1) Whether the molten metal can flow smoothly and smoothly in the pouring system without separation and eddy current.
2) Is there a sharp corner zone or a dead zone?
3) Does the gating system have a change in cross-sectional area?
4) Is the position of the exhaust groove and overflow tank correct? Is it big enough? Will it be blocked? Can the gas be effectively and smoothly discharged?
The application of the computer simulation filling process is to analyze the above phenomena and use the judgment to select reasonable process parameters.
(4) Analysis of paint production gas
Coating properties: If the amount of gas generated has a direct impact on the porosity of the casting.
Spraying process: too much use, resulting in a large amount of gas volatilization, too much punch lubricant, or burnt, is a source of gas.
(5) Ways to solve the pores of die-casting parts
First analyze the cause of the stomata, and then take the appropriate measures.
