. Currently, the lamp’s cast zinc alloy casing has a thermal conductivity of 80-90 watts per M.K. The real heat conductivity is significantly worse when using supplementary oxidation residue, surface oil injection, or electroplating. Die casting of the LED lamp cup in aluminum alloy aa1070 results in a tiny heat dissipation area and is thus not favorable to efficient heat dissipation. Thermal conductivity is good, ranging from 180-190w/M.K. for the aluminum alloy 6030-t5. It is possible to reduce the heat dissipation scale to a minuscule 1mm thickness. For LED lighting, it is essential to keep the cup body temperature below 50 ° C to limit the amount of light attenuation and maintain lamp quality. This may be achieved with the product’s unique heat dissipation structure design. When compared to a die-casting shell, the heat dissipation efficiency of a sunflower radiator with the same size LED lamp cup is more than one-third greater.
Modern streamlining was used to develop the product’s look, which not only adheres to public aesthetic standards but also yields a classic silhouette. Furthermore, LED sunflower radiators are up to one-third lighter than die-casting shells, making them ideal for large-volume LED lights and allowing for significant savings in shipping costs. No, die castings aren’t a waste of money. Die castings can be made quickly and cheaply in large numbers because of their high speed and low cost of manufacturing.
Die cast zinc alloy and zinc alloy have the following main differences:
The tensile strength of zinc alloys ranges from 260 to 440 MPa. The tensile strength of aluminum alloys ranges from 120 to 290 MPa. Overall, zinc alloy has better hardness and higher tensile strength than aluminum alloy. The use is also varied. Aluminum alloy has nice form, but poor strength, yet its strength is greater than that of aluminum. Ideal for medium-strength structural materials capable of supporting heavy loads. Corrosion resistance is high in aluminum and zinc alloys. Zinc alloy has better hardness and tensile strength than aluminum alloy, although there is no exact limit.
Alloys made of aluminum have a low density but a high hardness rating. An excellent combination of hardness and tensile strength may be found in alloys. Their biggest distinction resides in the makeup. Zinc is the primary constituent of zinc alloys, which often include more than 85% of zinc, whereas the primary constituent of aluminum alloys typically contains more than 87% aluminum. The alloy’s kind and brand are factors to consider. Zinc alloy, like aluminum alloy, may be understood simply as a mixture of zinc and other alloying components.
A zinc-based alloy with additional elements is used for a variety of applications. Zinc alloy has low melting point, good fluidity (castable thin-walled parts), easy fusion welding, brazing and plastic processing, corrosion resistance in dry air and atmosphere, and easy recovery and remelting of residues and wastes; However, the creep strength is low, and natural aging will change the size.
Because the zinc alloy content is roughly 2.5 times more than the aluminum alloy content and costs the same, the zinc alloy’s material cost is around 2-3 times greater than the aluminum alloy’s material cost. Now many firms seek to utilize aluminum alloy to replace zinc alloy in order to cut costs, but some can not be replaced, since the strength, hardness and forming performance of zinc alloy are much superior than aluminum alloy.
If you wish to polish and electroplate the surface of your product and demand great aesthetic quality, you have to utilize zinc alloy. Aluminum alloy material is difficult to achieve high surface quality criteria, since aluminum alloy has poor die-casting molding performance, and it is easy to develop a lot of pores on the surface of products in process. After electroplating, the surface quality is quite bad.
