Gas block, cast parts under the surface lubrication, but the shape is irregular, it is difficult to set the overflow system, gas accumulation; When the molten metal to move, turbulence is strong, gas are closed. 3 it is plastic cavity with residue, dosage of coating or coating method is undeserved, cause local coating deposition. Solution to the die casting crack: improving the structure of the...

How to improve the surface polishing quality of die casting, die casting products wall can't be too thin. Large area of thin wall prone to owe defects such as water, cold. Die-casting products wall thickness choice: under normal circumstances, the wall thickness should not be greater than 4.5 mm, small and medium sized castings is suitable for wall thickness of the zinc alloy 1-3 mm, 1.5 4...

Die casting and polishing process: mechanical polishing: refers to the use of physical methods, such as cutting, grinding, the surface plastic deformation occurs, the surface of the convex part fill concave part, so as to reduce and smooth the surface roughness, improve the surface roughness. Mechanical polishing and lead to the destruction of the metal surface crystal and metamorphism, produce...

Die casting weight lighter at the same time, can reduce the burden of people, reduce the risk. Because of the toughness is very good, determines its plasticity, can be designed into various shapes, ductility is particularly advantage. Because of this, the casting can be recycled, save material, wider application range. Because of this feature, also determines its ideas, can freely.Through this...

Alloy die casting: the advantages of the alloy at high temperature has a strong corrosion resistance, electrical conductivity and thermal conductivity is high, is a relatively light alloy; Brittle at high temperatures are also small, can be widely used in refrigeration equipment; Alloy light weight, low density, price concessions, and shape durability; The size of the alloy die Investment...

Alloy die casting machine is the basis of the die casting alloy die casting equipment, alloy die casting production of various features are done by die casting machine. According to the needs of the die casting technology, provides metal stamping parts favorable conditions for the selection of die casting parameters. The design of die casting mould is closely related to the selection...
