sand casting

John Campbell of the University of Birmingham and others have carried out a lot of research work on the design

Three kinds of Dieless manufacturing processes, including laser selective sintering of coated sand, laser selective sintering of PS powder and

(1) The minimum sectional area of gating system shall be determined. The minimum area of gating system is generally calculated

According to the three carbon source calculation models based on three types of sand casting process parameters, the total carbon

The solidification process of sand castings is directly related to the shrinkage cavity, porosity and stress concentration of sand castings.

1. Sand core design of sand mold casting The core is made of furan resin self hardening sand. Because the

The spiral case is made of QT500-7, and its chemical composition is shown in the table. The production nature of

After the simulation calculation is completed, enter the visual viewer post-processing interface, observe the dynamic change of liquid metal temperature

Compared with other metal castings, sand casting has the advantages of low cost, simple production process and short production cycle.

According to the above anti gravity test results, the differential pressure sand casting process was selected to pour the actual

The wall thickness of the hatch sand casting is 2 mm, and the dimensional accuracy requirements are high. It is

The hatch sand castings are sand castings with overall wall thickness of 2 mm. There is no report on the

The hatch sand casting is a key structural member of aluminum alloy for aircraft. The outline dimension of fad hatch

The figure shows the results of shrinkage porosity after solidification of sand casting frame, and the criterion of casting shrinkage

The figure shows the solidification fraction of the sand casting frame at different times. It can be seen that the
