Design of gating system for sand casting coupling parts

In sand casting, the gating system is a reserved channel in the sand mold, which is used to guide the high-temperature metal melt into the casting cavity and continuously complete the filling of the cavity. The main requirements for the gating system are: (1) Rapid pouring: reduce the temperature...

Blank structure of coupling parts of sand casting

The sand casting structure of coupling parts is often simpler than that of finished parts, because many structures of finished sand casting coupling parts can not be obtained directly by casting. The actual finished parts often obtain the approximate structure of parts through casting, and finally obtain the structure...

Surface nitriding defects of precision casting parts

The investment casting method is adopted for precision casting parts. The process is as follows: select appropriate paraffin material to manufacture the investment mold → repeatedly dip refractory sand on the investment mold → harden and dry the shell → melt the internal investment mold to obtain the mold...

Doe analysis of surface nitriding of precision casting parts

The main causes of poor plasma nitriding of precision casting parts are heat treatment temperature, heat treatment time, nitrogen concentration, ammonia concentration, vacuum degree in heat treatment furnace, surface roughness of casting parts, oxidation before quenching and quenching, oxidation before quenching and tempering, oxidation in casting parts and oxidation...

Riser design of coupling parts of sand casting

Riser refers to the structure artificially set in the pouring and riser system to store metal liquid. In the pouring process of sand castings, the riser mainly plays a role in compensating the shrinkage cavity and porosity that may occur in the liquid shrinkage and solidification shrinkage stages in...

Finite element analysis of sand casting coupling parts

1. Structure description of sand casting coupling parts Based on the above reasons, this topic adds the working condition mechanical property analysis of parts to the sand casting process design, and puts this part before the specific sand casting process design, hoping to analyze the weak areas of parts,...
