                                                                 What are the requirements or precautions for the casting of precision castings during casting?













To make it easy to make models, core boxes and shapes:
1) The shape of Suzhou precision castings should be simple, so as to facilitate the moulding, the casting parting surface should be as flat as possible and the number is the smallest;
2) The internal cavity stress of precision castings is not required or less used in casting. When using the core, it should be convenient to support, fix and exhaust sand. If necessary, there should be enough process holes;
3) For the inner and outer sides of the precision castings and the ribs and other structures, a certain structural inclination should be provided in the direction of the die-cutting;
4) The boss part on the precision casting should not be too different from the precision casting body. It is best to take the same height. The several bosses on the same side are preferably connected to the whole convex part.

                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
