                                                                  Influence of wall thickness on casting quality








Anyone who specializes in casting design knows that the wall thickness of die-casting parts has a great influence on the quality of stainless steel castings. The walls of castings are too thick and the walls are too thin. Therefore, the wall thickness should be reasonably designed when designing die-casting parts. The quality of the pressure-preserving casting is not affected by the wall thickness.
Taking aluminum casting parts as an example, in general, thin-walled thick-walled die-casting parts have higher strength and better compactness. In view of this, the design of stainless steel castings should follow the principle of ensuring sufficient strength of the castings. As far as rigidity is concerned, the wall thickness should be reduced as much as possible and the wall thickness should be kept uniform. Practice has proved that the thickness of the die-casting part is generally designed to be 2.5-4mm, and the part with a wall thickness of more than 6mm should not be produced by die-casting.
The effect of the wall of the casting being too thick and the wall being too thin on the quality of the casting: if the wall of the casting is too thin, the metal will not be welded well, which will directly affect the strength of the casting, and will cause difficulty in forming; when the wall is too thick or severely uneven It is easy to produce shrinkage and cracks. On the other hand, as the wall thickness increases, the defects such as porosity and shrinkage inside the casting increase, which also reduces the strength of the casting and affects the quality of the casting.

                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
