What is the difference between vertical fire pump die casting and die casting die forging billet? Please refer to Xiao Bian's carefully prepared knowledge analysis. It will definitely help you.
The first refers to rough surface treatment of rough surfaces. Such as aluminum die-casting parts, because of the silicon, the output of the blanks produced by the die-casting process has micropores in the surface layer. This material will have a "black spot" after the anodized surface treatment. Therefore, if the blank requires an anode compound, the traditional die-casting process will not produce a blank;
Second, die-casting parts are usually "structural parts", while die-casting die forgings are "effect parts". Compare "structure" with "effectiveness". The latter's eddy current rate generally refers to impact, high temperature, pressure, strength, surface treatment, heat treatment and other effects. Typical products are engines, hubs, pistons, connecting rods, brake shoes, pneumatic or hydraulic valve bodies. The former such as door frames, instrument panels, engine covers, etc .;
The third is the president from the metallurgical organization. Die casting and die casting die forgings are very, very easy to distinguish between metallurgy. The former is a dendritic as-cast structure, the latter is a forged structure with average broken particles;
The fourth is the composition of publicity materials. Since die castings are usually forged alloys, alloys with other names are usually produced by die casting and die forging processes.
