1, Using short, thin, wide ingate and chill to prevent the shrinkage defects, casting yield was improved by 3%.

2, Based on above analysis, the ingate design and the die structure have been optimized.

3, The results show that the submerged nozzle ingate angle and depth of its immersion should decrease gradually with the lowering of casting speed.

4, Using thin, wide ingate and chill can prevent the shrinkage defect, and improve casting yield by 3%.

5, Acentric ingates are used to set on the moving mould and slag-collector is set at the end of ingate and at converging zone of liquid metal from two sides.

6, The original ingate was enlarged by side cutting and roof cutting under the condition of filling behind wall by grouting, and then be supported and reinforced by the secondary support technology.

7, The general procedures for constructing subway are as follows: first excavate the shaft, then horizontal pass, finally ingate.

8, The production verifies that the desirable filling can be formed in the optimized ingate, which plays the uniform temperature distribution in the die and eliminates the cold shut in fi...

9, Ring pouring channel was set for pouring position. Ladder-like horizontal gate was designed for horizontal gate. Section area of ingate was calculated by the equation.

10, It is found that the shape and size of ingate of thin walled plate casting have a tremendous influence on the temperature field during solidification and its quality.

11, It is suggested to apply the principle of effective gravity and equivalent pressure head to calculate the rotational speed and ingate area in the processing of grinding ball by centrifugal casting.

12, There easily exists shrinkage porosity due to superheat of ingate root in large plain parts investment casting.

13, The results show that the casting with good quality can be obtained by removing one ingate and adding cooling waterway into mould.

14, Improvement of the running system is proposed by the further tests of water simulation, that is,(http:///ingate.html) adjusts the ingate installation to decrease the trapped blowholes.

15, The paper introduced the parameter optimization and construction method of smooth blasting of horse - head ingate.

16, The technology of grinding ball by centrifugal casting, the rotational speed, the method for calculation of ingate area and factors influencing technological process were introduced.

17, The small formation holes in the brush cover was constructed with the mold core in moving and static container, and center ingate was employed to the gating system.

18, The crack in investment castings is commonly created around ingate due to easily forming superheating at root of ingate.

19, Effects of SSS die casting processing parameters on properties of ADC12 aluminum alloy castings were examined by a standard tensile testing specimen with different ingate configurations.
