Aluminum casting manufacturers win advantages in the automotive industry due to their low melting point, easy casting and high precision.





Now all kinds of metal casting processes are very advanced. Why do aluminum casting manufacturers win the dominant position in the automotive industry? This should be said from the characteristics of aluminum castings. Aluminum castings have low melting point, easy casting, excellent precision and appearance, and stable performance, so they are unanimously recognized by many automobile manufacturers. Aluminum casting manufacturers have a very important role in the current industry. Let's talk about why aluminum casting manufacturers will be widely used.

Aluminum casting manufacturer's function
The process of using aluminum castings in production is facing the unparalleled advantages of many other castings. Its advantages are in the lightweight automotive industry. Aluminum casting has a wide range of applications in the automotive industry. This aspect of the car is mainly because the density of aluminum castings is smaller than that of iron and steel castings, and the strength is very high. After a series of competitions, aluminum castings manufacturers stand out and reduce part of the weight, so it is well known. In the production of aviation and machinery, aluminum alloys have a large weight.

Because of its low melting point, aluminum castings also play a vital role in the operation. Aluminum casting is widely used in metal and pressure casting, and it has become the most basic method. The intrinsic quality of the castings, the appearance of the smooth and smooth internal precision is also higher, and the power produced is also improved a lot.


Aluminum castings manufacturers have outstanding casting functions in the process of operation, mainly because of the low melting point of their products, so they can be widely used in metal casting and casting methods such as pressure casting, which will improve the connotation quality of castings. Scale accuracy and appearance, as well as production power.

The latent heat of condensation of aluminum castings is relatively large. Under the same conditions, the aluminum liquid is much longer in coagulation time than cast iron and cast steel, and has good fluidity, which is advantageous in casting thin walls and messy castings.

After the high-temperature metal liquid is burned into the aluminum casting manufacturer, there will be a large amount of gas inside, which must be smoothly discharged from the mold. This performance that allows gas to pass through is called gas permeability, otherwise it is inside. There will be insufficient pores, affecting the quality, and the permeability and moisture content of the clay have a certain relationship.

                Ten things that must be paid attention to in precision casting! 1. Unblock all obstacles to the channel and site. 2. Check if the ladle is dry, whether the bottom of the bag, the ear, the bag and the end are safe and reliable, and whether the rotation is flexible. Do not use dry Iron ladle. 3, all tools in contact with molten iron, must be preheated to 500 degrees Celsius before use, otherwise it should not be used. 4, the ladle should not exceed 80% of the volume, the ladle should be smooth and slow, keep the steps to prevent the overflow of molten iron. Cast iron 5, before the crane crane should check the iron of the hook, the chain is reliable, the chain is not allowed to knot, there is a person responsible for tracking the iron in the water There must be no staff on the line. 6. Strictly implement the "six will not fall": (1) The temperature of molten iron is not enough; (2) The molten iron grade is not poured; (3) does not b

                                                                   Factors affecting the surface roughness of stainless steel castings Surface roughness is another major quality indicator for stainless steel castings , generally less than 3.2 μm, between 0.8 and 3.2 μm. There are many factors affecting the surface roughness of castings, such as the pressure type, the surface quality of the investment and stainless steel, the casting process, the type of alloy and other factors. (1) Profile and investment surface quality. The surface roughness of the investment mold is the most important part affecting the surface roughness of the casting, and it is related to the surface quality of the molding, the compression molding method and the pressing process parameters. (2) Stainless steel surface quality. Stainless steel is a columnar columnar structure network, and refractory materials, additives, and water are filled in the middle, so that there are pores of different sizes on the su
