What are the advantages of die casting molds?
The flow channel of LED radiator die casting mold uses double-sided flow channel structure, LED radiator molding quality is high, LED radiator die casting mold service life is long, but LED radiator die casting mold production efficiency is low, casting production quality is unstable, easy to produce burr and cross marks.
The flow channel of the LED radiator die-casting mold adopts a double-sided flow channel structure. The LED radiator has high molding quality, and the LED radiator die-casting mold has a long service life. However, the production efficiency of the LED radiator die-casting mold is low, the casting production quality is unstable, and it is easy to produce burrs and cross marks
What are the advantages of die-casting dies p>
Die casting die is a casting process that uses pressure. Now it is widely used in all walks of life. Die casting die naturally has incomparable advantages. Here are some conclusions:
1. Die castings have high precision, stable size, good consistency, small machining allowance, and can be used to cast threads, lines, characters, pictures and symbols: the filling process of die casting is always under the effect of pressure, and can clearly cast peaks, valleys, narrow grooves and other shapes. Therefore, die casting can produce very clear threads, lines, characters, pictures and symbols p>
3. Die castings can be coated: as the use scale of die castings is growing, in order to meet the use requirements, the surface of die castings can be coated, such as electroplating, anodizing, polishing, organic maintenance coating, painting, sandblasting, pickling, etc., and then meet the decoration or maintenance requirements p>
4. Selecting the inlay casting method in the die casting die can save the installation process and simplify the manufacturing process: parts made of other materials (such as steel, iron, copper, alloy, aluminum, etc.) can be embedded in the die casting parts to save valuable materials and processing time, and parts with disordered shape and prominent functions can be obtained p>
5. The arrangement of die castings is fine, and the strength and hardness are high: because liquid metals are rapidly cooled in the mold, they crystallize together under pressure, so a layer of metal grains near the outer surface of the die castings are finer and better arranged, which improves the appearance hardness. The tensile strength of the die castings is 25% - 30% higher than that of sand castings, but the elongation is reduced p>
6. The production capacity of die casting is very high: the production process of zinc aluminum die casting is easy to be mechanized and automated. Generally, the cold jade room die casting machine can press 600 39; every eight hours; I00 times. The hot pressing chamber die-casting machine can press 3000 to twice every eight hours. Because the die-casting process is mainly completed on the die-casting machine, it is easy to automate the production process p>
7. Thin wall and shape of casting are disordered p>
Summary: The Z small wall thickness of aluminum alloy die castings can be 0.3mm, the aluminum alloy die castings can be 4.5mm, and the Z small hole diameter can be 0.7mm. The z small pitch of the casting thread is 0.75mm p>
