结合实际分析了Ｖ法造型设备选择和各种材料及工艺参数的选定，生产中型砂水份要严格控制在１％以下；振实台振实时间一般为１０～５０ｓ，每次振动时间应该一致；拔模时真空度低于０．０５ＭＰａ。
In combination with the actual analysis of the V method of modeling equipment selection and selection of various materials and process parameters, the production of sand in the sand should be strictly controlled at 1% or less; Zhenzhaobian real time is generally 10 ~ 50s, each vibration time should be Consistent; vacuum degree when drawing less than 0.05MPa.
